There are sites that will describe this as “Aurora Caught by Hubble Space Telescope” and there are sites that will say “Something Weird is Spotted Coming Out of Uranus.”
This blog, for example, would never be caught making cheap double entendres about Uranus. This blog is alllllll about the dick jokes.
It is an aurora, like the ones we get (Jupiter and Saturn, too) and the brightest we’ve ever seen on Uranus, apparently. Uranus is hard to study because it’s a completely featureless frozen blue gas ball.
They used an ultraviolet doohickey built into Hubble to find this aurora — and interestingly proved that it moves with the rotation of the planet. They also managed to rediscovered the magnetic poles which have been missing pretty much ever since Voyager found them because, again, featureless blue gas ball.
Also, note rings.
Oh, hey, did you see the moon last night? Holy cow, was it huge! The news said it was going to be pink, but it was gold here. On the horizon, anyhow.
