Why our location in the Milky Way is perfect for finding alien life

Our arm of the Milky Way is filled with older, metal-rich stars. New research suggests these might provide the best conditions for life to form on their planets

NIRCam and MIRI imaging An enormous mosaic of Stephan?s Quintet is the largest image to date from the NASA/ESA/CSA James Webb Space Telescope, covering about one-fifth of the Moon?s diameter. It contains over 150 million pixels and is constructed from almost 1,000 separate image files. The visual grouping of five galaxies was captured by Webb?s Near-Infrared Camera (NIRCam) and Mid-Infrared Instrument (MIRI). With its powerful, infrared vision and extremely high spatial resolution, Webb shows never-before-seen details in this galaxy group. Sparkling clusters of millions of young stars and starburst regions of fresh star birth grace the image. Sweeping tails of gas, dust and stars are being pulled from several of the galaxies due to gravitational interactions. Most dramatically, Webb?s MIRI instrument captures huge shock waves as one of the galaxies, NGC 7318B, smashes through the cluster. These regions surrounding the central pair of galaxies are shown in the colours red and gold. This composite NIRCam-MIRI image uses two of the three MIRI filters to best show and differentiate the hot dust and structure within the galaxy. MIRI sees a distinct difference in colour between the dust in the galaxies versus the shock waves between the interacting galaxies. The image processing specialists at the Space Telescope Science Institute in Baltimore opted to highlight that difference by giving MIRI data the distinct yellow and orange colours, in contrast to the blue and white colours assigned to stars at NIRCam?s wavelengths.

We live in a cosmic void so empty that it breaks the laws of cosmology

Mounting evidence suggests our galaxy sits at the centre of an expanse of nothingness 2 billion light years wide. If so, we may have to rethink our understanding of the universe
