Mars Imaged by Hubble

Astronomers using the National Science Foundation's Karl G. Jansky Very Large Array (VLA) have shown that a jet of material propelled from the core of a giant galaxy is channeled by a corkscrew-shaped magnetic field out to nearly 3,300 light-years from the galaxy's central supermassive black hole.
