The original Sloan Extension for Galactic Understanding and Exploration (SEGUE-1) obtained spectra of nearly 240,000 stars of a range of spectral types. Building on this success, SEGUE-2 spectroscopically observed around 120,000 stars, focusing on the in situ stellar halo of the Milky Way, from distances of 10 to 60 kpc.
The camera includes a filter located between the second and third lenses, and an automatic filter-changing mechanism. Although the camera has six filters covering 330–1080 nm wavelengths, [48] the camera's position between the secondary and tertiary mirrors limits the size of its filter changer. It can hold five filters at a time, so each day ...
The Eyes family of products is available for desktop computers running Windows 7+, and Mac OSX 10.8+. Deep Space Network Now and Experience Curiosity are web-based and available across all platforms. [1] [2] 3D models of spacecraft and other objects are displayed with the option of comparing their size to a human, school bus, or football stadium.
GLIMPSE, the Galactic Legacy Infrared Mid-Plane Survey Extraordinaire, was a series of surveys that spanned 360° of the inner region of the Milky Way galaxy, which provided the first large-scale mapping of the galaxy. [45] [46] It consists of more than 2 million snapshots taken in four separate wavelengths using the Infrared Array Camera. [47]
Designed to survey a portion of Earth's region of the Milky Way to discover Earth-size exoplanets in or near habitable zones and to estimate how many of the billions of stars in the Milky Way have such planets, [6] [11] [12] Kepler's sole scientific instrument is a photometer that continually monitored the brightness of approximately 150,000 ...
MilkyWay@home is a volunteer computing project in the astrophysics category, running on the Berkeley Open Infrastructure for Network Computing (BOINC) platform. Using spare computing power from over 38,000 computers run by over 27,000 active volunteers as of November 2011, [3] the MilkyWay@home project aims to generate accurate three-dimensional dynamic models of stellar streams in the ...
The photomosaic from NASA's "Wave at Saturn" campaign. The collage includes some 1,600 photos taken by members of the public on The Day the Earth Smiled. The Day the Earth Smiled is a composite photograph taken by the NASA spacecraft Cassini on July 19, 2013.
SIM Lite measurements of Milky Way stars were to yield data to understand four topics: fundamental galactic parameters, the Oort Limit, disk mass potential, and mass of the Galaxy to large radii. [15] The first, fundamental galactic parameters, was aimed at answering key questions about the size, shape and the rotation rate of the Milky Way. [16]
