A research team headed by University of Colorado astronomer John Bally released an image Thursday morning of a cosmic jet that resembles a huge, multicoloured tornado whirling through space.
The infrared image was captured by the Spitzer Space Telescope, built in Boulder by Ball Aerospace &...

Herbig-Haro object #1 and #2 are formed when a surrounding the cloud is heated by shock waves from jets of high-speed gas being ejected from a newborn star. Because the star itself is embedded in a dusty cocoon, the Herbig-Haro objects provide the only visible clues to physical processes occurring i...

Astronomers find jets everywhere when they look into space. Small jets spout from newborn stars, while huge jets blast out of the centres of galaxies. Yet despite their commonness, the processes that drive them remain shrouded in mystery. Even relatively nearby stellar jets hide their origins be...
