"First-ever 3D map reveals asymmetrical M87 galaxy and mysterious black hole jet"

Astronomers have created a 3D map of Messier 87 (M87), one of the largest known elliptical galaxies, using data from the W.M. Keck Observatory and the Hubble Space Telescope. The map revealed that M87 has a triaxial shape, similar to a potato, and is not symmetrical. The team estimated that the supermassive black hole at the center of M87 is about 5.4 billion times more massive than the sun. The map and new estimation of the black hole's mass could help researchers calculate its rotation speed.
