NASA’s James Webb Space Telescope captures the oldest galaxy ever

NASA’s James Webb Space Telescope (JSWT) has yet again achieved an amazing feat, capturing the oldest galaxy ever seen. The world’s most expensive telescope has broken its own previous record by finding a galaxy that is 100 million years older than its last one.

Galaxy GLASS-z13
Just last week, the James Webb Space Telescope shared an image of a galaxy called GLASS-z13, the ‘then' oldest galaxy which was estimated to be just 300 million years after the Big Bang. If that was not amazing enough, the telescope has found yet another galaxy that is even older! (Dr. James O'Donoghue/Twitter)

JWST has discovered a star cluster which has been named CEERS-93316. The galaxy found is estimated to have formed just around 235 million years after the Big Bang. In the span of a week, the telescope has broken its own record. (NASA)

Even more amazing is the fact that the discovery of this galaxy was an accident! Researchers from the University of Edinburgh, Scotland, began compiling the images sent by JWST to find a correlation between the luminosity of galaxies deemed as old. They accidently stumbled upon this marvelous discovery. (AFP)

Callum Donnan, an astrophysics PhD student in the university's Institute for Astronomy told BBC, “We're using a telescope that was designed to do precisely this kind of thing, and it's amazing.” The oldest nature of a galaxy is measured in terms of Redshift, which is the measure of light into the shorter reddish wavelengths to gain an idea of its distance and age. CEERS-93316 has a redshift of 1.67 making it the oldest galaxy ever spotted. (AP)

However, it is to be noted that the finding was published in a study posted on arXiv. It is yet to be reviewed by peers, so it could be possible that this fact could be disputed. Until then, this can be considered James Webb Space Telescope’s crowning achievement till date. (AFP)
