Last night’s moderate #SolarFlare likely released more energy than the majority of larger X-class events. Why? Flare classifications are determined by the flare’s *peak* emission. Although last night’s flare capped at an M3 level, it continued releasing energy for over 12 hours!

This artwork shows ice spires (around 100 metres tall) on the surface of the Jovian moon Callisto. The moon's parent planet, Jupiter, is in the sky, centre, with the other major moons either side of it. From the left, they are Ganymede, Io (casting a shadow on Jupiter) and Europa (covering Jupiter's might side). It is thought that these spires formed from an ancient impact billions of years ago. They are very slowly eroding over time, the ice subliming and dust within the ice accumulating to absorb Sunlight and continue the erosion. The Callisto-Jupiter distance is around 1.8 million kilometres, and Jupiter is around 140,000 kilometres across.

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

Menkib and the California Nebula. After failing to get the whole nebula into the FOV, I tried something different: focusing on the tension between that beast of a star and the nebula.
Gear: 130/910 mm APO, ASI 2600MM Pro & SHORGB filters. Total exposure: ~15 hours over 4 nights. #astrophotography

Greetings all, and I hope that the first complete rotation of our planet in this new year has been kind.

Here's an animation of the planet Mars rising above its innermost moon, Phobos, as the latter rotates.

Reflections and Returning to Writing (Or, Another Post About Self-Exploration Rather Than Space… It’s been almost exactly two years since I last posted here.

After a 2-year hiatus, I finally posted on Medium again (and after like 4 months off Bluesky, hello again!).

My goal for 2026 is to write more, and this felt like a good impetus to restart the blog and also explain where my head was at during my time away:
