This tail of hydrogen is huge — about 50 times larger in size than the red dwarf star the planet orbits.

Because these planets are light years away, and because the reflected light is incredibly dim, the James Webb Space Telescope will only be able to do this for large planets that orbit red and white dwarfs — but still, it's incredibly exciting to think that we might be able to identify signs of life from all the way over here on our little blue marble.
