Astronomers at the European Southern Observatory (ESO) are taking a new, up-close look at one of our most elusive neighbors: the Sculptor Dwarf Galaxy.
Located some 280,000 light-years from Earth in the Sculptor constellation, the dwarf galaxy can easily be mistaken for a simple cloud of faint stars. But on Sept. 16, the ESO released a new moving image (above) of the dwarf galaxy, showing its ghostly stars in all of their glory.
The Sculptor Dwarf Galaxy was first spotted in the late 1930s by American astronomer Harlow Shapley (1885-1972). It's home to ancient stars that have remarkably similar chemical make-up to the oldest stars in our Milky Way.
Now astronomers are hoping to examine the dwarf galaxy's stars to learn more about the earliest periods of star formation. Twinkle, twinkle.
