The Royal Observatory Greenwich (ROG) is to start studying the sky again after a break of 60 years. British astronomy's historic home has installed new telescopes in its Grade II listed Altazimuth Pavilion, which has also undergone a restoration. The new facility is to be named after Annie Maunder, one of the first female scientists to work at the ROG and who made key discoveries about the Sun. Professionals, amateurs and school children will use the instruments.
That's Maunder as in Maunder Minimum. More details :

Charles II founded the Greenwich site in 1675. Its purpose was to map the stars and compile tables that could then be used for navigation at sea. It was a working observatory until 1957, after which serious science retreated to the countryside to get away from urban smog and light pollution. But with cleaner air and new technologies, it is now possible for telescopes to take very decent pictures again from the capital, says ROG astronomer Brendan Owens.
"We can use what are called narrow-band filters to get around the light pollution, and then there are the new processing techniques. We can take very fast frame-rate snapshots and use only the steadiest shots to build the final result. It's known as 'lucky dip imaging'," he told BBC News.
