Using the Gaia satellite & archival data from DECam, astronomers have discovered a large, extremely diffuse galaxy companion to the Milky Way that is as big as the Large Magellanic Cloud but 10,000× fainter. -
Pluto’s terrain shows a “washboard” pattern of fine ridges. The New Horizons team, including NOAO Astronomer Tod Lauer, suggests this is evidence of an ancient nitrogen glacier. -
Cosmic Dance of Tiny Galaxies. Astronomers have discovered that the tiny Sextans dwarf galaxy, 100,000 times less massive than the Milky Way, is merging with an even smaller companion galaxy. -
New extreme dwarf planet discovered, in part with DECam at CTIO, during search for Planet X. Patrolling the outer Solar System on a highly elongated orbit, it travels between 65 and 1000 AU from the Sun. -
Ultra-short Period Planet Found by TESS and Confirmed with CHIRON. This “hot Earth” is in orbit around a star 45 light years away, with a period of just 11 hours. Read more in the paper posted on arXiv. -
The Dark Energy Survey (DES) has released data products used in its Year-One (YI) science programs, including object catalogs, survey characterization maps, and cosmological likelihoods. -
A new $4.5 million grant from the National Science Foundation will fund the development of the Windows on the Universe Center for Astronomy Outreach in the iconic McMath-Pierce Solar Telescope Facility on Kitt Peak.
NOAO is the national center for ground-based nighttime astronomy in the United States and is operated by the Association of Universities for Research in Astronomy (AURA). under cooperative agreement with the National Science Foundation.
