An exploration of the Kardashev scale and Dyson spheres. It’s possible that in a few centuries Humans may be able to capture all the energy on Earth, in a few thousand years we might be able to capture all the energy from the Sun, and we might be able to harvest all the energy from every star in our galaxy in 100,000 to one million years. In this video, we discuss the Kardashev scale and look in detail on each civilization type, as well as discussing Dyson spheres. ►Click here to subscribe: https://www.youtube.com/channel/UCB0fFWQLZ2oj-FaoDUG_wow?sub_confirmation=1 ►Written, Produced & Narrated by: David ►Share this video: https://youtu.be/D2GGI3u_RRg Music: “So Many Stars” by Miguel Johnson “A Memory of Earth” by Markus Junnikkala “Staring Through” by AJ Prasad

ESA's XMM-Newton has spotted surprising changes in the powerful streams of gas from two massive stars in the binary star system HD 5980. One of the two stars had a major outburst reminiscent of the 19th-century eruption of Eta Carinae, and astronomers expected that its X-ray emission would fade gently over the years. Instead, they found the pair was two and a half times brighter than a decade earlier, and its X-ray emission was even more energetic, suggesting that colliding stellar winds don’t behave as expected.

This zoom sequence starts with a view of the central parts of the Milky Way. We close in on a region in the constellation of Scorpius (The Scorpion). The final view is a combined image from data from both the VLT Survey Telescope and the MPG/ESO 2.2-metre telescope at the La Silla Observatory in Chile. It shows a dark cloud where new stars are forming along with a cluster of brilliant stars that have already burst out of their dusty stellar nursery. This cloud is known as Lupus 3 and it lies about 600 light-years from Earth. It is likely that the Sun formed in a similar star formation region more than four billion years ago.

What types of stars are most likely to have planets that harbor complex life? Astronomers (and everyone else for that matter) are very interested in finding out if there is life in the universe besides our own. One area of inquiry has been about the stars themselves: what types of stars might be most likely to have life in orbit around them. This hangout delves into this topic with Drs. Manfred Cuntz and Ed Quinan whose paper makes the case for the best type of star being a k dwarf star. Please join Tony Darnell, Dr. Jeffrey Kuhn and Dr. Svetlana Berdughina to discuss this and much more on the question of life in the universe.

These models are largely built around what little we can learn from the light we receive directly from the surface of stars. But how do we test these models if we can never see beneath those surfaces? We may not see light from beneath the stellar surface, but another type of wave travels freely throughout stars.

In this 1961 edition of the Sky at Night Patrick Moore talks about star clusters

A star some 550 million light-years from Earth might be destroying its exoplanets, creating clouds of gas and dust that cause the star to dim erratically.

A new project using data from NASA's Chandra X-ray Observatory and other telescopes allows people to navigate through real data of the remains of an exploded star for the first time. This three-dimensional virtual reality (VR) project with augmented reality (AR) allows users to explore inside the debris from actual observations of the supernova remnant called Cassiopeia A. Cassiopeia A (Cas A, for short) is the debris field of a massive star that blew itself apart over 340 years ago. The new 3D VR/AR project of Cas A is a collaboration between the Chandra X-ray Center in Cambridge, Mass., and Brown University's Center for Computation and Visualization in Providence, RI, and will provide new opportunities for public communications, informal education, and research. "The stars are much too far away to touch, but this project will let experts and non-experts — at least virtually — walk among one of the most famous supernova remnants in our sky," said Kimberly Arcand, Visualization Lead at the Chandra X-ray Center. VR is computer technology that simulates a user's physical presence in a virtual environment. AR adds elements, such as text, overlays and audio, to enhance that experience with sensory input. Chandra has repeatedly observed Cas A since the telescope was launched into space in 1999. Each exposure has added new and important data to the growing bank of information that astronomers use to study this object. This deep reservoir of data has allowed astronomers and visualization specialists to take the Cas A far beyond the two-dimensional imagery that exists for most astronomical objects. In 2009, a team of scientists, including astrophysicist Tracy Delaney (then of the Massachusetts Institute of Technology) and visualization experts used data from Chandra, NASA's Spitzer Space Telescope, and ground-based optical facilities to generate a three-dimensional (3D) digital model of Cas A, the first ever of a supernova remnant. In 2013, a team of data specialists translated that into the first 3D print of a supernova remnant. "As technology has advanced in the VR and AR realms in recent years, we realized that we could go further with the 3D Cas A model," said Arcand. "Instead of us telling people where to look in Cas A, this project lets them decide for themselves." "The visualization of the Cas A supernova remnant took years to put together, and it deserves a magnificent way to experience it," said Tom Sgouros of Brown's Virtual Reality Lab. "Short of creating a building-size replica of the data, we think virtual reality is the best way to do that." The 3D visualization and VR/AR may also pay scientific dividends as well. It shows that there are two main components to this supernova remnant: a spherical component in the outer parts of the remnant and a flattened (disk-like) component in the inner region. The insight into the structure of Cas A gained from the 3D visualization is important for astronomers who build models of supernova explosions. The VR project is being made available in an open access format suitable for VR caves or "Yurts," as well as on the Oculus Rift platform. Please contact Kimberly Kowal Arcand (kkowal "at" cfa.harvard.edu) for more information on accessing those files. The project coordinators plan for a Google Cardboard version in future iterations. Additional data-driven 3D astronomical objects are also in the works for the Chandra VR/AR experience. More information on Cas A in VR is available at http://chandra.si.edu/vr. For access to non-VR versions, the Smithsonian Learning Lab has created an interactive 3D application for the 3D Cas A with related resources and activities. Visit http://s.si.edu/cas-a

