On Tuesday, NASA released a comprehensive image from the Hubble Space Telescope featuring all of the colors it can detect in the Hubble Ultra Deep Field (HUDF), both visible and invisible.
As NBC News reports, the HUDF catalogs thousands of galaxies in the constellation Fornax. Previous images captured everything but near-ultraviolet light — from near-infrared through the visible spectrum, plus far ultraviolet. "The lack of information from ultraviolet light made studying galaxies in the HUDF like trying to understand the history of families without knowing about the grade-school children," Caltech's Harry Teplitz said in a statement.
The gap was filled with observations from the Wide Field Camera 3. Ultraviolet light comes from the largest, hottest, and youngest stars, and by looking at this new picture, astronomers will likely be able to understand how galaxies grew through forming small collections of hot stars. --Catherine Garcia
