Once every month, on average, somewhere on Earth a fireball appears out of nowhere and for mere seconds, casts a blinding flash across the sky before it blows up in a thunderous explosion. It happened last Saturday over southern Africa,

Bumper car-like interactions at the edges of our solar system – and not a mysterious ninth planet – may explain the dynamics of strange bodies called “detached objects,” according to a new study.

CU Boulder Assistant Professor Ann-Marie Madigan and a team of researchers have offered up a new theory for the existence of planetary oddities like Sedna.

Nearly all asteroids are so far away and so small that the astronomical community only knows them as moving points of light. The rare exceptions are asteroids that have been visited by spacecraft, a small number of large asteroids resolved by NASA’s Hubble Space Telescope or large ground-based telescopes,

A boulder-sized asteroid designated 2018 LA was discovered Saturday morning, June 2, and was determined to be on a collision course with Earth, with impact just hours away. Because it was very faint, the asteroid was estimated to be only about 6 feet (2 meters) across,

…

About 66 million years ago, an asteroid smashed into Earth, triggering a mass extinction that ended the reign of the dinosaurs and snuffed out 75 percent of life.

Although the asteroid killed off species, new research led by The University of Texas at Austin has found that the crater it left behind was home to sea life less than a decade after impact,

…

When the Chicxulub asteroid smashed into Earth 65 million years ago, the event drove an abrupt and long-lasting era of global warming, with a rapid temperature increase of 5 Celsius (C) that endured for roughly 100,000 years, a new study reports.

…

A new study has discovered the first known permanent immigrant to our solar system. The asteroid, currently nestling in Jupiter’s orbit, is the first known asteroid to have been captured from another star system. The work is published in Monthly Notices of the Royal Astronomical Society: Letters.

…

An asteroid around the size of a football field zoomed by Earth on Tuesday, but at a safe distance, the US space agency NASA said.

The space rock was discovered in 2010, but only recently did astronomers determine it would not collide with our planet,

ESO telescopes find first confirmed carbon-rich asteroid in Kuiper Belt

An international team of astronomers has used ESO telescopes to investigate a relic of the primordial Solar System. The team found that the unusual Kuiper Belt Object 2004 EW95 is a carbon-rich asteroid,

…

With just a few hours’ notice, a relatively large asteroid whipped through the Earth-moon orbit over the weekend. You may have missed it though; humanity only learned of the asteroid hours before the flyby.

A “Tunguska-class” asteroid was first spotted by the Catalina Sky Survey out of the University of Arizona on April 14.
