Space is full of unidentified and undiscovered objects, galaxies, and what not. And now the James Webb Space Telescope has created history by finding a galaxy that existed 13.5 billion years ago. The galaxy is known as GLASS-z13 and it is the oldest galaxy in the universe seen by man. A report by AFP quoted a scientist who analysed the data as saying, "Just a week after its first images were shown to the world, the James Webb Space Telescope may have found a galaxy that existed 13.5 billion years ago."
The galaxy GLASS-z13 dates back to just 300 million years after the Big Bang, which is about 100 million years earlier than anything previously identified, Rohan Naidu of the Harvard Center for Astrophysics told AFP. "We're potentially looking at the most distant starlight that anyone has ever seen," he said.
Dr. James O'Donoghue, planetary scientist, science communicator and amateur animator, who previously worked with NASA, and now at Japan Aerospace Exploration Agency, tweeted about the Galaxy. "JWST has potentially smashed records, spotting a galaxy which existed when the universe was a mere 300 million years old! The light from GLASS-z13 took 13.4 billion years to hit us, but the distance between us is now 33 billion light years due to the expansion of the universe!," the tweet read. The tweet was further retweeted by NASA's chief scientist Thomas Zurbuchen.
