James Webb reveals a barred spiral galaxy shockingly early in the Universe

A surprisingly mature barred spiral galaxy was already taking shape when the Universe was only 2 billion years old. An unsharp mask overlaid onto the F200W, F277W, and F356W filter composition.

A research team led by Daniel Ivanov, a physics and astronomy graduate student in the Kenneth P. Dietrich School of Arts and Sciences at Pitt, has identified a strong candidate for one of the earliest known spiral galaxies with a stellar bar. These bright, elongated structures can strongly influence how galaxies grow and change over time. The Milky Way itself contains a stellar bar at its center. The newly studied galaxy, named COSMOS-74706, appears to have existed about 11.5 billion years ago. By analyzing its light, researchers were able to determine its place in cosmic history and narrow down when barred structures may have first formed in the universe. "This galaxy was
