The galaxy NGC 1291 is about 12 billion years old—and that’s old. So what’s it doing with a ring of newborn stars around it? In this newly released image from NASA's Spitzer Space Telescope, trapped gas at the galaxy’s outskirts have triggered star birth.

Over the weekend of October 18, paleontologists with the Idaho Museum of Natural History (IMNH) recovered remains from a 72,000-year-old mammoth. One tusk and partial skull were found near the American Falls Reservoir.
Just a few months back, we heard of a Paris-based design company’s intriguing and thought-provoking new aviation concept: windowless airplanes. While the idea may sound a little too gimmicky to ever come to fruition, a UK company thinks it’s credible and wants to make it a reality within the next decade.

How is it that Earth developed an atmosphere that made the development of life possible? A study published in the journal Nature Geoscience links the origins of Earth’s nitrogen-rich atmosphere to the same tectonic forces that drive mountain-building and volcanism on our planet. It goes some way to explaining why, compared to our nearest neighbours, Venus and Mars, Earth’s air is richer in nitrogen.
