NOAA's Premier Weather Forecast Model Goes 4-D | Department of Commerce

NOAA's Premier Weather Forecast Model Goes 4-D | Department of Commerce: NOAA’s powerful new supercomputers paved the way for another upgrade to the U.S. Global Forecast System (GFS), NOAA’s primary model for weather prediction. Today’s upgrade builds on last year’s significant boost to the GFS, which more than doubled the resolution of the model grid from 27 kilometers to 13 kilometers, resulting in higher resolution model output and more precise weather forecasts and warnings.

Computer-Simulated Image of a Supermassive Black Hole

Computer-Simulated Image of a Supermassive Black Hole: Astronomers have uncovered a near-record breaking supermassive black hole in an unlikely place: in the center of a galaxy in a sparsely populated area of the universe. The observations, made by NASA’s Hubble Space Telescope and the Gemini Telescope in Hawaii, may indicate that these monster objects may be more common than once thought.

Hubble, Chandra, Jansky VLA Telescopes Collaborate on Galaxy Cluster

Hubble, Chandra, Jansky VLA Telescopes Collaborate on Galaxy Cluster: In October 2013 Hubble kicked off the Frontier Fields program, targeting six massive galaxy clusters, enormous collections of hundreds or even thousands of galaxies. MACS J0717, shown here, is one of the most complex galaxy clusters known, the result of four galaxy clusters colliding.

March 16, 1966: Gemini's First Docking of Two Spacecraft in Earth Orbit

March 16, 1966: Gemini's First Docking of Two Spacecraft in Earth Orbit: On March 16, 1966, command pilot Neil Armstrong and pilot David Scott successfully docked their Gemini VIII spacecraft with the Agena target vehicle, the first-ever linking of two spacecraft together in Earth orbit. This crucial spaceflight technology milestone would prove vital to the success of future moon landing missions.
