james Webb Telescope Peers Into Cosmic dawn, Reveals earliest Galaxies
The James Webb Space Telescope has achieved a new milestone, capturing the most detailed image to date of a single area in the distant universe. This groundbreaking observation unveils galaxies in their formative stages, offering unprecedented insights into the universe’s infancy.
Key Findings
- deepest Image: The image represents the deepest view ever obtained by the James Webb Telescope of a single target.
- Galaxies in Formation: It reveals galaxies as they appeared billions of years ago, during the universe’s early stages.
- Gravitational Lensing: The observation leverages the effect of gravitational lensing to magnify and reveal these distant objects.
The Power of Gravitational Lensing
at the heart of the image lies Abell S1063, a massive cluster of galaxies situated 4.5 billion light-years from Earth. These colossal celestial structures act as cosmic magnifying glasses, bending the light from objects located far behind them. This phenomenon,known as gravitational lensing,allows scientists to observe galaxies and stars that formed in the universe’s first billion years.
The French research agency stated, Thanks to the effect of gravitational lens, these observations reveal the first galaxies and stars that formed during the first billions of years in the history of the universe.
A Glimpse into Cosmic Dawn
The deformed arches
swirling around Abell S1063 are of particular interest to researchers, according to the European Space Agency (ESA). By observing these distant regions, scientists are peering back in time, hoping to unravel the mysteries of how the first galaxies came into existence during the cosmic dawn, a period when the universe was only a few million years old.
Unprecedented Observation time
The creation of this image required an unprecedented 120 hours of observation, marking the longest period the James Webb Telescope has focused on a single target. According to ESA, it is also the deepest image obtained from James Webb about a single target.
FAQ
- what is the James Webb Space Telescope?
