6 galaxies have been discovered thanks to NASA’s Webb Telescope. “They are old and should not be around.”

NASA’s James Webb Space Telescope identifies six “massive” galaxies that are too old to exist. It is a discovery that “pushes the boundaries of our understanding of cosmology.” NASA’s new Super Space Telescope is built to look into the dawn of time and give us clues about how the universe came to be.

What happened

The new super telescope is built to go back to the dawn of time and give us clues about how the universe came to be. In less than a year, James Webb wowed us with stunning images, but now he’s challenging our understanding of the origins of galaxies.

In fact, the $10 billion observatory has spotted six “massive” galaxies in the early universe that are far too old to exist.

“These objects are much larger than expected,” he said. Joel LegaAssistant professor of astronomy and astrophysics Pennsylvania state who then explains “We expected to find only young, young, newborn galaxies at this time, but we have discovered mature galaxies like our own in what was previously considered the dawn of the universe.”

Researchers opinion

The researchers said their new discovery “transcends the limits of our understanding of cosmology” and suggests that The galaxies have grown massively faster than expected at the beginning of the history of the universe.

“We’ve informally called these beings cosmos breakers, and so far they’ve lived up to their name,” Lega said.

He added that the galaxies were so massive that they “grazed” them 99% of cosmic models.

to take into accounthigh massmeans that these models must change, or astronomers will have to change their basic understanding of how galaxies formed in the early universe.

This means that they were born Small clouds of stars and dust that gradually enlarged over time.

How then was the universe born?

Whichever path the scientists take, Lega said it will require a fundamental rethink How was the universe born.

“Revealing that the formation of massive galaxies began very early in the history of the universe challenges what many of us believed solid sciencesaid Lega.

He said the international team of researchers had “no idea what we were going to find” when they examined Webb’s first batch of data about the early universe. We’ve found something so unexpected that it’s causing problems for science. It challenges the whole picture of the formation of the first galaxies, Lega added.

The new findings show that the six galaxies were as mature as our own Milky Way when the universe was just me3% of his current ageabout 500-700 million years after the Big Bang.

Webb is able to go back in time to 13.5 billion years – about two million years after the formation of the universe – because it contains infrared sensors that can detect light emitted by the oldest stars and galaxies.
