The Sculptor Galaxy, also known as NGC 253, now has a sharper and more fascinating face than ever before. Thanks to more than 50 hours of observation with the European Southern Observatory's (ESO) Very Large Telescope (VLT), astronomers have obtained the most detailed image of a galaxy ever made. The result is a breathtaking map composed of thousands of colors, each revealing the presence of different elements such as stars, gas and dust. This is not just a visual wonder: the chromatic richness of the new image has exceptional scientific value. Each hue is valuable data, allowing astronomers to precisely locate and analyze galaxy components. The study, published in the journal Astronomy & Astrophysics, is led by Italian astrophysicist Enrico Congiu of ESO, with participation from the National Institute of Astrophysics in Arcetri and the University of Padua. NGC 253 is located about 11 million light-years from Earth and spans about 65,000 light-years. To obtain such a high-resolution image, the researchers combined more than 100 previous shots collected by the VLT. Initial analyses of the new image revealed more than 500 planetary nebulae and numerous gas- and dust-rich regions ejected by dying Sun-like stars-a surprisingly large number compared to the observed average.
