Astronomers have uncovered a hidden cosmic web of galaxies and gas by mapping hydrogen light from the early universe.

This article examines the spectroscopic properties of young stellar objects, linking accretion dynamics to observed ...

At a distance of just over four light years, Proxima Centauri is our nearest stellar neighbor and is known to be a very active M dwarf star. Its flare activity has been well-known to astronomers using ...

Radio astronomy opens a window onto the invisible universe. While our eyes can detect visible light, countless objects in space emit radiation at much longer wavelengths, in the radio portion of the ...

Imagine going to a library where the books aren’t books at all, but detailed information on stars throughout our galaxy. Stars are the building blocks of clusters and galaxies; the information ...

Spectroscopy is a group of investigative techniques based on matter-light interactions, and Raman spectroscopy is a subcategory focused on the distinct infrared or visible light scattering caused by ...

A Raman spectroscopy system uses a laser to illuminate a target sample and a spectrometer to detect inelastic light scattering. The scattered light is displaced in wavelength from the laser emission ...
