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.
Science Magazine wrote a biographical article on Avi Loeb. From Cosmic Dawn To Milkomeda, And Beyond: The thoughts of Harvard theorist Avi Loeb traverse the universe, past and future—and he urges young researchers to be just as daring (pdf)
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.

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.
“The nearest Earth-like planet is probably 13 light-years away; astronomically speaking, that’s just a stroll across the park,” said Courtney Dressing (right), a doctoral student in Harvard’s Astronomy Department. At the press conference Dressing was joined by Professor David Charbonneau (center) and John Johnson, an assistant professor of astronomy at the California Institute of Technology.
A new study finds that researchers can detect oxygen in the atmosphere of a habitable planet orbiting a white dwarf (as shown in this artist’s illustration). Here the ghostly blue ring is a planetary nebula — hydrogen gas the star ejected as it evolved from a red giant to a white dwarf.
THE DEEP END: Images of a small patch of sky called the Hubble Ultra Deep Field have revealed several of the most distant galaxies ever seen. The newfound galaxies and their associated redshifts are labeled on the Hubble image. Image: NASA/ESA
Read articles from around the world about the discovery of the earliest galaxies, the deepest archeological dig of the Universe so far. It identified a record redshift of 11.9 for a previously known galaxy and provides the first comprehensive census of baby galaxies when the universe was only 400-400 million years old. Brant Robertson, a PhD alumni of Harvard Astronomy department is a member of the discovery team. He was quoted in the following report.
