http://www.cfa.harvard.edu/news/CfA Press Releasesen-us http://www.cfa.harvard.edu/news/2012/pr201215.htmlMay 22, 2012: The universe is a marvelously complex place, filled with galaxies and larger-scale structures that have evolved over its 13.7-billion-year history. Those began as small perturbations of matter that grew over time, like ripples in a pond, as the universe expanded. http://www.cfa.harvard.edu/news/2012/pr201214.htmlMay 07, 2012: The exploding stars known as Type Ia supernovae serve an important role in measuring the universe, and were used to discover the existence of dark energy. http://www.cfa.harvard.edu/news/2012/pr201213.htmlMay 02, 2012: When it comes to scary things in the universe, it's hard to get much scarier than supermassive black holes. These gigantic, invisible menaces lurk in the centers of galaxies, hungrily vacuuming up everything within reach - or so we think. http://www.cfa.harvard.edu/news/2012/pr201212.htmlApril 17, 2012: New research suggests that billions of stars in our galaxy have captured rogue planets that once roamed interstellar space. http://www.cfa.harvard.edu/news/2012/pr201211.htmlApril 16, 2012: For the last 1000 days the Infrared Array Camera (IRAC), aboard NASA's Spitzer Space Telescope, has been operating continuously to probe the universe from its most distant regions to our local solar neighborhood. http://www.cfa.harvard.edu/news/2012/pr201210.htmlApril 02, 2012: Most galaxies, including the Milky Way, have a supermassive black hole at their center weighing millions to billions of suns. But how do those black holes grow so hefty? http://www.cfa.harvard.edu/news/2012/pr201209.htmlApril 01, 2012: Analysis of data from the 10-meter South Pole Telescope (SPT) is providing new support for the most widely accepted explanation of dark energy - the mysterious force that is responsible for the accelerating expansion of the universe. http://www.cfa.harvard.edu/news/2012/pr201208.htmlMarch 30, 2012: Astronomers announced today that they have made the most accurate measurement yet of galaxy distances in the faraway universe, giving an unprecedented look at the time when dark energy turned on. http://www.cfa.harvard.edu/news/2012/pr201207.htmlMarch 23, 2012: Astronomers have begun to blast 3 million cubic feet of rock from a mountaintop in the Chilean Andes to make room for what will be the world's largest telescope when completed near the end of the decade. http://www.cfa.harvard.edu/news/2012/pr201206.htmlMarch 22, 2012: Seven years ago, astronomers boggled when they found the first runaway star flying out of our Galaxy at a speed of 1.5 million miles per hour. The discovery intrigued theorists, who wondered: If a star can get tossed outward at such an extreme velocity, could the same thing happen to planets? http://www.cfa.harvard.edu/news/2012/pr201205.htmlMarch 20, 2012: An exploding star known as a Type Ia supernova plays a key role in our understanding of the universe. Studies of Type Ia supernovae led to the discovery of dark energy, which garnered the 2011 Nobel Prize in Physics. http://www.cfa.harvard.edu/news/2012/pr201204.htmlFebruary 21, 2012: Our solar system contains three types of planets: rocky, terrestrial worlds (Mercury, Venus, Earth, and Mars), gas giants (Jupiter and Saturn), and ice giants (Uranus and Neptune). http://www.cfa.harvard.edu/news/2012/pr201203.htmlFebruary 15, 2012: Astronomers using NASA's Hubble Space Telescope have found a cluster of young, blue stars encircling the first intermediate-mass black hole ever discovered. http://www.cfa.harvard.edu/news/2012/pr201202.htmlJanuary 11, 2012: Astronomers using NASA's Kepler mission have discovered two new circumbinary planet systems - planets that orbit two stars, like Tatooine in the movie Star Wars. http://www.cfa.harvard.edu/news/2012/pr201201.htmlJanuary 10, 2012: The stars we see today weren't always as serene as they appear, floating alone in the dark of night. Most stars, likely including our sun, grew up in cosmic turmoil - as illustrated in a new image from NASA's Spitzer Space Telescope.
