M20 Trifid
#nebula, 5200 lightyears distant. A wonderful view with an amateur telescope and an easy target for astrophotography. Visual sketch & CCD image both by Xavier Bros: COAA Portugal &#Anysllum#Observatory@AstroSabadell GIF via@Tom_Ruen Thanks!pic.twitter.com/42JesfqBsO -
This is one of the nearest planetary nebulas: the Helix, 700 lightyears distant. It’s an old
#star loosing its external layers creating a nebula. It is expected our#sun will create a planetary#nebula in 5000 million years aprox. Image#Anysllum#Observatory@AstroSabadellpic.twitter.com/3ndG40nRc2

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: http://dlvr.it/RP8rjT .

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.pic.twitter.com/bgvqlTSqHc

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: https://bit.ly/2NY7hjS . Image: WIKIPEDIA/EDMONDO GNERREpic.twitter.com/utIQ8STki4
