The ‘Donatiello II’ galaxy, located about 11.4 million light-years from Earth, was discovered by Italian amateur astronomer Giuseppe Donatiello. It is named after its discoverer.
British Daily Mirror and others reported on the 13th (local time) about Giuseppe Donatiello, an amateur astronomer who discovered the Donatiello II dwarf galaxy and the Donatiello II galaxy, which even the US National Aeronautics and Space Administration (NASA) and the European Space Agency (ESA) missed before their eyes. did.
The European Space Agency (ESA) shared a space photo on the 10th. What seemed like a simple random selection of a part of the vast universe was actually a picture of the Donatiello II galaxy. The ESA said, “If you looking at this picture haven’t discovered the Donatiello II galaxy, we’re in the same place. Because we couldn’t find it either.” ESA, which is operating the Hubble Telescope as a joint project with NASA, succeeded in photographing the location of Donatiello II through the Hubble Telescope, but the ‘galaxy identification algorithm’ created by NASA and ESA are all unable to identify the Donatiello II galaxy. failed to
After NASA and ESA’s galaxy-separation algorithms missed Donatiello II, all data taken over six years by the Hubble telescope was made available to the general public due to lack of funding for research. At the time of the release of the data, ESA thought that ‘amateur astronomers’, not algorithms or professional personnel, could help uncover ‘specialities’ remaining in the data.
ESA’s ideas fit nicely. Giuseppe Donatiello, a longtime amateur astronomer, took an interest in his data. After analyzing and processing his vast amount of data, Giuseppe was eventually able to discover as many as three new galaxies. The three galaxies have been named Donatiello II, III, and IV, respectively. An ESA spokesperson said all three galaxies are satellite galaxies of the Sculptor Galaxy.
An ESA spokesperson said of Giuseppe’s discovery, “Even the best algorithms are still limited in capturing very faint galaxies. In difficult galaxy identification processes, such as the case of Donatiello II, the ‘old-fashioned’ method of reviewing the data directly by a dedicated and talented person like Giuseppe is more effective.”
Giuseppe is known to have used the Victor M. Blanco telescope located in Chile to identify Donatiello II, III, and IV.
