A new Technique Could use Quasars to Directly Measure the Expansion Rate of the Universe

One of the biggest challenges to measuring the expansion of the universe is the fact that many of the methods we use are model-dependent. The most famous example is the use of distant supernovae, where we compare the standard brightness of a Type Ia supernova with their apparent brightness to find their distance. But knowing the standard brightness depends upon comparing them to the brightness of Cepheid variables which is in turn determined by measuring the distances of nearby stars via parallax. Every step of this cosmic distance ladder depends upon the step before it.

One of the Brightest Star-Forming Regions in the Milky Way, Seen in Infrared

Certain parts of the galaxy are more magical than others. There are barren wastelands where barely a particle strays through occasionally, and there are fantastical nebulae that can literally light up the sky. But beyond their good looks, those nebulae hold secrets to understanding some of the most important features of any galaxy – stars. Now, for the first time, a team from the University of Maryland managed to capture a high resolution image of one of the most active star-forming regions in our part of the galaxy. Data from that image are not only spectacular, but can illuminate the details of the star formation process.

How Do Stars Form?

We owe our entire existence to the Sun. Well, it and the other stars that came before. As they died, they donated the heavier elements we need for life. But how did they form? Stars begin as vast clouds of cold molecular hydrogen and helium left over from the Big Bang. These vast clouds can be hundreds of light years across and contain the raw material for thousands or even millions of times the mass of our Sun. In addition to the hydrogen, these clouds are seeded with heavier elements from the stars that lived and died long ago. They're held in balance between their inward force of gravity and the outward pressure of the molecules. Eventually some kick overcomes this balance and causes the cloud to begin collapsing. That kick could come from a nearby supernova explosion, collision with another gas cloud, or the pressure wave of a galaxy's spiral arms passing through the region. As this cloud collapses, it breaks into smaller and smaller clumps, until there are knots with roughly the mass of a star. As these regions heat up, they prevent further material from falling inward. At the center of these clumps, the material begins to increase in heat and density. When the outward pressure balances against the force of gravity pulling it in, a protostar is formed. What happens next depends on the amount of material. Some objects don't accumulate enough mass for stellar ignition and become brown dwarfs - substellar objects not unlike a really big Jupiter, which slowly cool down over billions of years. If a star has enough material, it can generate enough pressure and temperature at its core to begin deuterium fusion - a heavier isotope of hydrogen. This slows the collapse and prepares the star to enter the true main sequence phase. This is the stage that our own Sun is in, and begins when hydrogen fusion begins. If a protostar contains the mass of our Sun, or less, it undergoes a proton-proton chain reaction to convert hydrogen to helium. But if the star has about 1.3 times the mass of the Sun, it undergoes a carbon-nitrogen-oxygen cycle to convert hydrogen to helium. How long this newly formed star will last depends on its mass and how quickly it consumes hydrogen. Small red dwarf stars can last hundreds of billions of years, while large supergiants can consume their hydrogen within a few million years and detonate as supernovae. But how do stars explode and seed their elements around the Universe? That's another episode.

Black Holes and Dense stars in the Universe

Black Hole Infographic

10 Amazing Facts About Black Holes by Elizabeth Howell on January 22, 2015

An artists illustration of the central engine of a Quasar.
These ?Quasi-stellar Objects? QSOs are now recognized as the super massive black holes
at the center of emerging galaxies in the early Universe. (Photo Credit: NASA)
Imagine matter packed so densely that nothing can escape. Not a moon, not a planet and not even light.
That?s what black holes are ? a spot where gravity?s pull is huge, ending up being dangerous for anything that accidentally strays by.

