A new image of the closest star-forming nebula to Earth shows the effect massive stars have in transforming the region.
Eventually, these newborn stars will begin ejecting tremendous amounts of radiation, blasting away the dust clouds that birthed them and reshaping the region again before they die in supernovas and once again enrich the region with heavy elements for the next generation of stars.
The transformation story told by the image also extends to the telescopes behind its creation. In 2020, the Spitzer Space Telescope was retired after 17 years of observing the universe in infrared. During its operational lifetime, Spitzer examined extrasolar planet temperatures, discovered aand assisted in spotting some of the most distant galaxies in the universe.
Launched in 2009, the WISE spacecraft was placed in hibernation after just two years. However, in 2013, NASA granted the telescope a second mission to search for near-Earth . Renamed NEOWISE, the mission is still operational today and has been used to set limits on the numbers, orbits, sizes and compositions of asteroids scattered throughout the solar system.
