Universe Today 1 Mar 2021, 18:43 UTC In May of 2019, the gravitational wave observatories LIGO and Virgo detected the merger of two black holes. One had a mass of 85 Suns, while the other was 66 solar masses. The event was named GW190521 and was the largest merger yet observed. It produced a 142 solar mass black hole, making it the first gravitational wave observation of an intermediate mass black hole. But the event also raised several questions.
Sky and Telescope 1 Mar 2021, 12:00 UTC As you’ll learn in this month’s Sky Tour podcast, this will be a month of transition in more ways than one. First, on March 14th, we jump to daylight time in virtually all of the U.S. and Canada (two weeks later in Europe, three in Mexico).
Universe Today 26 Feb 2021, 14:04 UTC Astronomers always like to look at incredibly violent places. Violence, in the astronomical sense, makes for rare conditions that can explain much about our universe. One of the violent places that astronomers love to study is the center of our Milky Way galaxy. Now, astronomers from the Center for Astrophysics (CfA) at Harvard have come up with a new catalogue of some of the most intense areas near the galactic core. They hope it will increase our understanding of these potential star-forming regions – and help explain why so few stars are actually formed in them.
ESO Blog 26 Feb 2021, 11:00 UTC We are all familiar with the awe we experience when looking up at the stars. For many people, this sense of wonder leads to inspiration. Astronomers look up and are inspired to know more about the weird and wonderful objects in the night sky, while artists and musicians, like Vera Matenaar from the Triagon Academy in Germany, are inspired to translate that wonder into a work of their own.
NASA Space Station Blog 25 Feb 2021, 20:50 UTC Two NASA astronauts are getting their tools and spacesuits ready for Sunday’s spacewalk to ready the International Space Station for new solar arrays. Meanwhile, the rest of the Expedition 64 crew focused on a variety of space research on Thursday.
Sky and Telescope 25 Feb 2021, 16:37 UTC Scientists may have discovered a clue to how massive stars form in the Orion Nebula and a stellar birthplace.
Universe Today 24 Feb 2021, 20:37 UTC Binary star systems are everywhere. They make up a huge percentage of all known solar systems: from what we can tell, about half of all Sun-like stars have a binary partner. But we haven’t really had a chance to study them in detail yet. That’s about to change. Using data from the European Space Agency’s Gaia spacecraft, a research team has just compiled a gigantic new catalog of nearby binary star systems, and it shows that at least 1.3 million of them exist within 3000 light-years of Eart
