DESI Imaging Legacy Surveys Publish Seventh Data Release
The slideshow above highlights images from the Legacy Surveys’ Data Release 7 (DR7), which covers more than a quarter of the sky. More DR7 images of galaxies in Halton Arp’s Atlas of Peculiar Galaxies are available online.
Read more about DR7 in the latest issue of NOAO Currents, which also describes exoplanet observing time available with CHIRON, news from the SOAR and Blanco telescopes, research opportunities for time domain astronomy (ZTF, ANTARES), and more.

Using DECam on the NSF’s CTIO Blanco telescope, a research team has discovered that supernovae generated by red supergiants are often preceded by a bright flash. -
US scientists invited to help develop exemplar Key Science Programs (KSPs) for GMT and TMT. The KSPs are a key element of the US ELT Program to
be presented to the 2020 Decadal Survey. -
Observations acquired under the NN-EXPLORE program with the WIYN telescope have helped confirm the existence of 44 exoplanets. The discovery team included NOAO astronomer Mark Everett. -
Light echoes from the “Great Eruption” in the mid-1800’s of eta Carinae reveal critical details about a centuries-old event. Read more in the Gemini Observatory press release. -
Observations made with DECam on the CTIO Blanco Telescope have led to the discovery of 12 additional moons of Jupiter, including its smallest known moon, Valetudo, less than one kilometer in diameter. -
Light from a flashlight is dispersed into a spectrum by one of the spectrographs that will be integrated into the Dark Energy Spectroscopic Instrument (DESI) at the 4-m Mayall telescope. -
An international team including NOAO astronomer Tom Matheson views most distant star ever seen, 9 billion light years away. The blue supergiant's light was magnified 2000× by the gravity of a passing star.
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.
