How can the temperature of the Sun's atmosphere be as high as 1 million degrees Celsius when its surface temperature is only around 6000°C? By simulating the evolution of part of the Sun's interior ...

The doomed Martian moon Phobos, which is on a slow death spiral above the Red Planet, may hold some secrets about how Mars was formed. The moon's orbit of Mars — gradually degrading over the eons — ...

The Moon has no real atmosphere, but Earth has, in a sense, been generously trying to share its own for billions of years. A ...

The optimal land–-atmosphere coupling heights for Earth system models tend to be near the top of the surface layer. This finding provides a potential guideline for setting proper reference heights for ...

Scientists have shown how the swirling winds and searing heat on Venus work together in a revealing new study. The surface of Venus is hot enough to melt lead with temperatures averaging 872 degrees ...

Chemical reactions in the Arctic atmosphere are accelerating warming and reshaping climate far beyond the polar region.

NASA’s New Horizons spacecraft is the gift that keeps on giving. After completing a historic flyby of Pluto on July 14, the spacecraft continues to provide scientists with never-before-seen views of ...

NASA announced on Wednesday that two new missions have been selected as part of NASA's Discovery Program, which will be venturing to Venus in order to study the atmosphere and surface of Earth's ...

The isotopic composition of water in ice cores is used as a proxy for past climate. Traditional interpretation of this recorded climate signal is that during formation precipitation captures a ...

Determining the composition of the atmosphere of Titan and the nature of the aerosols making up the surface-hiding haze layers are two of the primary objectives of the Cassini-Huygens mission. Whereas ...
