First Light image (of M51) with the new DESI Corrector Assembly (CA) on the Mayall 4m telescope on Kitt Peak. The CA consists of four ~1m diameter lenses and a two-element atmospheric dispersion corrector, as well as the hexapod, used for fine-motion and focus control of the CA. The image was made with the Commissioning Instrument, composed of five CCD cameras temporarily installed in the DESI focal plane.

  • During the July 2 solar eclipse students from the University of La Serena, with Juan Seguel (CTIO) & Rob Sparks (NOAO), will replicate Eddington’s experiment that confirmed Einstein’s Theory of Relativity.

  • After an 8-week journey that began in Tucson, AZ, the 8.4m-diameter primary mirror of the Large Synoptic Survey Telescope (LSST) has reached its home at Cerro Pachón in Chile.

  • New results from Hubble confirm that the Universe today is expanding faster than expected. The development relies on an earlier study carried out with the SMARTS 1.5m telescope at CTIO.

  • Using an artificial intelligence algorithm to sift through massive amounts of data from NASA’s Kepler Space Telescope, a team of astronomers, including NOAO astronomer Mark Everett, has discovered two new exoplanets.

  • Observations made with the Event Horizon Telescope have captured the first picture of a supermassive black hole. NOAO Astronomer Tod Lauer is a member of the EHT research team.

  • On April 1, the Mayall telescope at Kitt Peak emerged from hibernation and, for the first time, starlight poured through the six large lenses of the Dark Energy Spectroscopic Instrument (DESI).
