    This is one of the nearest planetary nebulas: the Helix, 700 lightyears distant. It’s an old loosing its external layers creating a nebula. It is expected our will create a planetary in 5000 million years aprox. Image

    African population have 0.5% of their genome from Neanderthals. The genes have been carried to Africa by a human population that left Africa 100-150000 years ago, interbred with Neanderthals outside of Africa and then returned: . Image: M.Luk Princeton Univ

    The Nebra sky disc is 3600 yers old. It was found by treasure-hunters with a metal detector in Saxony in 1999. The bronze disk with gold symbols reveals an astronomical phenomena understanding combined with religious beliefs.

    Fossilized footprints show Neanderthals or other old hominids climbing the active stratovolcano Roccamonfina 345.000 years ago in Italy. Footprints were made just a few hours or days after a violent volcanic explosion: . Image: WIKIPEDIA/EDMONDO GNERRE

    70.000 years ago, a small red dwarf star, “Scholz’s star”, moved near our Solar System, just only 1 lightyear far the Sun, causing a perturbation in the orbit of some objects of the Oort Cloud: . Image: Jose A Peñas - SINC

    Solar System always surprises me! Ahuna Mons in , discovered by probe, is an amazing young criovolcano. Probably ejected ice in the past. Image done in 2016 by Dawn mission NASA.
