Ancient Stardust Points to Wolf-Rayet Winds Shaping Our Solar System

Presolar grains in meteorites—older than the Sun—are helping scientists test how our solar system formed. Evidence of aluminum-26 without iron-60 argues against a simple nearby supernova trigger and favors a scenario where winds from a Wolf-Rayet star delivered aluminum-26 into the nascent solar nebula; researchers are using nanoprobe analysis of meteorite grains to confirm this, though the origin story remains under debate.

"Stunning Discovery: 19 Wolf-Rayet Stars Found in Andromeda Galaxy"

Astronomers using the Lowell Discovery Telescope have discovered 19 new Wolf-Rayet stars in the Andromeda galaxy. These extremely hot and luminous stars are at an advanced stage of stellar evolution and are losing mass at a high rate. The newly detected stars are generally fainter than previously known ones due to increased reddening. The researchers estimate that there are about 60 more Wolf-Rayet stars left to be found in Andromeda and plan to focus on specific regions to identify more of these stars. The findings will contribute to a better understanding of the evolution and end states of massive stars.

JWST Observes Supernova Countdown from 15,000 Light Years Away

NASA's James Webb Space Telescope (JWST) captured a rare view of a Wolf-Rayet star, WR 124, which is about 30 times more massive than the Sun and has already shed enough material to make up ten Suns. The star is located roughly 15,000 lightyears away from us, in the constellation Sagitta. Observations like these give astronomers real data to work with for the first time, which could help them align their models more closely to reality and provide information about the stars lighting up the night sky today.
