1I/’Oumuamua, the first interstellar object to visit our solar system in 2017, belongs to a completely new class of space objects, scientists have discovered. It is a piece of an icy exoplanet, more specifically an “exo-Pluto,” a group of cosmic bodies that are highly unlikely to visit the Sun. “Everything about this object is consistent with it being a slab …

For the first time in tropical latitudes, scientists have sequenced ancient DNA from the only mammoth endemic to North and Central America: the Columbian mammoth. The research revealed unexpected — and as yet unexplained — genetic differences that made these animals distinct from their northern counterparts. Columbian mammoths (Mammuthus columbi) were approximately 13feet (4 meters) tall and towered over their …

Liquid water flowed across the surface of the asteroid that birthed the near-Earth object (NEO) Ryugu much later than scientists had thought possible, a new study finds.

Since February 2021, NASA’s Perseverance rover has been exploring a region on Mars known as Jezero Crater, a huge cavity believed to have once hosted a lake. It’s considered one of the most promising places to look for evidence of ancient life on the Red Planet (life as we know it, at least) — and there has been an update …

NASA‘s Perseverance rover has snapped an intriguing photo of a “turtle” appearing to poke its head out of its shell on the surface of Mars. The reptile-like structure is the latest in a long list of Martian rocks that look similar to living creatures or other Earth objects. Perseverance captured the new image on Aug. 31, on what was its …
