If that planet has an active core, you also get a magnetosphere, which helps a lot with radiation shielding, plus things like plate tectonics. We don't have decent, light radiation shields either, so until people start building force fields that keep out radiation, a magnetosphere is ...
"We had figured out how the Earth works, and Mercury is another terrestrial, rocky planet with an iron core, so we thought it would work the same way," Christopher Russell, a professor at the University of California, Los Angeles, said in aUniversity of California, Los Angeles statement. ...
Recently, the discovery of a gaseous debris disk with a composition similar to that of ice giant planets14 demonstrated that massive planets might also find their way into tight orbits around white dwarfs, but it is unclear whether these planets can survive the journey. So far, no intact ...

What makes Uranus the coldest planet in the solar system? Uranus is the only planet that is really in thermal equilibrium with the sun and there are two options as to why its surface appears cold. Firstly it could just actually be that Uranus is hot in its interior, but this heat ...
(288 degrees Fahrenheit); and the temperature on Venus, which is almost as hot as the hottest temperature on Mercury, is constant. The outer gas giants — Jupiter, Saturn, Uranus and Neptune — all have surfaces that compare with Mercury at its coldest, but they become warmer deeper inside...
It is the coldest atmosphere in the solar system with a minimum temperature of 49 K (−224 °C; −371 °F). Voyager 2 remains the only investigation of Uranus, studying the structure and composition of the atmosphere, moons, and rings while also making additional discoveries. Voyager ...
Currently, there are two theories as to why Uranus is sometimes the coldest planet. First, Uranus appears to have been slammed onto its side by an earlier collision, which would cause heat from the planet’s core to escape into space. According to the second theory, Uranus’s lively atmosph...
The model couples the MITgcm dynamical core92, a finite-volume code that solves the 3D primitive equations on a staggered Arakawa C grid93, with a plane-parallel, two-stream version of a multi-stream radiation code developed for planetary atmospheres94. Opacities are calculated using the ...
Even while Google Earth becomes more technologically advanced, much of the planet's sea floor can't be measured because water interferes with radio waves. Although technology has allowed humanity to create maps of all the earth's oceans with a resolution of up to about three miles, we are ab...
