The planet might have a liquid environment, meaning life exists in the darkness. The rather imaginatively named planet WISE 0855-0714 is the closest rogue planet to our solar system at a distance of 7 light-years. They are discovered when they pass before a star because they do not orbit ...
Venus is Earth's closest planetary neighbour and both bodies are of similar size and mass. As a consequence, Venus is often described as Earth's sister planet. But the two worlds have followed very different evolutionary paths, with Earth having benign surface conditions, whereas Venus has a ...
“My name is Heather Knutson, and I’m a professor in the planetary science department here at Caltech. I study the properties of extrasolar planets, which are planets that orbit stars other than the sun, so mostly these are our closest exoplanetary neighbors. We’re not talking about plan...
