An influential group of geologists, ecologists, and biologists argue that humans have so changed the planet that it is entering another phase of geological time, called the Anthropocene, “the Age of Man.”
On Sunday, September 16, the sun did not rise above the horizon in the Arctic. Nevertheless enough of the sun’s heat had poured over the North Pole during the summer months to cause the largest loss of Arctic sea ice cover since satellite records began in the 1970s.

One of Europe’s main contributions to the James Webb Space Telescope (JWST) is built and ready to ship to the US. The Mid-Infrared Instrument (Miri) will gather key data as the $9 billion observatory seeks to identify the first starlight in the Universe. James Webb – regarded as the successor to Hubble – is due…
Since its launch in 2008, the Fermi space telescope has recorded hundreds of gamma-ray bursts (GRBs), flashes of light that, for just a few seconds or minutes, are the brightest objects in the Universe. And now the telescope is yielding data that is starting to explain the mechanisms that unleash these beam-like jets of light,…
There’s a reason we only ever see one side of the Moon. It’s tidally locked to the Earth, presenting only one side to us as it orbits around the planet. Tidal locking is a fate that befalls lots of planetary bodies, and it can wreak havoc on the surface. Why does tidal locking happen? And…
