A new study reveals Earth's magnetic flips can last up to 70,000 years, exposing life to increased solar radiation.

We all know that stars radiate light and much more. But radiation belts can also surround many other celestial bodies, such ...

Earth’s magnetic field acts as a protective shield, deflecting dangerous solar radiation and helping make life possible on ...

The magnetic barrier that protects Earthlings from radiation almost collapsed some 565 million years ago. Here’s what saved ...

Some of the most extreme explosions in the universe are Type I superluminous supernovae. “They are one of the brightest ...

A spacecraft plunged back into Earth’s atmosphere early Wednesday. While most of the probe was expected to burn up during ...

A 1,300-pound NASA probe re-entered Earth's atmosphere on Wednesday, nearly 14 years after it was launched. The U.S. Space Force confirmed the Van Allen Probe A, which was launched in August 2012, ...

A 1,300-pound NASA satellite is expected to crash through Earth's atmosphere March 10, 2026, with some of the spacecraft ...

A fungus that evolved at Chernobyl and is now grown on the ISS, Cladosporium sphaerospermum, slightly reduced radiation levels.

Mars didn’t always look like the barren world we see today. Over billions of years, the Sun’s solar wind stripped away much of its atmosphere, helping transform it from a warmer, wetter planet into a ...

A new study explains how some supernovae are particularly dazzling—the glow from a magnetic, spinning ball of neutrons called a magnetar. An assist from Einstein is what settled the case ...
