1/4 "All those protoplanetary discs will be lost, like tears in a rain of ultraviolet photons."

Ok, it doesn't sound as cool as the actual quote, but still 😉

This tear-shaped object is a protoplanetary disc –the birthplace of planets around another star– observed with ESO's Very Large Telescope. Material from the disc is being stripped away by a bright star beyond the upper-right corner, outside of the field of view, hence this cometary shape.

2/4 This type of object is known as "proplyd", short for "protoplanetary disc", although the term is most often associated to discs being ionised by other bright nearby stars.

This particular object is called 177-341 W and is located in the Orion Nebula, as shown below. Thanks to adaptive optics we can correct atmospheric turbulence and get super sharp images!

3/4 The data was obtained with the MUSE instrument at the VLT. MUSE doesn't take images per se. Instead, it breaks the light coming from every single location within its field of view into a rainbow or spectrum, which tells us a lot about the physical properties of this object.

We can then reassemble all these spectra into thousands of images at different wavelengths: https://www.eso.org/public/videos/potw2423a/

Silly and very niche pun brought to you by the fact that I've started re-watching 'Fringe'.

The more I use @phanpy the more I love it. One of my favourite features is the catch-up tool, which allows you to fetch all posts within the last X hours and rank them however you want.

Oldest first is particularly useful to catch up with folks in very different timezones. You can also rank by number of replies, boosts... even by "density" of information (denser posts: longer ones or those with multimedia content). You can even group posts by author.

What a great #mastodon client!

@lffontenelle I don't remember having seen or boosted that, but it's pretty epic :D

Soon the telescope platform at ESO's Paranal Observatory in will look very different at night: all four of the 8.2 m telescopes of the VLT will be equipped with lasers! This is one of the ongoing upgrades of the GRAVITY+ instrument, which will allow us to study black holes, stars and planets like never before.

Find out more in this great article by current and former ESO communication interns Elena Reiriz Martinez and Tom Howarth: https://www.eso.org/public/blog/gravity-leap-vlti/

@ghostdancer Fun (and true) fact: when we turn on/off the lasers at the UT4 telescope the consoles play a lightsaber sound :D

@freakazoid I think Lick was one of the first (maybe the first?) observatories to have a laser guide star.

Après 9 ans et demi de tentatives, me voici recruté en tant qu'astronome-adjoint à l'Observatoire de Paris : ne comptez pas sur moi pour cacher ma joie et mon bonheur. Quel honneur en plus d'être si bien entouré sur cette liste, bravo à toutes et à tous.

https://cnap.obspm.fr/

Grosse pensée aussi pour ceux qui ne sont pas là et dont on ne parle pas. Courage à vous.

How did we go from "problem --> solution" to "here's a rock that somehow connects to the internet, it's $500 or $700 if you want it with #AI"

1/2 I still struggle getting used to the fact that the smallest mirrors of the Extremely Large Telescope are similar in size to the primary mirrors of many current telescopes!

The M5 – the fifth mirror in the optical path – has reached a key milestone: its blank, the piece that will be later polished, has been finalised.

2/2 This flat elliptical mirror measures 2.7 by 2.2 metres. It's the largest tip-tilt mirror in the world: it will move without bending about 10 times per second.

It will work together with the M4, a very fast deformable mirror, to correct perturbations caused by the telescope mechanisms, the wind and atmospheric turbulence.
