Perseverance captured a new selfie to celebrate 1500 Sols on Mars.
The rover is currently investigating the outer rim of Jezero crater near an outcrop named Sally's Cove. #planetsci

This is what it would look like to fly over the Martian North Pole aboard @esa.int's Mars Express orbiter.
This sequence of 117 images was captured by the VMC camera on June 14th, 2019 over the course of 3 hours and is played a 1200x speed. #planetsci

Happy new year! My all sky camera imaged the sky every 15 seconds and this picture shows what happened in the sky in 2025. It shows the length of the night and day with the hourglass shape, the monthly lunar cycle with the diagonal bands, the elevation of the Sun at local noon, and lots of clouds.

Time for yet another megathread of my favourite satellite pics.
This time I have 123 images processed by me in 2025 *.
Various dates, random places.
Most of them were taken by Sentinel-2, some by S-3 and one or two by Landsat.
*There's one more pic that isn't mine, but it's so good 😊

Last night I set up my telescope so we could all watch the planets while waiting for the new year to arrive.
After the fireworks had subsided, I attached my camera and captured my first astrophoto of the year featuring Jupiter and its moon Europa. #astrophotography
Happy New Year everyone!

This paper by Vasilyak and Shubralova makes an interesting observation that ELVES #TLE seem to be more likely to occur near tectonic plate boundaries.
However, with just 37 events, I'm skeptical of the statistical significance of their results which isn't addressed in the paper at all. 🧪🧵

We call the very upper-atmospheric lightnings elves and sprites (which is itself great), and these events don't appear everywhere. The analysis in this study argues that elves are mostly occur along the tectonic plates' boundaries, which is slightly crazy. 🧪⚒️

Kudos to our project scientist who helps advocate for these every ~year when I think the view might work and we've got a little bit of energy and time spare in a plan. Doing the science on the day to day is important. Taking a moment now and again to do something just for art is important as well.
