... STScI-PRC00-05 HUBBLE FINDS YOUNG STARS IN COSMIC DANCE This composite image, made with two cameras aboard NASA's Hubble Space Telescope, shows a pair of 12 light-year-long jets of gas blasted into space from a young system of three stars. The jet is seen in visible light, and its dusty disk and stars are seen in infrared light. These stars are located near a huge torus, or donut, of gas and dust from which they formed. ... The huge jet comes from one of the stars in this tight binary pair. ...

. While a Hubble Space Telescope image of visible light emitted by a protoplanetary disk in the Orion Nebula called proplyd 170-337 shows hot, ionized gas (red) surrounding and streaming off of a disk (yellow), 1.3 mm radio observations by CARMA and SMA reveal the dust disk hiding within the hot gas (contours). This protoplanetary disk has a mass more than one hundredth that of the sun, the minimum needed to form a Jupiter-sized planet. Bally et al 2000/Hubble Space Telescope & Eisner et al 2008/CARMA, SMA
