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 ...

"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 ...

John Sadler could have done what many other trainers did a week ahead of the Breeders' Cup—move Stellar Wind 's scheduled workout up a day because of looming storms in Southern California. But more ...

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 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 ...

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 ...

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

Interactions with binary companions shape the stellar winds blowing from elderly stars, generating the dazzling array of complex shapes found in the planetary nebulae they produce, a new study finds.

DEL MAR, Calif. (AP) Stellar Wind won the $100,000 Torrey Pines Stakes for 3-year-old fillies by 4 1/4 lengths Sunday at Del Mar. Ridden by Victor Espinoza, Stellar Wind ran a mile in 1:36.43 and paid ...

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 ...
