For the first time, astronomers have gotten an up-close view of eruptions from an asteroid, shedding light on what might drive such explosions.
Asteroids are space rocks thought to be the remains left over from the formation of the solar system. They range in size from tiny (the size of a car or so) to truly giant, with at least one - Ceres - gaining dwarf planet status. In our solar system, billions of asteroids are in the asteroid belt, a region around the sun between the orbits of Mars and Jupiter. Others stray from this region, and can potentially post an impact threat to the Earth. At least one interstellar asteroid, called 'Oumuamua, has passed through our solar system.

The European Space Agency has officially approved the Hera mission, which will assess the results of NASA's asteroid-walloping Double Asteroid Redirection Test.
A recent test of the ion engine that powers Japan's Hayabusa2 spacecraft went well, clearing the hardware for full-on operations soon, mission team members announced late last week.
Japan's enterprising asteroid-sampling spacecraft began they journey home Tuesday (Nov. 12), packed full of precious space rocks that scientists can't wait to get their hands on.
NASA's OSIRIS-REx spacecraft will "tag" asteroid Bennu at one of four potential sites next year. See close-up views of the four candidate sites here!
Hayabusa2's team — despite encountering a rockier surface than expected — made flawless touchdowns twice on an asteroid. Yet there are no plans for a "Hayabusa3," at least right now.
The pace of finding threatening near-Earth objects is slowing, so the community is looking forward to a new space telescope to help in its quest to locate 90% of all city-threatening worlds.
The asteroid Hygiea may qualify as a dwarf planet — and it could steal the title of the smallest dwarf planet in the solar system!
An enormous asteroid flew by Earth today (Oct. 25), and you can watch it zip by in a video from the Virtual Telescope Project.
The first mission to visit a mysterious swarm of asteroids that circle the sun along Jupiter's path has cleared an important hurdle on the way to its 2021 launch.
A fast-moving visitor is approaching our cosmic neighborhood. Dubbed 2019 SX5, this near-Earth object is about the size of the Great Pyramid of Giza.
When 'Oumuamua passed through our solar system in 2017, no one could figure out where the object came from. But astronomers think they've worked out how Comet 2I/Borisov got here.
Chilean officials are investigating a curious collection of burning objects that fell onto parts of the country last week.
