Please welcome on Mastodon the @esoastronomy European Southern Observatory (ESO), the European organization that builds and operates large, advanced ground-based observatories for research in astronomy and astrophysics.
🐈⬛ Black Holes May Be ‘Supermazes’ of Many-Dimensional Strings • SciAm
「 Scientists would like an ultimate theory that can describe both the very tiny machinations of particles and the grand movements of galaxies. The insides of black holes, which are extremely small and extremely massive, are the ideal testing grounds for trying out such a theory 」
💥 What Will the Betelgeuse Supernova Be Like - And Will It Hurt Us? • Universe Today
「 It will be visible during the day. It will be brighter than any planet. It will be almost as bright as the full moon. You'll be able to read a book by the light of the Betelgeuse supernova at midnight 」

Hello #FediScience, migrating from astrodon.social (about to close), I am joining you here (inspired by @wolfgangcramer), so it's time for a new #Introduction
I'm Alexandre Santerne (call me Alex), #astronomer working @LAM_Marseille & teaching at Aix-Marseille #University (France).
I'm expert in finding #NoPlanetB 😀 ( #planets around other #stars).
I want to work in a #fair, #inclusive, and #sustainable #research #environment, so I (try to) act accordingly. I'm a member of @labos1point5
I toot a lot about #Astronomy, #Astrophysics, #Space but also a lot about #ClimateChange and #Climate.
Since 2019, I completely boycott planes, and I travel by #train (long distance) and #bike (short distance) as much as I can.
My other interests include #photography (visit my Flickr gallery in my profile) #Astronomy#Space
Oh, in case you don't know where Aix-Marseille is (trick: in 🇫🇷 ), the image below (credit: #NASA / JPL-Caltech / Space Science Institute) is indicating where I am, as seen from #Saturn...
... and where you also are, together with 8B people as part of 2M species 😀
One of them is our Extremely Large Telescope, currently under construction in #Chile. It will have a 39 m mirror, and its rotating enclosure will weigh 6100 tonnes, or about 700 mastodons!
We’re looking forward to chatting with all of you about #astronomy
