Dark energy is still one of the greatest cosmic mysteries. For all the time, money and telescopes that humanity has used to uncover its nature, scientists are still asking a fundamental question: What is dark […]

Scientists have created the highest resolution map of the dark matter that threads through the universe—showing its influence on the formation of stars, galaxies and planets.This post was originally published on this site

Using the Baryons Oscillation Spectroscopic Survey (BOSS) spectrograph, astronomers have discovered five new carbon-enhanced metal-poor stars in the Large Magellanic Cloud (LMC). This is the first time such stars have been identified in this galaxy. […]

Like a recording artist who has had a long career, NASA’s Chandra X-ray Observatory has a “back catalog” of cosmic recordings that is impossible to replicate. To access these X-ray tracks, or observations, the ultimate […]

The British astronomer and mathematician Edmond Halley was not, after all, the first to understand the cycle of the comet that now bears his name. This is shown by research conducted by, among others, Professor […]

A research team has investigated quasar variability by tracking optical to mid-infrared (MIR) wavelengths of variability information. This multiband joint analysis provides an opportunity to probe the dust structure in the quasar’s central region and […]

Researchers at the Max Planck Institute for Extraterrestrial Physics (MPE), in collaboration with astrophysicists from the Centro de Astrobiología (CAB), CSIC-INTA, have identified the largest sulfur-bearing molecule ever found in space: 2,5-cyclohexadiene-1-thione (C₆H₆S). They made […]

Some stars appear to defy time itself. Nestled within ancient star clusters, they shine bluer and brighter than their neighbors, looking far younger than their true age. Known as blue straggler stars, these stellar oddities […]

The Dark Energy Survey Collaboration collected information on hundreds of millions of galaxies across the universe using the U.S. Department of Energy-fabricated Dark Energy Camera, mounted on the U.S. National Science Foundation Víctor M. Blanco […]

An international research team led by scientists at Waseda University and Tohoku University has discovered an extraordinary quasar in the early universe that hosts one of the fastest-growing supermassive black holes known at this mass […]
