Our solar system's journey around the center of the Milky Way takes it through varying galactic environments, and one may ...

According to Einstein’s theory of general relativity, gravitational waves warp spacetime. In the process, they could imprint ...

“Second sound is the hallmark of superfluidity, but in ultracold gases so far you could only see it in this faint reflection ...

Scientists investigate gravitational wave memory theory by Einstein, searching for traces in the cosmic microwave background.

Uncover the surprising connection between Earth storms and space radiation through the effects of lightning on high-energy ...

When it starts taking scientific data in 2028, the Square Kilometre Array Observatory promises to be the world’s largest and ...

The farthest spacecraft from Earth are shutting off instruments in interstellar space, but their mission in interstellar ...

Binary neutron star mergers occur millions of light-years away from Earth. Interpreting the gravitational waves they produce presents a major challenge for traditional data-analysis methods. These ...

A CT scan exposes your body to some radiation. That involves a small amount of risk, and it’s important to understand the issues. A CT scan uses what’s called “ionizing” radiation.

When you have cancer, though, some cells start to divide way too fast. That's where radiation therapy can help. It uses high-energy particles to make tiny breaks in the DNA of cancer cells to ...

Scientists blasted the 4,600-year-old structure with electromagnetic waves, a form of radiation that travel though the universe, finding it focused and amplified the energy into specific ...

as passing through these radiation belts can pose a risk to their systems. In May 2024, Earth experienced its most powerful solar storm in two decades. For several days, intense waves of charged ...
