🔭 Webb Just Captured the First Direct Image of Carbon Dioxide on an Exoplanet

｢ The achievement was made possible by Webb’s coronagraphs, which block light from bright stars as happens in a solar eclipse to reveal otherwise hidden worlds. This allowed the team to look for infrared light in wavelengths that reveal specific gases and other atmospheric details ｣

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 😀

This rare image taken on July 19, 2013, by NASA's Cassini spacecraft has shows Saturn's rings and our planet Earth and its moon in the same frame. At the time, Cassini was 2013 from a distance of about 898.414 million miles (1.445858 billion kilometers) from Earth. It is only one footprint in a mosaic of 33 footprints covering the entire Saturn ring system (including Saturn itself) taken by Cassini's wide-angle camera.
