When three galaxies collide, what happens to the huge black holes at the centers of each? A new study using NASA's Chandra X-ray Observatory and several other telescopes reveals new information about how many black holes are furiously growing after these galactic smash ups. Astronomers want to learn more about galactic collisions because the subsequent mergers are a key way that galaxies and the giant black holes in their cores grow over cosmic time. There have been many studies of what happens to supermassive black holes when two galaxies merge, but this is one of the first to systematically look at what happens to black holes when three galaxies come together. Researchers identified triple galaxy merger systems by cross-matching the archives — containing data that is now publicly available — of NASA's WISE mission and the Sloan Digital Sky Survey, or SDSS, to the Chandra archive. By doing this, they found seven triple galaxy mergers located between 370 million and one billion light years from Earth. Using specialized software developed, the team went through Chandra data targeting these systems to detect X-ray sources marking the location of growing supermassive black holes. As material falls toward a black hole, it gets heated to millions of degrees and produces X-rays. Chandra, with its sharp X-ray vision, is ideal for detecting growing supermassive black holes in mergers. The associated X-ray sources are challenging to detect because they are usually close together in images and are often faint. The new software was developed specifically to find such sources. Data from other telescopes was then used to rule out other possible origins of the X-ray emission unrelated to supermassive black holes. The results show that out of seven triple galaxy mergers there is one with a single growing supermassive black hole, four with double growing supermassive black holes, and one that is a triple. These black holes are separated by a range between 10,000 and 30,000 light years. In the final triple merger, there was no evidence of X-ray emission. This means that none of the supermassive black holes left was rapidly pulling in matter. Astronomers will continue to use Chandra to learn more about what role mergers play in how galaxies and the giant black holes in their centers grow over cosmic time.

Thanks for joining us here at Space Videos. What has the moon in store for us this evening? We hope you enjoy the video - if you do, please like and share it. If you want to support us, why not buy us a virtual coffee - http://www.buymeacoffee.com/spacevideos In this short video we look at the moon, its current phase, illumination, distance from the Earth, as well as some of the features you will be able to see as they become visible tonight, especially when viewing with either a telescope or binoculars. With tonight's moon being 97% illuminated we get a great view of all the lunar seas and lakes, these great plains of solidified lava that cover so much of the moon's surface. On its western limb , the terminator (the line between darkness and light) allows us to get a peek at new craters including Pascal & Pythagoras in the North/North West Kraft, Cardanus, Hevelius, Riccioli and Grimaldi reveal themselves to the west and to the South/South West you have Bailly - the largest crater on the near side of the moon - some 303 Km in diameter! The moon of course can be enjoyed with the natural eye but even a small telescope will enhance the view and give you a better idea of its unique properties. Enjoy the night sky and if you are stargazing tonight we wish you clear skies! This video was created using data from Nasa's Scientific Visualization Studios.

Watch the Great Conjunction Webcast Live on Monday, December 21, 2020, starting at 4:30 p.m. On Monday, December 21, 2020, the Winter Solstice, planets Jupiter and Saturn will appear in the evening sky very close to each other, at about one-fifth of the Moon's diameter apart. This close approach of the two planets is called a "great conjunction" and occurs when the independent movements of Jupiter and Saturn make them appear close together in the sky. This happens once every 20 years, but they have not been seen this close together since 1226 A.D. If we have clear skies, this conjunction may be seen in the southwestern sky shortly after dark on December 21, and it should be visible from roughly 5:00 p.m. to 6:30 p.m. Jupiter and Saturn will be very close together. Anyone will be able to see the pair with unaided eyes. No telescope or binoculars is required, but a magnified view through a Griffith Observatory telescope will be live streamed. You can also observe both planets and their moons through your own telescope. LIVE WEBCAST: Griffith Observatory will start streaming the winter solstice great conjunction to our YouTube page on Monday, December 21, 2020, at 4:30 p.m., PST. The program will begin with a live view of the sunset, which occurs at 4:48 p.m., PST. A telescopic view of Jupiter and Saturn in conjunction will be streamed live as soon as acquired, in the twilight, perhaps by 5:00 p.m., PST.

December 21, 2020 marks the Winter Solstice and the Great Planetary Conjunction of Jupiter and Saturn. Learn what the solstice is and how to find Saturn and Jupiter in the sky tonight.

Join our December Solstice Star Party Live on early on the morning of Monday, December 21st, starting at 4:30 AM EST. Other timezones: 1:30 AM PST ¦ 09:30UTC ¦ 3 PM IST On December 21st, at 10:02UTC, the Sun appears at its most southerly point - marking the start of astronomical Winter in the Northern hemisphere. Join Slooh's experts and members to celebrate the precise moment of the December Solstice as we watch a live stream of the Sun using Slooh's special solar telescope located at its flagship observatory at the Institute of Astrophysics of the Canary Islands. The event will also be marked by the launch of a new Moments Quest where members can learn about the Solstice and create a superb infographic poster with the images they capture of the Sun as it passes over the Tropic of Capricorn!
