In about 1.3 million years, the star system Gliese 710 is set to pass directly through our Oort Cloud, an event visualized in a dramatic scene in Encounters in the Milky Way. During its flyby, our systems will swap icy comets, flinging some out on new paths.

The eye is first drawn, in this new NASA/ESA/CSA James Webb Space Telescope Picture of the Month, to the central mega-monster that is galaxy cluster Abell S1063. This behemoth collection of galaxies, lying 4.5 billion light-years from Earth in the constellation Grus (the Crane), dominates the scene. Looking more closely, this dense collection of heavy galaxies is surrounded by glowing streaks of light, and these warped arcs are the true object of scientists??? interest: faint galaxies from the Universe???s distant past. Abell S1063 was previously observed by the NASA/ESA Hubble Space Telescope???s Frontier Fields programme. It is a strong gravitational lens: the galaxy cluster is so massive that the light of distant galaxies aligned behind it is bent around it, creating the warped arcs that we see here. Like a glass lens, it focuses the light from these faraway galaxies. The resulting images, albeit distorted, are both bright and magnified ??? enough to be observed and studied. This was the aim of Hubble???s observations, using the galaxy cluster as a magnifying glass to investigate the early Universe. The new imagery from Webb???s Near-Infrared Camera (NIRCam) takes this quest even further back in time. This image showcases an incredible forest of lensing arcs around Abell S1063, which reveal distorted background galaxies at a range of cosmic distances, along with a multitude of faint galaxies and previously unseen features. This image is what???s known as a deep field ??? a long exposure of a single area of the sky, collecting as much light as possible to draw out the most faint and distant galaxies that don???t appear in ordinary images. With 9 separate snapshots of different near-infrared wavelengths of light, totalling around 120 hours of observing time and aided by the magnifying effect of gravitational lensing, this is Webb???s deepest gaze on a single target to date. Focusing such observing power on a massive gravitational lens, like Abell S1063, therefore h
