An international team of astronomers led by Durham University and including astronomers at the UK Astronomy Technology Center has reported the first detection of a rotating disk structure around a ...

Cosmology seeks to describe the large-scale origin, content and fate of the Universe, while extragalactic astronomy extends these questions into the formation, evolution and interactions of galaxies ...

Solar extreme-ultraviolet (EUV) waves are large-scale disturbances that manifest as bright wavefronts, often during coronal mass ejections (CMEs). According to the magnetic field line stretching model ...

In a remarkable discovery, astronomers have found a disc around a young star in the Large Magellanic Cloud, a galaxy neighbouring ours. It’s the first time such a disc, identical to those forming ...

Positrons—the antimatter counterpart of electrons—are created in high-energy cosmic processes. When normal matter meets its antimatter counterpart, they annihilate, or vanish, and produce a ...

Scientists have discovered something mysterious in space. According to a new study shared on a preprint website, scientists have discovered an extragalactic structure inside an area of space known as ...

A team of researchers with members from Universidad Nacional de San Juan, Universidade Federal do Rio Grande do Sul and Universidad Andres Bello has found evidence of a large extragalactic assembly ...

Scientists have discovered a huge “extragalactic structure” hidden behind the Milky Way in a mysterious area of the sky known as the “zone of avoidance” because it is obscured by our own galaxy’s ...

The finding offers tantalizing clues in the ongoing quest to piece together the origins of ORCs—mysterious, ring-shaped radio signals from space. Reading time 2 minutes For lovers of cool astronomy ...

In a mysterious region of the sky known as the "zone of avoidance" veiled by our own galaxy's thick bulge, researchers have found a massive "extragalactic structure" hiding behind the Milky Way. As ...

The Committee on Astronomy and Astrophysics (CAA) provides an independent, authoritative forum for identifying and discussing issues in astronomy and astrophysics with the research community, the ...
