NASA’s James Webb Space Telescope has made a significant discovery by spotting some of the most massive galaxies in the universe, which existed just a few hundred million years after the Big Bang.
According to the latest findings, these galaxies are estimated to be 10 to 100 times larger than our Milky Way and are located at a distance of more than 13 billion light-years away.
These massive galaxies are believed to have formed during the early stages of the universe, when the cosmic microwave background radiation was still cooling. The radiation cooled enough for gravity to take hold, causing gas clouds to collapse and form the first galaxies.
The discovery is significant because it helps astronomers to understand the formation and evolution of galaxies in the early universe, and sheds light on how the universe grew and evolved into what it is today.
The Webb telescope, which is set to launch in October 2021, will continue to explore the cosmos and capture breathtaking images of the universe. The telescope is expected to provide unprecedented views of the earliest stages of the universe, and help scientists to better understand the history of the universe, including the formation of galaxies, stars, and planets.
Overall, the discovery of these massive galaxies is a remarkable achievement, and is a testament to the power and capabilities of NASA’s Webb telescope. With this discovery, we can expect even more exciting discoveries in the coming years as the telescope continues to explore the vast expanse of the universe.
