The James Webb Telescope has just started sending out stunning images from space — and now the telescope has apparently discovered the oldest galaxy yet, he writes new world.
It is estimated that the galaxy called GLASS-z13 formed just 300 million years after the Big Bang. That makes it 100 million years older than the oldest galaxy to date, GN-z11, discovered by the Hubble telescope.
discovery Performed by Rohan Naidoo and colleagues at the Harvard-Smithsonian Center for Astrophysics. At the same time, they discovered another ancient galaxy like GN-z11: GLASS-z11. The latter appears to form a plate-like formation due to its rotation.
Each of the newly discovered galaxies is small. GLASS-z13 spans just 1,600 light-years, while GLASS-z11 is thought to span 2,300 light-years. It can be compared to the Milky Way, which is 100,000 light years in diameter.
Galaxies are found by closely studying the first Webb Telescope’s deep field image, which reveals thousands of galaxies.
More work is now pending to confirm the history of the two newly discovered galaxies. And only Webb Telescope can provide the necessary information.
Astronomers had previously expected that the extremely powerful James Webb Telescope would enable the discovery of the first galaxies. The hope is to discover older galaxies and stars, which arose about 200 million years after the Big Bang.
The timing of the formation of the first stars and galaxies is among the remaining questions to understand the origin of the universe.
