It didn't have to be the case — it could have been that these planets were very, very hot on the dayside and very cold on the nightside, but apparently there are these very strong winds that can move energy around to the cold side, so the nightside on those planets is really quite hot.

The team's measurements suggest the planet's nightside would actually exhibit a ruddy glow because its temperature appears to be in excess of 1,000 degrees Celsius — as hot as a blast furnace.
