First image taken James Webb telescope took place on July 11, and since then the program The science of early release contributed to the study of the entire scientific potential of the device. The Wolf-Lundmark-Melotti galaxy has already been carefully studied by the telescope Hubblewho observed space in visible light. Now the program’s scientists are using the star cluster as a way to compare Webb’s observations using infrared sensors.
According to scientist Kristen McQuinn of Rutgers University, one of the principal scientists of the Webb Early Release Science (ERS) program, calibrating the infrared system, NIRKam, helps develop software to measure the brightness of stars. “We want to make sure that we measure the brightness of stars very accurately and precisely,” the researcher notes.

The Beginning of the Universe and the Wolf-Lundmark-Melott Galaxy (WLM)
Wolf-Lundmark-Melott is not very far from us, at least by intergalactic standards. Milky Way🇧🇷 This characteristic probably means that it has not interacted with other systems and is almost in the formative stage, which can be used to study the evolution of these systems.
It got its name from the astronomers who discovered it: Max Wolff, Knut Lundmark and P. J. Melott. The gas that makes up the galaxy is very similar to those that were present in the beginning of the universe, with lighter elements such as helium and hydrogen. This is because when supernovae explode, they release new gases synthesized by stars.
“This makes the WLM very interesting because you can use it to study how stars form and develop in small galaxies like those in the ancient universe.” McQuinn points out. The scientist adds that “when determining the properties of these stars mass (as well as their age), we can get information about what happened in the very distant past.
