It’s a bad look.

Hiya! Over the past few months I've been silently working on several astronomy projects. Here's what I've been up to lately! 🔭☄️🧪
1. I discovered a Kuiper belt object! (2013 CG269)
2. I'm coauthor of a brand new paper by @renerpho.bsky.social et al. on the rotation of asteroid Bradyharan!

The Presidents Budget Request for NASA is out. It’s a bloodbath

Canceled are DAVINCI, VERITAS, Juno, OSIRIS-APEX, US participation in ExoMars and EnVision…

Huge cut to R&A. No funding to begin development of the Uranus Orbiter.

If you’ve ever cared about NASA, time to contact congress.

A map-projected mosaic of JunoCam images PJ70_26, PJ70_28 and PJ70_29 obtained on March 2, 2025. Approximately true color/contrast and enhanced versions. The North Temperate Belt outbreak is prominent near latitude 30 degrees north. This area has changed completely since early January.

With #LPSC2025 about to start, it's time to share what I've been working on during the last months and will be presenting at the conference.
This is a new high resolution 3D model of the Mont Mercou outcrop in Gale crater, that I made during my recent internship at LPG Nantes. #planetsci 🧵

Work in progress: Test renders using an improved Voyager 2 global Jupiter map. Approx true color/contrast (usually not very trivial when processing Voyager images) and a heavily processed enhanced version where the effects of the varying illumination also have been removed. The map is not yet global

The @esa.int Gaia satellite will take its final scientific measurements on Wednesday. 🔭

This will conclude a 12 year series of continuous observations.

Larger Gaia data releases are still in progress, but Gaia has already had a HUGE impact on our understanding of the #milkyway.

After several months of climbing up the steep slopes of the Jezero crater rim, Perseverance has reached the top!
The afternoon sun provides a spectacular view on landscape which the rover will explore soon! 🔭

Vesta from Dawn on Aug 20, 2011. Approx true color image and a false color one. The true color image is from red, green and blue images with the overall color corrected using Vesta's spectrum. The false color is from 918, 749 and 438 nm displayed as RGB. Each image is a mosaic of 17 color frames.

Allow me to fix this @gizmodo.com headline: "Rare asteroid sample contaminated by microorganisms after exposure TO THE AIR". This team from London received an asteroid Ryugu grain from JAXA's Hayabusa2 mission 🛰️. There were no Earthy evils when they received it from JAXA then... they exposed it. 🧪😑

#OPAG - Things in Magenta are the new orbits grey are the prime mission blue and red are the ones we're in now Between the red and the magenta we're going into the high radiation side 2nd placard shows where all the moons will be

#OPAG - Have a second extended mission proposal due in December 33 new orbits planned, will go into the rings and the intense radiation belts, inner moons, get a lot more occultations will get over the poles (true north & south) Get the night side perijove so we get a lighting campagin.

There’s more to rainbows than the human eye can see: here’s how a rainbow extends into the infrared and ultraviolet.

Photos:
1. Infrared
2. Visible (obviously)
3. Ultraviolet, and
4. A composite showing how UV is beyond the violet in a rainbow, and IR beyond the red end.

🚨🚨New paper alert!! 🚨🚨🧪🔭
Today we published exciting new results from the Rosetta mission! These results have big implications for where the comet formed and for whether comets could have supplied water to Earth. #PlanetaryScience #Rosetta 🧵1/n
