The search for life beyond the solar system is heating up. Though biosignatures around super-Earth K2-18b remain unconfirmed, the JWST has found the planet could be a water-rich ocean world.
If you've ever dreamed of exploring space, you know there'll be some serious dangers. One of them is posed by cosmic rays. These high-speed particles slam through anything, including our bodies, damaging DNA and ripping molecules apart. As dangerous as they sound to unprotected spacefarers, they could actually help microscopic life survive hiding under the icy surfaces of places like Europa or Enceladus.
