Listed in the Almagest –a star catalog written by Ptolemy around A.D. 150 –Alpha Centauri was documented in antiquity and has always been an object of curiosity for astronomers. Despite it being documented so early, it was not until the late 1600s when the astronomers realized that it was a multi-star stellar system –meaning it was made up of three stars: Alpha Centauri A, Alpha Centauri B, and Alpha Centauri C. Our universe is a vast and mysterious place, full of secrets waiting to be unveiled. Sure, our world –in fact, our entire solar system –revolves around the only star visible to our eyes: the Sun. However, at our very doorstep lies our closest neighbor: The Alpha Centauri System. The multi-star system is not only the closest star system to our solar system, but it is also surrounded by mysteries along with many unanswered questions–one of them is the possibility of extraterrestrial life in the Alpha Centauri System. Robert Innes, who made significant contributions to the study of astronomy and helped unlock some of the universe's secrets. 00:00 Introduction 00:59 Robert innis and Alpha Centauri 04:14 How far Alpha Centauri really is ? 05:08 From how far we have been able to receive signals ? 06:52 Alpa centauri 20:23 Humans on proxima b
Alpha Centauri is the closest star system to us at about four light years away but it would take us thousands of years to get there by rocket. Some people just don't have that much patience.

Can you imagine what the spaceships of the future will be like? Imagine that spaceships will use nuclear energy as fuel in the future! Would those spacecraft be fast enough to reach the closest star to the Sun? And if so, who will go aboard those spaceships? Who would be the first to reach Alpha Centauri? Currently, spaceships, even humanity's most advanced and powerful, have many problems getting out of the solar system. This is mainly due to two factors; the first is that the universe is vast, it is immense, and the distances that separate all celestial bodies are so enormous that they cannot be measured in kilometers but rather in astronomical units and light years. An astronomical unit is the average distance between the Sun and Earth, equivalent to approximately 92.96 million miles (149.6 million kilometers). The problem of going out To date, no human-created spacecraft has managed to leave the solar system. Technologies that already exist In past videos, we have talked about the different technologies that could exist in the future to travel to Alpha Centauri. However, most of them remain in speculation as they do not exist yet. Temporary dilation Time dilation is a phenomenon that arises from Einstein's theory of relativity; in simple terms, it means that time can pass slower or faster depending on the speed and gravity in which you find yourself. What technology will be chosen? That said, considering the trip to Alpha Centauri will take more than 80 years, what technology would be chosen to do it? 1. Nuclear Fusion Propulsion Nuclear fusion propulsion is a space propulsion concept based on the use of energy generated by controlled nuclear fusion. 2. Nuclear Pulse Propulsion Pulse nuclear propulsion, also known as pulsed nuclear explosion nuclear propulsion, is a space propulsion concept that involves using controlled nuclear explosions to generate impulses and propel a spacecraft. 3. Solar sail propulsion Solar sail propulsion is a theoretical space propulsion method based on harnessing the pressure of solar radiation to propel a spacecraft. It uses a very light and large sail or reflector, known as a solar sail, which reflects solar radiation. 4. Laser propulsion Laser propulsion is a space propulsion concept that relies on using a high-powered laser beam to propel a spacecraft. -- DISCUSSIONS & SOCIAL MEDIA E-mail for Commercial Purposes: Tik Tok: reddit:Insane curisoty Instagrsm Insane curisty Twitter: Facebook: Insane curisoty Linked in Our Website: -- Credits: Ron Miller, Mark A.

When exploring other planets and celestial bodies, NASA missions are required to abide by the practice known as “planetary protection“. This practice states that measures must be taken during the designing of a mission to ensure that biological contamination of both the planet/body being explored and Earth (in the case of sample-return missions) are prevented.

The distances between stars are so vast, it’s hard to wrap your mind around it. Even our far flung Voyagers have barely reached interstellar space, and would take tens of thousands of years to get to even the nearest star. But scientists and engineers are considering what it would actually take to send a spacecraft to another star. It’s called Project Dragonfly, and would use existing or near future technologies to send a 3,000 kg spacecraft to Alpha Centauri within 100 years.

What these observations showed was that any planet orbiting within the habitable zone of A would receive (on average) a lower dose of X-rays compared to similar planets around the Sun. For planets orbiting withing the habitable zone of B, the X-ray dose they received would be about five times higher. Meanwhile, planets orbiting within Proxima Centauri’s habitable zone would get an average of 500 times more X-rays, and 50,000 times more during a big flare
At a distance of only 25 trillion miles, the Alpha Centauri star system is a prime target in humanity's search for life outside our Solar System. Astronomers would like to know what kind of environment exists around the two stars in Alpha Centauri that closely resemble our Sun. To learn about this, NASA's Chandra X-ray Observatory has been monitoring the Alpha Centauri system every six months for over a decade. Chandra is the only X-ray observatory capable of resolving the two Sun-like stars to determine which star is doing what. A new study indicates these two stars are likely not pummeling any orbiting planets with large amounts of X-ray radiation. This is promising news for the sustainability of life on any planets astronomers find around these two nearby stars in the future.

