NASA’s WISE infrared space telescope is losing its refrigeration, but its backlog of data is still yielding cool images such this one of an odd, blobby, jellyfish-like nebula.
“I just happened to look up one of my favorite objects in our WISE catalogue and was shocked to see these odd rings,” said Michael Ressler, a member of the WISE science team at NASA’s Jet Propulsion Lab, in a press release.
The object, called the “Crystal Ball” nebula or NGC1514, is a planetary nebula located 800 light-years away in the constellation Taurus. Planetary nebulas form when a dying star puffs off its outer layers of material and illuminates the gaseous cloud from within. They’re called “planetary” because the first such objects discovered were roughly spherical, like a planet, although nebulas with lopsided wings are now known to be common.
In visible light (left image), NGC 1514 looked a lot like any other asymmetrical nebula. But WISE’s infrared image (right) shows loopy rings surrounding NGC 1514 that are unlike anything astronomers had seen before.