Black Holes

Computer-Simulated Image of a Supermassive Black Hole

This computer-simulated image shows a supermassive black hole at the core of a galaxy.
The black region in the center represents the black hole�s event horizon, where no light can escape the massive object�s gravitational grip.
The black hole�s powerful gravity distorts space around it like a funhouse mirror. Light from background stars is stretched and smeared
as the stars skim by the black hole. Astronomers have uncovered a near-record breaking supermassive black hole, weighing 17 billion suns,
in an unlikely place: in the center of a galaxy in a sparsely populated area of the universe.
The observations, made by NASA�s Hubble Space Telescope and the Gemini Telescope in Hawaii, may
indicate that these monster objects may be more common than once thought.

Redshift occurs as a result of an object moving away at relativistic speeds (a portion of the speed of light).
For decades, scientists have been using it to determine how fast other galaxies are moving away from our own,
and hence the rate of expansion of the Universe. Relying on optical data obtained by the Subaru telescope,
the CSIRO team was able to obtain both the dispersion and the redshift data from this signal.

A NEW SURVEY TAKES THE HUBBLE DEEP FIELD TO THE NEXT LEVEL,
ANALYZING DISTANCE AND PROPERTIES OF 1,600 GALAXIES

This video gives a close-up view of the Hubble Ultra Deep Field region, a tiny but much-studied region in the constellation of Fornax, as observed with the MUSE instrument on ESO�s Very Large Telescope. But this rich and colourful picture only gives a very partial view of the power of the MUSE data, which also provide a spectrum for each pixel in the picture. This data set has allowed astronomers not only to measure distances for far more of these galaxies than before � a total of 1600 � but also to find out much more about each of them. Surprisingly 72 new galaxies were found that had eluded deep imaging with the NASA/ESA Hubble Space Telescope. More information and download options:

Astronomers using the MUSE instrument on ESO�s Very Large Telescope in Chile have conducted the deepest spectroscopic survey ever. They focused on the Hubble Ultra Deep Field, measuring distances and properties of 1600 very faint galaxies including 72 galaxies that have never been detected before, even by Hubble itself. This wealth of new information is giving astronomers insight into star formation in the early Universe, and allows them to study the motions and other properties of early galaxies � made possible by MUSE�s unique spectroscopic capabilities.

There's a strange place in the sky where everything is attracted. And unfortunately, it's on the other side of the Milky Way, so we can't see it. What could be doing all this attracting?

Superclusters � regions of space that are densely packed with galaxies � are the biggest structures in the Universe. But scientists have struggled to define exactly where one supercluster ends and another begins. Now, a team based in Hawaii has come up with a new technique that maps the Universe according to the flow of galaxies across space. Redrawing the boundaries of the cosmic map, they redefine our home supercluster and name it Laniakea, which means �immeasurable heaven� in Hawaiian. : Read the research paper Read Nature's news story: Category Science & Technology License Standard YouTube License SHOW LESS

New Research Reveals How Galaxies Stay Hot and Bothered

It�s relatively easy for galaxies to make stars. Start out with a bunch of random blobs of gas and dust. Typically those blobs will be pretty warm. To turn them into stars, you have to cool them off. By dumping all their heat in the form of radiation, they can compress. Dump more heat, compress more. Repeat for a million years or so.

This composite image shows the central regions of the nearby Circinus galaxy, located about 12 million light years away. Data from NASA�s Chandra X-ray Observatory is shown in blue and data from the Hubble Space telescope is shown in yellow, red, cyan, and light blue.

Astronomers Process Hubble’s Deepest Image to get Even More Data,
and Show that Some Galaxies are Twice as big as Previously Believed

It allowed us to spot auroras on Saturn and planets orbiting distant suns. It permitted astronomers to see galaxies in the early stages of formation, and look back to some of the earliest periods in the Universe. It also measured the distances to Cepheid variable stars more accurately than ever before, which helped astrophysicists constrain how fast the Universe is expanding (the Hubble Constant).

Watch a Simulation of a Galaxy, From the Big Bang Until the Present Day

Since the mid-20th century, scientists have had a pretty good idea of how the Universe came to be. Cosmic expansion and the discovery of the Cosmic Microwave Background (CMB) lent credibility to the Big Bang Theory, and the accelerating rate of expansion led to theories about Dark Energy. Still, there is much about the early Universe that scientists still don’t know, which requires that they rely on simulations on cosmic evolution.

