    In 2012, the Dark Energy Spectroscopic Instrument (DESI) was commissioned to measure the effect of dark energy, the mysterious force driving the expansion of the cosmos. Since then, the DESI Legacy Imaging Surveys have obtained optical images of tens of millions of galaxies and quasars, including through NOIRLab’s Nicholas U. Mayall 4-meter Telescope at Kitt Peak National Observatory (KPNO). In recent news, the DESI Legacy Imaging Surveys team made its 11th data release (DR 11), constituting the largest-ever 2D map of the universe.

    The 5.6-trillion-pixel map contains nearly 4 billion celestial objects, including stars, galaxies, black holes and asteroids...

    Universe’s Missing Matter Found by FRBs
    A landmark study led by the Center for Astrophysics | Harvard & Smithsonian (CfA) has pinpointed the Universe’s “missing” matter using Fast Radio Bursts (FRBs)— brief, bright radio signals from distant galaxies— as a guide. This artist’s conception depicts a bright pulse of radio waves (the FRB) on its journey through the fog between galaxies, known as the intergalactic medium. Long wavelengths, shown in red, are slowed down compared to shorter, bluer wavelengths, allowing astronomers to “weigh” the otherwise invisible ordinary matter.
