Stellar winds were supposed to be the straightforward conveyor belt that carried the raw ingredients of life from dying stars ...

Stardust alone can’t drive stellar winds, reshaping what we know about how aging stars spread life’s elements through space.

New observations of the red giant star R Doradus suggest starlight alone cannot drive stellar winds that spread key elements through the galaxy.

Red giants are old stars that eject gaseous material and solid particles through a stellar wind. Some red giants appeared to lose an exceptionally large amount of mass this way. However, new ...

Each star system is a unique paintbrush in the cosmos, and astronomers are finally beginning to understand why. In new research, a team of scientists focused on a dozen cool red giant stars, the ...

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 ...

"Our estimated mass-loss rates can be used as a benchmark for stellar wind models and expand our limited observational evidence for the winds of sun-like stars." When you purchase through links on our ...

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 ...

A Canadian-led international team of astronomers recently discovered that spots on the surface of a supergiant star are driving huge spiral structures in its stellar wind. Their results are published ...

A red dwarf 130 light-years away has just rewritten the rules of space weather. For the first time, astronomers have captured definitive evidence of a massive coronal mass ejection from a star other ...
