Swedish Photographer Christian Aslund visited Svalbard, in the Arctic Circle, to document the retreat of glaciers. He found that they look very different from archival images taken up to a century ago.

UK startup Pulsar Fusion is developing Sunbird, a nuclear fusion rocket that could drastically cut down journey times in space, shown here in an artist’s impression. Pulsar Fusion Sunbird’s fusion process would only require grams of fuel — in the form of deuterium and helium-3 — and would not produce any radioactive waste. Pulsar Fusion The rocket, shown in a rendering, would wait in orbit for spacecraft to attach itself to and carry to destination.

British startup Magdrive has developed what it calls a game-changing propulsion system for satellites, shown here in a render, which is 10 times more maneuverable and 10 times smaller than current options. Look through the gallery to see more. Magdrive Magdrive is set to launch its first full prototype into space later this year. Because it runs on solid metal, the system, shown in this render, could one day be powered by space junk collected in orbit.

Wind power has been rising significantly in recent years, and now accounts for about 8% of the world’s energy production. By the end of the decade, it will be the second-largest renewable source after solar, having surpassed hydropower, according to the International Energy Agency. Wind turbines are more efficient than solar panels — they harness, on average, about 50% of the energy that goes through them compared to about 20% for solar — but are more dependent on location.