Astronomers using ESO’s Very Large Telescope have for the first time directly observed granulation patterns on the surface of a star outside the Solar System — the ageing red giant π1 Gruis. A remarkable image from the PIONIER instrument reveals the convective cells that make up the surface of this huge star, which is 350 times larger than the Sun. Each cell covers more than a quarter of the star’s diameter and measures about 120 million kilometres across. The video is available in 4K UHD.

Dark matter is the mysterious and pervasive substance that constitutes most — about 85% — of the matter in our Universe. Although scientists have made progress in better understanding dark matter, the true nature of this invisible material remains elusive. NASA's Chandra X-ray Observatory plays an important role in the search to learn about dark matter. One way that astronomers have used Chandra to investigate dark matter has been through the study of a mysterious signal seen in the X-ray data. In 2014, astronomers reported they found a spike of intensity at a very specific energy in Chandra and XMM-Newton observations of the hot gas in the Perseus and other galaxy clusters. This spike, or emission line, is at an energy of 3.5 kiloelectron volts, or keV (pronounced "kay-ee-vee"), and could not easily be explained as emission from known elements. Therefore, one possibility was that this line was produced by dark matter particles. Naturally, determining the true nature of dark matter would be a huge discovery. And as Carl Sagan famously said, extraordinary claims require extraordinary evidence. Therefore, astronomers have been working hard both to replicate the initial results and also provide explanations for all of the observations connected to this original finding. Now a new team of astronomers has provided an innovative interpretation of the observations surrounding this 3.5 keV line. They propose that there is another mechanism at work, namely the absorption of X-ray light by mystery particles. If this is true, then it's possible that the 3.5 keV line may, in fact, be produced by dark matter particles. While these ideas need to be confirmed with future observations, it may be that the prospect of determining the nature of the darkest of matter may never have been more so bright.

Kimberly Arcand, CfA, Visualization Lead for NASA's Chandra X-Ray Observatory; Tom Sgouros, Manager of the Brown University Virtual Reality Lab Objects in space are rather far away. The Moon is our closest celestial neighbor at nearly a quarter million miles from Earth, and the nearest star, our Sun, is 93 million miles away. These extreme distances mean that it’s usually impossible to touch real objects in space (meteorites that fall to the ground notwithstanding). But now, thanks to data from some of our favorite observatories, anyone can hold a dead star in their hand. Here’s how. Arcand, of the Chandra X-Ray Observatory, will talk about the process of creating the first data-based 3D model and print of an exploded star. At the end of Arcand's talk, she will be joined by Tom Sgouros, a researcher with and on virtual reality at the Brown University Center for Computation and Visualization. Arcand and Sgouros have worked together to develop software, using Occulus Rift technology, allowing observers virtual first-hand experience of a supernova remnant like never before.

It's the perfect meeting of old and new. Astronomers have combined recent data from ESA's Gaia mission with a simple analysis technique from the 18th century to discover a massive star cluster that had previously escaped detection. Subsequent investigations are helping to reveal the star-forming history of our Galaxy, the Milky Way. For more about this story see How do you find a star cluster?

This animation shows the location of the galaxy M82 on the sky (off the bowl of the Big Dipper), then zooms in to show the location of the supernova SN 2014J. After that, it shows animated Hubble images of a "light echo", the flash of light from the supernova lighting up dust clouds all around it. We see this as an expanding circle from the explosion.

Astronomers are puzzled by the discovery of a star that "would not die."

Did you know that some of the stars we see in the sky may already be dead! Their light travels millions and millions of kilometres, and by the time it reaches us, the star would have died. So the distance between our planet and the stars further away, is unimaginable, but measurable still. Watch and learn how these distances can be measured and the secrets hiding among the stars.

