Exploring the Dynamic Sky

It ranks among the most important images ever produced by astronomers. The Hubble eXtreme Deep Field (XDF) showed that an incredibly small patch of sky in the constellation Fornax, thought to have nothing in it, was in fact filled with thousands of distant galaxies, the earliest of which had formed within half a billion years […]

Mike Brown is famous as the man who ‘demoted’ Pluto from being the Solar System’s ninth planet. Could he now have found evidence for its replacement? We spoke to him to find out. Since 1988, astronomers have detected more than 2,000 planets orbiting distant stars, and it’s a sign of how common this process has […]

Despite this significant extension, the agency did not have a successor […]

Dealing with the Deluge

  Computers have long played an important role in astronomy. It’s just that, back in the late 19th and early 20th centuries, the word was originally applied to people rather than machines—specifically to the men and women who, during daylight hours, carried out repetitive calculations and measurements derived from some of the earliest photographic surveys […]

Dark Skies Recognised

As two more sites in northern England and Scotland earn Dark Sky status, Paul F Cockburn hears how they achieved the award. Light pollution has been a growing problem for the past century, which has seen our view of the night sky obscured by the glow of artificial lighting. One ongoing response to light pollution […]
