I’ve worked at @nhm-london.bsky.social for a while now, and yet still have my mind blown on a regular basis. Today, 2 rocks from the collection:
Fulgurite (created by a lightning strike) collected by Charles Darwin.
Fossil leaf collected by Robert Falcon Scott (on the Terra Nova expedition).

The atmosphere of Mars is too thin to effectively shield it from small meteors hitting the surface.
Here, a new, small (10 m) impact crater formed some time between 2010 and 2019.
Although the crater is small, the effects are widespread, with the seismic energy triggering lots of dust falls!

Do other people have a favourite landslide?
If not, consider adding this one on Mars. The colour from the CaSSIS instrument is just amazing.

It was the second largest lake in the country, but is now unlikely to return. Caused by climate change and diversion.
