- NASA's Hubble captures a crimson stellar nursery sparkling with blue and white stars
NASA's Hubble telescope captured an image of the stellar nursery LH 95, revealing 2,500 young stars still developing. Scientists found these stars can continue gathering gas and dust for millions of years, extending their developmental phase. The region contains multiple generations of stars, providing insights into star formation processes.
- Black hole winds may be robbing giant galaxies of their future stars
Astronomers using NASA- and JAXA-supported XRISM observations of galaxy NGC 4151 found evidence that supermassive black holes generate powerful winds that strip away star-forming material, potentially explaining why some massive galaxies have fewer stars than expected.
- Caltech’s Astronomy on Tap Hits 150th Show and 10th Year Tonight in Pasadena
Caltech’s free public-astronomy series 'Astronomy on Tap' is celebrating its 150th show and 10th anniversary at the Dog Haus Biergarten in Old Pasadena. Researchers will discuss star formation in the Milky Way and dark sky preservation, coinciding with Pasadena’s City of Astronomy events and the American Astronomical Society’s 248th meeting.
- Scientists just found the Milky Way’s edge and it’s closer than expected
Scientists discovered the Milky Way's edge using stellar 'age mapping,' revealing a U-shaped pattern where star formation declines sharply at 35,000–40,000 light-years from the center. Beyond this boundary, stars are primarily migrant stars drifting outward, not forming in place.
- Starbirth shuts down 40,000 light-years from the Milky Way's core — and astronomers don't know why
Star formation has ceased 40,000 light-years from the Milky Way's core, despite the galaxy's spiral disk spanning 100,000 light-years. Astronomers are uncertain why starbirth has stopped in this region.
