I find this image remarkable.
It's of the nucleus of comet 67P/Churyumov–Gerasimenko, photographed by the ESA Rosetta spacecraft.
That bright white plume is a jet of dust and water ice blasting from the nucleus—helping form the comet's long, dusty tail as it approaches the Sun.

We have upgraded our geomagnetic forecast today (12 November 2025) to the highest intensity level amid an ongoing solar storm.
Current predictions suggest that the activity will result in potentially the largest solar storm to hit our planet in over two decades.

Fake cobwebs like these may look spooky – but what's really scary about them is that they can trap & injure wildlife, including birds, insects & small mammals. And fake webs aren't recyclable – so will end up in landfill for many years.

NASA has announced its newest astronaut class, and it includes Lauren Edgar—a bona fide geologist!
She joins Jessica Watkins as the second (to my knowledge) geology-trained scientist currently in NASA's astronaut corps.
This bodes super well for going back to the Moon and on to Mars!

Kyanite is cool, but it's not "literally from the core of a small planet" cool, or "makes beautiful geometric patterns when polished and etched" cool, or "travelled through space as part of a meteoroid for a billion years or so" cool - so this one is an easy one for me: vote #taenite! #MinCup25

An Earth-facing #SolarFlare has just launched a coronal mass ejection towards Earth. The flare is only moderate in size, but well placed for the eruption to hit us. We’re not talking about anything extreme, but simulations will give a better idea of the likely impact timings and effects soon.
