Astronomers using the European Southern Observatory's Very Large Telescope (ESO's VLT) have found a rare disk of debris around a dead star that provides a glimpse of what may happen to our solar system. Unlike in similar systems previously found, the debris—the leftovers of planets that once orbited the star—is organized in a double disk, the two parts separated by a clear gap. The disk appears to be shaped by two planetary bodies, one possibly as big as Pluto, that have survived the violent death of the star.

Astronomers uncover a mysterious magnetic web above the Sun

The Sun’s seemingly peaceful regions are hiding a surprisingly complex magnetic world. Using a balloon-borne telescope high above Earth, scientists discovered delicate, thread-like magnetic structures woven through the solar atmosphere, apparently shaped by twisting motions on th
