The Apollo mission's latest discovery has been made - more than 50 years after it ended!

A recently opened sample is revealing more about one of the Moon’s most unusual structures - the Light Mantle.

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.

This is what a dust storm on Mars looks like.

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.

Find out what they reveal about the red planet 👇

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.

Fantastic news! And so well deserved!

Giulia is an amazing scientist and the best colleague.

Royal Astronomical Society @royalastrosoc.bsky.social · Jan 10

The Early Career Award in Geophysics goes to Dr Giulia Magnarini, of the Natural History Museum in London, in recognition of "her pioneering research using a multi-disciplinary approach to further our understanding of long runout landslides across the Solar System".

Well done Dr Magnarini! 👍 👏

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.

Some parts of Mars are deliciously colourful.

Here's part of the western Ladon basin, as seen in false colour by the CaSSIS instrumnet on the TGO spacecraft.

The disappearance of Lake Poopó, Bolivia.

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

Happy back to work day for me today.

So ignoring the inbox fire by staring at a random rock on Mars, like everybody should.
