Visible planets align this month

A once-in-a-decade celestial show is marching across the sky every morning for a few weeks this winter--Mercury, Venus, Saturn, Mars and Jupiter will be visible in the early morning sky. Viewers can see them lined up diagonally in the east around 6 a.m., according to Lara Eakins, astronomy education and outreach coordinator. more..

Casting Complete for Giant Magellan Telescope Mirror Four

The casting crew at the Richard F. Caris Mirror Lab at the University of Arizona has lifted the oven lid on the fourth GMT mirror to find a perfect casting. The innovative process heats 18 tons of glass to a temperature of 2,120°F in a spinning furnace with a honeycomb mold. The glass is cooled after four hours to 1,652°F, and then slowly over three months to room temperature to avoid strains in the mirror. The resulting parabolic shape, saves countless hours of polishing, and tons of glass. Photos of mirror four have been posted by the GMTO on Facebook (photo credit: Ray Bertram, Richard F. Caris Mirror Lab, University of Arizona):

Project Manager of GALEX, Kepler, Keck Interferometer Appointed at Giant Magellan Telescope

Pasadena, CA — The Giant Magellan Telescope Organization (GMTO) announces the appointment of Dr. James Fanson as Project Manager. The GMTO conducted an international search to identify candidates for this position, and Dr. Fanson stood out in a field of accomplished project managers. Dr. Fanson has held multiple positions at NASA’s Jet Propulsion Laboratory (JPL) since he joined the organization in 1986. He served as Project Manager for GALEX (Galaxy Evolution Explorer), Kepler, and the Keck Interferometer. In addition, he held key technical and managerial roles for the Spitzer Space Telescope, Hubble Space Telescope’s Wide-Field Planetary Camera 2, and other missions. more..

High School Senior Helps Discover Planet, Calculates Frequency of Jupiter-like Planets

AUSTIN — High school senior Dominick Rowan of Armonk, New York, is making discoveries about other worlds. Working with University of Texas at Austin astronomer Stefano Meschiari, Rowan has helped to find a Jupiter-like planet and has calculated that this type of planet is relatively rare, occurring in three percent of stars overall. They used an online version of software previously created by Meschiari, called "Systemic Live", that lets students visualize and manipulate real data from telescopes around the world, to try to find the signatures of extrasolar planets as-yet unknown. Their research has been accepted for publication in the Astrophysical Journal. more..
