The stars were actually much farther away and part of the dwarf spheroidal galaxy
dubbed Bedin 1.
These properties led astronomers to classify it as a dwarf spheroidal galaxy
. Dwarf spheroidal galaxies are defined by their small size, low-luminosity, lack of dust and old stellar populations The international team of astronomers that carried out this study consists of researchers from University of California Los Angeles, University of Bonn in Germany and Universite de Montreal in Canada, among others.
Our next stop is the Fornax Dwarf Spheroidal Galaxy
(Fornax dSph), a Milky Way satellite at a distance of 470,000 light-years.

The HSC camera allowed the team to distinguish an overdensity of stars, which turned out to be a faint dwarf spheroidal galaxy
Some specific topics explored include the supermassive black hole in the Milky Way, optical to near-infrared light curves of classical Cepheids, young stellar objects in the large Magellanic cloud, dwarf Cepheids in the Carina Dwarf Spheroidal Galaxy
, and helium in the Galactic bulge.
Leo I is a dwarf spheroidal galaxy
discovered in 1950 by Albert George Wilson on a photographic plate taken with the 48-inch Schmidt camera at Palomar Observatory.
A further object for confusion is Leo I--a dwarf spheroidal galaxy
. It is about magnitude 9.8, and lies close to Regulus, only 12 arcminutes away from Leo's brightest star.
Computer models predict that in about four billion years the galactic pair will become one spheroidal galaxy
. Of course, by then Sun will have burned out - so others in the Universe will get to enjoy what should be a pretty spectacular fireworks display.
Based on this evidence, "I immediately jumped to the conclusion that this was a dwarf spheroidal galaxy
," Irwin says.
Due to these, scientists have determined that it is a dwarf spheroidal galaxy
, according to a report published in the journal (https://academic.oup.com/mnrasl/article/484/1/L54/5288002) Monthly Notices of the Royal Astronomical Society: Letters.
The dwarf spheroidal galaxy
Leo I hides within the glare of 1st-magnitude Regulus.
