At magnitude 5.4, it can be seen with the naked eye, and it ranks 5th among the globular clusters in total brightness.
The astronomers that fortuitously discovered Bedin 1 were on a hunt for white dwarf stars in an effort to measure the age of NGC 6752 [...] it is roughly a thousand times dimmer than our Milky Way.

Bedin 1 is located in the Pavo constellation [...] Bedin said he pleased with the galaxy's new name, saying it was "nice to adopt a nickname from one of its discoverers instead of an anonymous identification based on its coordinates."
Object Position - R. A. 19:10:45.41 Dec. -59:55:04.32; Dimensions - Image is about 1 arcmin across (about 9,000 light-years); Instrument - ACS/WFC; Exposure Dates - September 9–13, 2018
Together, those porperties led astronomers to classify it as what is called a dwarf spheroidal galaxy. [...] Because it is so distant from any other galaxies – and so has been left largely undisturbed – as well as its old age, the astronomers refer to Bedin 1 as a fossil from the beginning of the cosmos.
Because of its 13-billion-year-old age, and its isolation — which resulted in hardly any interaction with other galaxies — the dwarf is the astronomical equivalent of a living fossil from the early universe. [...] The science team's results will be published online January 31, 2019, in the Monthly Notices of the Royal Astronomical Society: Letters.
Over 10 billion years old, NGC 6752 follows clusters Omega Centauri and 47 Tucanae as the third brightest globular in planet Earth's night sky.
The newfound galaxy, dubbed Bedin 1 in an acknowledgment of the scientist's singular role in its discovery [...] It's about 30 times smaller than the Milky Way and a thousand times dimmer.
...says Luigi Bedin, researcher at Osservatorio Astronomico di Padova (INAF)
The aim of their observations was to use these stars to measure the age of the globular cluster, [...] Bedin 1, which lies far behind the foreground globular cluster NGC 6752.
The find was fortuitous. An international team of astronomers was using Hubble's Advanced Camera for Surveys instrument to study white dwarfs [...] nicknamed Bedin 1, after discovery team leader L. R. Bedin of the INAF-Osservatorio Astronomico di Padova in Italy...
It lies about 30 million light-years from the Milky Way and 2 million light-years from the nearest plausible large galaxy host, NGC 6744. This makes it possibly the most isolated small dwarf galaxy discovered to date. [...] astronomers were able to infer that the galaxy is around 13 billion years old — nearly as old as the Universe itself.
