A newly released image from a Mars satellite offers a glimpse into the complex past of the now dry and dusty world. From high above the surface of Mars, the orbiting High Resolution Imaging Experiment (HiRISE) homes in on the Danielson Crater, just north of the Mars equator. This region is intensely interesting to space … Read more
If you’ve ever lived with a cat, you’ve probably received a painful chomp from your beloved furball’s pointy canines at least once.

New satellite data has revealed the Arctic is melting at a “frightening rate” due to the excess heat caused by human greenhouse gas emissions. End-of-season Arctic multiyear sea ice – the ice that persists over several years – was roughly 50 centimeters (1.6 feet) thinner in 2021 than it was in 2019, the figures show, … Read more
A new ultra-powerful scan of the Great Pyramid of Giza using cosmic rays could reveal the identities of two mysterious voids inside.
