To ‘Infinity’ and beyond — a look at a newborn black hole

Yale University
Peer-Reviewed Publication

New Haven, Conn. — Yale astronomer Pieter van Dokkum and a team of researchers have discovered an object in space they call the “Infinity” galaxy — two recently-collided galaxies that, together, look like the symbol for infinity.

And at the center of “Infinity,” embedded in a cloud of gas, they say, is a supermassive black hole.

The findings are described in a new study to be published in The Astrophysical Journal Letters.

One survey by NASA’s Roman could unveil 100,000 cosmic explosions

NASA/Goddard Space Flight Center
Peer-Reviewed Publication

Scientists predict one of the major surveys by NASA’s upcoming Nancy Grace Roman Space Telescope may reveal around 100,000 celestial blasts, ranging from exploding stars to feeding black holes. Roman may even find evidence of some of the universe’s first stars, which are thought to completely self-destruct without leaving any remnant behind.
