The Phantom Galaxy, formally known as M74, is a kind of spiral galaxy known as a “grand design spiral.” This means that it has well-defined spiral arms, visibly winding out from the center in the newly released images.
The Webb telescope also used its Mid-InfraRed Instrument (MIRI) to examine the Phantom Galaxy as part of a project to understand the earliest phases of star formation, ESA noted.
While Webb is best at observing infrared wavelengths of light, Hubble has particularly sharp vision at ultraviolet and visible wavelengths, according to the agency. This allowed it to reveal particularly bright areas of star formation, known as HII regions, in the Phantom Galaxy images.
The combination of data from both telescopes allowed scientists to gain an even deeper understanding of the Phantom Galaxy — and to create spectacular images of the cosmos.
