New map of universe reveals its history for the past 6 billion years
The scientists of the Sloan Digital Sky Survey (SDSS), including astronomers at Penn State, have produced a new map of the universe that is in full color, covers more than one quarter of the entire sky, and is full of so much detail that you would need 500,000 high-definition TVs to view it all. The […] … learn more→
New astronomy tool peers through the heart of the Milky Way
A powerful new tool for probing the structure of our galaxy has been developed by astronomers associated with the Sloan Digital Sky Survey, including two Penn State astronomers. The new tool is an infrared spectrograph for the Apache Point Observatory Galactic Evolution Experiment (APOGEE). It is the newest instrument deployed by the Sloan Digital Sky […] … learn more→
City lights could reveal extraterrestrial civilization
Astronomers searching for extraterrestrial intelligence typically have mined for radio signals and ultra-short laser pulses, but researchers from Princeton and Harvard universities now suggest a seemingly more straightforward method — see who\’s left the light on. Edwin Turner, a professor in Princeton\’s Department of Astrophysical Sciences, and Avi Loeb, professor and chair of Harvard\’s Department […] … learn more→
\’Darkest\’ world enlightens astronomers about mysterious light-gobbling planet
A giant Jupiter-like gas planet has been revealed to be the most light-thirsty object in the known universe — a finding that may help astronomers better understand a mysterious characteristic of similar planets found outside our solar system. Recent analysis on a planet dubbed TrES-2b has found that it probably absorbs 99.9 percent of the […] … learn more→
