New Delhi: The US space agency, NASA has released a beautiful image of NGC 4789A, a dwarf irregular galaxy in the constellation of Coma Berenices.
The image which was taken by NASA's Hubble Space telescope, has revealed numerous other galaxies, far more distant, that appear as fuzzy shapes spread across the it
According to NASA, it certainly lives up to its name, the stars that call this galaxy home are smeared out across the sky in an apparently disorderly and irregular jumble, giving NGC 4789A a far more subtle and abstract appearance than its glitzy spiral and elliptical cousins.
The stars may look as if they have been randomly sprinkled on the sky, but they are all held together by gravity, as reported.
The colors in the image have been deliberately exaggerated to emphasize the mix of blue and red stars. The blue stars are bright, hot and massive stars that have formed relatively recently, whereas the red stars are much older. The presence of both tells us that stars have been forming in this galaxy throughout its history.
NGC 4789A is relatively close to us with just a distance of just over 14 million light-years away and allows us to see many of the individual stars within its bounds.
