The black hole at the heart of M87 galaxy, brighter than its own galaxy has now got scientists thinking it may be larger than originally thought.
Thomas Jens of Max Planck Institute for Extraterrestrial Physics in Garching, Germany and Karl Gebhardt from University of Texas has estimated the mass of the black hole as equivalent to 6.4 whopping billion suns.
New Scientist says this may be a good thing because:
M87's black hole, when viewed from Earth, would be the same apparent size as the nearer black hole at the centre of the Milky Way. This puts M87's hole within reach of radio astronomy techniques that measure a black hole directly, by tracing its dark silhouette against the glow of surrounding gas.
