Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground.
In our vain human struggle to kill flies, our hands and swatters often come up lacking. This is due to no fault of our own, but rather to flies’ compound…
Truly two-dimensional objects are rare. Even a thin piece of paper is trillions of atoms thick. When physicists do succeed in producing 2D systems, quantum…
Now scientists at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) have taken a key step toward a solution, as described in a…
The Milky Way galaxy is orbited by more than 150 globular star clusters, which are balls of hundreds of thousands of old stars dating back to the formation of…
However, development of quantum computers has been limited as researchers have struggled to find a reliable way to increase the power of these systems, a power…
Reporting today in The Optical Society’s (OSA) high-impact journal Optica, optical and material scientists at the University of Rochester and Swiss Federal…
Using the special properties of graphene, a two-dimensional form of carbon that is only one atom thick, a prototype detector is able to see an extraordinarily…
NASA’s Alice ultraviolet (UV) spectrograph aboard the European Space Agency’s Rosetta comet orbiter has delivered its first scientific discoveries. Rosetta, in…
This discovery clarifies the boundaries of our galactic neighborhood and establishes previously unrecognized linkages among various galaxy clusters in the…
However, the timing of the solar cycle is far from precise. Since humans began regularly recording sunspots in the 17th century, the time between successive…
“If you identify an asteroid coming toward us, how you deal with it could depend on its density and structure,” says Dr. Richard S. Miller, a UAH physics…
Keeping upright in a low-gravity environment is not easy, and NASA documents abound with examples of astronauts falling on the lunar surface. Now, a new study…
Chemical reactions drive the mechanisms of life as well as a million other natural processes on earth. These reactions occur at a wide spectrum of…
The physical behaviour of materials is strongly governed by the many electrons which can interact and move inside any solid. While an individual electron is a…
Many a child has forgotten to hold tight to the string of a helium balloon only to have it escape and rise until it disappeared in the glare of the sun. Helium…
