Our sun and a host of "solar twins" may have migrated away from the core of the Milky Way galaxy together long ago, potentially making the solar system more hospitable to life.

Researchers have uncovered evidence for our sun joining a mass migration of similar "twins" leaving the core regions of our galaxy, 4 to 6 billion years ago. The team created and studied an ...

ESA's Gaia mission, the Very Large Telescope and other ground-based telescopes have discovered stellar black hole Gaia BH3. It's mass is "33 times that of our Sun," according to the European Southern ...

The night sky appears perfectly still, but the universe is constantly changing in ways the human eye cannot see. By combining ...

A neutron star and black hole (GW200105) were detected merging along an unusual oval orbit, challenging theories about how ...

New high-resolution simulations reveal that stellar rotation plays a crucial role in transporting material inside red giant stars.

Astronomers have discovered a planet with a surface of molten magma and a sulfur-rich atmosphere, 34 light-years away in the constellation Volans. This planet is larger than Earth but less dense, ...

Over 4 billion years ago, as planets were coalescing around the newborn Sun, our star may have gone on an epic road trip across the Milky Way along with thousands of stellar "twins." And we may owe ...

Researchers from the University of Bologna and the Leibniz Institute for Astrophysics Potsdam (AIP) along with other institutes have proposed a new way to address the Hubble tension by comparing ...

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 ...

It's a new window into the first star explosions.

NASA astronomers using the Chandra X-ray Observatory have discovered a vast, million-degree gas bubble surrounding HD 61005, a 100-million-year-old Sun-like star about 120 light-years away. Its ...
