Regulus Dwarf Galaxy
Leo I is a spheroidal dwarf galaxy in the constellation Leo, about 820,000 light years away from us. It is part of the Local Group and is thought to be one of the most distant satellite galaxies of the Milky Way.
Dwarf galaxies, including Leo I, are small objects that have virtually no dust and are not forming new stars. Leo I has a diameter of only 2,000 light years, and its mass is estimated to be around 25 million solar masses.
It was discovered in 1950 by Albert George Wilson on photographic plates taken with the Schmidt camera at the Palomar Observatory.
Leo I is only 12 arcminutes from Regulus, the brightest star in the constellation, and is practically hidden behind its halo. For this reason, the galaxy is sometimes called the Regulus dwarf. The light from the star makes it difficult to study the galaxy, and it was only noticed visually in the 1990s.
