Liller 1
Liller 1 is a globular cluster close to the centre of the Milky Way, only 3,200 light years from the centre. It is heavily obscured by dust, being close to the galactic plane. Liller 1 is just under 30,000 light years from Earth. It has a mass of around 1.5 million solar masses. It has the highest level of emission of gamma rays of any globular cluster. This may be due to a large number of stellar collisions and pulsars.
The globular cluster contains the rapid burster called MXB 1730-335.
