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

Analysis reveals what appears to be a channel of hot, low-density plasma stretching out from our solar system toward distant ...

Anastasios (Andy) Tzanidakis was combing through old telescope data from 2020 when he found an otherwise boring star acting very strangely. The star, named Gaia20ehk, was about 11,000 light-years from ...

Earth has been around for 4.543 billion years. At numerous times during that long history, our planet has shared itself with the rest of the Solar System, particularly with our immediate neighbors. Sc ...

Full report: 40 pages. Three pillars. One conclusion. The era of cost-per-watt is over. Solar Is Entering Its Density ...

Scientists are scrambling to explain why interstellar visitor 3I/ATLAS is carrying life's chemical building blocks at concentrations never before seen, and it makes its final pass through our cosmic n ...

NASA’s 1,323-pound Van Allen Probe A will re-enter Earth’s atmosphere soon. Most of the spacecraft will burn up, but some components may survive, with low risk to humans.

War Machine imagines a machine arriving from space. Real astronomy has detected interstellar visitors like ʻOumuamua, 2I/Borisov and 3I/ATLAS.

"Extremophile" bacteria could survive asteroid impacts that are strong enough to launch them into space, suggesting that life could travel between planetary bodies.

Global warming may be speeding up, with temperatures rising faster since 2015 and recent record-hot years reflecting a steeper climate trend.

Radio silence has long puzzled those searching for extraterrestrial intelligence, but the answer might lie much closer to the source of potential signals than previously thought. Conditions around ...

The NASA DART spacecraft shifted the orbits of two asteroids around the sun after intentionally crashing into one of them.
