Voluminous clouds of cosmic dust permeate our galaxy, but only recently has software allowed detailed observations of the ...

Astronomers have constructed the first detailed 3D map of the properties of cosmic dust in our home galaxy. For their map, the astronomers used 130 million spectra from ESA's Gaia mission, results ...

When we observe distant celestial objects, there is a possible catch: Is that star I am observing really as reddish as it ...

Previous efforts to map the galaxy's dust were challenged by limited data, but the Gaia mission has provided a treasure trove ...

The James Webb Space Telescope has transformed how scientists study the universe. With its unmatched ability to detect near-infrared light, it reveals details of distant galaxies once thought ...

[2] DESI's early data contain nearly 3.5 million unique galaxy spectra. The sample used in this work was selected based on redshift (distance) and accurate detection of emission lines.

Previously, Hubble Telescope users had to make multiple successive observations of the spectra at different locations around a galaxy center in order to determine the rate at which the stars and ...

shifting them towards the red end of the spectrum. The more red-shifted the light from a galaxy is, the faster the galaxy is moving away from Earth.
