Researchers have developed a new technology that can shape the spectrum of light emitted from a laser frequency comb across the visible and near-infrared wavelengths with more precision than ...
Astronomers have now observed the radio emission from the neutral hydrogen gas (HI) in a nearby galaxy. Hydrogen gas emits radio emission in a spectral line at a very specific frequency of 1420 MHz.
The sun's inner corona, the hottest part of our star's atmosphere, appears faint yellow in a time-lapse made from images taken by the ASPIICS coronagraph aboard Proba-3. An international team of ...
