Incredible Hulk? Nah, this glowing, green light in the night sky is a comet

8 years 1 month ago
A gigantic, green-tinged comet is currently smashing its way through the night sky, leading some people to dub it the "Incredible Hulk comet." Tomorrow (Aug. 7), the celestial object will make its closest approach to Earth, according to Sky and Telescope magazine. This is likely the first time the comet has ever come into the inner solar system.

Next time you eat a blueberry (or chocolate chip) muffin consider what happened to the blueberries in the batter as it was baked. The blueberries started off all squished together, but as the muffin expanded they started to move away from each other. If you could sit on one blueberry you would see all the others moving away from you, but the same would be true for any blueberry you chose. In this sense galaxies are a lot like blueberries.

NASA created a rare, exotic state of matter in space

8 years 1 month ago
NASA has cooled a cloud of rubidium atoms to ten-millionth of a degree above absolute zero, producing the fifth, exotic state of matter in space. The experiment also now holds the record for the coldest object we know of in space, though it isn't yet the coldest thing humanity has ever created. (That record still belongs to a laboratory at MIT.)
