If you’ve seen the first images from the James Webb Space Telescope this week, you might have heard the term “gravitational lensing” being thrown around. But what does it mean exactly? And how can it help this new telescope make discoveries?

A huge range of dark matter suspects are being investigated. In a new study, astronomers have searched for clouds of hypothetical ultralight particles that could congregate around black holes, and reveal themselves by sending out gravitational waves.

Astronomers have reported a bumper crop of new gravitational wave detections. The 35 new signals, comprising the third Gravitational-Wave Transient Catalog (GWTC-3), help scientists probe the depths of the cosmos in more detail.

The interplay between high blood pressure and brain health is one scientists continue to shed new light on, with a new study finding even those with readings at the higher end of the normal recommended range can be at risk of premature brain aging.

Researchers have rediscovered a century-old cancer treatment, injecting dead bacteria into tumors to help the immune system target and kill the cancerous cells. Early human trials indicate the treatment is safe and potentially effective.

Astronomers have detected the final piece of the gravitational wave trifecta – a black hole swallowing a neutron star. Two separate events rolled in just days apart, with the black holes gobbling up the stars like Pac-Man rather than Cookie Monster.

Scientists at the Australian National University (ANU) have developed a new type of night-vision technology that is the first of its kind, taking the shape of an ultra-thin film that can be applied directly to glasses.

Dotted with thousands of giant stone vessels, the Plain of Jars in Laos is one of the most intriguing archeological sites in Southeast Asia. A new study has uncovered how old the jars are – and it turns out they're much older than previously thought.

An international team of researchers has succeeded in producing two types of diamonds in a matter of minutes, demonstrating a new technique where they not only form quickly, but do so at room temperature.

Lightning is a major trigger for wildfires, like the record-breaking blazes that devastated Australia and California this year. But what if we could redirect lightning to strike safely? Graphene particles trapped in a tractor beam could do just that.

The star Betelgeuse has dimmed twice in the past year. Now astronomers say they’ve found what may have caused the latest episode – and also discovered that the star is smaller, closer to Earth and further from exploding than previously thought.

Radioactive isotopes found in ocean sediments show that Earth has been traveling through a cloud of fallout from an ancient supernova for the past 33,000 years. A new study indicates that could only have been of extraterrestrial origin.
