Gravitational waves stretch and squeeze the fabric of space and time itself. When space/time is squeezed, pulsar pulses ...

"We would need to consider the possibility that the source was created (or trapped as a primordial black hole) by a highly ...

These black holes are the most distant and stable objects we know. Using a technique called very long baseline interferometry ...

The scientists who precisely measure the position of Earth are in a bit of trouble. Their measurements are essential for the ...

A supermassive black hole located 1.2 billion light-years away shows signs of intense activity. Observations reveal matter ...

A microquasar belonging to our Milky Way galaxy has set records by generating cosmic rays with energy levels never before ...

"Hulks can jump! I repeat, HULK CAN JUMP NOW!" writes one terrified, I mean valiant, Helldiver. Their video shows a Hulk ...

Caltech simulations reveal what happens when black holes collide with neutron stars—violent cracking, intense shock waves, ...

For decades, scientists have believed there should be black holes that fall between two well-known types. On one end are stellar-mass black holes, formed by collapsing stars, with masses between 5 and ...

This discovery challenges some ideas about how matter organizes around black holes. Contrary to what some models predicted, the detected emissions wouldn't come from a matter jet, but rather from ...

Black holes are invisible, yet they are among the brightest things in the universe. If a star wanders too close to a black hole, it gets torn apart in a fireworks show called a tidal disruption ...

Among the most studied black holes are those in the galaxy known as M87 and one at the center of our own. With this finer lens, researchers hope to uncover subtle details about their behavior.
