Scientists find the largest observed black hole to date
Astronomers aren't done with major black hole discoveries this year. The Max Planck Institute's Kianusch Mehrgan and colleagues have found the largest black hole ever observed at the center of Holm 15A, a galaxy about 700 million light-years away. It's more than twice as large as the previous observed record-setter at 40 billion times the mass of the Sun, and 10,000 times the mass of the black hole at the core of the Milky Way.
Russia launches X-ray telescope to find 'millions' of black holes
Russia is back in the business of space observation after losing control of a radio telescope a the start of 2019. The country has successfully launched Spektr-RG, an X-ray telescope co-developed with Germany's help. The vessel will take 100 days to reach its final destination of Lagrange Point 2, where it can conduct studies in stable conditions a million miles from Earth. When it gets there, though, it could significantly reshape human understanding of the universe.
Scientists think some supermassive black holes didn’t start as stars
Despite the fact that scientists now have a real image of a supermassive black hole, they still have plenty of questions about the objects. Now, astrophysicists at Western University may have a new explanation for how some black holes formed. In research published in The Astrophysical Journal Letters today, Shantanu Basu and Arpan Das suggest that not all black holes emerge from star remnants. Their model may help scientists explain the formation of extremely massive black holes at a very early stage of the universe's development.
This is the first real picture of a black hole
Yes, it happened. After years of relying on computer-generated imagery, scientists using the Event Horizon Telescope have captured the first real image of a black hole. The snapshot of the supermassive black hole in the Messier 87 galaxy (about 55 million light years away) shows the "shadow" created as the event horizon bends and sucks in light. It also confirms that the black hole is truly huge, with a mass 6.5 billion times that of the Sun. As you might imagine, taking this picture was tricky -- it required worldwide collaboration that wasn't possible until recently.
