Noise and misinformation, especially on climate, has long been a problem on social media. To counter this, Australian not-for-profit the Climate Council has created a Facebook Messenger chatbot to inform people about climate science. Launched on its Facebook page last week, it's an effort to connect with younger people who are interested in issues like climate change, but aren't the most engaged with the organisation -- largely due to broader information overload. "Young people are saturated on social media because they're the most active on it, we know that they care and that they've got the thirst for information," Nelli Huié, digital manager at the Climate Council, explained. "But because they've got the highest use of social media, they've got the most voices clamouring to reach them through the News Feed. It can be a real challenge for us to cut through that noise."

Airbus' Perlan 2 aircraft has made history this week, setting a new world altitude record for gliding. The aircraft soared to an incredible 52,000 feet over the Patagonia region of Argentina, without the support of an engine. The flight takes Airbus one step closer to its ultimate goal of sending an engine-less aircraft to the edge of space. Airbus' Perlan 2 aircraft has made history this week, setting a new world altitude record for gliding.

NASA's satellite captured a polar vortex sweeping across Canada and the US Images show temperatures will be 20 to 30 degrees below the average this week It is set to head for the north central and northeastern US December 14 and 15 These areas will experience wind chills ending up in the -10 to -25 degrees F NASA's satellite captured a polar vortex sweeping across Canada and the US A polar vortex is expected to deliver temperatures 20 to 30 degrees below the average this week. These predictions stem from imagery collected by the Atmospheric Infrared Sounder instrument attached to NASA's Aqua satellite that measures temperature data in infrared light Juno captures stunning image of one of Jupiter's'pearls':...
