Stellar astronomy examines the life cycles of stars from their birth in dense molecular clouds to their ultimate fates as white dwarfs, neutron stars or black holes. Turbulence and gravity sculpt ...

3D simulations reveal how shockwaves from stellar explosions and winds may carve hub-and-spoke structures in molecular clouds ...

Astronomers using NASA’s Chandra X-ray Observatory have clocked the fastest wind yet discovered blowing off a disk around a stellar-mass black hole. This result has important implications for ...

Astronomers have confirmed the existence of a companion star in a tight orbit around Betelgeuse, resolving a long-standing mystery about the star’s varying brightness. A 600-year-old stellar event ...

Astrometric data analysis underpins our understanding of stellar positions, distances and motions, enabling a three-dimensional map of the Galaxy and a dynamical portrait of its constituent stars. At ...

They’re bright and blue — and a bit strange. They’re a new type of stellar explosion that was recently discovered by a team of astronomers led by the California Institute of Technology (Caltech).

Astronomers present an explanation for the mesmerising shapes of planetary nebulae. The discovery is based on an extraordinary set of observations of stellar winds around ageing stars. Contrary to ...

A breakthrough discovery by an international team of astronomers has brought scientists closer to solving one of the most intriguing mysteries in modern astrophysics. Researchers have identified the ...

A bright ring of dust circling a young star can look calm from far away. In reality, it may mark one of the messiest moments in planetary birth, where gas, pebbles, and gravity are still fighting over ...

Zooming in on 78 disks in the Ophiuchus star-forming region, scientists saw hitherto undiscovered structures around young stars. When you purchase through links on our site, we may earn an affiliate ...
