A new paper from our group demonstrates the presence ammonium in the Orgueil meteorite and confirms its extraterrestrial origin through nitrogen isotopes.

A 40 million year spike in impact craters near the paleo-equator suggests that a large asteroid nearly hit the planet, broke apart from tidal forces, formed a ring, and then fell to the surface over millions of years.

China's Chang'e 5 mission brought back evidence that the moon had erupting volcanoes just 120 million years ago.

New study have discovered liquid water reservoirs 10-20km beneath Mars' surface using seismic data rom NASA’s Mars Insight Lander.

‘Head-scratcher’: first look at asteroid dust brought to Earth offers surprises (Ⓒ NASA/Robert Markowiz).

Smithsonian debuts first display of roughly 143mg fragment asteroid Bennu brought back to Earth by NASA's OSIRIS-REx mission. (ⒸSmithsonian/James Di Loreto and Phillip R. Lee).

New images from the Lucy Mission’s first asteroid flyby show that a satellite, already unexpected, is made of two objects – a contact binary. This is the first time we’ve seen a contact binary orbiting another asteroid. (Ⓒ NASA/Keegan Barber).

The NASA's OSIRIS-REx curation team has already collected ~70.3g of Bennu's material so far, and there is still plenty to come! (Ⓒ NASA).

The first glimpses of material from asteroid Bennu has scientists excited about what’s to come as the curation team continues the delicate process of disassembling the TAGSAM to reveal more of the OSIRIS-REx sample. (Ⓒ NASA/Erika Blumenfeld & Joseph Aebersold)

The "Prometheus" spatial mission aim to go into orbit around Jupiter and fly by its moon Io to target a volcanic plume (Prometheus) and fly through it (several miles above Io’s surface) to trap dust and gas from the plume in a pizza-sized collector. (ⒸNASA/JPL-Caltech/SwRI/MSSS/Brian Swift/CC BY)
