But most of the atmosphere isn't directly heated by solar radiation, but rather by the terrestrial radiation that the planet itself emits.

At least this planet was not emitting torpedoes or mysterious signals, for once.

All planets emit such radio signals.

It is true that nowhere did the injured planet emit such a howl as at the actual point of penetration, but she showed that she was indeed one entity by her conduct elsewhere.

Ignoring the atmosphere and greenhouse effect, the planet, since it is at a much lower temperature than the Sun, emits mostly in the infrared (IR) portion of the spectrum.

As X-ray detectors have become more sensitive, they have observed that some planets and other normally X-ray non-luminescent celestial objects under certain conditions emit, fluoresce, or reflect X-rays.

"This observation, thus, raises the possibility that even massive planets might emit X-rays by themselves during their youth!"

If the planet emitted another gravitational surge while Poet attempted the maneuver, not only his ship would be affected; the other two could be pulled out of orbit as well.

However, because the Stefan-Boltzmann response mandates that this hotter planet emit more energy, eventually a new radiation balance can be reached and the temperature will be maintained at its new, higher value.

Jupiter's mission detected the relativistic (3-30 MeV) electron population for the first time which the planet was emitting.
