Three energy-loss routes may explain Tarantula Nebula's X-ray shortfall
Like a collage made of layered sheets of colored cellophane, a vibrant new image layers observations of a famous star-forming nebula from NASA's space telescopes. The resulting cosmic "craft" reveals new details about the star-forming region known as 30 Doradus, or the Tarantula Nebula.
The Tarantula Nebula, also known as 30 Doradus, is a star-forming region located in the Large Magellanic Cloud, a small galaxy about 160,000 light-years from Earth. Recent observations using data from NASA's Chandra X-ray Observatory, James Webb Space Telescope, and Hubble Space Telescope have revealed that the nebula is losing energy through multiple routes.
Approximately half of the hot gas, heated by winds from young, massive stars, is leaking through the shell walls of gas and dust structures, escaping the nebula. Additionally, mixing between cold gas near the shell walls and hot gas is reducing the overall temperature of the gas. Lastly, the hot gas may be conducting heat by being in direct contact with cooler gas in the densest regions of the nebula.
These three channels for energy loss contribute to the nebula's complex display of X-rays, infrared, and optical emissions observed by NASA's telescopes.
