And the longer the researchers look at the deep field, the more weird and wonderful things they'll turn up.Supports Xbox Play Anywhere: yours to play on both Xbox One and Windows 10 PC at no additional cost. So, some of the red and orange galaxies in this image are actually ancient background galaxies whose light has been redshifted on the way to JWST's lens.Įstimating the ages of the thousands of objects peppered throughout this image is just one of the exciting challenges awaiting scientists. Basically, as light travels across the vast and expanding universe, its wavelength gradually increases with distance, turning redder and redder over time. However, a galaxy's color can also be altered by its distance from the telescope, thanks to a phenomenon called redshift. ![]() Generally, the bluer galaxies in this image are younger spiral galaxies, while the redder galaxies are old, dead elliptical galaxies. The massive blue stars die off first, and you're left with the old red stars." "They've already formed all of their stars. "Elliptical galaxies are kind of dead," Gaudi said. (Image credit: NASA, ESA, CSA, and STScI) Orange elliptical galaxies like this one are predominantly made of old, dead stars. Look a bit above and to the left of that spiral, and you'll see the other dominant type of galaxy in our local universe: a fiery orange elliptical galaxy. Spiral galaxies are active, star-forming galaxies, Gaudi said, and they tend to be filled with hotter, younger stars that glow in whitish-bluish light. Look right of the bright star at the image's center and you'll see a perfect spiral galaxy, just like our own Milky Way. ![]() These galaxies come in two major varieties. Almost everything else you can see is a galaxy or cluster of galaxies, Gaudi said. In general, the big, bright, six-pointed objects in the foreground of the image are stars. But, as this image shows, the powerful telescope can't look back in time without thousands upon thousands of younger, closer galaxies photo-bombing the frame. Studying the oldest light in the universe is one of NASA's key objectives for the JWST. Looks just like home! (Image credit: NASA, ESA, CSA, and STScI) Despite their large and looming appearance, the galaxies are in reality more than 13 billion light-years away, Gaudi said - potentially making them some of the oldest observable galaxies in the universe.Ī perfect spiral galaxy swirls off to the side of the central galaxy cluster. They seem incredibly long - longer even than the massive central cluster - because their light is being magnified so dramatically. If you imagine the center of this image as a clock, you can clearly see two such background galaxies sitting between 2 and 3 o'clock, and 7 and 9 o'clock, respectively.īoth of these galaxies appear as bright, orange, curving lines that wrap around the central galaxy cluster. Like the cosmic combination of a magnifying glass and a funhouse mirror, gravitational lenses both warp and magnify the light of background galaxies. Once their light hits the cluster, the cluster mass bends that light and creates what's known as a gravitational lens." "These are background galaxies that are sitting behind the foreground cluster. "Probably the next thing that will catch your eye are these weird, worm-shaped arcs that are sort of emanating from the center of the image," Gaudi said. That leads to the next key feature of the JWST deep field image - gravitational lensing. Mass is precisely what makes SMACS 0723 such a good target this galaxy cluster is so massive, it warps the light of stars and galaxies located billions of light-years behind it (relative to our view from Earth). ![]() These are ancient galaxies situated billions of light-years behind the foreground galaxy cluster, warped and magnified by the cluster's mass. Long, worm-like arcs of orange light swirl around the galaxy cluster's edges. ![]()
