Astrobiologists say we could find evidence of microbial life within the next 10–20 years. What does that mean? Where are we ...

Only one of these patches of lunar plain can be Luna 9’s actual landing site – and there’s no guarantee that either of them is. But the search is oddly compelling.

Two research teams have identified possible landing sites for Luna 9, the first human-made object to safely reach the lunar ...

After Challenger, NASA explored a radical idea: keep the shuttle stack, remove the crewed orbiter, and create an uncrewed heavy-lift cargo vehicle. Shuttle-C promised massive payloads for the Moon and ...

Using data gathered by NASA's Juno Jupiter orbiter, scientists estimate that Europa's ice shell is about 18 miles thick — which could make it hard for nutrients to get down to its buried ocean.

At just 500 kilometers across, Saturn's sixth-largest moon would fit comfortably inside the United Kingdom, with room to spare.

Two rival teams — one using machine learning, the other human eyes — race to find the first spacecraft to soft-land on the moon.

Using high-resolution imagery from the Mars Reconnaissance Orbiter, the AI analyzed the bedrock and boulder fields. It processed the same data humans use, but it worked faster, stringing together ...

Discover the latest findings on interstellar comet 3I/ATLAS, from rare methane detections to high-resolution Hubble images, as it begins its final exit from our solar system.

Mars Global Localization (MGL), a tech similar to GPS on Earth, lets Perseverance nail down its coordinates to about 10 inches.

Astronomers are tracking a visitor called 3I/ATLAS, the third confirmed interstellar object ever observed. The two previous instances were 1I/’Oumuamua in 2017 and 2I/Borisov in 2019. 3I/ATLAS is ...

Former President Barack Obama ignited a firestorm when he seemed to admit aliens were “real.” Congress has explored the topic of UAP, UFOs for years.
