. By looking at those galaxies in ultraviolet light, scientists can discover what chemicals lie inside those galaxies — information that is key to understanding how galaxies form and evolve. But there's a problem with this method: That primordial ultraviolet light gets absorbed before it can reach us.
But scientists can look at many, many galaxies that are just a little younger, 11 billion years old. And that's what astronomers have done with theHubble Space Telescope's largest-ever infrared image peers back 10 billion years The image is part of a recent survey called UVCANDELS. Over about 10 days of observational time, Hubble imaged about 140,000 galaxies. Some of them are visible in the newly released image — numerous types of galaxies, seen from a range of angles.
UVCANDELS provides unique"insight into ongoing star formation in galaxies both near and far," said Xin Wang, an astronomer at Caltech who presented the results June 14 at the American Astronomical Society conference in California.
