Two years ago, astronomers revealed the first-ever direct images of a black hole. Now, the collaboration behind the historic image has released a new version that shows the polarization of the light around the object.

A landmark proof-of-concept study reveals a novel brain-machine interface using ultrasound tracking brain activity to predict subsequent motor movements. The preliminary research suggests a non-invasive way of controlling computers with one's mind.

A growing body of evidence points to the Red Planet being much bluer in its ancient past. Where all that water went is a key question, with many scientists believing it escaped into space. New analysis suggests another answer: it retreated underground.

As part of a project that could greatly speed up the detection of tsunamis, Caltech and Google researchers have developed a method that turns operating submarine communication cables into earthquake detectors without using special equipment.

A quantum internet would be much faster and more secure than the regular web – and now it may be one step closer to reality. Scientists have used quantum teleportation to send information over long distances, with a higher fidelity than ever before.

Four-wheeled robotic rovers may be a good choice for the exploration of other planets, but they could conceivably get stuck at the bottom of deep craters. NASA's DuAxel rover is designed with that in mind, as it splits in two for steep descents.

If a Mars rover ever were to find signs of life on the Red Planet, chances are that it would be in the form of compounds detected in the soil. A newly designed device could better help it do so, as compared to existing technologies.

Astronomers have identified an asteroid that made the closest pass to Earth ever recorded, and it was only spotted after it had passed. The object skimmed Earth’s atmosphere over the weekend, close enough to have its orbit changed by the gravity.

Astronomers have observed a bright flash of light from space, which appears to have come from a collision between two black holes. And that’s surprising, considering that black holes are famously dark objects.

The LIGO-Virgo collaboration has reported a very strange gravitational wave signal. This signal appears to have come from a black hole swallowing some unknown object, with a mass that sits in a range thought to be empty.

Using polarized light, astronomers have detected signs of cloud bands in the atmosphere of a brown dwarf far beyond the solar system. It turns out that these gassy giants have a similar appearance to Jupiter, and the same kind of wild weather.

All previous records absolutely pale in comparison to the new record holder for the world’s fastest camera, boasting a mind-boggling rate of 70 trillion frames per second. That’s fast enough to capture light waves in movement.
