The #video lasts 1 minute but it corresponds to 10 hours.
The big dish is a decommissioned radio #telescope. In the background there is the 3.6-m telescope with its #exoplanet-hunting instrument #HARPS

This #picture is a #startrail taken from the dome of the swiss "Euler" #telescope at #LaSilla #observatory, in #Chile. The #camera was on the alt-az mount so it was tracking the stars horizontally. I tried to produced an artistic "raining star trail"... but I failed.

The first night of my run with #HARPS spectrograph at #LaSilla Observatory in Chile is tonight 🔭 ! I have been there for a few days and had new year’s eve at the observatory 💫 . I will observe seven nights for different programs that search and characterize #exoplanets with radial velocity. Everything is so beautiful and calm there.
Thank you @AlexSanterne for this amazing opportunity 🪐

The majestic view of the inner regions of our Galaxy spanning the #NightSky over #ESO #LaSilla #Observatory in #Chile. The green hue of #airglow is also seen, as is the blaze of the city lights of #LaSerena, 150 km away over the mountains to the left of the picture.

You certainly don't get #skies quite like this here in the UK! This is me under the spectacular #starry skies above the #ESO #LaSilla #Observatory in #Chile. Above and to the right you can see the Large and Small #MagellanicClouds. These are relatively small galaxies that orbit our #MilkyWay #Galaxy. Literally galaxy moons!

When I'm observing with large professional #telescopes, I always take the opportunity to capture #photography of the #night #sky. I drop my #camera somewhere in the #observatory, set the timer so that it takes #pictures automatically while I am busy hunting for #exoplanets. Before going to sleep, I collect my footage and process them while I rest.
This is an exemple #startrail I did 10 years ago from #ESO's #LaSilla observatory 🇨🇱, maybe one of my favorite
Enjoy !

This is the #ESO #picture of this week. It shows the 1.52m #telescope at #LaSilla #observatory 🇨🇱 observing the #MilkyWay thought the #dome's opening.
This telescope is now retired after almost 30 years to study #stars, #galaxies, #comets and even #exoplanets.
This telescope is the twin of the 1.52m telescope at #HauteProvence Observatory 🇫🇷 . Still used nowadays, the french brother has a new adaptive-optic (AO) test bench, 33 years after the first AO prototype for ESO (COME-ON).

We can clearly #airglow as well on this #photography I took from the #ESO #LaSilla #observatory, in #Chile 🇨🇱 .
This #FullSky #picture shows the #MilkyWay crossing the #sky above the #exoplanet hunter 3.6-m #telescope, currently used now by @asmasca.
The #orange light surrounding the sky, at the horizon, is not light pollution (there are some from the #Panamerica #highway), but #airglow.

#Mastodon is currently a bit slow because of the sudden increase in users doing their #twittermigration. I am sure it will get back to normal in no time.
As a welcome gift 🎁 , I am posting below my #bestof #timelapse #video from the #LaSilla, #LaPalma, and #HauteProvence observatories.
Enjoy !

First days visiting #ESO observatories. Needless to say, incredible sunsets from La Silla.
