The HiRISE (High-Resolution Imaging Science Experiment) instrument on NASA’s Mars Reconnaissance Orbiter (MRO) has given us a steady stream of images of the Martian surface. It’s been in orbit around Mars since March 2006, and has greatly outlived its intended mission length.
One of the latest Hi-PODs, or HiRISE Pictures of the Day, is this one, of sedimentary rock on Mars being eroded away.

“This moon might look a little funny to you, and that’s because it is an impossible scene,” wrote photographer Andrew McCarthy on Instagram.
He was talking about his other-wordly, almost Shakesperean image of the Moon. And that’s because this is an ‘all-terminator’ image.

There are all kinds of odd things in the sky. Things that defy our naming conventions, and our attempts to understand them. For instance, NGC 4618, the one-armed galaxy.

I know you’re Googling “flocculent” right now, unless you happen to be a chemist, or maybe a home brewer.
You could spend each day of your life staring at a different galaxy, and you’d never even come remotely close to seeing even a tiny percentage of all the galaxies in the Universe. Of course, nobody knows for sure exactly how many galaxies there are. But there might be up to two trillion of them. If you live to be a hundred, that’s only 36,500 galaxies that you’d look at. Puts things in perspective.

Artist Mik Petter has created a vibrant new piece of art based on JunoCam images of Jupiter’s Great Red Spot (GRS). The piece makes use of fractals, which are recursive mathematical creations; increasingly complex patterns that are similar to each other, yet never exactly the same.

There may be no life on Mars, but there’s still a lot going on there. The Martian surface is home to different geological process, which overlap and even compete with each other to shape the planet. Orbiters with powerful cameras give us an excellent view of Mars’ changing surface.

Confucius said, “Everything has beauty, but not everyone sees it.”
When it comes to Jupiter, Gerald Eichstädt and Seán Doran can certainly see it. And lucky for us, they have the skill to bring that beauty to the fore for the rest of us to enjoy.
