DESI Early Data Release Holds Nearly Two Million Objects

A 3D map of space, with streams of light pointing in different directions from a central focal point. Researchers took detailed images in 20 different directions on the sky, creating a 3D map of 700,000 objects and covering roughly 1% of the total volume DESI will study.

Dark Energy Spectroscopic Instrument (DESI) Creates Largest 3D Map of the Cosmos

Scientific data plot. The earth is in the lower left, looking out in the directions of the constellations Virgo, Serpens and Hercules to distances beyond 5 billion light years. As this video progresses, the vantage point sweeps through 20 degrees towards the constellations Bootes and Corona Borealis. Each colored point represents a galaxy, which in turn is composed of 100 billion to 1 trillion stars. Gravity has clustered the galaxies into structures called the “cosmic web”, with dense clusters, filaments and voids.

Missing Baryons Found in Far-Out Reaches of Galactic Halos

Photo - A new study has found that a share of particles that has gone missing is most likely located at the distant bounds of galaxy haloes. The study found some of these particles of baryonic matter located about 6 million light-years from their galactic centers. This color-rendered image shows the halo of the Andromeda galaxy, which is the Milky Way’s largest galactic neighbor. (Credit: NASA)