Formation of a single massive galaxy through time in the TNG50 cosmic simulation

The formation of a single massive galaxy through time, from early cosmic epochs until the present day, in the TNG50 cosmic simulation. The main panel shows the density of the cosmic gas (high in white, low in black). Insets show large-scale dark matter and then gas (lower left), and small-scale stellar and gaseous distributions (lower right). This TNG50 galaxy will be similar in mass and shape to Andromeda (M31) by the time the movie reaches the current epoch. Its progenitor experiences rapid star formation in a turbulent gas reservoir which settles into an ordered disc after a couple of billion years of cosmic evolution. A rather quiet late time assembly history without major mergers allows the galaxy to relax into an equilibrium balance of gas outflows from supernova explosions and gas accretion from its surroundings.

Astronomers Find a Galaxy Containing Three Supermassive Black Holes at the Center

NGC 6240 is a puzzle to astronomers. For a long time, astronomers thought the galaxy is a result of a merger between two galaxies, and that merger is evident in the galaxy’s form: It has an unsettled appearance, with two nuclei and extensions and loops.

New observations show that NGC 6240 is home to three supermassive black holes, not two. The northern (N) black hole was previously known, and is an active hole. The new observations shows that the southern black hole is actually two holes: S1 and S2.

Galaxies Like the Milky Way are the Best for Life

Scientists have speculated that given the sheer number of galaxies in our Universe – modern estimates are as high as 2 trillion – that there must be infinite opportunities for life to emerge. It has also been theorized that galaxies (like stars) have habitable zones, where star systems located too close to the core or too far out in the spiral arms will be exposed to too much radiation for life to emerge.

Does Our Galaxy Have a Habitable Zone? Where Life Can Form in the Milky Way

It’s not just our Solar System that has a habitable zone, it turns out our entire galaxy has regions which would be hostile to the formation of life as we know it.

What Is a Galaxy?

Galaxies are concentrations of stars, gas, dust, and dark matter. They come in a variety of shapes and sizes. Some are fated to collide, like the Milky Way and Andromeda.

This Is Fascinating. An Image of a Galaxy’s Magnetic Field

There’s always more than one way to look at the world. There’s also more than one way to look at a galaxy. And sometimes combining those ways of looking can result in something truly special. That is what happened recently when a team of astronomers from seven different universities in four different countries used three different telescopes to produce an absolutely spectacular image of a galaxy and its surrounding magnetic field. The galaxy in the image is NGC 4217, a spiral galaxy which can be seen edge on in the constellation Ursa Major. It’s similar in shape to the Milky Way and about 67 million light years away. It also has a very large magnetic field.

An Infrared Map of the Universe

This all-sky view of the entire near-infrared sky reveals the distribution of galaxies beyond the Milky Way.
The image is derived from the 2MASS Extended Source Catalog, which contains more than 1.5 million galaxies,
and the Point Source Catalog, which holds nearly 500 million stars within the Milky Way.
The galaxies are color coded for distances obtained by various surveys. The nearest sources are blue,
moderately distant sources are green, and red represents the farthest sources.

NASA Selects New Mission to Explore Origins of Universe


Our Position in the Universe & How did the Universe from the Big Bang???

A Giant Galaxy Seen Lighting Up the Universe Shortly After the Big Bang

About 370,000 years after the Big Bang, the Universe experienced a period that cosmologists refer to as the “Cosmic Dark Ages.” During this period, the Universe was obscured by pervasive neutral gas that obscured all visible light, making it invisible to astronomers. As the first stars and galaxies formed over the next few hundred millions of years, the radiation they emitted ionized this plasma, making the Universe transparent.

