A group of US astronomers may have uncovered the first evidence for a dark matter sub-halo lurking just beyond our stellar neighborhood. Reporting their findings in Physical Review Letters, a team led by Sukanya Chakrabarti […]

A study led by the Center for Astrobiology (CAB), CSIC-INTA, using modeling techniques developed at the University of Oxford, has uncovered an unprecedented richness of small organic molecules in the deeply obscured nucleus of a […]

An international collaboration of astrophysicists that includes researchers from Yale has created and tested a detection system that uses gravitational waves to map out the locations of merging black holes—known as supermassive black hole binaries—around […]

A newly discovered comet has astronomers excited, with the potential to be a spectacular sight in early April. C/2026 A1 (MAPS) was spotted by a team of four amateur astronomers with a remotely operated telescope […]

Cosmic rays are extremely fast, charged particles that travel through space at nearly the speed of light. The Amaterasu particle was detected in 2021 by the Telescope Array experiment in the U.S. It is the […]

Our Milky Way galaxy may not have a supermassive black hole at its center but rather an enormous clump of mysterious dark matter exerting the same gravitational influence, astronomers say. They believe this invisible substance—which […]

A supermassive black hole with a case of cosmic indigestion has been burping out the remains of a shredded star for four years—and it’s still going strong, new research led by a University of Oregon […]

Aging stars can completely destroy their planets. When a star reaches the end of its life on the main sequence, it goes through dramatic changes. And those changes don’t just dictate the star’s fate; they […]

Quasi-periodic oscillations (QPOs) are a rare phenomenon in active galactic nuclei. They have been observed to occur at periods ranging from minutes to hours, days, weeks, and even years across the electromagnetic spectrum. A new […]

Astronomers have strengthened long-standing predictions that massive runaway stars could have originated in binary pairs, and were dramatically ejected into space when their companion stars underwent supernova explosions. Through a combination of observations and stellar […]
