The James Webb Telescope is the closest we’ve come to a time machine. NASA’s most powerful space telescope continues to amaze scientists and people everywhere with surprising findings.
Astronomers used the James Webb Space Telescope to peer into the dusty clouds of a distant star-forming galaxy to study its composition in great detail.
NASA’s billion-dollar observatory has discovered the star composition of one of the oldest known galaxies in the universe. The ‘GN20’ galaxy is 12 billion light-years away. It is one of the most spectacular, dusty star-forming galaxies ever discovered.

The galaxy’s recent formation, 1.5 billion years after the big bang, is what makes it so fascinating. It is located in a region of space known as the protocluster or galaxy hyperdensity.
Astronomers are interested in this region of space because the galaxies in this cluster eventually come together to form a vast collection known as a galactic cluster.
The image you see is from a time when the universe was just 1.5 billion years old, and it is currently 13.5 million years old. The ancient galaxy is forming stars every year at a rate of about 1,860 times the mass of the Sun.
Astronomers working under the direction of Luis Colina of the Spanish Astrobiology Center used Mid-Infrared Instrument (MIRI) images of GN20 taken between November 23 and 24, 2022, to infer about GN20’s structural properties.
They discovered that the galaxy is surrounded by dense molecular gas about 46,000 light-years in diameter and flattened into a massive rotating disk.

The 45,600 light-year-wide galaxy is composed of a diffuse envelope of gas that surrounds a concentrated, sparkling nucleus of tightly grouped stars. The measurements also showed that the core (nucleus) is about 2,600 light-years across, while the gaseous envelope is about 23,000 light-years across.
