For the first time, astronomers have used X-ray data to observe the sea of charged particles that radiates off a trio of bright stars. This outward flow, called stellar wind, plays a critical role in ...

An international research team led by a researcher from the University of Vienna has for the first time directly detected stellar winds from three Sun-like stars by recording the X-ray emission from ...

An extreme cosmic dance is unfolding in the binary system Cygnus X-1, 7,000 light-years away from us. There, a stellar black ...

A mysterious remnant from a rare type of supernova recorded in 1181 has been explained for the first time. Two white dwarf stars collided, creating a temporary 'guest star,' now labeled supernova (SN) ...

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 ...

Stellar astronomy and planetary systems form a cornerstone of astrophysical research, uniting our understanding of the life cycles of stars with the intricate architecture of the systems that form ...

New high-resolution observations with the VLT Interferometer of the European Southern Observatory in Chile reveal gas infall and outflow processes in the direct environment of six young stars. The ...