If what Meyer and his colleagues observed is typical of reionization-era galaxies, then we can assume that reionization was caused by a small group of galaxies that created large bubbles of ionized gas around them that grew and overlapped. As Meyer explained, this discovery could point the way towards the creation of a new cosmological model that accurately predicts how and when major changes in the early Universe took place:

Did Neutrinos Stop The Early Universe From Annihilating Itself?

We can create matter from energy in the lab. Particle accelerators do this all the time. When we do, half of what is created is matter and the other half antimatter. There is a symmetry in physics that requires matter and antimatter to appear in equal amounts. But when we look around the universe, what we see is matter. So how did the big bang create all the matter we see without creating an equal amount of antimatter? The answer could be neutrinos.

Fundamental symmetries in physics. Credit: Flip Tanedo One of the fundamental symmetries in physics is the conservation of charge. The total charge in the universe is zero, and that can’t change. So if you create a charged particle of matter, you must also create a corresponding antimatter particle with the opposite charge. This symmetry is so central to physics that astronomers think the big bang created matter and antimatter in equal amounts. Soon afterward, something must have happened to leave the universe with more matter than antimatter.

Left-handed and right-handed chirality. Credit: Wikipedia Every elementary particle has a rotation-like property known as spin. When a particle is shooting through space, the spin and motion can point along its direction of motion, or opposite to its motion. The former is known as right-handed chirality, while the latter is left-handed. Both matter and antimatter particles can have either chirality, except for the neutrino. Neutrinos are always left-handed, and anti-neutrinos are always right-handed.

So how did the big bang create all the matter we see without creating an equal amount of antimatter? The answer could be neutrinos. Matter and antimatter are kind of like cosmic twins. For every type of matter particle, there is a corresponding antimatter particle. The main difference between the two is their electric charge. For example, an electron has a negative charge, while the anti-electron (commonly called the positron) has a positive charge. Protons have a positive charge, while anti-protons have a negative one.

Credit: R.Hurt/Caltech-JPL, NASA, and ESA, with modifications by Kavli IPMU The idea is that very soon after matter and antimatter appeared in the cosmos, the universe underwent a phase change where more antimatter converted into heavy anti-neutrinos than matter converted into heavy matter neutrinos. The total charge of the universe remained zero, and the matter-antimatter balance is preserved, but what remained was mostly regular matter and heavy anti-neutrinos.

Scientists are fairly certain that, one day, our universe will come to an end. Here's how they think this might happen.

Life Could be Common Across the Universe, Just Not in Our Region

Logarithmic scheme of the observable universe with some of the notable astronomical objects known today. From left to right the celestial bodies are arranged according to their proximity to Earth. In the left border, Earth and near-Earth objects are depicted.

Logarithms help us make sense of huge numbers, and in this case, huge distances. Rather than showing all parts of the universe
on a linear scale, each chunk of the circle represents a field of view several orders of magnitude larger than the one before it.
That's why the entire observable universe can fit inside the circle.

How Big Is The Universe?

The Universe is big, but how big is it? That all depends on whether the Universe is finite or infinite. Even the word "big" is tough to get clear. Are we talking about the size of the Universe we can see, or the Universe's actual size right now?

Illustris Simulation: Most detailed simulation of our Universe

The Illustris simulation is the most ambitious computer simulation of our Universe yet performed. The calculation tracks the expansion of the universe, the gravitational pull of matter onto itself, the motion of cosmic gas, as well as the formation of stars and black holes. These physical components and processes are all modeled starting from initial conditions resembling the very young universe 300,000 years after the Big Bang and until the present day, spanning over 13.8 billion years of cosmic evolution. The simulated volume contains tens of thousands of galaxies captured in high-detail, covering a wide range of masses, rates of star formation, shapes, sizes, and with properties that agree well with the galaxy population observed in the real universe. The simulations were run on supercomputers in France, Germany, and the US. The largest was run on 8,192 compute cores, and took 19 million CPU hours. A single state-of-the-art desktop computer would require more than 2000 years to perform this calculation.

