These pictures from the widespread reaches of the Solar system continue to astonish me.

From Astronomy Picture of the Day for 28/11/21.

This is a photo of a kilometre high cliff – on Comet Churyumov-Gerasimenko. Taken by the Rosetta spacecraft.

It has a certain stark beauty.

Due to the comet’s low gravity you could jump off the cliff and likely survive.

Below is a video of the approach by the Rosetta spacecraft to comet Churyumov-Gerasimenko as posted on Astronomy Picture of the Day, 11/8/14.

The ambition of this mission is simply mind-boggling.

What weird things comets are though. Not quite what Jules Verne imagined I think.
