• The Rosetta mission comes to a dramatic ending with a crash landing on Comet 67P/Churyumov-Gerasimenko but not before its eagle-eyed camera spots the missing Philae lander wedged in a crevice.
• Scientists at the European Southern Observatory have announced the discovery of a possibly Earth-like world orbiting one of the nearest stars to our own Solar System. We reveal what we know about this new world in our neighbourhood.
• We ask is visual observing dead in this age of digital imaging. Five prominent visual observers have their say and we offer ten of the best visual sights to see in the night sky.
