  1. This is first image from NASA’s James Webb Space Telescope is the deepest and sharpest infrared image of the distant universe to date. Known as Webb’s First Deep Field, this image of galaxy cluster SMACS 0723 is overflowing with detail. Thousands of galaxies – including the faintest objects ever observed in the infrared – have appeared in Webb’s view for the first time. This slice of the vast universe covers a patch of sky approximately the size of a grain of sand held at arm’s length by someone on the ground. President Joe Biden unveiled this image of galaxy cluster SMACS 0723 during a White House event Monday, July 11. NASA The $10bn James Webb Space Telescope (JWST), launched on 25 December last year, is billed as the successor to the famous Hubble Space Telescope. It will make all sorts of observations of the sky, but has two overarching goals. One is to take pictures of the very first stars to shine in the Universe more than 13.5 billion years ago; the other is to probe far-off planets to see if they might be habitable. One of the topics to be discussed will touch on that other overarching goal: the study of planets outside our Solar System. Webb has analysed the atmosphere of WASP-96 b, a giant planet located more than 1,000 light-years from Earth. It will tell us about the chemistry of that atmosphere. WASP-96 b orbits far too close to its parent star to sustain life. But, one day, it's hoped Webb might spy a planet that has gases in its air that are similar to those that shroud the Earth - a tantalising prospect that might hint at the presence of biology.
