Asteroid Impacts Could Have Warmed Ancient Mars

Katherine Kornei, Science Writer by Katherine Kornei 17 April 202317 April 2023

Hydrogen released during large impacts might have boosted Mars’s surface temperature above freezing for thousands or even millions of years, enabling liquid water to flow over the Red Planet.

Impact Crater off the African Coast May Be Linked to Chicxulub

Katherine Kornei, Science Writer by Katherine Kornei 19 September 202213 October 2022

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.
