![]() In this way, "James Webb" illuminates the early days of the universe. Because light takes time to travel through the cosmos, telescopes act like time machines: Observing celestial bodies at a great distance therefore always means looking into the past. These appear as if through a magnifying glass. The cluster of galaxies in the foreground focuses and distorts the light of the much more distant objects behind it. For example, it has set its sights on the galaxy cluster SMACS 0723, which acts like a gravitational lens. The strengths of the new ten-billion-dollar observatory also lie in the depths of space. Both celestial objects belong to our Milky Way. While the former announces the death of a star, the latter resembles a cosmic delivery room in which hundreds of suns give birth. Previously unknown richness of detail and unique dynamics are also revealed in the images of the Southern Ring Nebula and the Carina Nebula. "Many astrophysical processes are reflected there, which can now be studied with unprecedented precision." In the photo, the surroundings of Stephan's quintet appear in a dramatic view. "The special thing is not only the clarity and sharpness of the image," says Oliver Krause. Gas swirls around and new stars are born all the time. The group of five, at a distance of 290 million light-years, is quite close together, and the members influence each other due to their gravity. Galaxies are the main motif in the image of Stephan's Quintet, an ensemble of five Milky Way systems discovered by the French astronomer Edouard Stephan in 1877 in the constellation Pegasus.
