A New Story of Star Formation Unfolds NASA’s James Webb Space Telescope presents a new perspective on the Tarantula Nebula, or 30 Doradus, a region well-known to astronomers studying star formation. Its nickname originated from its resemblance to the spider itself. However, in Webb’s view, the over
Webb’s Near-Infrared Camera captured this mosaic image stretching 340 light-years across. It displays the Tarantula Nebula star-forming region in a new light, including tens of thousands of never-before-seen young stars that were previously shrouded in cosmic dust. Appearing pale blue, the most active region appears to sparkle with massive young stars. Scattered among them are still-embedded stars, appearing red, yet to emerge from the dusty cocoon of the nebula.
NIRCam was built by a team at the University of Arizona and Lockheed Martin’s Advanced Technology Center.’spresents a new perspective on the Tarantula Nebula, or 30 Doradus, a region well-known to astronomers studying star formation. Its nickname originated from its resemblance to the spider itself. However, in Webb’s view, the overall region takes on the appearance of a tarantula’s home—a burrow lined with its own spun silk.
Other areas appear dark, like in the lower-right corner of the image. This indicates the densest areas of dust in the nebula, that even mid-infrared wavelengths cannot penetrate. These could be the sites of future, or current, star formation. Located just 161,000 light-years away in the Large Magellanic Cloud galaxy, the Tarantula Nebula is the largest and brightest star-forming region in the Local Group, the galaxies nearest our. It is home to the hottest, most massive stars known to astronomers. Three of Webb’s high-resolution infrared instruments were focused on the Tarantula. Viewed with Webb’s Near-Infrared Camera , the region resembles a burrowing tarantula’s home, lined with its silk.
The harsh stellar wind from the massive young stars in the nebula is breaking apart molecules outside the pillar, but inside they are preserved, forming a cozy cocoon for the star. This star is still too young to be clearing out its surroundings by blowing bubbles – NIRSpec has captured it just beginning to emerge from the protective cloud from which it was formed. Without Webb’s resolution at infrared wavelengths, the discovery of this star birth in action would not have been possible.
