Primordial black holes (PBHs) don’t exist as far as we know. But if they did, these hypothetical objects would have formed in the early universe rather than from dying stars, and they may even make […]

Heat shields are one of the most important parts of any spacecraft that intends to enter an atmosphere. And the material they are made of is critical. Improving them has been a challenge, though, as […]

Astronomers have discovered the first example of a second-generation planet orbiting a white dwarf, a world that appears to have formed from the remains of the dead star it now orbits.This post was originally published […]

Dark matter could be a type of matter in the universe that does not emit, absorb or reflect detectable light and appears to interact very weakly with regular matter. Although physicists have observed gravitational effects […]

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
