But the real “star” is the planet HD 97658b, not much more than twice the Earth's diameter and a little less than eight times its mass. HD 97658b is a…
In industrial and high-tech settings, diamonds are particularly valued for their hardness, optical clarity, smoothness, and resistance to chemicals, radiation…
In this month's special issue of Physics World devoted to the “physics of cancer”, Paul Davies, principal investigator at Arizona State University's Center for…
A team of scientists at USC has verified that quantum effects are indeed at play in the first commercial quantum optimization processor.The team demonstrated…
The technique, called Through-Focus Scanning Optical Microscopy (TSOM), has now been shown able to detect tiny differences in the three-dimensional shapes of…
Finding extrasolar planets has become so commonplace that it seems astronomers merely have to look up and another world is discovered. However, results from…
A new report by an independent task force commissioned by the American Association of Physicists in Medicine (AAPM), has found that people absorb less…
Others form in huge, dense swarms that survive for billions of years as stellar clusters. Within such rich and dense clusters, stars jostle for room with…
Our present understanding of thermodynamics is fundamentally incorrect if applied to small systems and needs to be modified, according to new research from…
The universe is awash in terahertz (THz) waves, as harmless as they are abundant. But unlike other regions of the electromagnetic spectrum, THz has proven to…
These particles cannot travel through the atmosphere to harm humans on Earth, but they can affect electronic systems in satellites and on the ground.Experimental NASA research models, based on observations from NASA's Solar Terrestrial Relations Observatory and ESA/NASA's Solar and Heliospheric Observatory show that the CME left the sun at speeds of around 1350 miles per second, which is a fast speed for CMEs….
Nestled inside this constantly changing magnetic bubble lies a donut of charged particles generally aligned with Earth’s equator. Known as the ring current,…
But transistors based on semiconductors can only get so small. “At the rate the current technology is progressing, in 10 or 20 years, they won’t be able to get…
The resulting hybrid technology could eventually lead to computer and data-storage chips that pack more components in a given area and are faster and less…
When two galaxies stray too close to each other they begin to interact, causing spectacular changes in both objects. In some cases the two can merge — but in…
The eruption and subsequent splashdown were observed in spectacular detail by NASA's Solar Dynamics Observatory. This spacecraft watches the Sun 24 hours a…
