A binary system observed by ALMA isn’t wonky, it’s the first example of an anomaly we only thought was possible until we saw it with our own eyes: a polar protoplanetary disk.

The most likely candidate for alien life outside out solar system, Gliese 581g, might not really exist.

An extrasolar Hot Jupiter called Upsilon Andromedae b has a hot spot in one of the strangest and most awkward possible places in its atmosphere and scientists aren't quite sure why.

The best way to find Earth-sized planets is watching them pass between a telescope and their parent star. And we might get a telescope designed to spot precisely that.

We've seen gas giants orbiting so close to their stars, their atmospheres are being stripped off. COROT-7b may show us what happens at the end of that process.

One of the weirdest extrasolar planets we've found so far is a superheated puffball that orbits its star in the wrong direction.

We knew planetary collisions should happen relatively often in young solar systems. Now we have hard evidence of one such an event.

Is VB 10 a planet-sized star, or is VB 10a a star-sized planet? One of our closest stellar neighbors poses a small but interesting challenge to cosmic taxonomy.

Welcome to the truly hellish world of WASP-12b, a planet being eaten by its star.
