Cosmic rays are one of the greatest challenges for space travel and pose a considerable risk to humans and materials. For the first time on European soil, an international research team in ...

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, ...

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 ...

A groundbreaking study in galactic archaeology proves the Sun made a treacherous journey to reach its current home in the Milky Way suburbs.

Astronomers have found that both the core of our Milky Way and the earliest proto-galaxies in the universe share a surprising ...

An international research team has found that the Milky Way and its galactic neighbors appear to sit inside a vast, flat concentration of dark matter, a structure stretching roughly 10 megaparsecs and ...

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 ...

Our sun was born 4.6 billion years ago near the crowded center of the Milky Way and then migrated roughly 10,000 light-years outward to the peaceful galactic suburbs it currently occupies. Now a pair ...

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 ...
