Scientists Claim That Gravitational Waves Could Retrace the Origins of Black Holes in Dense Stars Black holes have always ...

By observing tiny ripples in spacetime called "gravitational waves" that propagate away from colliding black holes, ...

Hypervelocity stars (HVSs) were first theorized to exist in the late 1980s. In 2005, the first discoveries were confirmed.

Astronomers looked more closely at one of seven stars that looked like possible Dyson sphere candidates from earlier observations.

By revealing a massive radio jet in the early universe, J1601+3102 offers a rare snapshot of early quasar activity.

The Hubble Space Telescope has imaged a "200,000 light-year-long trail of newborn stars" that may have been left behind by a ...

Astronomers theorize that a low-mass white dwarf, a compact core of a dead star about as large as Earth, could be the culprit. A cosmic mystery surrounding a black hole some 270 million light ...

Researchers said on Thursday that they had discovered twin-lobed radio jets they suspect were formed when the universe was ...

"Interestingly, the quasar powering this massive radio jet does not have an extreme black hole mass compared to other quasars ...

But it likely won't fall in. 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. Credit: Aurore Simonnet / Sonoma ...

Rather than relying on a cheek swab or a little blood, however, these cosmic DNA tests utilize tiny ripples in the fabric of ...

Now, though, NASA has actually watched a black hole eat a star. To get a good view of the event, NASA used multiple of its space telescopes to observe the black hole as it ate the star.
