Astronomers have detected a small asteroid that doesn’t seem to want to go away. Called a quasi-satellite, this new companion circles around the Earth as it orbits the sun—and it’s going to stay that way for the next few hundred years.
A first-of-its-kind space rock filled with pristine material from the formation of the Earth itself has returned to the inner solar system, after billions of years in the cosmic boondocks. And it could help us piece together our planet’s origin story.
Astronomers have captured video evidence of a collision between Jupiter and a small celestial object, likely a comet or asteroid. Though it looks like a small blip of light, the resulting explosion was unusually powerful.
If an asteroid were closing in on our planet, we’d know about it quickly thanks to a dedicated network of astronomers. But this week, the Near Earth Object Coordination Center (NEOCC) had its eyes fixed on something else: two Mars-bound spacecraft attempting to escape Earth’s gravity well. And they did a bang-up job…
Sixty-six million years ago, planet Earth had a shit day when a six-mile-wide asteroid smashed into the Yucatán Peninsula, triggering a series of events that killed off the dinosaurs. Later this month, a scientific expedition will drill into the heart of Chicxulub crater for the very first time, seeking to learn more…
It’s home to just a half-million people, but Luxembourg is not thinking small when it comes to the future. Earlier today, this tiny European nation announced its intentions to back commercial asteroid-mining ventures, and in so doing, is positioning itself as an international leader in this promising area.
‘Tis the night before Christmas, and Asteroid 2003 SD220 is making its closest approach to Earth. NASA managed to snap a few pics of this pickle-shaped asteroid, which the space agency says poses no threat to our planet whatsoever.
Fresh off the heels of Spooky the Halloween Asteroid comes news of yet another celestial object coming to pay us a visit during an important calendar event. But have no fear, this space rock won’t be the Grinch that annihilated Christmas.
No one has managed to pluck valuable minerals from an asteroid quite yet, but when they do, the legal framework will be firmly in place: earlier today, President Obama signed the US Commercial Space Launch Competitiveness Act (CSLCA) into law.
Pixar’s The Good Dinosaur hits cinemas this Wednesday, just in time for the Thanksgiving holiday. And who better than Neil de Grasse Tyson to indulge in a bit of playful speculation about the film’s premise: what if the K-T asteroid that wiped out the dinosaurs 65 million years ago had missed Earth?
If you weren’t already having nightmares about the “Halloween asteroid” taking a detour and crashing into New York City, well, this space rock just got a little spookier. First off, Spooky isn’t an asteroid; according to NASA, it’s a dead comet. Worse! It looks like a haunted human skull.
On All Hallow’s Eve, an asteroid dubbed “Spooky” will make its closest approach to our planet. Hurtling along at an impressive 78,830 miles per hour, the 1,300-foot-wide object poses no threat to Earth...or does it? This Gizmodo video explains Spooky’s story.
We can expect a totally different kind of trick-or-treater this coming Halloween. A rather large asteroid—discovered less than three weeks ago—is set to to fly past the Earth at a distance not seen in nearly a decade.
NASA announced the finalists for its next round of planetary explorations. There were the usual suspects—Venus, Jupiter’s asteroids—and, then, there was this: An asteroid, composed almost entirely of (possibly magnetic) metal, with a crust literally beaten away by interstellar collisions, named Psyche. Pardon?
For nearly 40 years, paleontologists have argued over what really killed the dinosaurs. Was it an massive asteroid impact, or a spate of volcanic eruptions? Or what if a powerful impact ignited volcanoes, walloping Earth’s biosphere with a deadly 1-2 punch?
We once considered the Sun a planet, and it took finding Uranus to decide that moons should really be their own category of thing. These are all the places in our solar system that were once planets—but now have far more suitable names.
In celebration of World Asteroid Day this week, scientists came out of the woodwork to explain to all the different ways we can prevent an asteroid from causing an Armageddon-level apocalypse.
Here’s a really cool visualization from astronomer Scott Manley that shows what our sky might look like if we could actually see all the asteroids. Asteroids aren’t visible to the naked eye because they’re too small to register but Manley was able to reveal the known asteroids and speed them up to exaggerate how they…
Countries are scrambling to get to Mars in a good ol’ fashioned space race. But focus might be shifting to the red planet’s two moons. According to reports, Japan announced plans yesterday to bring its asteroid-probing technology to the tiny Martian satellites.
