M20 Trifid #nebula, 5200 lightyears distant. A wonderful view with an amateur telescope and an easy target for astrophotography.

#Betelgeuse: an enormous red variable star (magnitude 0-1,5), currently in a strong minima (aprox 1,5 by AAVSO ). See its light curve in 2003-04 according my observations: it was brighter, mag. 0.5-0.8.
Will it became a supernova? Yes, but nobody knows when.

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.

Found in Siberia a multi-functional tool, which can cut whatever you like, (butcher) and process skin, or make other tools: a "Palaeolithic Swiss Army knife" done by #Neanderthals 60.000 years ago: bit.ly/31gsDhM. Image: Institute of Archaeology and Ethnography of SBRAS pic.twitter.com/QOlsUT7cM4

It was “the little” ice period. Not a real ice period that happened centuries before. The ice period was a hard and very cold period.

Co2 is increasing for industry and fuel, and temp is increasing too. All scientists know that. It is not question of socialists is a question of evidence. Please I will finish this discussion now. I should do other things. Have a nice day and avoid ideology. I am not a socialist.
