Jupiter Made Our Solar System Weird

Wandering planet wiped out early super-Earths

(Newser) - As astronomers get a better look at the planets circling other stars, it's becoming increasingly apparent that our solar system is pretty strange—and Jupiter seems to be the reason why.

Jupiter's Great Red Spot Has Really Shrunk

It looks more like a circle than an oval

(Newser) - The signature red spot we see in pictures of Jupiter could fit three Earths next to each other—in the late 1800s. The Great Red Spot is getting smaller, and the reason is a mystery, Reuters reports. It was some 25,000 miles across in the late 19th century; by... More »
