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 […]

Astronomers have detected extreme, never-before-seen behavior from a rare kind of pulsar and stumbled on a surprising link to one of astronomy’s biggest current mysteries. Using 174 hours of radio observations, researchers detected PSR J1227-4853, a rapidly spinning neutron star known as a “transitional millisecond pulsar,” which unleashes hundreds of ultrashort, ultrapowerful “giant pulses.” Their […]
