NASA's oldest active astronaut, the 70-year-old Don Pettit, has returned home to Houston after a seven-month stint aboard the International Space Station.

The first 27 satellites of Amazon's Project Kuiper internet constellation are now scheduled to lift off atop an Atlas V rocket on April 28 from Florida.

Last week, scientists announced they found the "strongest evidence yet" of alien life beyond our solar system. However, the scientific community remains skeptical.

Where did the water we believe is on the Moon come from? Most scientists think they know the answer - from the solar wind. They believed the hydrogen atoms that make up the solar wind bombarded the lunar surface, which is made up primarily of silica. When that hydrogen hits the oxygen atoms in that silica, the oxygen is sometimes released and freed to bond with the incoming hydrogen, which in some cases creates water. But no one has ever attempted to replicate that process to prove its feasibility. A new paper by Li Hsia Yeo and their colleagues at NASA's Goddard Space Flight Center describes the first experimental evidence of that reaction.

A fleet of cubesats will act as a radio telescope to map the cosmic Dark Ages, its builders say.

Just how powerful is the world’s most powerful telescope?

This new teaser is packed with pregnancy, the power of family, plus the Silver Surfer.

Astronomers have observed a twinkling star and discovered an abundance of mysterious plasma structures in our cosmic neighborhood.

Scientists are still trying to understand the origin of multicellular life. It emerged about 1.2 billion years ago (or even earlier, according to some debated evidence). The timing of multicellular life's appearance on Earth is not the only thing being debated; so are the mechanisms behind it. New research supports the idea that multicellular life began when single-celled bacteria started grouping together.

A breathtaking new image of the famous Eagle Nebula captures a towering pillar of gas and dust sculpted by intense stellar radiation.

While it's much smaller than the largest supermassive black holes detected, it's still a whopper considering how early in the history of the universe it appeared.

NASA's Curiosity rover has found iron-rich carbonates on Mars — a major clue that the Red Planet used to be habitable.

The infant universe's population of huge black holes could owe itself to ultralight dark matter, scientists say.

SpaceX launched its 32nd cargo mission to the International Space Station today (April 21), sending more than 3 tons of supplies and scientific hardware to the orbiting lab for NASA.

A team of NASA scientists proposed a new initiative at the 56th Lunar and Planetary Science Conference (2025 LPSC). Known as the Commercial Hall Propulsion for Mars Payload Services (CHAMPS), the

SpaceX will launch an uncrewed Cargo Dragon to the International Space Station early Monday on a resupply mission with increased importance after a transportation mishap derailed a flight by another U.S. cargo ship. Liftoff from pad 39A at the Kennedy Space Center is scheduled for Monday, April 21, at 4:15 a.m. EDT (0815 UTC).
