Asteroids

A sizable crowd turned out to see a small rock as the Smithsonian debuted the first display of a piece of the asteroid Bennu from the sample recently brought back by NASA's OSIRIS-REx mission.

NASA's Lucy spacecraft just flew by its first asteroid — and discovered that the space rock has a companion.

NASA's Lucy mission is set to visit several asteroids over 12 years, and the probe just successfully flew by target number one.

Rocks formed during the Chicxulub asteroid impact reveal fine dust particles were main drivers of the global winter which led to extinction of 75% of Earth's species.

On Wednesday, Nov. 1, NASA’s Lucy spacecraft will make its first flyby of an asteroid, zooming past a space rock named Dinkinesh before heading to the Trojan asteroids of Jupiter.

I use moon and Mars rocks in my teaching and have a modest collection of meteorites. I marvel at the fact that I can hold in my hand something that is billions of years old from billions of miles away.

The public will get its first direct look at a fragment of the asteroid Bennu when the Smithsonian's National Museum of Natural History debuts its display of the NASA-returned sample on Nov. 3.

Scientists have confirmed that OSIRIS-REx brought home at least 70.3 grams of material from asteroid Bennu, surpassing its intended goal of 60 grams.

Naturally occurring superheavy elements beyond those listed in the periodic table could potentially explain why asteroid 33 Polyhymnia is so dense, new research suggests.

A new NASA video explains what will happen when the space agency's Lucy probe flies by the space rock Dinkinesh on Nov. 1, in a test ahead of its trek to the Trojan asteroids in Jupiter's orbit.
