"Cambridge, MA - Two separate teams of scientists have identified major challenges for the development of life in what has recently become one of the most famous exoplanet systems, TRAPPIST-1. "
"The teams, both led by researchers at the Harvard-Smithsonian Center for Astrophysics (CfA) in Cambridge, Mass., say the behavior of the star in the TRAPPIST-1 system makes it much less likely than generally thought, that planets there could support life."
"An Earth-sized planet next door: that was the startling announcement last August. Astronomers had found an exoplanet orbiting the sun’s closest stellar neigh- bor, a cool red dwarf star called Proxima Centauri (1). Even better, the nearby world orbited within its parent star’s habitable zone, meaning liquid water could exist on the planet’s surface, which raised the prospects for its harboring life."

Hannah Jang-Condell, our alum who received her Ph.D. in 2004, has been given tenure at the University of Wyoming. She is an Associate Professor in their Physics and Astronomy Department. She studies planet formation theory, protoplanetary disk models, extrasolar planets, computational astrophysics, astrobiology. Congratulations, Hannah!
In case you haven't already heard the news about Ryan Hickox - a former Harvard grad student - now tenured professor at Dartmouth! Ryan also is one of the first "house professors" in the house system that Dartmouth is expanding:
Astronomy Undergraduates in Ay100 Observational Astronomy course over spring break went on a trip. They traveled to the Desert Museum, University of Arizona mirror lab to see telescope mirrors being made, and to Whipple observatory to observe on the 1.2-m and 1.5-m telescope collecting data for their class project.
I am very sorry to report that our colleague Pat Thaddeus passed away this morning.
Pat was a highly influential teacher and astronomer for over 50 years, including the past 30 at the CfA. His interests were extremely broad, including pioneering work on the cosmic microwave background radiation, planetary atmospheres, and large-scale studies of star formation and galactic structure. He was one of the founders of the now flourishing field of astrochemistry. His elegant laboratory spectroscopy provided ironclad identifications of many new...
Congratulations to Astronomy graduate student, Xiawei Wang, was selected as one of the eight Harvard Horizons scholars. The symposium will take place on Wednesday, April 12, 2017 at 4:30PM in Sanders theater. Read more
"A new citizen-science project will rescue tens of thousands of potentially valuable cosmic images that are mostly dead to science and bring them fully back to life. Called Astronomy Rewind, the effort, which launches today (22 March 2017), will take photographs, radio maps, and other telescopic images that have been scanned from the pages of dusty old journals and place them in context in digital sky atlases and catalogs. Anyone will then be able to find them online and compare them with modern electronic data...
Local public radio station WBUR recently broadcast a segment about the Watertown play Silent Sky about the Harvard College Observatory "computers:" Meredith Hughes (PhD 2010) is interviewed at the end of the segment about her great-grandmother, a former head computer at Lockheed Martin. ...
"As the Faculty of Arts and Sciences works to address a “concerning” lack of diversity in the body, some have turned to astronomy professor John A. Johnson’s efforts as an example of creating opportunities for historically underrepresented minorities.
Harvard Graduate student Marion Dierickx recent paper featured:
"The 11 farthest known stars in our galaxy are located about 300,000 light-years from Earth, well outside the Milky Way's spiral disk. New research by Harvard astronomers shows that half of those stars might have been ripped from another galaxy: the Sagittarius dwarf. Moreover, they are members of a lengthy stream of stars extending one million light-years across space, or 10 times the width of our galaxy."
The 2017 Annie Jump Cannon Award for outstanding research and promise for the future by a postdoctoral woman scientist goes to Rebekah Dawson (Pennsylvania State University, Harvard Astronomy PhD 2013) for her work modeling the dynamical interactions of exoplanets in multiplanet systems. Her studies help explain exoplanets’ mutual orbital inclinations and eccentricities as well as their migration toward and away from each other and their host star. She has also...
The American Astronomical Society has selected Professor Charlie Conroy to receive the Helen. B. Warner Prize for 2017. The prize includes a cash award and an invitation to give a plenary talk, hopefully at the upcoming summer AAS meeting in Austin, Texas. AAS Press Release
