Visible Light from a Black Hole Spotted by Telescope, a First by Charles Q. Choi, Space.com Contributor | January 06, 2016 01:01pm ET

For the first time, astronomers have seen dim flickers of visible light from near a black hole,
researchers with an international science team said. In fact, the light could be visible to anyone with a moderate-size telescope.

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.

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.

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.

The Party's Over for These Youthful Compact Galaxies

ABOUT THIS IMAGE: This graphic illustrates how a vibrant, star-forming galaxy quickly transforms
into a sedate galaxy composed of old stars. The scenario begins when two galaxies merge
(Panel 1),funneling a large amount of gas into the central region. The gas compresses, sparking a firestorm of star birth,
(Panel 2) which blows out most of the remaining star-forming gas
.(Panel 3). Devoid of its fuel, the galaxy settles into a quiet existence, composed of aging stars Image Type: Illustration Illustration Credit: NASA, ESA, and A. Feild (STScI) Science Credit: P. Sell (Texas Tech University)

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

Images from the Hubble Ultra Deep Field (HUDF). Credit: NASA/ESA/S. Beckwith (STScI)/HUDF Team

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.

The Most Massive Galaxies Spin More Than Twice as Fast as the Milky Way

Pictured M-77 It’s a difficult thing to wrap your head around sometimes. Though it might feel stationary, planet Earth is actually moving at an average velocity of 29.78 km/s (107,200 km/h; 66600 mph). And yet, our planet has nothing on the Sun itself, which travels around the center of our galaxy at a velocity of 220 km/s (792,000 km/h; 492,000 mph).

This Star has been Kicked Out of the Milky Way. It Knows What It Did.

Every once in a while, the Milky Way ejects a star. The evicted star is typically ejected from the chaotic area at the center of the galaxy, where our Super Massive Black Hole (SMBH) lives. But at least one of them was ejected from the comparatively calm galactic disk, a discovery that has astronomers rethinking this whole star ejection phenomenon.

IRRGANG, FAU) Astronomers have discovered a bright, young star that is running away from home. Why? What did the star's parents do to deserve this? According to a study published Aug. 6 in the journal Astronomy & Astrophysics, it's nobody's fault; it seems the young star simply fell in with the wrong crowd — namely, a very hungry black hole.

Monica Valluri and Kohei Hattori tracked a hypervelocity star called LAMOST-HVS1, a hypervelocity star that is closer to the Sun any other. They used one of the Magellan telescopes to measure the star’s velocity and position. Then they joined with other colleagues and combined their data with data from the ESA’s Gaia mission to trace the hypervelocity’s trajectory back to its origin. They were surprised when the origin of the star was not the bulge, but the galactic disk.

Star clusters like the Trapezium cluster in Orion are embedded in gas and dust in the galactic disk and are very difficult to see. There may be a cluster similar to this in the Norma spiral arm, the origin of the hypervelocity star LAMOST-HVS1. Image Credit: By NASA/CXC/Penn State/E.Feigelson & K.Getman et al. Public Domain,

Astronomers are Finding Binary Pairs of Stars Thrown out of Galaxies Together

A rogue star is one that has escaped the gravitational pull of its home galaxy. These stars drift through intergalactic space, and so are sometimes called intergalactic stars. Sometimes, when a rogue star is ejected from its galaxy, it drags its binary pair along for the ride.

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.

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

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.

The Universe is big!!!!

What Is The Habitable Zone?

