This week, Nasa gives you the gif that keeps on giving. You're looking at the movement of Mars sand dunes, which is highly unexpected according to Nasa, due to the rarity of winds there, and Mars' thin atmosphere.
Less giffy, and more artful interpretation, is an artist's image of a black hole squashing new star formation.
The Herschel space observatory found that galaxies with the most powerful supermassive black holes at their centre are less likely to produce stars.
Nasa says that the radiation from active black holes can stop stars from forming.
We had a supermoon here on Earth this weekend, but on Saturn, there's a remarkable moon most days. Enceladus is exceptionally reflective, and in this shot it contrasts with Saturn and its rings. Titan looms at the rear in a galactic photobomb.
Nothing fascinates more than the sun, which the UK has been experiencing a distinct lack of lately.
A magnificent sunspot and M-class flare, which did not launch one of the more spectacular coronial mass ejections, was captured by Nasa's solar dynamics observatory.
This week we also saw a forst-of-its-kind image of a super Earth that radiates infrared light. The huge planet is just 40 light-years away from Earth, and is one of 70 known super Earths to be circling stars other than our sun.Suggest a correction
