... Armagh Observatory, College Hill, Armagh BT61 9DG, +44 (0)28 3752 2928 . ... Armagh Observatory, 30 July 2015: The sky above a nearby "failed star" or brown dwarf lying in the summer constellation Lyra shimmers with a beautiful green and yellow aurora ten thousand times brighter than the northern lights. ... Even a few years ago, brown dwarfs were thought by most astronomers to be incapable of emitting any significant radio emission, so its first detection came as a great surprise. ...

... Astronomers have used a new technique to see the faint light from a planet that is orbiting a distant star. ... Instead, astronomers found them by looking for telltale clues, such as how the light from a star dims when an exo-planet passes in front of it, or how it wobbles because of the pull of an exo-planet s gravity. Astronomers can learn a lot about exo-planets that move in front of their stars. This is because the starlight passes through the exo-planet s atmosphere on its way to Earth. ...
