Earth's magnetic field is changing, with its weak spot (the South Atlantic Anomaly) growing significantly over the past decade.

No, it's not doomsday...but it does affect the radiation doses hitting satellite that pass through that region. 🧪🔭

This is very preliminary work, but it suggests that Roman in space is likely going to be much more stable than Hubble's current visible coronagraph on STIS. Even when you're not running at full bore, you should be able to achieve a lot of science. (original figure from Vanessa Bailey) #astrosci

I've got another new paper out this week, this time in Symbiosis! In this paper we use DNA barcoding to describe the diet of the sacoglossan sea slug Elysia diomedea from the Gulf of California, Mexico. Read it here: rdcu.be/ezcoD

The sea slug Elysia diomedea. The slug is green with some white spots on the body. The parapodia are quite ruffly with some yellow around the edges. The rhinophores of the slug have black and yellow stripes running from the tip towards the eye of the slug. The eye is a small black dot on the head. The slug is sitting on a mixture of red algae.

Saw the craziest variants of #sundials in the Germanic National Museum in #Nuremberg today. Cylindrical, octaedrical, cubic, like a funnel, etc etc pp. 🔭☄️

☄️ Comet C/2025 K1 (ATLAS) imaged a few days ago — still showing a small tail and magnitude 15. If it survives perihelion and maintains its activity, it could brighten to mag 7.5 and become visible with binoculars in October❗️👇

Comet C/2025 K1 (ATLAS) imaged on July 5, 2025, with an estimated brightness of magnitude 15 and a small tail only 1 arcminute long. Although it still appears distant and faint, it could become the next bright comet if it maintains its current activity level and does not disintegrate during its approach to the Sun. It might become visible with binoculars by late October, reaching a brightness of magnitude 7.5.

@esa.int Mars Express HRSC 2017-10-30 🧪🔭
The image shows Mars from space. You can see long, deep canyons with the huge Valles Marineris cutting through the surface. Noctis Labyrinthus looks like a maze of sharp, intersecting valleys. Two large volcanic features stand out, Tharsis Tholus and Ascraeus Mons, with their smooth, cone-like shapes rising from the surrounding. Colours are rusty red on the surface and foggy bluish in the canyons. Along the limb of the planet, a thin layer of atmosphere is visible, just before the darkness of space begins.

I saw this awesome image of the Sun when I visited Sendai observatory last year. Showing our beautiful star in 10 different wavelengths of light. Should have honestly bought a poster.
