Bulgaria: Bulgarian Astronomers Discover New Binary Star - Report File photo of the National Astronomy Observatory on Rozhen, the Rhodope mountans.

A new object in the Andomeda galaxy has been discovered by Bulgarian scientists working at the National Astronomy Observatory.

The discovery was announced on Monday by the Observatory, which is located in the Rhodope mountains. The newly discovered object is in the central part of the Galaxy and may turn out to be a variable star similar to the Mira star.

Mira is a binary star in the constellation Cetus, consisting of the red giant Mira A along with Mira B. Mira A is also an oscillating variable star and was probably the first non-supernova variable star discovered.

A star is classified as variable if its apparent magnitude as seen from Earth changes over time, whether the changes are due to variations in the star's actual luminosity, or to variations in the amount of the star's light that is blocked from reaching Earth.

The object, discovered by the Bulgarian astronomers using a Schmidt telescope, needs additional observations in order to be classified properly.
