Somewhere in the millimeter-wave static that washes over southern Arizona, there is a faint signal from galaxies that lit up ...
Yes. Each spectral line corresponds to a specific energy transition related to a particular atom — and thus, element. Astronomers analyze such lines to tell us what celestial objects are made of. In ...
One of the biggest unanswered questions in solar physics is why the Sun’s corona — its outermost atmosphere — is vastly ...
Researchers developed a new type of spectral shaper that can shape the spectrum of 10,000 lines of light from a laser frequency comb. The image shows the spatial light modulator they used with a 2D ...
The team uses the "Little Garden" spectrometer to measure spectral lines from reference gas tubes and compares them with ...
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 ...
