A NEW way of measuring precise distances to galaxies tens of millions of light years away has been developed by UK scientists.

Dr Sebastian Hoenig, from the University of Southampton, has created the method which is similar to what land surveyors use on earth, by measuring the physical and angular, or "apparent", size of a standard ruler in the galaxy, to calibrate the distance from this information. The research was used to identify the accurate distance of the nearby NGC 4151 galaxy, which wasn't previously available. The galaxy NGC 4151, dubbed the Eye of Sauron by astronomers for its similarity to the film depiction of the eye of the character in The Lord Of The Rings, is important for accurately measuring black hole masses.
