Using ALMA, two teams of astronomers have for the first time discovered a planet-forming disk with misaligned rings around a triple star system, called GW Orionis.

VLBA image shows details of a young jet emitted from the core of an active galaxy, revealing that the jet activity stopped, then restarted only a decade ago.

Fifty years ago, astronomers discovered carbon monoxide in space. It allowed us to see dark regions of the universe, and helped us understand it more clearly.

Join Melissa Hoffman of the National Radio Astronomy Observatory as she explains how astronomers are using new observations to answer a cosmic mystery.

Precision measurements made with the VLBA have revealed that a small, cool star 35 light-years from Earth is orbited by a Saturn-sized planet once every 221 days.

Planet-forming environments can be much more complex and chaotic than previously expected. This is evidenced by a new image of the star RU Lup, made with ALMA.
