Astronomers study planetary transits and atmospheric signals using interstellar object 3I/ATLAS, drawing on transit spectroscopy principles and recent observational constraints discussed by Avi Loeb.

Visual demonstration of the performance of the diffraction grating. The zeroth order transmission refers to light that goes straight through the grating without undergoing diffraction (which should be ...

The Schmidts' philanthropic research organization will build a 3-meter space telescope and fund three ground-based facilities.

Spectroscopy remains a cornerstone of modern science, underpinning our ability to probe the intrinsic energy levels of atoms and molecules with remarkable precision. By interpreting the interaction of ...
