sci-fi 🤝 interferometry

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

If you wanna know what fringes are in interferometry, check this out: https://www.eso.org/public/teles-instr/technology/interferometry/

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

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/
