Hello BlueSky! I’m a spacecraft systems engineer, currently working on crewed moon landers. I’ll mostly be lurking around here, appreciating your space, science, and engineering related content, and maybe occasionally sharing a mediocre astrophoto of my own now and then. See ya around! 🦋

🔭 Bricolage de ces derniers jours : PANOPTES 🤩 C'est un petit télescope automatisé pour détecter des étoiles variables. On le fabrique à Callista à l'EPFL 🇨🇭 mais c'est un projet international pour sensibiliser des élèves des pays du Sud Global aux sciences en leur faisant fabriquer et opérer 🧪

Télescope PANOPTES quasiment terminé sur sa monture. Il ressemble à Wall-E avec ses deux gros yeux

Over on Mastodon, I have found a lot of people who are interested in the SuperNova Early Warning System.

Emails and texts to be automatically sent in the event of the neutrino detectors all spiking at once, to give advance notice for anyone who wants to see the flash: snews2.org

Explain your username:

IRAS 07572-3100 is a star that had a huge infrared brightening beginning in 2015 and created a new nebula. I discovered that brightening and the nebula. (see also www.astronomerstelegram.org?read=14416)

we tried to observe Comet C/2013 A1 Siding Spring back in 2014 with same result (no detection)

flat-frame calibration on massive scale!

You glow girl! ✨

At NSF–DOE Rubin Observatory, the secret to achieving a glowing-from-within look is our calibration screen.🔭 🧪

It's glamorous, we know 💅

An ominous blue donut-shaped ring surrounded by a thin red ring glows ominously in the dark to the left. To the right, Rubin's large steel telescope mount structure is barely visible, softly illuminated by the glow.

An #asteroid passed just 300 km above Antarctica earlier today. It was not discovered until hours after close approach.

“images” meaning artistically-rendered contour lines, intentionally misconstrued by the black hole imaging team as direct observation “photos”, implying they resolved discrete structural features in 1000x finer resolution than the underlying observations. The science is awesome. The PR is shameful.

seem to be a mixup. This makes no sense (article does not substantiate the claim)

Ryan Kinnett @rkinnett.bsky.social · 14d

What are you talking about? The quoted email says nothing whatsoever about layoffs. Where did “as many as 4,000” come from?

I'm hiring 1-2 postdocs this year! If you're interested in:

GW astrophysics
(Binary) Stellar Evolution
Stellar dynamics (esp. w/ massive BHs)
Galactic dynamics (inc. stellar streams)

plz consider applying! You don't need letters initially, just a list of references.

My telescope dome controller project is coming along nicely! Ready to install at Stony Ridge Observatory. I plan to post a parts list, STLs, & code when it’s done.

#Asteroid 2024 YR4 has a ~4 % chance of hitting the Moon on Dec 22 2032. A strike could spike micrometeoroid flux in low Earth orbit ~1000×, endangering satellites—so researchers even study nuclear disruption. arxiv.org/pdf/2509.12351

Last night it fogged over but I left the camera running in case it cleared. Woke up to an hour of the Ring Nebula (M57). I'm showing it starless and in an uncropped version for a reason. All the stars have been removed. Every point of light you see is a galaxy. #astronomy #astrophotography

Yesterday Curiosity took pix of jagged peaks in the distance with its ChemCam. I stitched them together, did some work on them, and... just look at that view... I've been doing this since Sojourner landed & this is one of my fave images ever... Credits: NASA/JPL-Caltech/LANL/S Atkinson

The first natural solar eclipse ever observed by a space-based coronagraph(?). Watch the lights go out as🌕zig zags between🛰️ &☀️

This could be a first. On Sept. 21st, NOAA's CCOR-1 coronagraph onboard GOES-19 observed a solar eclipse from🌎orbit.

Actuellement deux comètes présentes dans notre système solaire semblent se tirer la bourre. Leur nom de code : C/2025 K1 ATLAS (à gauche) et C/2025 R2 SWAN (à droite). En réalité leurs trajectoires respectives sont très différentes.

What a shot by CCOR-1 showing a CME (non Earth-directed) leaving the Sun with the moon in the foreground. Super cool!

Perseverance Rover reached a location on Mars which rises rock weirdness to a new level! Pattern like roots or splattered liquid glass and patches imitating lichens. The red material didn't move during brush cleaning by the robot. More from the same day Sep 20, 2025 on areo.info/mars20/ecams...
