Astronomers have discovered two new dwarf galaxies in the Milky Way's immediate neighbourhood. The dim clusters are both around 640,000 light years from our Sun, Reuters reports.
One of the new boys is located in the constellation Canes Venatici. The other, found in Bootes is the least luminous galaxy yet discovered. In universal terms it's a mere tealight, with a brightness of about 100,000 Suns.
