The sheer scale of Carrazco-Gaxiola’s survey, titled “An All-Sky Spectroscopic Reconnaissance of More Than 2,100 K Dwarfs Within 40 Parsecs Using High-Resolution Spectra,” is what sets it apart.
Observations of nearby red dwarf stars reveal rare carbon and oxygen isotopes, offering direct evidence of stellar nucleosynthesis and the chemical evolution of the Milky Way.
A paper links dark stars to Webb telescope puzzles involving bright sources, dust-free galaxies, and early black holes.
The James Webb Space Telescope is now delivering what astronomers have chased for decades: a glimpse of the universe’s first generation of stars. By dissecting the light from a tiny, distant galaxy, ...
A team of astronomers have created the first standardized set of measurement guidelines for analyzing and cataloguing stars. Previously, as with the longitude problem 300 years earlier for fixing ...
