Astronomers found RR Lyrae stars at our Milky Way galaxy's core. They now believe ancient globular star clusters may have merged to form the core of the Milky Way.
These Tatooine worlds, as they're called, might be the ultimate survivors, as their 2 stars begin aging in ways that are sometimes threatening or even catastrophic.
Astronomers have found another possible rogue black hole, with about 100,000 times our sun's mass. It may have come from a small galaxy falling into a larger one.
Scientists analyzed sustainability projects around the world and identified overarching trends that can potentially help create a more sustainable future.
Deborah Byrd (asteroid 3505 Byrd) helps edit EarthSky.org and is a frequent host of EarthSky videos. Deborah created the EarthSky radio series in 1991 and founded EarthSky.org in 1994. Prior to that, she had worked for the University of Texas McDonald Observatory since 1976, and created and produced their Star Date radio series. She has won a galaxy of awards from the broadcasting and science communities, including having an asteroid named in her honor in 1990, a Public Service Award from the National Science Board in 2003, and the Education Prize from the American Astronomical Society in 2020. A science communicator and educator since 1976, Byrd believes in science as a force for good in the world and a vital tool for the 21st century. "Being an EarthSky editor is like hosting a big global party for cool nature-lovers," she says.
