Using the light from 67 extremely distant quasars astronomers have calculated that cosmic dawn, the period in which the first stars began to form, ended 1.1 billion years ago

Having telescopes up in space has dramatically improved our understanding of the Universe. Freed from the noise, both visual and otherwise, caused by humans and their activities here on Earth, these machines gave us a new dimension of how things work out there in the great void.

Astronomers announced this month that a new deep-field survey called JADES will be carried out with the James Webb Space Telescope, Hubble’s much-anticipated successor. The Webb is due to launch later this year.
The Hubble Ultra Deep Field (in its eXtreme version) is the deepest view of the universe yet obtained … and will be, until JADES takes over. It stretches approximately 13 billion light-years and includes approximately 10,000 galaxies. It took 11.3 days for the Hubble Space Telescope to collect these ancient photons.

Oldest, most distant galaxy till date discovered; know details
From previous studies, the galaxy GN-z11 seems to be the farthest detectable galaxy from us, at 13.4 billion light-years. The galaxy GN-z11, which scientists think could be the farthest and oldest galaxy ever observed, superimposed on an image from the COODS-North survey (Image: NASA)

Astronomers from the University of Tokyo have discovered what they believe is the oldest, most distant galaxy till date. Called GN-z11, the galaxy is 13.4 billion light-years or 134 nonillion kilometers away from us.
The galaxy has been discovered by an international team of astronomers led by Nobunari Kashikawa, a professor at the department of astronomy at the varsity.
