Dwarf galaxies are very small with some of them containing a merely 5,000 stars. One of the earliest dwarf galaxies discovered neighboring the Milky Way is the Sculptor Dwarf Galaxy, which scientists say is a perfect subject to study stars and galaxy formation in the early universe.

Researchers said that dwarf galaxies are very small and are also very difficult to see compared to the brightness of other objects in space. The Sculptor Dwarf Galaxy is a close neighbor of our Milky Way Galaxy. Despite their close proximity, both galaxies have distinct histories and characters.

The Sculptor Dwarf Galaxy, also known as the Sculptor Dwarf Elliptical or the Sculptor Dwarf Spheroidal, is a dwarf spheroidal galaxy. It is one of the 14 known satellite galaxies orbiting the Milky Way.

This galaxy is located in the southern constellation Sculptor and lies about 280,000 light-years away from Earth. The galaxy was discovered in 1937 despite its close proximity with Milky Way, as its stars are faint and spread thinly across the sky.

These dwarf galaxies are small, but nowadays, dwarf spheroidal galaxies play an important role in allowing astronomers to dig deeply into the universe's past.

Astronomers said they can determine the age of stars in the Sculptor Dwarf Galaxy because their light carries the signatures of only a small quantity of heavy chemical elements.

The Sculptor Dwarf Galaxy contains only 4% of the carbon and other heavy elements found in the Milky Way, according to a study released in 2009 by researchers at Cornell University.
