A new map of cosmic expansion suggests that dark energy evolves over time, hinting that the universe doesn’t work the way we ...

(Alternatively the complete emission spectrum may be observed by feeding the amplifier output on to a chart recorder and driving the spectrometer as in conventional optical spectroscopy.) ...

As temperatures rise and we spend more time outdoors, it's crucial to pay attention to the ultraviolet (UV) index. This important metric, often found on weather apps alongside temperature readings, ...

They believed that radiation from the sun and solar system ... Spectrographs scatter light from an object into a spectrum: a chart or a graph that shows the intensity of light being emitted ...

defects can be altered over geologic time in the earth or by exposure to heat or radiation during color treatment. So-called optical defects (or optical centers) cause absorption in the visible or ...

The Canadian-built Atacama Cosmology Telescope in the high Chilean desert mountains, which has just given up its final batch ...

It also created two new bands of radiation around the planet, researchers report in the February JGR Space Physics. Earth is encircled by two donut-shaped bands of particles called the Van Allen ...

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.

Researchers from The Ohio State University have developed a prototype battery that converts nuclear radiation into electricity through light emission. The findings, published in Optical Materials: X, ...

The Official Philippines Chart has officially launched in the country! Its official launch party, held on Wednesday evening in Bonifacio Global City, Taguig, was attended by today’s top artists like ...

Radiation therapy is a cancer treatment that uses high-frequency waves to destroy cancer cells. Doctors determine the type and dose of radiation based on the type and location of the cancer, your ...

market-changing solutions that are designed to deliver radiation treatments for even the most complex cases—while making commonly treatable cases even easier—to meet the full spectrum of ...
