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.

Meteorites Reveal Magnetic Record of Protoplanet Churn

The meteorite studied in this work, named Miles, weighed 265 kg when it was discovered on a farm in Queensland, Australia, in 1992. This photo shows a 20-centimeter slice of the Miles meteorite loaned by the Harvard Museum of Natural History collection. (Credit: Clara Maurel/MIT)

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)

AI Finds More Than 1,200 Gravitational Lensing Candidates

Image - A gravitational lens found in the DESI Legacy Surveys data. There are four sets of lensed images that correspond to four background galaxies, which appear as partial rings around an orange galaxy at the center and foreground.

Study: X-Rays Surrounding ‘Magnificent 7’ May Be Traces of Sought-After Particle

Image - An artistic rendering of the XMM-Newton (X-ray multi-mirror mission) space telescope. A study of archival data from the XMM-Newton and the Chandra X-ray space telescopes found evidence of high levels of X-ray emission from the nearby Magnificent Seven neutron stars, which may arise from the hypothetical particles known as axions.
