A supermassive black hole in a distant galaxy is once again surprising scientists. In 2018, a black hole called 1ES 1927+654, located about 270 million light-years away from Earth, showed its ...

It once was home to a dwarf elephant relative, giant rats and a giant stork, as well as a dwarf human species - Homo floresiensis, nicknamed the "Hobbit," standing just 3-1/2 feet tall (106 cm) tall.

Of three possible explanations, one is a white dwarf star caught in the black hole’s gravity. Scientists will monitor the phenomenon to find out for sure, and 2035’s LISA antenna will verify.

Teams of astronomers at Meyer's university and many other institutions have been keeping an eye on the black hole ever since. The vigilance paid off when, in April 2023, a team at the university ...

In 2018, a distant black hole threw a fit. The 1.4-million-solar-mass black hole at the center of the galaxy 1ES 1927+654 some 270 million light-years away suddenly began spewing radiation ...

The explosion of a star, called a supernova, is an immensely violent event. It usually involves a star more than eight times ...

Eventually—over tens or even hundreds of billions of years—a white dwarf cools until it becomes a black dwarf, which emits no energy. Because the universe's oldest stars are only 10 billion to ...

Astronomers found a black hole acting unusually in 2018. ... An artist's rendering of a white dwarf star speeding around the black hole 1ES 1927+654. A stream of particles trails the dense star.

The black hole in question is 1ES 1927+654, located around 270 million light-years from Earth, with a mass around 1.4 billion times that of the sun. 1ES 1927+654 first announced its weirdness to ...

The team also determined the masses of the black holes in more than 4,000 galaxies, dwarf and not. Then it searched for intermediate-mass black holes , with masses between about 100 and a million ...
