Bekki Dawson was awarded the 2013 Fireman Fellowship of the Astronomy department for her PhD thesis, "On the Migratory Behavior of Planetary Systems." Department chair Avi Loeb presented the award to Dawson in an official ceremony on Monday, May 20, 201.
Astronomers have found a planetary system orbiting the star Kepler-62. This five-planet system has two worlds in the habitable zone — the distance from their star at which they receive enough light and warmth for liquid water to theoretically exist on their surfaces.

Harvard Astronomy's Supernova Forensics group has teamed up with Astronomy 100 undergraduate students to unveil the nature of the peculiar SN2012au - a massive star that exploded some 75 million years ago. This energetic, slow-evolving and helium-rich explosion provides a golden link between the emerging class of "super-luminous" supernovae and other more seemingly normal supernovae that are far less bright.
Some observations of the supernova were obtained by two generations of Astro 100 students in 2012 and 2013 as part of the department's annual Spring Break trip to Fred Lawrence Whipple Observatory in Arizona. Students were the first to classify the new supernova in 2012 with the FLWO 1.5m telescope within just hours of its discovery by the Catalina Sky Survey. A year later, the next group of students used the FLWO 1.2m telescope to show that SN2012au is still shining bright and thus evolving slowly. A paper led by postdoc, Dan Milisavljevic, has been submitted to the Astrophysical Journal Letters with details on this unusual stellar explosion (link).
Astronomy Department Chair Avi Loeb discussed the findings from the European Space Agency’s Planck satellite program that showed the universe as being a little older, containing a bit more mysterious dark matter, and expanding more slowly than previously thought.

Each year undergraduate students enrolled in Astronomy 100 hone their practical astronomy knowledge by using the 48-inch and 60-inch telescopes at the Fred L. Whipple Observatory in Arizona. This unique week-long trip during Spring Break includes a visit to the University of Arizona Mirror Lab, 3 nights of hands-on observing, nightly pot-luck dinners cooked by the students and teaching staff, and most importantly, an intimate view of how observational astronomers explore the cosmos. The picture shows the 14 happy students who are currently participating in the observing trip along with Professor Edo Berger and Teaching Fellow Maria Drout (kneeling), with the dome of the 48-inch telescope in the background. The picture was taken by Allyson Bieryla, manager of the Astronomy Lab and Clay Telescope at Harvard.
Cambridge, MA - The star Eta Carinae is ready to blow. 170 years ago, this 100-solar-mass object belched out several suns' worth of gas in an eruption that made it the second-brightest star after Sirius. That was just a precursor to the main event, since it will eventually go supernova.
