The four participants of NASA's Crew-7 mission will now spend about six months living and working on the International Space Station.

NASA's Artemis moon rocket has finally launched after months of setbacks, from fuel leaks to hurricanes. If successful, the mission signals a big step toward returning humans to the moon.

The space agency has been trying for months to send its giant moon rocket on its first test flight. The goal is to send a crew capsule, with no astronauts on board, around the moon and back.

A total lunar eclipse happens when the moon falls completely in the Earth's shadow.

Early risers across the Northern Hemisphere will be able to see an eclipse Thursday morning when the moon passes between the Earth and the sun.

In Mercury Rising, historian Jeff Shesol recalls the early days of the U.S. space program, when Cold War fears ruled, and no one was sure Glenn would survive America's first orbital flight.

Jet Propulsion Laboratory project manager MiMi Aung gave an enthusiastic two thumbs-up and then clenched fists before a roomful of engineers erupted in applause.

An international crew of four is launching this week to the International Space Station from Kennedy Space Center. Once on station, they’ll conduct more than 200 experiments during their six-month stay.

A curious finding last year in the atmosphere of Venus has some scientists thinking one of our closest planetary neighbors could hold signs of life. A team of researchers found traces of phosphine gas using a ground based telescope in Hawaii. On Earth, this gas is created by the decaying of organic material which is considered a “biosignature” -- a material associated with the chemistry of life.

How do scientists locate planets outside our solar system? It’s not an easy feat, but astronomers and astrophysicists are using a variety of methods to understand other exoplanets and the possibility of life outside of our solar system.
