Rings around Uranus

We don’t often get to see images of Uranus – and certainly none like this.

The astronomer Mike Brown took the photo a few days ago using one of the 10-meter twin telescopes at the W. M. Keck Observatory in Hawaii.

It’s an infrared image and clearly shows the rings which were discovered as recently as 1977. Several moons are also obvious – the brightest at top left being Miranda.

Mike Brown is the author of How I Killed Pluto and Why It Had It Coming. It tells the story of his work leading to the discovery of the then 10th planet. This was one of the factors leading to reclassification of planets and to Pluto’s demotion.