As the only X-ray observatory capable of resolving Alpha Centauri A and B during its current close orbital approach, Chandra observed these two main stars every six months for the past thirteen years. These long-term measurements captured a full cycle of increases and decreases in X-ray activity, in much the same way that the Sun has an 11-year sunspot cycle.

In a generic brick building on the northwestern edge of NASA’s Goddard Space Flight Center campus in Greenbelt, Maryland, thousands of computers packed in racks the size of vending machines hum in a deafening chorus of data crunching. Day and night, they spit out five quadrillion calculations per second. Known collectively as the Discover supercomputer, these machines are tasked with running sophisticated climate models to predict Earth’s future climate. But now, they’re also sussing out something much farther away: whether any of the more than 4,000 curiously weird planets beyond our solar system — or exoplanets — discovered in the past two decades could have the ingredients necessary to support life.

In 2016, astronomers working for the European Southern Observatory (ESO) confirmed the existence of a terrestrial planet around Earth’s closest stellar neighbor – Proxima Centauri. The discovery of this nearby extrasolar planet (Proxima b) caused no shortage of excitement because, in addition to being similar in size to Earth, it was found to orbit within the star’s habitable zone (HZ).

However, this particular set of data was gathered during the four-year SpHere INfrared survey for Exoplanets (SHINE) survey, where SPHERE was used to image 600 nearby stars in the near-infrared spectrum

That means that light, traveling at 300,000 kilometers per second would still need 4 YEARS to reach the nearest star. The fastest spacecraft ever launched by humans would need tens of thousands of years to make that trip. But science fiction encourages us to think it’s possible. Kirk and Spock zip from world to world with a warp drive violating the Prime Directive right in it’s smug little Roddenberrian face. Han and Chewy can make the Kessel run in only 12 parsecs, which is confusing and requires fan theories to resolve the cognitive space-distance dissonance, and Galactica, The SDF 3, and Guild Navigators all participate in the folding of space.
There’s no two-ways about it, the Universe is an extremely big place! And thanks to the limitations placed upon us by Special Relativity, traveling to even the closest star systems could take millennia. As we addressed in a previous article, the estimated travel time to the nearest star system (Alpha Centauri) could take anywhere from 19,000 to 81,000 years using conventional methods.
Proxima Centauri: The Closest Star Image Credit: ESA/Hubble & NASA Explanation: Does the closest star to our Sun have planets? No one is sure -- but you can now follow frequent updates of a new search that is taking place during the first few months of this year. The closest star, Proxima Centauri, is the nearest member of the Alpha Centauri star system. Light takes only 4.24 years to reach us from Proxima Centauri. This small red star, captured in the center of the featured image by the Hubble Space Telescope, is so faint that it was only discovered in 1915 and is only visible through a telescope. Telescope-created X-shaped diffraction spikes surround Proxima Centauri, while several stars further out in our Milky Way Galaxy are visible in the background. The brightest star in the Alpha Centauri system is quite similar to our Sun, has been known as long as recorded history, and is the third brightest star in the night sky. The Alpha Centauri system is primarily visible from Earth's Southern Hemisphere. Starting last week, the European Southern Observatory's Pale Red Dot project began investigating slight changes in Proxima Centauri to see if they result from a planet -- possibly an Earth-sized planet. Although unlikely, were a modern civilization found living on a planet orbiting Proxima Centauri, its proximity makes it a reasonable possibility that humanity could communicate with them. #PaleRedDot : Follow the search for planets around Proxima Centauri.

The Proposed Bussard RamJet
Forty-one years after it launched into space, NASA’s Voyager 2 probe has exited our solar bubble and entered the region between stars. Its twin, Voyager 1, made this historic crossing in 2012. Edward Stone, the Voyager mission’s project scientist, and Suzanne Dodd, the mission project manager, discuss this major milestone and what’s to come for the trailblazing probe. For more about the Voyagers, including the Grand Tour of the Solar System and the Golden Record, visit NASA's Voyager's webpage

The distances between stars are so vast, it’s hard to wrap your mind around it. Even our far flung Voyagers have barely reached interstellar space, and would take tens of thousands of years to get to even the nearest star. But scientists and engineers are considering what it would actually take to send a spacecraft to another star. It’s called Project Dragonfly, and would use existing or near future technologies to send a 3,000 kg spacecraft to Alpha Centauri within 100 years.

Is there an alien civilization next door? It’s…possible(ish). In late 2020, we discovered a signal from the direction of Proxima Centauri (not necessarily from Proxima Centauri), our closest neighbour star. Named BLC- 1 by project Break Through Listen, the signal is still being analyzed to ensure it isn’t simply an echo of our own civilization – typically what they turn out to be. But why not just directly look at planets in Proxima Centauri and see if a civilization is there?

