Tim Peake and space station crew mates return to Earth

Many galaxies blast huge, wide-angled flows of material outward from their centres, pushing to their outer edges enough dust and gas each year that otherwise would have formed more than a thousand stars the size of our Sun. A team led by University of Maryland scientists has found the driving force behind these massive molecular outflows.

Live coverage of the launch of British ESA astronaut Tim Peake to the International Space Station. The three-man Expedition 46 crew led by five-time space flier Yuri Malenchenko will ride a Soyuz rocket into orbit, speeding away from a Kazakh launch pad on a six-hour chase of the International Space Station. Liftoff is occurred on time at 1103 GMT.

Astronomers using NASA and ESA X-ray space telescopes discover that PDS 456, an extremely bright black hole known as a quasar more than 2 billion light-years away, sustains winds that carry more energy every second than is emitted by more than a trillion suns.
