The two streams crossing the image are jets of hot gas, ejected from the poles of a protostar. If the jets collide with the surrounding gas and dust they can clear vast spaces, and create curved shock waves, seen as knotted clumps called Herbig-Haro objects.

Blazars are the most common sources detected by NASA’s Fermi telescope. As matter falls toward a supermassive black hole at the galaxy’s center, some of it is accelerated outward at nearly the speed of light along jets pointed in opposite directions. When one of the jets happens to be aimed in the direction of Earth, as illustrated here, the galaxy appears especially bright and is classified as a blazar. Image credit: M. Weiss / CfA.

This image shows an artist’s impression of the ten hot Jupiter exoplanets studied by the astronomers. The images are to scale with each other. HAT-P-12b, the smallest of them, is approximately the size of Jupiter, while WASP-17b, the largest planet in the sample, is almost twice the size. The planets are also depicted with a variety of different cloud properties. Image credit: NASA / ESA / Hubble.