We've found hundreds of exoplanets in the galaxy. But only a few of them have just the right combination of factors to hold life like Earth's. The weather in your hometown is downright uninhabitable. There�s scorching heatwaves, annual tyhpoonic deluges, and snow deep enough to bury a corn silo. The bad news is planet Earth is the only habitable place we know of in the entire Universe. Also, are the Niburians suffering from Niburian made climate change? Only Niburian Al Gore can answer that question. We as a species are interested in habitability for an assortment of reasons, political, financial, humanitarian and scientific. We want to understand how our own climate is changing. How we�ll live in the climate of the future and what we can do to stem the tide of what our carbon consumption causes. There could be agendas to push for cleaner energy sources, or driving politicians towards climate change denial to maintain nefarious financial gain. We also might need a new lilypad to jump to, assuming we can sort out the travel obstacles. The thing that interests me personally the most is, when can I see an alien? The habitable zone, also known as the �Goldilocks Zone�, is the region around a star where the average temperature on a planet allows for liquid water with which to make porridge. It�s that liquid water that we hunt for not only for our future uses, but as an indicator of where alien life could be in the Universe. Problems outside this range are pretty obvious. Too hot, it�s a perpetual steam bath, or it produces separate piles of hydrogen and oxygen. Then your oxygen combines with carbon to form carbon dioxide, and then hydrogen just buggers off into space. This is what happened with Venus. If the planet�s too cold, then bodies of water are solid skating rinks. There could be pockets of liquid water deep beneath the icy surface, but overall, they�re bad places to live. We�ve got this on Mars and the moons of Jupiter and Saturn. The habitable zone is a rough measurement. It�s a place where liquid water might exist. Unfortunately, it�s not just a simple equation of the distance to the star versus the amount of energy output. The atmosphere of the planet matters a lot. In fact, both Venus and Mars are considered to be within the Solar System�s habitable zone. Venusian atmosphere is so thick with carbon dioxide that it traps energy from the Sun and creates an inhospitable oven of heat that would quickboil any life faster than you can say �pass the garlic butter�. It�s the opposite on Mars. The thin atmosphere won�t trap any heat at all, so the planet is bun-chillingly cold. Upgrade the atmospheres of either planet and you could get worlds which would be perfectly reasonable to live on. Maybe if we could bash them together and we could spill the atmosphere of one onto the other? Tell Blackbolt to ring up Franklin Richards, I have an idea! When we look at other worlds in the Milky Way and wonder if they have life, it�s not enough to just check to see if they�re in the habitable zone. We need to know what shape their atmosphere is in. Astronomers have actually discovered planets located in the habitable zones around other stars, but from what we can tell, they�re probably not places you�d want to live. They�re all orbiting red dwarf stars. It doesn�t sound too bad to live in a red tinted landscape, provided it came with an Angelo Badalamenti soundtrack, red dwarf stars are extremely violent in their youth. They blast out enormous solar flares and coronal mass ejections. These would scour the surface of any planets caught orbiting them close enough for liquid water to be present. There is some hope. After a few hundred million years of high activity, these red dwarf stars settle down and sip away at their fuel reserves of hydrogen for potentially trillions of years. If life can hold on long enough to get through the early stages, it might have a long existence ahead of it. When you�re thinking about a new home among the stars, or trying to seek out new life in the Universe, look for planets in the habitable zone. As we�ve seen, it�s only a rough guideline. You probably want to check out the place first and make sure it�s truly liveable before you commit to a timeshare condo around Gliese 581.

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.

NGC 6725

This video takes the viewer on a journey to the globular cluster NGC 6752. The final view, from the NASA/ESA Hubble Space Telescope, shows the bright stars of the cluster, as well as a collection of faint stars; these faint stars are actually part of a background galaxy, which was discovered accidentally by astronomers studying the cluster itself. The galaxy is about 30 million light-years away, is classified as a dwarf spheroidal galaxy and has been nicknamed Bedin 1, after the principal investigator.

NASA is building up a map of the entire sky seen in X-rays, line by line with its NICER experiment

In June of 2017, NASA’s Neutron Star Interior Composition Explorer (NICER) was installed aboard the International Space Station (ISS). The purpose of this instrument is to provide high-precision measurements of neutron stars and other super-dense objects that are on the verge of collapsing into black holes. NICER is also be the first instrument designed to test technology that will use pulsars as navigation beacons.

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.
