London: Astronomers have for the first time have discovered the universe's most ancient spiral galaxy yet, a cosmic structure that dates back roughly 10.7 billion years, a new study reveals.

According to researchers, they have discovered it using NASA’s Hubble Space Telescope and it has come as surprise for astronomers.    

Other galaxies from such early epochs are clumpy and irregular, not strikingly symmetrical like the newfound spiral, which broadly resembles our own Milky Way.

This distant spiral galaxy is being observed as it existed roughly three billion years after the Big Bang, and light from this part of the universe has been travelling to Earth for about 10.7 billion years.

Among various types of galaxies in today''s universe, spiral galaxies like our own Milky Way, which are rotating disks of stars and gas in which new stars form, and elliptical galaxies, which include older, redder stars moving in random directions.
