44 Planets Beyond the Solar System
Speckle imaging observations made at the WIYN telescope on Kitt Peak have been used, in combination with data from other facilities, to confirm the existence of 44 exoplanets. Four of the planets have orbital periods shorter than a day. Sixteen have sizes within twice that of the Earth. The graphic illustrates the planetary sizes and surface temperatures and compares their orbital radii to that of Mercury. The discoveries were made by a team that includes NOAO astronomer Mark Everett.

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. -
New results suggest that most, if not all, of the known asteroids originate from only a few “common ancestors”. The study was done by a team that includes NOAO astronomer Dan Li. -
The Mayall telescope’s new top end ring was recently installed using a 450 ton crane with a 250 foot boom. The top ring will support new optics for the Dark Energy Spectroscopic Instrument (DESI).
