Scientists discover a new phase of high-density, ultra-hot ice

The outer planets of our solar system, Uranus and Neptune, are water-rich gas giants. These planets have extreme pressures 2 million times the Earth's atmosphere. They also have interiors as hot as the surface of the sun. ...

Old stars don't have hot Jupiters, suggests study

As we began to discover hundreds, then thousands of exoplanets, we found that there were two types of worlds unlike anything in our solar system. The first are super-Earths. These worlds straddle the line between large rocky ...
