We record the Weekly Space Hangout every Wednesday at 5:00 pm Pacific / 8:00 pm Eastern. You can watch us live on Universe Today or the Weekly Space Hangout YouTube page. This week we welcome Dr. Marina Kounkel, a postdoctoral scholar in the Physics and Astronomy Department at the Western Washington University. Her research focuses on observing the dynamics of young stars. Marina is co-author, with Kevin Covey (also from WWU,) of the peer-reviewed study titled ""Untangling the Galaxy I: Local Structure and Star Formation History of the Milky Way"" published in ""The Astronomical Journal"" in August 2019. Using a machine-learning algorithm to analyze motion and position data obtained by Gaia for over a billion stars, almost 2000 new star clusters and co-moving groups of stars - Sibling Stars if you will - have been identified, all of which lie within ~3000 light years from us. In addition, as part of this study, the ages for hundreds of thousands of additional stars have been determined thus allowing star families to be tracked which provides further insight into how these stars have migrated throughout our galaxy. According to Marina, “Around half of these stars are found in long, string-like configurations that mirror features present within their giant birth clouds.” By studying these strings, we may gain insight into how the Milky Way has evolved. To learn more about Marina, visit her website http://mkounkel.com/ Want to know more about Marina's study and how these strings can further our understanding of galaxy evolution?

Not only is TESS finding worlds around other stars, but it’s keeping a vigilant eye on the rest of the galaxy to find things just like this. According to NASA, capturing this event is hard, it only happens once every ten to a hundred thousand years in our galaxy. #TESS #BlackHoles Join our Chat on Discord here: https://discord.gg/nqGpvtK Follow DeepAstronomy on Twitter: @DeepAstronomy Like DeepAstronomy on Facebook: https://www.facebook.com/DeepAstronomy/

In 2015, astronomers had been trying to find the cause of Tabby's Star's mysterious behavior. The star kept dimming in an oddly sporadic pattern, and overall got 10% less bright in just a century. Some scientists have suggested an alien megastructure or a massive swarm of comets may be to blame. In 2019, a team of astrophysicists at Columbia University proposed a different culprit. The star has stolen icy moons from an orbiting planet. Over time, radiation dissolved these moons, creating a dusty cloud that blocks some of the starlight.

How stars work was a mystery until the early 20th century when astronomers learned to decode stars' spectra. Spectroscopy allowed stars' chemical make-up, temperature, and luminosity to be directly measured. Thanks to a spectral classification system developed by Annie Jump Cannon, and the Hertzsprung-Russell diagram, it became possible to understand how stars are classified, and how stars live and evolve from the main sequence to red giant to white dwarfs. 🔔 Subscribe for more: https://www.youtube.com/christianready?sub_confirmation=1 🚀 Sponsored by MagellanTV - a new streaming service with 2,000+ documentaries worth watching.

The "WTF” star - or "where's the flux?" star - is a star that was spotted by citizen scientists on the Planet Hunters website. It doesn't have regular dips in its brightness like those caused by planets; instead, the dips we see have no pattern at all. What could be responsible for this weird behaviour? Astronomers thought they'd cracked this one two years ago but new data came to light and it's still an unsolved mystery...

When considering star size, we are incredibly restricted with what we can't measure - the vast majority of the universe's stars lie outside of our galaxy, and are too far away to ever be measured. In spite of this, we have discovered some truly magnificent stars in our own backyard. Today, we will be looking at the biggest - UY Scuti. This magnificent titan of the cosmos is a staggering 2.3BN KM in diameter, and that is the least incredible of some of the numbers associated with it. Today, we will be analysing this star, and some of its close competition in the race for the largest star ever discovered. Want more videos?

People often ask: "how big is the biggest star?" But I reckon the more interesting question is how small are the smallest stars? Because when you get down to the smallest stars, there's a huge grey area between what is a star and what is a planet. Sub-brown dwarfs, planemos, rogue planets - how do we actually tell them apart?

