This composite image shows the star-forming region 30 Doradus, also known as the Tarantula Nebula. The background image, taken in the infrared, is itself a composite: it was captured by the HAWK-I instrument on ESO\u2019s Very Large Telescope (VLT) and the Visible and Infrared Survey Telescope for Astronomy (VISTA), shows bright stars and light, pinkish clouds of hot gas. The bright red-yellow streaks that have been superimposed on the image come from radio observations taken by the Atacama Large Millimeter\/submillimeter Array (ALMA), revealing regions of cold, dense gas which have the potential to collapse and form stars. The unique web-like structure of the gas clouds led astronomers to the nebula\u2019s spidery nickname.<\/figcaption><\/figure>\n

Astronomers have unveiled intricate details of the star-forming region 30 Doradus, also known as the Tarantula Nebula, using new observations from the Atacama Large Millimeter\/submillimeter Array (ALMA). In a high-resolution image released today by the European Southern Observatory (ESO) and including ALMA data, we see the nebula in a new light, with wispy gas clouds that provide insight into how massive stars shape this region.<\/p>\n

\u201cThese fragments may be the remains of once-larger clouds that have been shredded by the enormous energy being released by young and massive stars, a process dubbed feedback,\u201d<\/em><\/p>\n

says Tony Wong, who led the research on 30 Doradus presented today at the American Astronomical Society (AAS) meeting and published in\u00a0The Astrophysical Journal<\/em>. Astronomers originally thought the gas in these areas would be too sparse and too overwhelmed by this turbulent feedback for gravity to pull it together to form new stars. But the new data also reveal much denser filaments where gravity\u2019s role is still significant.<\/p>\n

\u201cOur results imply that even in the presence of very strong feedback, gravity can exert a strong influence and lead to a continuation of star formation,\u201d<\/em><\/p>\n

adds Wong, who is a professor at the University of Illinois at Urbana-Champaign, USA.<\/p>\n
