Spiral Galaxy discovered |
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.