April 25, 2019 Phillips Auditorium Sofia Ramstedt Uppsala U. Host: Rodolfo Montez Abstract: The deaths of stars are always preceded by more or less massive stellar winds. In the case of low- to intermediate mass stars, these winds are the means by which material from the stars is recycled in galaxies. Accurate measurements of the wind physical properties provide constraints for hydrodynamical models which study wind formation and evolution. Estimates of wind density and temperature also form the base for any further research into abundances of different elements, isotopes and molecules in the recycled material. Furthermore, to determine wind gas-to-dust mass ratios holds the key to investigations of extragalactic objects and the impact of these common stars across the Universe. We have lately performed detailed studies of the circumstellar envelopes (CSEs) around nearby (500 pc) stars on the Asymptotic Giant Branch (AGB) with ALMA. The properties of the wind which has created the CSE, can be derived by mapping the CO line emission. We started with a smaller sample of binary stars to investigate the formation and importance of circumstellar asymmetries and structure. To interpret the complex observations, several new analysis tools had to be assembled and tested. These tools are now put to use for the DEATHSTAR project in which we are mapping all nearby AGB stars starting in the southern sky. The goals are to provide the most accurate AGB wind properties to date, and to consistently determine the gas-to-dust mass ratios. I will present results and current status.

The smallest stars in the universe are Red Dwarfs. In fact, the smallest stars in the universe have just 7.5% the mass of the Sun. But Red Dwarfs are the longest-lived stars with lifespans stretching from 1 trillion to 12 trillion years. That means the oldest red dwarf star in the universe is just getting started, and the first red dwarf to ever form in the universe will still be around for trillions of years to come. But today's red dwarfs are violent stars, though they will slowly age and cool to become white dwarfs and then ultimately black dwarfs. When the last red dwarf dies, there will be no more stars shining in the universe. 🔔 Subscribe for more: https://www.youtube.com/christianready?sub_confirmation=1 🖖 Share this video with a fellow space traveler: https://youtu.be/bBaTtKWcsrA 🔴 Watch my most recent upload: https://goo.gl/QbRcE2 🚀 Help me improve the channel by joining the community on Patreon https://patreon.com/launchpadastro 🚀 Check out Launch Pad merchandise! https://teespring.com/stores/launchpadastro Disclaimer: Some of these links go to one of my websites and some are affiliate links where I'll earn a small commission if you make a purchase at no additional cost to you. 🐟 From out of town?

Had things gone a little differently during the formation of the solar system, could Jupiter have also become a star? Does that make it a failed star now?

Daniela Calzetti U.Mass, Amherst Understanding galaxy evolution requires understanding star formation and its dependence on the local environment, spanning the scales from individual stars to kiloparsec–size structures. The physical conditions within galaxies determine the formation of stars, star clusters, and larger structures, and their subsequent evolution. HST observations of external galaxies have enabled the characterization of the young stellar populations with unprecedented accuracy and detail, thus aiding the census and description of those populations. These observations are being used to quantify the spatial distribution and clustering of young stars, and investigate the impact and imprint of the physical conditions of both the local and global environment on the formation and evolution of the multi-scale structures. I will concentrate mainly on the results of the Legacy ExtraGalactic UV Survey (LEGUS), an HST Treasury programs that is investigating these issues using multi-color imaging, from the near-UV to the I, of a sample of nearby galaxies. I will also briefly introduce successor programs that promise to expand our understanding of star formation on galactic scales.

Visit our sponsor, Brilliant: https://brilliant.org/IsaacArthur/ Our current theory of evolution holds that all life on Earth originated from a single, simple life form billions of years ago. But what if that life did not originate on Earth? In this episode we'll explore the theory of Panspermia, that origin of life might be extraterrestrial in origin, and that the abiogenesis of that origin life form we descend from might have descended from the sky in a comet or some other alien source. We will explore the impact this concept would have on the Fermi Paradox if true.

The faint, ephemeral glow emanating from the planetary nebula ESO 577-24 persists for only a short time -- around 10,000 years, a blink of an eye in astronomical terms. ESO’s Very Large Telescope captured this shell of glowing ionised gas -- the last breath of the dying star whose simmering remains are visible at the heart of this image. As the gaseous shell of this planetary nebula expands and grows dimmer, it will slowly disappear from sight.

