NASA has released a full set of images from its James Webb Space Telescope, showing what is said to be the "deepest" and most detailed picture of the cosmos to date: nasa.gov/webbfirstimages/
Picture 1 - The Carina Nebula
one of the largest and brightest nebulae in the sky, located roughly 7,600 light-years from Earth. Nebulae are stellar nurseries. They are a massive clouds of gas and dust in which new stars are forming. Astronomers refer this to a "cosmic reef", or "cosmic cliff" - a kind of broad demarcation between dust in the bottom half, and then gas in the top half. One of Webb's key scientific goals is to study how stars form, and Carina is an excellent place to do that.
Picture 2 - Stephan's Quintet
A galaxy cluster showing huge shockwaves and tidal tails. This is a front-row seat to galactic evolution. This image is of a group of five galaxies, two of which are in the process of merging. Although called a "quintet" only four of the galaxies are truly interacting in a cosmic dance - the one on the left is actually in the foreground.
Picture 3 - The Southern Ring
A giant expanding sphere of gas and dust that's been lit up by a dying star in the centre. As stars age, they change the way they make energy and eject their outer layers. And then, when the star gets very hot again, it energises all that material it had previously spurned. The Southern Ring is nearly half a light-year in diameter and is located about 2,000 light-years from Earth.
