Astronomers detect five new 'hot Jupiters'

(Phys.org)—Giant exoplanets, like the so-called 'hot Jupiters' that are similar in characteristics to the solar system's biggest planet and orbit very close to their host stars, are excellent targets for astronomers in ...

The moon

Look up in the night sky. On a clear night, if you're lucky, you'll catch a glimpse of the moon shining in all it's glory. As Earth's only satellite, the moon has orbited our planet for over three and a half billion years. ...

New theory of deep-ocean sound waves may aid tsunami detection

Acoustic-gravity waves are very long sound waves that cut through the deep ocean at the speed of sound. These lightning-quick currents can sweep up water, nutrients, salts, and any other particles in their wake, at any water ...

Twin NASA craft launched to study insides of moon

A pair of spacecraft rocketed toward the moon Saturday on the first mission dedicated to measuring lunar gravity and determining what's inside Earth's orbiting companion - all the way down to the core.

Invisibility cloaking to shield floating objects from waves

A new approach to invisibility cloaking may one day be used at sea to shield floating objects – such as oil rigs and ships – from rough waves. Unlike most other cloaking techniques that rely on transformation optics, ...
