The Sun has been a powerful source of energy fueling the solar system for billions of years, but our host star may have had rough beginnings. A new study suggests the Sun migrated away from the center ...

In A Nutshell Scientists have identified 6,594 solar twins, stars nearly identical to our Sun, in the largest model-driven catalog of its kind ever assembled. Each star was assigned an estimated age, ...

Scientists believe this long stream of gas may have formed when several galaxies collided millions of years ago.

Despite years of debate and follow-up studies, an odd streak of cosmic light still defies a final explanation. Is it a giant ...

The Sun orbits in the thin disk of the Milky Way. It's located 27,000 light-years (8.3 kiloparsecs) from the Galactic Center, on the inner edge of the Orion spiral arm. It orbits around the galaxy ...

NASA has received the first images from a tiny spacecraft designed to study the stars that host distant planets. The mission, called the Star-Planet Activity Research CubeSat, or SPARCS, will track ...

The X-ray Imaging and Spectroscopy Mission (XRISM) spacecraft has delivered an "unprecedented tally of elemental sulfur ...

With the first images from the spacecraft now in hand, the team behind NASA's Star-Planet Activity Research CubeSat, or SPARCS, is ready to begin charting the energetic lives of the galaxy's most ...

The Gaia telescope spotted more than 6,000 sunlike stars, all of which appear to have migrated from the galaxy's center more ...

Most gamma-ray bursts—the brightest, most powerful explosions in the universe—are tracked back to the deaths of massive stars. But a new discovery suggests that such enormous explosions can come from ...

New SETI research suggests space weather like solar winds could be interfering with alien radio signals, making them harder ...
