Harvard researchers have found that stars slow down as they age, and their ages are well-kept secrets. But astronomers are taking advantage of the first fact to tackle the second and tease out stellar ages.
At a Meeting of the Faculty of Arts and Sciences on April 1, 2014, the Minute honoring the life and service of the late John Peter Huchra, Robert O. and Holly Thomis Doyle Professor of Cosmology, was placed upon the records. Professor Huchra pioneered the exploration of the universe through redshift surveys at the Harvard-Smithsonian Center for Astrophysics and played an instrumental role in the establishment of the current rate of cosmic expansion, the key ingredient in establishing the age of the Universe.
Astronomers have identified a new structure in the Milky Way: a long tendril of dust and gas that they are calling a “bone.”
The quest for a twin Earth is heating up. Francois Fressin, of the Harvard-Smithsonian Center for Astrophysics (CfA), presented the new analysis of Kepler data that shows that about 17 percent of stars have an Earth-sized planet in an orbit closer than Mercury.
Harvard astronomers Robert P. Kirshner and Gaspar Bakos were honored this month (Jan.) by the American Astronomical Society.
