The most recent NASA picture provides remarkable information to a distant member of our galaxy's neighbourhood, the dwarf galaxy Wolf-Lundmark-Melotte (or WLM), which is just three million light-years away. Whereas Spitzer photographed blurry smudges of starlight years ago (still an outstanding performance for its day), However James Webb produced a wonderfully clean vision — one that almost appears to sparkle with stars too dim to detect earlier. Wolf-Lundmark-Melotte is a promising target for recreating events that happened billions of years ago since some of these stars originated in the early cosmos.
The JWST observation's degree of detail is not only remarkable but also revelatory. "We can see a myriad of individual stars of different colours, sizes, temperatures, ages, and stages of evolution; interesting clouds of nebular gas within the galaxy; foreground stars with Webb's diffraction spikes; and background galaxies with neat features like tidal tails," said Kristen McQuinn, a lead scientist with the Webb Early Release Science program.
WLM's relative distance from other objects in the Milky Way also helps to simplify the perspective and what astronomers may learn from it. Many of the nearest galaxies are interwoven and entangled with the Milky Way, making them more difficult to observe, Processes over the aeons have also left it with similar gaseous properties to the small galaxies of the young universe. With each new study of this dwarf galaxy — Hubble, Spitzer and now James Webb — scientists get a better picture of how stars may have evolved in long-ago galaxies. .
