Scientists Find Light From the First Ever Stars Formed Billions of Years Ago in the Universe

News 18  

Before the beginning of space and time, there was nothing. Interestingly, we can still see the initial starlight from the cosmic dawn that has been travelling to us for billions of years, if we look far enough. So, when we look at faraway objects in space using our powerful telescopes, we are actually looking at the light that was released way before it reaches our telescope, thanks to the limited speed of light – 3,00,000 kilometres per second. For example, if we want to look a million year back in time, we need to look at the light coming from an object that is a million light-years away from us. Now, scientists expect that a new and more powerful NASA’s James Webb Space Telescope that will launch this year will let us have a clearer view of the first galaxies and take us farther back in time.

Earliest-known galaxy, spotted by Webb telescope, is a beacon to cosmic dawn

The Hindu  

NASA's James Webb Space Telescope has spotted the earliest-known galaxy, one that is surprisingly bright and big considering it formed during the universe's infancy— at only 2% its current age. Webb, which by peering across vast cosmic distances is looking way back in time, observed the galaxy as it existed about 290 million years after the Big Bang event that …

Astronomers discover oldest ‘dead’ galaxy ever observed

Live Mint  

Astronomers have spotted a galaxy that suddenly stopped forming new stars more than 13 billion years ago. An international team of astronomers led by the University of Cambridge used the James Webb Space Telescope to spot a ‘dead’ galaxy that formed when the universe was just 700 million years old, the oldest such galaxy ever observed. Although astronomers have observed …

What ended the ‘dark ages’ in the early universe? Webb telescope finds clue

The Hindu  

About 400,000 years after the Big Bang, the cosmos was a very dark place. However, as more and more stars formed, they produced enough light to burn away the fog by “reionising” the gas – creating the transparent universe dotted with brilliant points of light we see today. The second camp thinks we are better off ignoring the giant galaxies …

Space telescope uncovers massive galaxies near cosmic dawn

The Hindu  

Astronomers have discovered what appear to be massive galaxies dating back to within 600 million years of the Big Bang, suggesting the early universe may have had a stellar fast-track that produced these “monsters.” While the new James Webb Space Telescope has spotted even older galaxies, dating to within a mere 300 million years of the beginning of the universe, …
