Colorful cosmic "fireworks" decorate the night sky over the La Silla observatory in Chile in this gorgeous image by the European Southern Observatory's resident astrophotographer Petr Horálek.
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.
NASA's Terra satellite captured striking views of the meteor that exploded over the Bering Sea on Dec. 18, 2018.
Hundreds or millions of years after a meteorite smashes into Earth, researchers are left analyzing the impact site to figure out what happened.
The moon is shrouded by darkness and then re-emerges with dynamic color and activity in a new time-lapse video featuring this past weekend's total lunar eclipse.
There's a new satellite in space, and it was put there to drop "meteors" over the city of Hiroshima.
Japan launched seven spacecraft to Earth orbit today (Jan. 17), including a little satellite designed to create dazzling artificial meteor showers.
Asteroid impacts have a bad reputation here on Earth — it's the dinosaurs' signature public relations victory — but it's the moon that really bears the scars of living in our messy neighborhood.
A Japanese Epsilon rocket will launch a suite of seven experimental satellites this evening (Jan. 17), including one little cubesat that will test out creating artificial meteors.
The small asteroid that broke up over the city of Chelyabinsk, Russia, on Feb. 15, 2013, was a reminder about the importance of monitoring small bodies in space that could pose a threat to Earth.
The 2019 Ursid meteor shower will peak the night of Dec. 21-22, with expected rates of about 10 meteors per hour.
While the Taurid meteor shower doesn't have a lot of shooting stars to offer, the few that will streak across the sky may be bright and spectacular.
The Geminid meteor shower peaks the night of Dec. 13-14. This guide tells you the best times and places to see these shooting stars (no equipment necessary).
