James Webb Telescope Finds Galaxies Nearly as Old as the Early Universe
NASA’s James Webb Space Telescope has revealed early galaxies that appear almost as old as the universe itself. By analyzing 31 galaxies at high redshift, researchers estimated stellar ages of around 600 million years—close to the universe’s age at that epoch. One galaxy may even seem older than the universe, posing a potential challenge to t...

James Webb Telescope Discovers Most Distant Galaxy From Just 300 Million Years After the Big Bang
The James Webb Space Telescope has discovered the most distant galaxy ever observed, JADES-GS-z14-0, seen as it existed just 300 million years after the Big Bang. Its unexpected brightness and chemical complexity suggest rapid early star formation, challenging long-standing theories about how the first galaxies evolved in the early universe.

NASA's James Webb Telescope Reveals Helix Nebula In Stunning Detail, Showing How Dying Stars Seed Future Planets
Previous Spitzer studies have indicated the formation of complex molecules in the Helix Nebula.

JWST Uncovers the Origins of the Universe’s First Supermassive Black Holes
James Webb Space Telescope observations reveal that the earliest supermassive black holes formed from massive gas clouds collapsing directly into heavy seeds. This process bypassed normal star formation, allowing black holes to reach millions of solar masses within just 200–500 million years after the Big Bang, solving a long-standing cosmic myst...

James Webb Helps Astronomers Chart the Universe’s Hidden Dark Matter
Astronomers have created the sharpest map yet of dark matter using deep observations from NASA’s James Webb Space Telescope. By analysing the gravitational distortion of hundreds of thousands of distant galaxies, the team traced invisible dark matter across a large region of the sky. The results confirm that dark matter forms the scaffolding arou...

James Webb Watches a Young Star Bake Crystals for Future Planets
Using NASA’s James Webb Space Telescope, astronomers have observed a young star in the Serpens Nebula forging crystalline silicates during powerful outbursts. The findings explain how heat-formed minerals can end up in cold cometary regions and planet-forming disks, shedding light on early stages of planet formation.

NASA's James Webb Space Telescope Might Have Spotted Hidden Supermassive Black Holes
Mysterious “little red dots” spotted by the James Webb Space Telescope may not be tiny galaxies after all. A new study suggests they are supermassive black holes wrapped in dense gas and dust, perfectly disguised in the early universe and shining intensely in infrared light.

James Webb Telescope Finds Rare Cosmic Dust in One of the Universe’s Most Primitive Galaxies
A breakthrough has been made in the area of astrophysics as NASA’s James Webb Telescope has spotted two rare kinds of dust in the Early-Universe Analog.

JWST Reveals Powerful Winds and Dense Atmosphere on Scorching Exoplanet TOI-561b
Astronomers using NASA’s James Webb Space Telescope have found compelling evidence that TOI-561b, an ultra-hot rocky exoplanet orbiting its star every 11 hours, still retains a dense atmosphere. Temperatures measured on both its day and night sides are far lower than expected for a bare rock, implying powerful winds and efficient heat transport. ...
