The universe is filled with stars, planets, stable structures, galaxies, clusters, black holes, and what not. As the view from our eyes and telescopes is limited, we are dependant on the outer space telescopes like the Hubble Space Telescope. Today, scientists observing the tiny star cluster in Milky Way galaxy using the Hubble Space Telescope made an exciting discovery, which is of a new galaxy. Scientists spotted a new galaxy, that is lying beside the cluster scientists studying with the Hubble telescope.
Scientists were studying the cluster named NGC 6752, which is 13,000 light years away from our planet. Behind that cluster, lying was the Bedin 1, a new galaxy that is 30-million light years away from the earth. Scientists were confused Bedin 1 with the NGC 6752, but after calculating the brightness and temperatures of stars, they confirmed it as Bedin 1.
The Debin 1 is way too smaller than our galaxy and way too dimmer than ours. That’s why it was hidden behind the star cluster, and we were not able to spot it or differentiate it from a star cluster. Debin 1 is a spherical galaxy and commonly known as a spheroidal galaxy. It’s now a part of 36 such known galaxies in the universe, in which our Milky Way and neighboring Andromeda come as well. Debin 1 is expected to be the 13 billion years old, which is the living fossil of our universe and the calculated age of the world is 13.8 billion years. Such accidental discoveries are rare, and we might not see such discoveries in the coming years. But to help accelerate the study of such objects, NASA will launch the Wide-Field Infrared Survey Telescope, or WFIRST next year. The WFIRST will have the 100 times more field of View than Hubble telescope and will effectively replace the same.
