The Dark Energy Spectroscopic Instrument is conducting a five-year survey to create the largest 3D map of the Universe ever. Astronomers are now performing init

Washington DC (SPX) Oct 19, 2023 - Astronomers have created a detailed atlas of almost 400,000 galaxies in our cosmic neighborhood. The Siena Galaxy Atlas was compiled using data from NSFs NOIRLab telescopes, and is designed to be t

Astronomers have released a huge survey of the galactic plane of the Milky Way

A citizen scientist investigated NSF's NOIRLab's library of 4 billion celestial objects, NOIRLab Source Catalog DR2, to discover brown dwarfs with

"This amazing result clearly demonstrates that NOIRLab's data archive has a reach far beyond that of professional astronomers."

The Dark Energy Survey, a global collaboration including researchers at the University of Wisconsin–Madison, has released DR2, the second data release in the survey’s seven-year history. DR2 was the topic of sessions at the 237th Meeting of the American Astronomical Society, which was held virtually January 10-15. The second data release from the Dark Energy Survey, or DES, is the culmination of over a half-decade of astronomical data collection and analysis with the ultimate goal of under...

DOE/Fermi National Accelerator Laboratory Shown here is the elliptical galaxy NGC 474 with star shells. Elliptical galaxies are characterized by their relatively smooth appearance as compared with spiral galaxies, one of which is to the left of NGC 474, which is oriented with South to the top and West to the left. The colorful neighboring spiral (NGC 470) has characteristic flocculent structure interwoven with dust lanes and spiral arms. NGC 474 is at a distance of about 31 megaparsecs (100 mil...

  One early result of the ongoing Dark Energy Survey is the previously untold story revealed by old, giant RR Lyrae pulsating stars, which tell scientists about the region of space beyond the edge of our Milky Way. In this area nearly devoid of stars–the motion of the RR Lyrae stars hints at the presence of an enormous halo of invisible dark matter, which may provide clues to how our galaxy evolved over the last 12 billion years. One of the Biggest Mysteries in Science Dark matter, one of th...
