An international team of astronomers, including researchers from the Department of Physics and the Hong Kong Institute for Astronomy and Astrophysics (HKIAA) at The University of Hong Kong (HKU), has discovered a previously hidden phase […]

In the early days of the universe, our home looked very different from how it does today. Back then, the region in our universe that would eventually become our Milky Way neighborhood was a collection […]

Astronomers analyzed 2,435 galaxies hosting actively feeding black holes using data from the Dark Energy Spectroscopic Instrument (DESI). Among them, they identified 546 “bulgeless” galaxies—systems with little or no central stellar bulge. Their paper, published […]

Astronomers using Georgia State University’s Center for High Angular Resolution Astronomy (CHARA) Array have found that nearby stars darken toward their edges more strongly at near-infrared wavelengths than predicted by several widely used models of […]

Neutron stars, the extremely dense remains of massive stars that exploded at the end of their lives, are widely studied astrophysical objects. Some of these stars, known as pulsars, spin and send out beams of […]

Researchers from The Australian National University (ANU) have engineered new optical coatings for LIGO, the global collaboration hunting gravitational waves from colliding black holes and neutron stars.This post was originally published on this site

The center of the Milky Way galaxy is a chaotic place. In addition to the 4-million-solar-mass black hole known as Sagittarius A* (Sgr A*), the region is full of gas, dust, strong magnetic fields and […]

Cosmic detectives are being called on for an interstellar mission to hunt down thousands of invisible black holes lurking in our own backyard. Space scientists from the University of Southampton need amateur astronomers to search […]

A team of researchers led by the National Astronomical Observatory of Japan discovered unexpectedly intricate magnetic structures above quiet-sun regions by observing the sun with the balloon-borne solar observatory Sunrise-III during its 2024 flight in […]

For decades, astronomers have identified collisions between two neutron stars through bursts of gamma rays that can disappear in less than two seconds. But some of these violent encounters may also reveal themselves through X-ray […]
