Using the Hubble Space Telescope, astronomers have Found a dwarf galaxy in a globular cluster That’s only 30 million light-years away.
The team employed the NASA/ ESA (European Space Agency) telescope to study white dwarf stars within the globular cluster NGC 6752.
The aim of the observations was to use these stars to measure the age of the globular cluster, but in the process they made an unexpected discovery, according to the study published in the journal Monthly Notices of the Royal Astronomical Society: Letters.
From the outer fringes of the region observed with Hubble’s camera, a compact selection of celebrities was observable.
Following a careful analysis of the brightnesses and temperatures, the astronomers reasoned that these celebrities did not belong to the bunch – which is part of the Milky Way – but instead they are countless light-years more remote.
The newly discovered cosmic neighbor, filmed Bedin 1 by the astronomers, is a modestly sized, elongated galaxy, the analysis said.
It measures just around 3, 000 light-years in its greatest extent – a fraction of the size of the Milky Way. Not only is it tiny, but it is also incredibly faint.
These properties led astronomers to classify it as a dwarf spheroidal galaxy.
Dwarf spheroidal galaxies are defined by their small dimensions, low-luminosity, lack of dust and old stellar populations
