A Precise Test Of Einstein's General Relativity Outside The Milky Way

ESO 325-G004

Using the MUSE instrument on ESO's VLT , a team led by Thomas Collett from the University of Portsmouth in the UK first calculated the mass of ESO 325-G004 by measuring the movement of stars within this nearby elliptical galaxy .
