Scientists say they're certain that a SpaceX rocket has slammed into the moon as predicted. While no one observed the actual impact, a telescope in Chile spotted what astronomers have identified as the debris plume resulting from the high-speed crash. The leftover rocket segment plowed into the moon Wednesday after drifting off course for the past year.

Astronomers have discovered a faint new world orbiting a young star after more than a decade of cosmic hide-and-seek.

A rocket belonging to Jeff Bezos' Blue Origin has exploded during a test at the launch pad. Thursday night's blast was felt in nearby Cape Canaveral and Cocoa Beach, Florida, and briefly turned the sky orange.

NASA has cleared its moon rocket for an April launch with four astronauts after completing the latest round of repairs. Mission managers made the call Thursday at Florida's Kennedy Space Center. NASA says the Space Launch System rocket will roll out of the hangar and back to the pad next week.

A cluster of space weather satellites has blasted off to cast fresh eyes on solar storms. The three satellites belonging to NASA and the National Oceanic and Atmospheric Administration soared from Florida on Wednesday morning on the same SpaceX rocket. They're aiming for a sun-orbiting lookout 1 million miles from Earth, each on its own separate mission.

The first astronauts in more than 40 years from India, Poland and Hungary have arrived at the International Space Station, ferried there by SpaceX on a private flight. The crew of four will spend two weeks at the orbiting lab, performing dozens of experiments. They launched Wednesday from NASA's Kennedy Space Center and arrived on Thursday.

A billionaire spacewalker is back on Earth. SpaceX's capsule carrying tech entrepreneur Jared Isaacman and his crew splashed down in the Gulf of Mexico near Florida's Dry Tortugas early Sunday.

NASA's newest climate satellite has blasted off to survey the world's oceans and atmosphere in unprecedented detail.

NASA is publicly addressing the subject of UFOs a year after launching a study into unexplained sightings. And it insists it's not hiding anything.

Jeff Bezos' rocket company has won a NASA contract to land astronauts on the moon, two years after losing out to SpaceX. Blue Origin received a $3.4 billion contract to develop a lunar lander.

The Webb Space Telescope has captured the rare and fleeting phase of a star on the cusp of death.

A rocket made almost entirely of 3D parts is on the launch pad in Florida awaiting its debut launch.
