A view of the Natural History Museum, London, particularly its old Waterhouse building. The sun is setting in the distance, through the branches of large trees in the garden. Smaller trees are scattered in the foreground, with the sky turning a murky orange at dusk.

Oh but the light was so lovely leaving work today.

An oblique view of a glaciated landscape on Mars. A lobate valley glacier extends towards the viewer from a small valley, and terminates in a lobe. Flow-related structures are visible on the surface.

We have an STFC-funded PhD project at the @nhm-london.bsky.social. Work with me, @joemcneil.bsky.social, @katie-h-joy.bsky.social, and Gareth Collins, and share in the fun of secondary impact craters and landing sites!

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!

Many years ago, I got the train to Edinburgh, and spent the journey reading a Culture novel. When I got off, Iain Banks was right there on the platform as I opened the door.

He was meeting someone (else) from the train. I was too shellshocked/awkward to do anything but stare dumbfounded.

Do other people have a favourite landslide?

If not, consider adding this one on Mars. The colour from the CaSSIS instrument is just amazing.

Mysterious Martian mounds formed by ancient water Over 15,000 mounds are scattered across Mars’ lowlands – but until recently, no one knew how they got there.

Interested in some #Mars news this Monday?

The origins of more than 15,000 mysterious mounds on the red planet have been revealed, having been carved out of the surface by water billions of years ago.

It's a commonly-used phrase for an image that is real 'colour', but isn't as the human eye would see it.

In this case, RGB colours correspond to near-infrared (940 nm), red (678 nm), and blue (495 nm) wavelengths.
