Magnetic rivers feed star birth

Astronomers have learned that the pull of gravity can sometimes overcome the strong magnetic fields found in great star-forming clouds in space. The resulting weakly magnetized gas flow can feed the growth of new stars.

Truck-sized asteroid swept within 2,000 miles on Sunday

Asteroid ZTF0DxQ - now officially labeled 2020 QG - now holds the record for the closest flyby of Earth. It swept just 2,000 miles (3,000 km) from Earth's surface, or about a quarter of the diameter of Earth itself.

Mysterious dimming of Betelgeuse explained?

Observations with the Hubble Space Telescope revealed a large amount of dense hot gas moving outwards through Betelgeuse’s extended atmosphere. This gas might have cooled and formed a dust cloud that partially blocked the star's light as seen from Earth, earlier this year.

Ceres’ bright spots come from salty water below

The mysterious bright spots on Ceres caused a sensation when the Dawn spacecraft first spied them in 2015. Now, they're known to be salt deposits from a recent or ongoing percolation of briny water from a large reservoir in Ceres' interior.

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.
