Planetary nebulae are astronomy’s gateway drug. Their eye-catching forms make us wonder what process created them, and what else is going on up there in the night sky. They’re some of the most beautiful, ephemeral looking objects in all of nature.
The Hubble Space Telescope is responsible for many of our most gorgeous images of planetary nebulae. But the images are more than just engrossing eye candy. They’re documentation of a complex process that plays out over tens of thousands of years, all across the Universe.
And they’re a death knell for the star that dwells within.

Meet NGC 2608, a barred spiral galaxy about 93 million light years away, in the constellation Cancer. Also called Arp 12, it’s about 62,000 light years across, smaller than the Milky Way by a fair margin. The Hubble Space Telescope captured this image with its Wide-Field Camera 3 (WFC3).

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.
