Rapid changes point to origin of ultra-fast black hole winds

01 March 2017

Astronomers have made the most detailed observation yet of an ultra-fast wind emanating from a Black Hole at a quarter of the speed of light. Using the European Space Agency (ESA)’s XMM-Newton and NASA’s NuSTAR telescopes, the scientists observed the phenomenon in an active galaxy known as IRAS 13224-3809.

Newly discovered planets could have water on their surfaces

22 February 2017

An international team of astronomers has found a system of seven potentially habitable planets orbiting a star 39 light years away three of which could have water on their surfaces raising the possibility they could host life. Using ground and space telescopes, the team identified the planets as they passed in front of the ultracool dwarf star known as TRAPPIST-1. ̽»¨Ö±²¥star is around eight per cent of the mass of the Sun and is no bigger than Jupiter.
