The probe will gather light shining through a planet's atmosphere as it passes in front of its star as well as light reflected off its dayside surface, just before it passes behind.

This will reveal both the signatures of atmospheric ingredients such as water, methane, and carbon dioxide, and also how heat flows from the planet's dayside to its nightside.

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 dayside would be covered in seas of circulating lava, with the lightest, least viscous lavas flowing toward the night side, where they could cool, grow sluggish and crystallize as solid rock.

The real surprise is that 55 Cancri's dayside is twice as scalding, with its hottest point shifted eastward from its expected position directly beneath the star overhead.

«We need something funny that could be gaseous on the dayside yet still condense out on the nightside.

The dayside of a planet close to an M dwarf, however, might become so hot that water escapes to space; on the frigid nightside, the atmosphere could freeze to the surface.

Rising parcels of hot air could trigger cloud formation, which would reflect lots of sunlight and prevent the dayside from becoming too hot.

The Spitzer data stacked up according to predictions, Tinetti says — especially when combined with eight - micron measurements reported in May by Knutson's team, which used Spitzer to map HD 189733 b's dayside temperature.

The images show with unprecedented clarity both the dayside aurora, seen here over northern Canada, and the nightside aurora over Siberia.

Most, but not all — which is why the dayside aurora looks even brighter than the nightside one here.

At ultraviolet wavelengths, there is less reflected sunlight to swamp the dayside aurora, and the uvi filters out most of what there is.

They likely piled up on the dayside of the planet, acting as a bright shield that reflects incoming sunlight, and never formed on the nightside, letting heat radiate off into space.

With blistering temps hovering at about 4,300 o Celsius, the atmosphere on KELT 9b's dayside is over 700 degrees hotter than the previous record - holder — and hot enough that atoms can not bind together to form molecules.

«Oh the other hand, we'd also be in constant darkness because of tidal locking, and blasted by hurricane - force winds because of the dayside - nightside temperature contrast.
