NASA’s Wide-field Infrared Survey Explorer may be running out of coolant, but its infrared sensors are still capturing some amazing infrared views of the cosmos. Today in pretty space pics: the Flame nebula, a burning candle lighting up the larger Orion complex close to its well-known belt.
Using NASA’s Wide-field Infrared Survey Explorer telescope, astronomers have finally spotted a collection of ultra-cool brown dwarfs they have been hunting for more than a decade. These tepid almost-star orbs are nearly impossible to see with a normal telescope, but WISE’s infrared vision was able to pick them out.
After almost a year of successfully surveying the entire sky one-and-a-half times over, NASA’s Wide-Field Infrared Survey Explorer has run out of coolant – quite expectedly – and reached the end of its primary mission. Since its launch last December, the mission snapped more than 1.8 million images in four different infrared wavelengths, providing astronomers with enough data to keep them busy combing through it for decades. That is to say, WISE has had a very productive year.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
