Earth’s closest celestial neighbors—Mars and Venus—couldn’t be more different in regards to the environments that each planet is home to, but two new discoveries—an ancient glacier at Mars’ equator and active volcanism on Venus—just serve to accentuate the diversity that exists amongst our planetary siblings. First up, ice: evidence ofread more
A massive impact crater the size of the city of Paris that was discovered in 2018 under Greenland’s Hiawatha Glacier has been found to be much older than originally anticipated—tens of millions of years older, in fact. Initially thought to only be between three million and 12,000 years old, new datingread more
Researchers with Ohio State University have discovered 33 viruses that have been preserved for nearly 15,000 years in a glacier high atop the Tibetan Plateau, with 28 of these viruses not having been known to science before now. The ice cores that contained the viruses were obtained in 2015 fromread more
The findings of a new study on the large impact crater that was found under Greenland’s Hiawatha Glacier in 2018 suggest that the impact that formed the 31-kilometer (19.3-mile) crater occurred quite recently (geologically speaking, that is), at a time when the region was covered in a mile-thick sheet of ice, makingread more
