A NASA astronaut and the Russian cosmonauts parachute-landed in Kazakhstan on Wednesday after a trip back to Earth from the International Space Station, in a rare instance of U.S.-Russia cooperation.

These so-called exoplanets include rocky worlds similar in size to Earth, gas giants larger than Jupiter and even"'mini-Neptunes."

Building and operating telescopes can generate a lot of greenhouse gases. In fact, it's as if each astronomer in the world was driving more than 100,000 miles per year, a new study finds.

Wearing the colors Ukraine's flag has widely been seen as a way to support that country and oppose Russia's invasion.

NASA's Artemis 1 rocket, the Space Launch System, reached the Kennedy Space Center's Launch Complex 39B on Friday. The successor to the Apollo program could one day send humans back to the moon.

In 2016, Musk said that a "meaningful number of people" could reach the red planet in 10 years. Now, he seems to predict a crewed Mars landing in 2029.

Picture perfect: Mission managers say the telescope's mirror segments have been aligned and have focused on single stars, a critical milestone, and the telescope is working flawlessly.

Astronauts hammered collection tubes into the lunar surface on the last Apollo mission to the moon. Now a sample is being carefully pierced open — to be analyzed by today's latest tech.

Critics, including the National Park Service, said exploding rockets after launch could rain fiery debris onto surrounding land, including a federally protected wilderness.

A rocket part set to slam into the far side of the moon Friday morning highlights the growing issue of space junk in orbit around Earth, experts say

The mission, which had been set for this year, is a part of the ExoMars program to search for signs of life on Mars. It's likely to be delayed by nations' response to Russia's invasion of Ukraine.

Since touching down in Jezero Crater, NASA's Perseverance rover has already cached 6 samples that could one day be brought back to Earth. Astrobiologists hope they hold signs of past microbial life.

While you're sky-gazing, look to the western horizon. Jupiter will be setting there as evening twilight ends. And that bright star? That's Regulus, part of the Leo constellation.

Astronomers noticed it was unlikely the piece of space junk was from the Falcon 9 launch in 2015, due to the gap between the rocket's trajectory and object.

The James Webb Space Telescope has seen its first starlight, but its 18 mirror segments aren't yet perfectly aligned. As a result, the pictures it's sending back now aren't exactly cosmic eye candy.
