Carina nebula Photo by NASA/ESA/CSA/STScI Sparkling clusters of millions of stars and starbursts can be seen around the outside of the quintet, and the image also captures huge shock waves as one of the galaxies smashes through a cluster. While this group of galaxies has been pictured before, JWST achieves more detail than before. This grouping of galaxies being so near to each other allows scientists to witness their merging to get a better understanding of how galaxies evolve. The other galaxies are around 290 million light-years away. While it looks like all the galaxies are the same distance away, one of them (NGC 7320) is actually much nearer at a distance of around 40 million light-years away. Originally identified all the way back in 1877 by Édouard Stephan, Stephan's Quintet is made up of five interacting galaxies that have the appearance of almost touching each other. Stephan's Quintet Photo by NASA/ESA/CSA/STScI - © NASA, ESA, CSA, and STScI Unlike the one on the left which was taken using an infrared camera, this is studied through the Mid-Infrared Instrument (MIRI) which helps astronomers capture details which were previously hidden in dust. The image on the right is of the same Southern Ring Nebula. This dying star is actively expelling gas and dust which is creating the orange almost foam-like substances. At the centre of the nebula is a dying star (seen in the blue section of the image on the left). These stunning images produced by the JWST is of the Southern Ring Nebula.

The planet is located roughly 1,120 light-years from us, and the information in this graph shows water in the form of vapour, hazes and evidence of clouds. It's a light graph that reveals key information about the atmospheric composition of WASP-96b, a hot giant exoplanet with a mass similar to that of Saturn. While the other images in this first group were all photos taken with the JWST, this image instead looked to give us an insight into space through a graph. In other words, this image was essentially captured by the JWST, a human-made telescope, pointing at the view created by a naturally made telescope, and the combination allows us to see incredibly distant galaxies. The SMACS 0723 galaxy cluster is so big that it acts as a gravitational lens, in which the cluster’s gravity causes light to bend, as if it were passing through a physical lens. The image was achieved by making a composite of images taken at different wavelengths over a period that totalled 12.5 hours. These are all galaxies and the dots that have smudged or dragged are galaxies that are much farther away. While these take up a lot of the image, what is more interesting is the smaller dots spread in between. The large bright white lights scattered across the image are stars found in our galaxy, the Milky Way. This small section of the Universe covers a patch of sky that is roughly the size of a grain of sand held at arm’s length by someone standing on Earth. The image shows a distant galaxy cluster: SMACS 0723, seen here as it was 4.6 billion years ago. It came out the night before and was unveiled by President Joe Biden. In a surprise turn of events, one image was released on its own. NASA has promised the deepest image of our universe that has ever been taken, and these first sets of images are only the first step in a long job of expanding our view of the universe.īut what can you expect from these images, when and where can you see them this week and what will they cover? The first images from the JWST Deep image The James Webb Space Telescope took 30 years and $10 billion to build, has flown over 1.5 million kilometres away from Earth, and now, we can finally see the first glimpse of its power with a collection of images.
