NASA's James Webb Space Telescope has successfully deployed its giant primary mirror, putting the new observatory one big step closer to being ready for launch in 2021.
Meteors, also known as shooting stars, are pieces of dust and debris from space that burn up in Earth's atmosphere, where they can create bright streaks across the night sky. When Earth passes through the dusty trail of a comet or asteroid's orbit, the many streaks of light in the sky are known as a meteor shower. Particularly large chunks of material can create an extra-bright fireball streak, but most meteors are still small enough to entirely burn up in Earth's atmosphere. If a meteor makes it to Earth it's known as a meteorite. Before they hit atmosphere the objects are called meteoroids.
This year's best meteor shower might be the Geminids in December, but if you don't want to skywatch in the cold, the summertime Perseids will also put on a show.
A research team claimed to have found the first known extraterrestrial protein, spotting it in a space rock that fell to Earth 30 years ago.
It's some next-level skywatching: Scientists are using images captured by NASA's InSight lander to look for meteors on Mars.
Scientists recently identified the oldest material on Earth: stardust that's 7 billion years old, tucked away in a massive, rocky meteorite that struck our planet half a century ago.
Early Saturday morning (Jan. 4), a strong display of Quadrantid meteors is likely for Europe and North America.
The 2020 Quadrantid meteor shower will peak overnight on Jan. 3-4, and the moon will be favorable to see the faint display of "shooting stars." Here's our guide.
As the 2010s come to a close, it's time to revisit how some of the biggest space science stories shaped the decade.
The annual Ursid meteor shower will peak during the overnight hours of Sunday (Dec. 22), into the morning hours of Monday (Dec. 23).
Scientists are scouring the remote Antarctic ice cap for rare meteorites chock-full of iron and holding secrets to the history of our solar system going back some 4.5 billion years.
NASA's record-breaking Parker Solar Probe has given us a new perspective on the famous Geminid meteor shower, which peaks this weekend.
The Geminids come from an asteroid, 3200 Phaethon, but scientists are still trying to figure out exactly how it sheds enough debris to produce the bright meteor shower.
A fiery explosion over the Australian desert may have been an ultra-rare minimoon, researchers think.
