A team of scientists is proposing a bold alternative to the Big Bang theory, suggesting that our universe may have instead formed inside a colossal black hole.
Using the XMM-Newton telescope, astronomers have witnessed high-speed "burps" erupting from a distant overfeeding supermassive black hole.
Researchers used an AI model to create a new image of the black hole at the center of the Milky Way, with some concern from experts.
A powerful new technique is poised to revolutionize how astronomers observe black holes, by producing sharp, multicolored images that could reveal their dynamic evolution in real time.
Supermassive black holes that seem too large to exist in the early universe may have grown from primordial black holes formed in the first second after the Big Bang.
A mystery signal detected high in the sky above Antarctica defies current models of physics and could represent a new particle, scientists say.
"It's like looking for candlelight in close vicinity to a flashlight that's blazing toward us."
A neutron star's final moments may spark violent starquakes, monster shock waves, and even a fleeting, never-before-seen object called a black hole pulsar.
Scientists have made the most accurate predictions yet of the gravitational waves produced when two black holes fly past each other.
Every time this doomed star plunges through a supermassive black hole's accretion disk, it loses orbital energy and triggers a burst of X-rays.