When a white dwarf in a binary star system acquires more material than it can handle it creates a violent outburst of surplus gas. With this outburst the white dwarf attempts to correct the imbalance. Channelled by the magnetic field of the star, the ejecta take the form of spectacular symmetric jets extending hundreds of billions of kilometres from the white dwarf’s polar regions.

This animation shows the artist’s impression of a vampiric star. The red giant in this system is slowly expelling its outer layers into space. Here the second star in the system, a white dwarf, is siphoning this material into a disc surrounding it. The material then spirals down from this disc onto the white dwarf. Occasionally, more material will fall onto the white dwarf than it can handle. When this occurs, a violent outburst of surplus gas from the white dwarf attempts to correct the imbalance. Channelled by the magnetic field of the star, the ejecta take the form of spectacular symmetric jets extending hundreds of billions of kilometres from the white dwarf’s polar regions.

Already in 1810 astronomers discovered that the brightness of the star R Aquarii periodically changes and it has subsequently been found to vary with a period of approximately a year. During these cycles, R Aquarii has been seen to fade into obscurity and then become so bright as to almost be visible to the naked eye. This animation is an artistic representation of this change in brightness. More information and download options: http://www.eso.org/public/videos/eso1840g/ Credit: ESO/M. Kornmesser

This zoom video starts with a wide view of the Milky Way and ends with a close-up look at the chaotic and fascinating binary star system R Aquarii. The image shown in this final image of this video is data from the SPHERE/ZIMPOL instrument on ESO’s Very Large Telescope (VLT), and shows the binary star itself, as well as the jets of material spewing from the interacting stellar couple.

This video shows the evolution of a chaotic and fascinating binary star system named R Aquarii. The time lapse begins with observations from the Nordic Optical Telescope taken in 1997. In the 15 years since that image was taken the system has been observed by many other telescopes, including ESO’s Very Large Telescope. This video lapses between a selection of these images, showing the expansion and evolution of the material surrounding R Aquarii. R Aquarii is a so-called “symbiotic binary”, comprising two stars surrounded by a large, dynamic cloud of gas (a nebula). Systems like this contain two stars in an unequal and complex relationship. R Aquarii is made up of one hot white dwarf and one red giant. The red giant is losing matter to its small companion and occasionally ejecting matter in weird spurts, loops and trails, forming the intriguing shapes seen here. There is a lot going on between the performers in this cosmic double act. The red giant is a variable star, with a brightness that changes by a factor of 750 every year and three weeks. The faint nebula is named Cederblad 211 and is thought to be the result of a violent nova 250 years ago. Also visible is a narrow, vertical, S-shaped feature, with blobs of superheated material.

While testing a new subsystem on the SPHERE planet-hunting instrument on ESO’s Very Large telescope, astronomers were able to capture dramatic details of the turbulent stellar relationship in the binary star R Aquarii with unprecedented clarity — even compared to observations from Hubble.

Thanks to the hardworking Gaia spacecraft, astronomers think they’ve located a star that formed from the same solar nebula as the Sun. In fact, this star is a virtual twin of the Sun and it’s actually pretty close. Well, astronomical speaking.

From their laboratories on a rocky planet dwarfed by the vastness of space, Clemson University scientist Marco Ajello and his team have managed to measure all of the starlight ever produced throughout the history of the observable universe.

A star system in our galaxy could give us a ringside seat for one of the brightest lightshows in the universe. And, with luck, it won’t wipe out all life on our planet. The system—located 8000 light-years away and dubbed Apep after an Egyptian snake deity—contains a binary pair of stars surrounded by a serpentine-shaped dust cloud. One of stars is an unusually massive sun known as a Wolf-Rayet star. When such stars run out of fuel, they collapse, causing a supernova explosion. https://www.sciencemag.org/news/2018/11/massive-star-system-primed-intense-explosion http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com
