"Aliens might have existed during the Universe’s infancy. A set of calculations suggests that liquid water — a prerequisite for life — could have formed on rocky planets just 15 million years after the Big Bang..." (Nature, Article)
Recent technical advances and observations have now demonstrated that the goal of making an image of a black hole is within reach. Using the technique of Very Long Baseline Interferometry (VLBI), in which widely separated radio dishes are linked together to form an Earth-sized array, our group has succeeded in confirming event horizon scale structures in two super massive black holes: Sagittarius A*, the 4 million solar mass black hole at the center of the Milky Way (Nature, 455, 78, '08), and M87, a 6 billion solar mass black hole in the giant elliptical galaxy Virgo A (Science, 338, 355...
The Evolving Physical Processes in Interacting Galaxies Traced by Their Spectral Energy Distributions
Mergers and interactions have profound effects on the evolution of galaxies and on the various physical processes associated with star formation and the fueling of active nuclei (AGN). There remains, however, an incomplete understanding of how interactions affect such processes or how important they are in controlling the appearance of today's universe. Recent Harvard grad Lauranne Lanz for her thesis successfully completed a multi-band analyses (GALEX-Herschel) of set of 31...
A team of planet hunters estimates that about 22 percent of the Sun-like stars in our galaxy may have planets about the size of Earth that are bathed in similar amounts of sunlight — and potentially habitable. That's the conclusion of a new analysis by Erik Petigura, a graduate student at the University of California, Berkeley of observations taken by NASA's Kepler Space Telescope, which was launched in 2009 to hunt for potentially habitable Earth-like planets around other stars....

Each year, the MacArthur Foundation names several dozen of the nation's most creative and influential people as MacArthur Fellows which provides funds for two years which the recipients can use toward any purpose. The Class of 2013 awardees includes Harvard alumna Sara Seager.
Referring to them as "an array of the most brilliant," David Bjerklie and the editors of Time Magazine in a photo-centric supplement entitled The 25 Most Influential People in Space named Avi Loeb, Dave Charbonneau, Adam Reiss and Sara Seager for their contributions to astronomical research.
The Derek Bok Center for Teaching and Learning works to advance the quality of undergraduate education by providing Harvard’s teachers with resources, programs and support that promote excellence in teaching. Each semester it recognizes with a Certificate of Distinction in Teaching those student instructors whose work is exemplary based on peer evaluations.
What is dark matter? Well, we know what it's probably not: black holes. Astronomy Chair, Avi Loeb, and several colleagues decided to test the idea whether or not smallish black holes could be the source of the universe's dark matter, and Time Magazine's Michael Lemonick has written an excellent overview of their conclusions.
Professor Bob Kirshner celebrates the successful casting of the third of seven mirrors for the Giant Magellan Telescope which the Dean of FAS, Michael Smith, has just approved as a major funding-raising focus for the University. The casts are made under the University of Arizona football stadium overseen by the Steward Observatory there.
