#JWST has revealed the whipped-up dust from the birth of a star—and a shining background galaxy—more clearly than ever before.
Stars are born here. See the Carina Nebula up close and learn the science behind the beauty:

From blurry to breathtaking: Comparing three views of the Carina Nebula. La Silla, Hubble, and James Webb show this cosmic landscape in ever greater clarity, illustrating how advances in telescope technology are transforming our vision of the universe and revealing its hidden structures.
From Voyager 2’s smooth blue-green view in 1986 to Webb’s breathtaking 2023 image, our vision of Uranus has transformed. Keck (2002) revealed faint rings, Hubble (2022) showed brighter tones and weather patterns, and Webb unveiled glowing rings and a luminous atmosphere.
Giant, free-floating planets may form their own planetary systems
New research from the University of St Andrews has found that giant free floating planets have the potential to form their own miniature planetary systems without the need for a star.

A group led by Fujimoto-san et al have uncovered a primordial galaxy, just 930 million years after the Big Bang (z=6.072). The galaxy is composed of at least 15 dense, star-forming clumps embedded within a rotating disk like a "Cosmic Grape". These clumps, with sizes ranging from 10 to 60 parsecs, dominate 70% of the galaxy's UV light, and are reshaping our understanding of early galactic structure formation. More than 100 hours of joint ALMA and JWST observations were made, amplified by gravitational lensing, making this one of the most studies early galaxies.

Is there a planet around Alpha Centauri A? Maybe.
Alpha Centauri is a triple star system, with two sun-like stars, Alpha Centauri A and Alpha Centauri B, and a small red dwarf star, Proxima Centauri. There are three confirmed planets around Proxima Centauri.
Researchers used JWST to look at Alpha Cen A, following up on a possible detection of a planet around the star in 2019 by the ground-based VLT.
The team found a promising candidate in August 2024, but didn't see anything in February 2025 and April 2025. It's possible that the planet moved between observations to a position that would not be observable by JWST.
Models suggest that if the planet is real, it would be about the mass of Saturn orbiting in an elliptical path varying between 1-2 AU.

JWST MIRI image of Arp 107, also known as UGC 5984.
In this pair of interacting galaxies, only the one-armed spiral glows brightly in mid-infrared light. Young, forming stars, surrounded by dusty silicates and soot-like molecules known as polycyclic aromatic hydrocarbons, are shown in blue.

Dying stars wreathed in a vast spirals of glowing dust, like a snake eating its own tail. They have been named Apep, after the Egyptian god of destruction.

Cat's Paw Nebula from Webb Space Telescope
At 5,700 light years distant, Cat's Paw is an emission nebula within a larger molecular cloud. Alternatively known as the Bear Claw Nebula and cataloged as NGC 6334, stars nearly ten times the mass of our Sun have been born there in only the past few million years. Pictured here is a recently released image of the Cat's Paw taken in infrared light by the James Webb Space Telescope.
