By all measures, graphene shouldn’t exist. The fact it does comes down to a neat loophole in physics that sees an impossible 2D sheet of atoms act like a solid 3D material. New research has delved into graphene’s rippling, discovering a physical …
So time only moves forward—or does it? Physicists usually refer to this idea as the “arrow of time,” and the idea of unidirectional time seems to hold true for life and objects on a human scale. But on a quantum scale, things seem to work very d…
Stellar collisions are an amazingly rare thing, especially for us humans. According to our best estimates, such events only occur in our galaxy (within globular clusters) once every 10,000 years. It’s only been recently, thanks to ongoing improv…
If you think the Earth is flat, then you’re on the wrong website. Seriously, what are you doing here? Why aren’t you venturing to the icy mountainous rim around the edges, bravely peeking underneath and seeing what’s on the other side of this g…
Astronomers just discovered 72 never-before-seen galaxies using the Multi Unit Spectroscopic Explorer (MUSE) instrument on the ESO’s Very Large Telescope (VLT) in Chile as part of the deepest spectroscopic survey ever conducted. These galaxi…
Living bacteria have been found on the outside of the International Space Station, and they may be extraterrestrial, according to one cosmonaut. Russian engineer Anton Shkaplerov said the microorganisms were not there at the launch of the ISS in…
Black holes are something everyone has heard about, but few actually know anything about. They are like giant invisible blenders lurking in the corners of deep space, sucking in unsuspecting stars and planets and ripping them to shreds. We're…
Artist's Impression Two years ago, NASA made a big splash when it announced the discovery of flowing water on the surface of Mars . But it turns out, the space agency might have been wrong. The surface features that NASA thought were mad…
