What caused a tsunami 30,000 times more powerful than the December 26, 2004 Indian Ocean tsunami? A new modeling study says this was one of the results from the Cretaceous Chicxulub asteroid impact.
Analysis of a meteorite that fell in Costa Rica shows that its parent body may resemble the asteroid Bennu.
The underwater crater, spotted serendipitously in commercial observations of seafloor sediments, is believed to have formed at roughly the same time as the famous Cretaceous-Paleogene impact event.
After an exciting encounter with asteroid Bennu, the OSIRIS-REx mission team looks forward to hitting pay dirt when a hefty sample of ancient planetesimal material is delivered to Earth next year.
The Gaia mission’s asteroid survey will help dig deeper into the solar system’s rocky history.
A new method, nano-FTIR, is used to examine microstructures and processes on grains, displaying its benefit for examining asteroid returned samples through a meteorite.
Greenland’s Hiawatha impact structure, more than 30 kilometers in diameter, is much older than previously thought, new results suggest.
When an asteroid struck South Africa during the Precambrian, earthquakes rocked the region for millennia as Earth’s crust reequilibrated, new research reveals.
Spectral data and modeling suggest that volatile-rich main-belt asteroids initially formed at much greater distances from the Sun (>10 AU).
By using data from two lightning-spotting satellites, researchers measure explosions of thousands of small meteors and create a database that could help the planetary defense community.