Major New Cosmic Simulation: Why it's Significant

Scientists have created an important new simulation of cosmic evolution. It takes place in a virtual cube 350 million light-years squared, and spans a time period from 12 million years after the Big Bang to the present day, or around 13 billion years' worth of cosmic evolution. The project, called Illustris, encompasses over 12 billion data points to track the rise and evolution of some 50,000 galaxies. The simulation used a total of 8,000 processors, the equivalent of 2,000 years of processing time on a standard desktop computer. The run created half-petabyte of information. The end result is a model that not only recreates the emergence of stars and galaxies, but the influence of dark matter and the spread of heavy metals throughout the universe.

Meet Our Neighbour, The Local Void. Gaze Into It, Puny Humans.

Our planet is part of the larger structure of the Solar System, shaped and made stable by the force of gravity. Our Solar System is gravitationally bound to the Milky Way galaxy, along with hundreds of millions of other solar systems. And our galaxy is also part of a larger structure, where not only gravity, but the expansion of the Universe, shapes and molds that structure. For regular Universe Today readers, none of that is news.

Laniakea: Our home supercluster

Superclusters – regions of space that are densely packed with galaxies – are the biggest structures in the Universe. But scientists have struggled to define exactly where one supercluster ends and another begins. Now, a team based in Hawaii has come up with a new technique that maps the Universe according to the flow of galaxies across space. Redrawing the boundaries of the cosmic map, they redefine our home supercluster and name it Laniakea, which means ‘immeasurable heaven’ in Hawaiian.

Astronomers Spot Distant Galaxy Group Driving Ancient Cosmic Makeover


The solar system and beyond

By looking deeper into space (and farther back in time), astronomers and cosmologists continue to push the boundaries of what is known about the Universe. Thanks to improvements in instrumentation and observation techniques, we are now at the point where astronomers are able to observe some of the earliest galaxies in the Universe – which in turn is providing vital clues about how our Universe evolved.

Visualization: How UV Light From 1st Stars, Galaxies Transformed Universe

This visualization shows how ultraviolet light from the first stars and galaxies gradually transformed the universe. Hydrogen atoms, also called neutral hydrogen, readily scatters UV light, preventing it from traveling very far from its sources. Gradually, intense UV light from stars and galaxies split apart the hydrogen atoms, creating expanding bubbles of ionized gas. As these bubbles grew and overlapped, the cosmic fog lifted. Astronomers call this process reionization. Here, regions already ionized are blue and translucent, areas undergoing ionization are red and white, and regions of neutral gas are dark and opaque.

WFIRST: The Best of Both Worlds

NASA officially is beginning work on an astrophysics mission designed to help unlock the secrets of the universe -- the Wide Field Infrared Survey Telescope (WFIRST). With a view 100 times bigger than that of NASA’s Hubble Space Telescope, WFIRST will aid researchers in their efforts to unravel the secrets of dark energy and dark matter, and explore the evolution of the cosmos. It also will discover new worlds outside our solar system and advance the search for worlds that could be suitable for life. WFIRST is the agency's next major astrophysics observatory, following the launch of the James Webb Space Telescope in 2018. The observatory will survey large regions of the sky in near-infrared light to answer fundamental questions about the structure and evolution of the universe, and expand our knowledge of planets beyond our solar system, known as exoplanets. It will carry a Wide Field Instrument for surveys, and a Coronagraph Instrument designed to block the glare of individual stars and reveal the faint light of planets orbiting around them. By blocking the light of the host star, the Coronagraph Instrument will enable detailed measurements of the chemical makeup of planetary atmospheres. Comparing these data across many worlds will allow scientists to better understand the origin and physics of these atmospheres, and search for chemical signs of environments suitable for life. The telescope’s sensitivity and wide view will enable a large-scale search for exoplanets by monitoring the brightness of millions of stars in the crowded central region of our galaxy. The survey will net thousands of new exoplanets similar in size and distance from their star as those in our own solar system, complementing the work started by NASA's Kepler mission and the upcoming work of the Transiting Exoplanet Survey Satellite. Employing multiple techniques, astronomers also will use WFIRST to track how dark energy and dark matter have affected the evolution of our universe. Dark energy is a mysterious, negative pressure that has been speeding up the expansion of the universe. Dark matter is invisible material that makes up most of the matter in our universe. By measuring the distances of thousands of supernovae, astronomers can map in detail how cosmic expansion has increased with time. WFIRST also can precisely measure the shapes, positions and distances of millions of galaxies to track the distribution and growth of cosmic structures, including galaxy clusters and the dark matter accompanying them. WFIRST is slated to launch in the mid-2020s. The observatory will begin operations after traveling to a gravitational balance point known as Earth-Sun L2, which is located about one million miles from Earth in a direction directly opposite the sun. WFIRST is managed at NASA's Goddard Space Flight Center in Greenbelt, Maryland, with participation by NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, the Space Telescope Science Institute in Baltimore, the Infrared Processing and Analysis Center, also in Pasadena, and a science team comprised of members from U.S. research institutions across the country.

