Galassia-NGC4151-675


Embargoed to 1800 Wednesday November 26
Undated handout photo issued by The University of Southampton of the spiral galaxy NGC 4151 as a new way of measuring precise distances to galaxies tens of millions of light years away has been developed by UK scientists. PRESS ASSOCIATION Photo. Issue date: Wednesday November 26, 2014. 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, which is published in the journal Nature, was used to identify the accurate distance of the nearby NGC4151 galaxy, which wasn’t previously available. See PA story SCIENCE Galaxies.
