A new study, led by a theoretical physicist at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab), suggests that never-before-observed particles called axions may be the source of unexplained, high-energy X-ray emissions surrounding a group of neutron stars.

The core mass of the giant exoplanet WASP-107b is much lower than what was thought necessary to build up the immense gas envelope surrounding giant planets like Jupiter and Saturn, astronomers at Universite de Montreal have found.

Computer simulations of cells evolving over tens of thousands of generations reveal why some organisms retain a disused switch mechanism that turns on under severe stress, changing some of their characteristics. Maintaining this "hidden" switch is one means for organisms to maintain a high degree of gene expression stability under normal conditions.

The Milky Way houses 8,292 recently discovered stellar streams - all named Theia. But Theia 456 is special.
A stellar stream is a rare linear pattern - rather than a cluster - of stars. After combining multiple datasets captured by the Gaia space telescope, a team of astrophysicists found that all of Theia 456's 468 stars were born at the same time and are traveling in the same direction a

ESA astronaut Matthias Maurer is preparing for his mission to the International Space Station, scheduled for launch in late 2021. This mission is known as Cosmic Kiss.
In this video log from his current training base at NASA’s Johnson Space Center in Houston, Texas, USA, Matthias shows a space food tasting session and shares how astronauts maintain their fitness for a safe return to Earth.

The U.S. Postal Service to issue NASA sun science forever stamps

NASA's images of the sun's dynamic and dazzling beauty have captivated the attention of millions. In 2021, the US Postal Service is showcasing the sun's many faces with a series of sun Science forever stamps that show images of solar activity captured by NASA's Solar Dynamics Observatory, or SDO.
"I have been a stamp collector all my life and I can't wait to see NASA science highlighted in this way," said Thomas Zurbuchen, associate administrator for NASA's Science Mission Directorate (SMD) in Washington. "I feel that the natural world around us is as beautiful as art, and it's inspiring to be able to share the import and excitement of studying the sun with people around the country.
