Artist's illustration of a giant cloud of hydrogen gas streaming off exoplanet GJ 3470b, just 97 light-years from Earth. The exoplanet is tiny compared to its star, a red dwarf named GJ 3470. The star's intense radiation is heating the hydrogen in the planet's upper atmosphere to a point where it escapes into space.
