Let's test Sentinel-2 for night lights! This is a long-term dream of mine come true. Sen-2 sensors are not designed for night acquisitions, but we will try what they can do and see. Learn more here:

As you watch this, make that low-freq. rumbling sound in your head of the expanding cloud of debris and fire that comes from massive explosions. (this sound is in your head only, not in space)

We have successfully drilled 200 metres of sediment core from beneath the ice sheet at Crary Ice Rise! The pipe is still spinning - with a bit of time up our sleeve, we’re not stopping drilling yet, as we continue to drill back through the geological archive hidden beneath the ice. 📷 Ana Tovey

We’ve hit a century! 100m of core! Our night-shift crew took us past this milestone – we’re now more than halfway towards our target. Reaching this point is testimony to the skill and hard work of our drillers, who are clocking up long runs and cores of up to 3.1m 👉

A bit late in sharing, but we've successfully rotary-cored sediment under 523m of the ice sheet at Crary Ice Rise! This was a whole team effort, with special mention to our drillers and hot water crew. Watch the moment we got our first glimpse of the sediment we’ve been waiting on for so long.

eastern flank: a fissure opened at ~2100 m elevation, and a lava flow is descending through the desert-like Valle del Bove. Photos taken in the evening of 1 January from Etna's east and southeast flanks

Nice eruption (M7.1 flare) from AR 14324 to conclude 2025. It is accompanied by a coronal wave. The extent of the wave suggests we may be hit only by the western and southern portion of the CME, which may arrive early on 3 Jan 2026. Halo CME

Open up this picture fully. Then look at the surface of Mars. Then look up to the top right. Spot Mars' moon Phobos high in the sky. Then notice the bright spot beside Phobos. That's Earth.
