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.

You Could Be Flying In A Windowless Plane Within A Decade

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 The Air We Breathe Was Created By Earth’s Tectonic Plates

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.

Planet Spotted Forming In Binary System

Planets may form in multi-star systems more often than we realised and indeed we might even have caught one in the act.

The idea of planets with twin (or more) suns makes for great science fiction visuals and plot devices, but for a long time no one was sure how realistic it was for these to exist.