The Largest Rotating Objects in the Universe: Galactic Filaments Hundreds of Millions of Light-Years Long

We’ve known for a while about the large-scale structure of the Universe. Galaxies reside in filaments hundreds of millions of light-years long, on a backbone of dark matter. And, where those filaments meet, there are galaxy clusters. Between them are massive voids, where galaxies are sparse. Now a team of astronomers in Germany and their colleagues in China and Estonia have made an intriguing discovery.

This figure from the paper shows the filament rotation speed as a function of the distance between galaxies and the filament spine. The distance of galaxies from the filament spine in the receding region is displayed in red and ascribed positive values, while the distance of galaxies in the approaching region is marked in blue and ascribed negative values. Error bars represent the standard deviation about the mean. Image Credit: Wang et al 2021.

New Radio Images of Bizarre “Odd Radio Circles” Which are Vastly Bigger Than the Milky Way

In radio astronomy, circle-shaped objects are fairly common. Since diffuse ionized gas often emits radio light, objects such as supernova remnants, planetary nebulae, and even star-forming regions can create circular arcs of diffuse gas. But in 2019 astronomers began to discover radio circles they couldn’t explain, in part because they are so large.

Expanding the Frontiers of Space Astronomy

The universe is cold and dark. And yet, within the dark, there is a faint glow of warmth. Across the sky, there are objects that emit infrared light, similar to the light that warms your hands near a campfire. By observing this light, astronomers can see the cosmos in a way that looks very different from that seen by our eyes.

JWST Turns Its Gaze on the Cartwheel Galaxy

This image of the Cartwheel and its companion galaxies is a composite from Webb’s Near-Infrared Camera (NIRCam) and Mid-Infrared Instrument (MIRI). Courtesy NASA, ESA, CSA, STScI.

The mid-infrared light captured by MIRI reveals chemical details about dusty regions in the Cartwheel and young stars it contains. Young stars, many of which are present in the bottom right of the outer ring, energize surrounding hydrocarbon dust, causing it to glow orange. On the other hand, the clearly defined dust between the core and the outer ring forms the “spokes” that inspire the galaxy’s name. This dust feeds the supermassive black hole in the center of the galaxy.

The Cartwheel is part of a group of four galaxies, as shown in this collage of images from ground-based optical and radio telescopes and the Hubble Space Telescope’s Wide Field and Planetary Camera 2.

Thank you ALMA OBSERVATORY

Astronomers watch the aftermath of a star ripped apart by a huge black hole



Here's the deal. In the center of every big galaxy is a big black hole, one so big we call it supermassive. When the Universe was young this central black hole formed along with its galaxy, and in many ways the two affect each other as they both grow. Over time, as the galaxy grows big, so does that beast in the middle.

The Square Kilometer Telescope proposal

The Atacama Large Millimeter/Sub-millineter Array (ALMA).
