Light trails streak across the Earth as star trails circle overhead in this stunning long-exposure photo taken by NASA astronaut Christina Koch at the International Space Station.
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.
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.
The Leonids take place every year in November. Once a generation, it is possible for a storm of meteors to occur with a peak of about 1,000 an hour – or even more.
A bright fireball meteor streaked across the night sky above Missouri Monday (Nov. 11), passing over St. Louis' iconic Gateway Arch.
