To see the various colors that make up starlight, astronomers can use a prism to separate the colors. Common elements like helium and calcium in the atmospheres of stars block certain colors of light, ...

The discovery of 13 diffuse interstellar bands with the longest wavelengths to date could someday solve a 90-year-old mystery. Astronomers have identified the new bands using data collected by the ...

Insight-HXMT’s discovery of the fundamental electron cyclotron absorption line near 146 keV for the first Galactic ultraluminous X-ray pulsar Swift J 0243.6+6124. Neutron stars have the strongest ...

An international team of astronomers led by professor Neeraj Gupta, astronomer at the Inter University Centre for Astronomy and Astrophysics (IUCAA), India, on Wednesday released the most ...

SPECTROSCOPIC investigations on the scattering of light in crystals show very plainly that their vibration spectra have a discrete structure manifesting itself as a set of lines with sharply defined ...

XES is an element-specific method primarily used to analyze the partially occupied electronic structure of materials. The technique is one of the photon-in-photon-out spectroscopies in which an ...

Neutron stars have the strongest magnetic fields in the universe, and the only way to measure their surface magnetic field directly is to observe the cyclotron absorption lines in their X-ray energy ...
