‘Missing link’ black hole discovered by astronomers

by Reuters, New York Post

Scientists have detected a mid-size black hole – considered the “missing link” in the understanding of these celestial brutes – eviscerating an unfortunate star that strayed too close.

Using data from the Hubble Space Telescope and two X-ray observatories, the researchers determined that this black hole is more than 50,000 times the mass of our sun and located 740 million light years from Earth in a dwarf galaxy, one containing far fewer stars than our Milky Way.

Infinite Visions Were Hiding in the First Black Hole Image’s Rings

by Dennis Overbye, The New York Times

Scientists proposed a technique that would allow us to see more of the unseeable.

A year ago a team of radio astronomers startled the world with the first photograph of a black hole, lurking like the eye of Sauron in the heart of a distant galaxy. Now it appears there was more hiding in that image than we had imagined.

Scientists Just Found an “Impossible” Black Hole in The Milky Way Galaxy

by Michelle Starr, ScienceAlert

A new black hole search method has just yielded fruit, and boy is it juicy. Astronomers have found a stellar-mass black hole clocking in at around 70 times the mass of the Sun – but according to current models of stellar evolution, its size is impossible, at least in the Milky Way.

Planets around a black hole? Calculations show possibility of bizarre worlds

by Hitoshi Yamaoka, National Astronomical Observatory of Japan, Phys.org

Theoreticians in two fields defied the received wisdom that planets only orbit stars like the sun. They proposed the possibility of thousands of planets around a supermassive black hole.

‘Planet Nine’ may actually be a black hole

by Sid Perkins, Science Magazine

For nearly 5 years, growing numbers of scientists have blamed the weird orbits of distant solar system objects on the gravitational effects of an as-yet-undiscovered “Planet Nine” that lies in the icy realm far beyond Neptune. But a pair of physicists is now floating an intriguing idea that could offer a new way to search for the object: What if that supposed planet is actually a small black hole?
