Together with the Hubble Space Telescope, astronomers have discovered a dwarf galaxy in a globular cluster which is only 30 million light-years away.
The team used the NASA/ ESA (European Space Agency) telescope to examine white dwarf stars over the globular cluster NGC 6752.
From the outer fringes of this area observed with Hubble’s camera, a streamlined collection of stars was visible.
Following a careful analysis of the brightnesses and temperatures, the astronomers reasoned that these stars did not belong to the cluster – that is part of the Milky Way – but rather they’re millions of light-years more remote.
The recently discovered cosmic neighbour, nicknamed Bedin 1 from the astronomers, is a modestly sized, elongated galaxy, the study said.
It measures only around 3, 000 light-years at its best scope – a fraction of the size of the Milky Way. Not only is it tiny, but it is also incredibly dimmed.
These properties led astronomers to classify it as a dwarf spheroidal galaxy.
Dwarf spheroidal galaxies are characterized by their small size, low-luminosity, lack of dust and old stellar populations
The international team of astronomers that carried out this research includes researchers from University of California Los Angeles, University of Bonn in Germany and Universite de Montreal in Canada, among others.