Music by Mark Hutson - "Endless Void" Space Station Facts: 230 individuals from 18 countries have visited the International Space Station The space station has been continuously occupied since November 2000 An international crew of six people live and work while traveling at a speed of five miles per second, orbiting Earth about every 90 minutes. In 24 hours, the space station makes 16 orbits of Earth, traveling through 16 sunrises and sunsets Peggy Whitson set the record for spending the most total time living and working in space at 665 days on Sept. 2, 2017 The acre of solar panels that power the station means sometimes you can look up in the sky at dawn or dusk and see the spaceship flying over your home, even if you live in a big city. Find sighting opportunities at The living and working space in the station is larger than a six-bedroom house (and has six sleeping quarters, two bathrooms, a gym, and a 360-degree view bay window). To mitigate the loss of muscle and bone mass in the human body in microgravity, the astronauts work out at least two hours a day. Astronauts and cosmonauts have conducted more than 205 spacewalks (and counting!) for space station construction, maintenance and repair since December 1998 The solar array wingspan (240 feet) is about the same length as the world’s largest passenger aircraft, the Airbus A380.

Astronomers have discovered thousands of exoplanets, and still need to confirm thousands more. And over the coming decades, we’ll probably learn of millions of planets, orbiting stars we’ve never heard of. That’s why it’s reassuring to know astronomers are learning a tremendous amount about the closest star system to our own, Proxima Centauri. In fact, we now know of two planets orbiting the red dwarf star, one of which is in the habitable zone. Thumbnail credit: NASA/Harvard-Smithsonian Center for Astrophysics/D. Aguilar Our Book is out!

This infographic compares the orbit of the planet around Proxima Centauri (Proxima b) with the same region of the Solar System. Proxima Centauri is smaller and cooler than the Sun and the planet orbits much closer to its star than Mercury. As a result it lies well within the habitable zone, where liquid water can exist on the planet’s surface.

Beatty (2021) Figure 5 The above figure from Beatty’s publication shows the trade offs between the distance from Earth, the level of urbanization, and the class of parent star. The first two variables, level of urbanization and distance from Earth, are self evident. The brighter the artificial lights, the easier they are to see. If the planet resides closer to Earth, its lights are easier to see. But the parent star also plays a role in visibility. Planets orbiting smaller, dimmer stars have better contrast. Their stars are faint enough to not overwhelm artificial illumination and so lower levels of urbanization can be seen on planets in M red dwarf star systems. The figure’s blue colour shade indicates the certainty of detection. 1 sigma (the Greek letter that’s denoted in the figure) is about 67% certainty. 3 sigma is closer to 99%. 10 sigma is virtually 100%.

#universum #Astronomy #space ♺ DETAILS __________________________________ Tau Ceti, Latinized from τ Ceti, is a single star in the constellation Cetus that is spectrally similar to the Sun, although it has only about 78% of the Sun's mass. At a distance of just under 12 light-years (3.7 parsecs) from the Solar System, it is a relatively nearby star and the closest solitary G-class star. The star appears stable, with little stellar variation, and is metal-deficient relative to the Sun. It can be seen with the unaided eye with an apparent magnitude of 3.5. As seen from Tau Ceti, the Sun would be in the northern hemisphere constellation Boötes with an apparent magnitude of about 2.6.

You Are Not Ready For The Best Merch In The World! 🚀👉 / @insanecuriosity E-MAIL:Commercial Purposes ► Our New Website ► -- Alpha Centauri: the star system that contains our Earth 2.0. Those unfamiliar with all things astronomical sometimes get a little confused when they hear about the closest star to Earth... Alpha Centauri? Beta Centauri? Proxima Centauri? Which star will be the right one? What do you say we go for a ride over there to remove any doubts about it? Alpha Centauri, also known as Rigel Kentaurus or Rigil Kent or, more rarely, as Toliman, is the brightest star in the Centaurus constellation and the third brightest star in the night sky to the naked eye after Sirius and Canopus. Today we know that the primary star in the system (Alpha Centauri A) is a yellow star very similar to our Sun, slightly larger and more massive, while the secondary component (Alpha Centauri B) is orange, slightly smaller and more massive. However, both components are stars whose age, according to current models of stellar evolution, would range between 5 and 6 billion years, making them the same age or slightly older than the Sun. From Earth to his brother Proxima Centauri in 20 years? The project Breakthrough Starshot" In 2016, the La Silla Observatory in Chile identified Proxima b, the closest exoplanet known to us today: it orbits in the habitable belt of its own star, Proxima Centauri, a red dwarf located 4.2 light years away. from us, in the direction of the Centaurus constellation. Proxima Centauri is part of the Alpha Centauri system, a triple system consisting of a yellow dwarf and an orange dwarf very close to each other and from Proxima. Proxima is a red dwarf, probably the most widespread stellar type in the Milky Way -- "If You happen to see any content that is yours, and we didn't give credit in the right manner please let us know at Lorenzovareseaziendale@gmail.com and we will correct it immediately" "Some of our visual content is under an Attribution-ShareAlike license. in its different versions such as 1.0, 2.0, 3,0, and 4.0 – permitting commercial sharing with attribution given in each picture accordingly in the video."
