The Hubble Space Telescope photographed the elusive dwarf galaxy Donatiello II. It is one of three newly discovered galaxies, according to NASA. The international space agency said that the “old-fashioned way” was used to identify the galaxy – astronomers analyzed the data and then confirmed the discovery with a telescope. During the separation of stars, even a modern telescope can face difficulties, astronomers emphasize.

They are satellites of the larger Sculptor Galaxy (also known as NGC 253). This means that Donatiello II, III and IV are gravitationally bound to it. Thanks to the Hubble telescope, it was possible to obtain images of several faint galaxies with a long exposure. The pictures show a cluster of galaxies around the Sculptor. This was the confirmation of Donatiello’s independent discovery of galaxies. Read also: NASA discovered a planet the size of Earth
