A new study has revealed that the first image taken by the James Webb Space Telescope reveals some of the oldest stars and galaxies in the universe, including diamond-like ones.

It was Webb .’s first great scene Released by President Joe Biden on July 11 It’s “the deepest and most accurate infrared image of the distant universe to date,” according to NASA.

Webb’s first image shows SMACS 0723, where a huge group of galaxy clusters acts as a magnifying glass for the things behind them.

This is called a gravitational lensing, and it has created the first deep-field web spectacle involving incredibly ancient and faint galaxies. Deep field observations are extended observations of areas of the sky that can reveal faint objects.

Some of these distant galaxies and star clusters have never been seen before. The galaxy cluster appears as it appeared 4.6 billion years ago.

Now, researchers have performed Webb’s first deep-field analysis and discovered the most distant globular clusters ever. These clusters are dense clusters containing millions of stars, some of which may be the oldest and most ancient stars in the universe. A detailed study of the results was published Thursday in Letters from astrophysics journals.

Lamia Molla, study co-author and Dunlap Fellow at the Dunlap Institute for Astronomy and Astrophysics at the University of Toronto, said in a statement.

“This discovery in Webb’s first deep field already provides a detailed look at the first stage of star formation, confirming the amazing power of JWST.”

An important feature of the deep field is called the Sparkler Galaxy because it appears to be surrounded by bright red and yellow dots. The galaxy is located nine billion light-years away.

The flares could be small clusters where stars were actively forming only three billion years after the Big Bang, or they could be ancient globular clusters of stars from the early days of galaxy formation.

The team analyzed 12 flares and determined that five of them are among the oldest globular clusters ever found.

Karthik J. Iyer, co-lead author of the study and a Dunlap Fellow at the Dunlap Institute for Astronomy and Astrophysics at the University of Toronto, said in the statement.

“Because we can observe flares at a wide variety of wavelengths, we can model them and better understand their physical properties, such as their age and the number of stars they contain. JWST will stimulate more science and research for similar objects.”

Webb’s sensitivity and subtlety of light casts unprecedented aspects of the universe, such as the clusters that surround the Sparkler Galaxy.

“These newly identified clusters formed close to the first time stars formed,” Mola said. “We’re watching Sparkler as it was nine billion years ago, when the universe was only four and a half billion years old, looking back at something that happened a long time ago. Think of it like guessing a person’s age based on their appearance—it’s easy to tell the difference between children who They are between 5 and 10 years old, but it’s hard to tell the difference between 50 and 55 people.”
