Amateur astronomer’s ‘ground-breaking’ discovery of new dwarf galaxy astounded scientists.

ASTROPHYSICISTS at the University of Surrey were taken aback when they learned that an amateur astronomer had discovered a dwarf galaxy more than 2.7 million light-years away.

Scientists anticipate that the discovery, named Pisces VIITri III, will give new light on how galaxies form. While browsing through a public data collection published by the DESI Legacy Imaging Surveys – a catalogue of photographs of the sky viewable from the Northern Hemisphere – amateur astronomer Giuseppe Donatiello found the celestial entity. Dr. David Martinez-Delgado of the Instituto de Astrofisica de Andaluca in Granada, Spain, has since examined the photos.

The astronomer was able to locate the galaxy’s exact location by comparing the find to deeper photos captured by the 3.58-meter Telescopio Nazionale Galileo in Italy.

Surprisingly, Pisces VIITri III was found as one of two viable options, and either one would “make it an important astrophysical finding,” according to the University of Surrey.

The galaxy is either an isolated dwarf galaxy or a satellite of the larger Triangulum Galaxy, according to the team’s estimates.

The spiral galaxy, also known as Messier 33 (M33) or NGC 598, is the third-largest member of the Local Group of galaxies, after only Andromeda and the Milky Way.

M33 is one of the furthest objects that astronomers can see with the naked eye from Earth.

The newly discovered Pisces VIITri III, on the other hand, cannot be claimed to be in the same category.

If the galaxy is proved to be an isolated dwarf galaxy, it will almost certainly be the faintest galaxy ever discovered by scientists.

Observations, on the other hand, may still show that the galaxy is a member of a small group of M33 satellites.

Astronomers claimed it will reinforce their views on how galaxies arise in the latter circumstance.

“Theoretical information about galaxy formation implies we’d expect to observe many more tiny galaxies around the Triangulum galaxy, M33,” Emily Charles, a PhD student at the University of Surrey who collaborated on the project, stated.

“However, it only has one known satellite at this time.”

“If this newly discovered galaxy is indeed part of M33, it could mean that there are many more out there that have yet to be discovered since they are too faint to be seen in prior studies of the system.”

“While M33 now casts doubt on astrophysicists’ assumptions, this latest discovery begins to reassure us that our theories are sound.”
