Image: Hubble captures globular cluster NGC 2298

This new NASA Hubble Space Telescope view shows the globular cluster NGC 2298, a sparkling collection of thousands of stars held together by their mutual gravitational attraction. Globular clusters are typically home to older ...

New nanoparticle source generates high-frequency light

High-frequency light is useful. The higher the frequency of light, the shorter its wavelength—and the shorter the wavelength, the smaller the objects and details the light can be used to see.

Scientists map sulfur residue on Jupiter's icy moon Europa

A Southwest Research Institute-led team used the Hubble Space Telescope to observe Jupiter's moon, Europa, at ultraviolet wavelengths, filling in a "gap" in the various wavelengths used to observe this icy water world. The ...

Enhancing photoelectric efficiency

Albert Einstein might have called this research at Michigan State University a much-needed study. Einstein won a Nobel Prize in Physics in 1921 for explaining the photoelectric effect.

Hot electrons send carbon dioxide back to the future

Atmospheric carbon dioxide (CO2) is a major driver of global warming, but this gas could also serve as a valuable resource. Researchers at KAUST have developed an efficient catalyst that uses light energy to convert CO2 and ...
