Why are the water molecules glowing?

If WASP-121b were any closer to its host star, it would be ripped apart by the star's gravity. The top of the planet's atmosphere is heated to 2,500 degrees Celsius -- so hot that iron can exist only as a gas, instead of a solid.

Exactly how the stratosphere can remain intact at such a high temperature is something the researchers want to investigate.