The mystery of the "alien megastructure" star may finally be settled. In 2015, a rumor spread about the star KIC 8462852. It was proposed that the star might harbor an alien race. The rumor stemmed from the star's unusually unstable brightness. One explanation for the behavior was an alien megastructure called a "Dyson swarm." Now, that possibility has been ruled out. So, what's actually going on? To find out, scientists used telescopes in space and on the ground. They observed the star in wavelengths invisible to the human eye. What they saw couldn't be explained by a Dyson swarm. When the star dimmed, it dimmed more in the ultraviolet than in the infrared. This wouldn't be possible with a Dyson swarm because the Dyson swarm would block all light equally. Instead, it's likely a cloud of dust orbiting the star every 700 days. This would explain the long-term dimming of the star over years. But there's still more research needed. There's also short-term, daily dimmings from this star. The scientists aren't sure yet if a dust cloud can explain both. Either way, we can now say with more certainty than ever. It's not aliens.

The Milky Way galaxy was once ablaze with bright young stars. Today, star formation has calmed down, but we glimpse intense pockets of gas that are forming massive stars, testifying to the brilliant past. Stars form in clouds of interstellar gas that orbit their host galaxy. The clouds acquire more mass as gas accumulates, and the gaseous nebulae are soon massive enough to become unstable, due to the pull of their own gravity. As the clouds collapse, their central regions fragment into dense clumps of cold gas that eventually form stars. Dust particles are the key ingredients that eventually coalesce to form a disk-like structure with rocky cores that orbit the forming sun and agglomerate into planets. The entire solar system was formed out of interstellar grit.

September 28, 2017 Phillips Auditorium Kaitlin Kratter Univ. of Arizona Host: Alyssa Goodman Abstract: In the past 5 years, new observational facilities have provided remarkable data sets against which we can evaluate theories of star formation and planet formation. I will describe three different theoretical investigations motivated or corroborated by new observations. In each case, important open questions remain. First I will discuss the formation of close binaries through a variety of channels. I will illustrate how ALMA and careful statistical studies have begun to validate a long-held theoretical picture. Next, I will discuss the surprising high resolution ALMA images of protoplanetary disk asymmetries. I will show how careful numerical models can validate (or not) the interpretation of these images as evidence for the Rossby Wave Instability. Finally, I will discuss the dynamics of the Pluto-Charon circumbinary satellite system. The New Horizons space mission not only provides new insights into the formation of these bodies, but also provides a record of the Kuiper Belt and thus planet formation in the outer solar system.

Recent observations confirm a nova seen 600 years ago. The diligence of experienced star gazers can stand the test of time, in this case 600 years later. Korean astrologers in Seoul almost 600 years ago observed a bright new star in the tail of the constellation Scorpius. They monitored it for 15 days, but then it faded from view. A new look by astronomers today considered the observations of the Royal Imperial Astrologers. They determined this transient star was an outburst called a nova explosion. A recently published study discusses the new data that suggests that observation from the 1930s signaled the presence of a small scale “dwarf nova” which undergoes periodic eruptions. This means that some of these objects can erupt and then fade for hundreds even thousands of years before being seen again. Join Tony Darnell and Carol Christian during Afternoon Astronomy Coffee on September 28, 2017 at 3PM Eastern (Daylight) Time as they discuss with Michael Shara (American Museum of Natural History) and collaborators how this object was found and what the new analysis indicates about it.

Astronomers have used ALMA to capture a strikingly beautiful view of a delicate bubble of expelled material around the exotic red star U Antliae. These observations will help astronomers to better understand how stars evolve during the later stages of their life-cycles. This short podcast takes a look at this important new result and what it means. The video is available in 4K UHD.

This illustration shows a cool star, called W1906+40, marked by a raging storm near one of its poles. The storm is thought to be similar to the Great Red Spot on Jupiter. Scientists discovered it using NASA's Kepler and Spitzer space telescopes. The location of the storm is estimated to be near the north pole of the star based on computer models of the data. The telescopes cannot see the storm itself, but learned of its presence after observing how the star's light changes over time. The storm travels around with the star, making a full lap about every 9 hours. When it passes into a telescope's field of view, it causes light of particular infrared and visible wavelengths to dip in brightness. The storm has persisted for at least two years. Astronomers aren't sure why it has lasted so long. While planets are known to have cloudy storms, this is the best evidence yet for a star with the same type of storm. The star, W1906+40, belongs to a thermally cool class of objects called L-dwarfs. Some L-dwarfs are considered stars because they fuse atoms and generate light, as our sun does, while others, called brown dwarfs, are known as "failed stars" for their lack of atomic fusion. The L-dwarf W1906+40 is thought to be a star based on estimates of its age (the older the L-dwarf, the more likely it is a star). Its temperature is about 2,200 Kelvin (3,500 degrees Fahrenheit). That may sound scorching hot, but as far as stars go, it is relatively cool. Cool enough, in fact, for clouds to form in its atmosphere. W1906+40 is located 53 light-years away in the constellation Lyra.
