Astronomers devise a way to see through the 'fog' of the early universe

Daily Mail  

Astronomers have devised a new way to 'see' through the fog of the early universe so they can detect light from the very first stars and galaxies. But while Webb looks at wavelengths in infrared, the Earth-based next-generation SKA telescope – due to be completed by the end of the decade – will study the early universe through radio waves. Birth of the cosmos: Astronomers have developed a new way to 'see' through the fog of the early universe so they can detect light from the very first stars and galaxies. Bands of electromagnetic waves are: Gamma radiation X-ray radiation Ultraviolet radiation Visible light Infrared radiation Microwave radiation Radio waves Of the most famous current and forthcoming telescopes, James Webb looks at the universe in the infrared, Hubble in ultraviolet or visible light and the next-generation Square Kilometre Array will study radio waves.

An alien signal? What 40 Earth antennas and Webb Telescope found in space

India Today  

In a groundbreaking achievement for astronomy, researchers have successfully detected emissions from one of the most distant galaxies known, located over 13 billion light-years away. Jorge Zavala, an astronomer at the East Asian ALMA Regional Center, explained, “We pointed the more than forty 12-m antennas of ALMA and the 6.5-m JWST at a seemingly empty sky position for several hours …

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 …

While the James Webb Space Telescope is a secular achievement, the pioneering telescope nevertheless conjured up that Biblical imagery of "Let there be light!" "If you took the whole universe and shrunk it down to a two hour movie, you are seeing the first five minutes of the movie," Kevin Hainline, a lead author of the study and an assistant …

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 …

Astronomers detect for first time light coming from the very first stars of our universe

Firstpost  

A team of astronomers including an Indian graduate student Nivedita Mahesh from Arizona State University have discovered for the first time signals from “cosmic dawn” — the moment when the universe’s earliest stars emerged, making a significant breakthrough in our understanding of the evolution of cosmos. When the universe was formed in the Big Bang event 13.8 billion years ago …

Scientists detect ‘fingerprint’ of first light ever in the universe

CNN  

CNN — Scientists have detected traces of the earliest light in the universe thought to emanate from the first stars formed after the Big Bang, billions of years ago. The new report, published in Nature on February 28, said researchers found the “fingerprint” of the universe’s first light as background radiation left on hydrogen. “This is the first time we’ve …

The researchers used the Hubble space telescope to find the galaxy and confirmed its age and distance with instruments at the Keck Observatory in Hawaii. Astronomers have discovered a faint, incredibly distant galaxy, about 13.1 billion years in the past, just about 700 million years after the Big Bang. “Other most distant objects are extremely bright and probably rare compared …
