NASA and its partners, the European and Canadian space agencies, are celebrating the second year since the James Webb Telescope began sending back pictures of the universe. Description of the Penguin and the Egg galaxies. These are interacting galaxies known as Arp 142, 326 million light-years from Earth, captured in interactive light by James Webb.
Galaxies first interacted between 25 and 75 million years ago, giving rise to new stars. According to previous studies, between 100 and 200 stars form per year in Penguin — yes, that bird’s head-shaped galaxy in the center of the image — while the Milky Way produces only six to seven new stars per year. . In this image by James Webb, the interaction between the two galaxies is marked by a faintly glowing inverted U. Note that although it appears larger than the Egg galaxy to Penguin’s left, it has about the same mass. If both galaxies were smaller, they would already have merged.
In addition to the galaxies that stand out in the image, you’ll also see more distant galaxies in the background. The space agencies said it was “a testament to the sensitivity and resolution of Webb’s infrared cameras.” NASA and its partners has been activated James Webb Telescope in late 2021 after more than a decade of delays due to spiraling costs and construction difficulties. Agencies have released the first footage of him the deepest description of the distant universeIn July 2022. Last year they too celebrated its first anniversary with a description of the nearby star nursery.
