a Hubble Space Telescope Take a picture of the galactic system Arp 248, known as the Wild’s Triplet, which is located about 200 million light-years from Earth in the constellation Virgo. in galaxies The spirals appear to be connected by a luminous star bridge. The European Space Agency (ESA) stated that “this elongated stream of stars and interstellar dust is known as a tidal tail, and was formed by the mutual gravitational pull between the two fore galaxies”.

Wild’s Triplet is named after Australian astronomer Paul Wild, who studied the interaction of the galactic system in the 1950s. galaxies They get close to each other, they begin to interact with the force of gravity and it is possible that they become one.

The telescope was studying strange galaxies with the aim of finding candidates for future studies of James Webb And Hubble himself. “With so many astronomical objects to study in the night sky, projects like this one, guiding future observations, are a valuable investment of observing time. In addition to the scientific advantages of observing these strange and fascinating galaxies, they have also been – very unusual – chosen as targets. to the Hubble telescope because of its optical appeal to the general public,” the European Space Agency explained.
