New images from NASA's James Webb Space Telescope show what may be among the earliest galaxies ever observed.

CEERS researchers are studying how some of the earliest galaxies formed when the universe was less than 5 percent of its current age, during a period known as reionization, and how galaxies evolved between then and today.

If the finding is confirmed, it would be one of the earliest galaxies ever observed, and its presence would indicate that galaxies started forming much earlier than many astronomers previously thought.

The unprecedentedly sharp images reveal a flurry of complex galaxies evolving over time-some elegantly mature pinwheels, others blobby toddlers, still others gauzy swirls of do-si-doing neighbors.

Kartaltepe has multiple leading roles in the survey, focusing on morphology-measuring the shapes and sizes of galaxies and studying how their structures evolved-and setting up and analyzing spectroscopic observations of distant galaxies using the NIRSpec instrument.

Much more imaging data will be collected in December, along with spectroscopic measurements of hundreds of distant galaxies.

Over the course of 218 observing hours, COSMOS-Web will conduct an ambitious survey of half a million galaxies with multi-band, high-resolution near infrared imaging and an unprecedented 32,000 galaxies in mid infrared.

NASA's James Webb Space Telescope has peered into the chaos of the Cartwheel Galaxy, revealing new details about star formation and the galaxy's central black hole.

Webb's powerful infrared gaze produced this detailed image of the Cartwheel and two smaller companion galaxies against a backdrop of many other galaxies.

This image provides a new view of how the Cartwheel Galaxy has changed over billions of years.
