A Star-Formation Laboratory
The dwarf galaxy NGC 4214 is ablaze with young stars and gas clouds. The galaxy's close proximity, combined with the wide variety of evolutionary stages among the stars, make it an ideal laboratory to research the triggers of star formation and evolution.
Hubble Sees Stars and a Stripe in Celestial Fireworks
This image is a composite of visible, radio, and X-ray data of the full shell of the supernova remnant from SN 1006.
Starry-Eyed Hubble Celebrates 20 Years of Awe and Discovery
This brand new Hubble photo is of a small portion of one of the largest seen star-birth regions in the galaxy, the Carina Nebula. The image captures the top of a three-light-year-tall pillar of gas and dust that is being eaten away by the brilliant light from nearby bright stars.
