In a quest to find mismatched star pairs known as extreme mass-ratio binaries, Harvard astronomers have discovered a new class of binary stars, in which one star is fully formed while the other is still in its infancy. The discovery of these stellar twins could provide invaluable insight into the formation and evolution of massive stars, close binaries, and star nurseries.
For doctoral student Sarah Rugheimer, the study of atmosphere holds deep promise in the search for extrasolar life.

Astronomers announced Tuesday that they have found eight new planets in the Goldilocks Zone of their stars, orbiting at a distance where liquid water can exist on the planet's surface. The discoveries double the number of small planets believed to be in the habitable zone of their parent stars.
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.
For life as we know it to develop on other planets, those planets would need liquid water, or oceans. Geologic evidence suggests that Earth’s oceans have existed for nearly the entire history of our world.
Despite a malfunction that ended its primary mission in May 2013, the Kepler spacecraft is alive and working. The evidence comes from the discovery of a new super-Earth using data collected during Kepler’s “second life.”
Harvard-Smithsonian Center for Astrophysics scientist Jonathan McDowell answers questions on the Orion test run and prospects for getting to Mars.

New research by theorists at the Harvard-Smithsonian Center for Astrophysics (CfA) shows that we could spot the fingerprints of certain pollutants under ideal conditions. This would offer a new approach in the search for extraterrestrial intelligence (SETI).
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 announced Monday that they have discovered a new type of planet — a rocky world weighing 17 times as much as Earth. This planet is all solids and much bigger than previously discovered “super-Earths,” making it a “mega-Earth.”
Astronomers have created the first realistic virtual universe using a computer simulation called Illustris. Illustris can re-create 13 billion years of cosmic evolution in a cube 350 million light-years on a side with unprecedented resolution.

Kepler-78b is a planet that shouldn’t exist. “This planet is a complete mystery,” said astronomer David Latham of the Harvard-Smithsonian Center for Astrophysics (CfA). “We don’t know how it formed or how it got to where it is today. What we do know is that it’s not going to last forever.”
Scientists at the Harvard-Smithsonian Center for Astrophysics are drafting the target list for NASA’s next planet-finding telescope, the orbiting Transiting Exoplanet Survey Satellite, or TESS, which will search the Earth’s galactic neighborhood for planets that might support life.
Harvard’s Matt Holman, a lecturer on astrophysics, and his collaborators at the Southwest Research Institute in Colorado are piggybacking their research onto a NASA spaceship that is racing to the farthest edges of the solar system to study objects in the far-flung Kuiper Belt.
New observations confirm that colliding neutron stars create short gamma-ray bursts, and such collisions produce rare heavy elements, including gold. Researchers at the Harvard-Smithsonian Center for Astrophysics believe the Earth’s gold likely came from colliding neutron stars.
Gerhard Sonnert, a research associate at the Harvard-Smithsonian Center for Astrophysics, has created a new website that allows listeners to literally hear the music of the stars.

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.
Two communications specialists at the Chandra X-Ray Observatory have authored a guide to the universe, aiming to show people around a universe they say belongs to us all.

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.
CfA fellow David Kipping is heading a hunt for astronomical bodies at the edge of our ability to detect them: moons circling planets in other solar systems.
Using a continent-spanning telescope, an international team of astronomers has peered to the edge of a black hole at the center of a distant galaxy. For the first time, they have measured the black hole's "point of no return" — the closest distance that matter can approach before being irretrievably pulled into the black hole.
At first glance, the center of the Milky Way seems like a very inhospitable place to try to form a planet. New research by astronomers at the Harvard-Smithsonian Center for Astrophysics shows that planets still can form in this cosmic maelstrom.
Alex Parker, a postdoctoral fellow at the Harvard-Smithsonian Center for Astrophysics, sees astronomical data as art as well as science.

Before 2004, the most recent Venus transit occurred more than a century ago, in 1882, and was used to compute the distance from the Earth to the sun. On June 5, 2012, another Venus transit will occur. Scientists with NASA's Kepler mission hope to discover Earth-like planets outside our solar system by searching for transits of other stars by planets that might be orbiting them. The next Venus transit: Dec. 11, 2117.

New research by astronomers at the University of Utah and the Harvard-Smithsonian Center for Astrophysics shows that supermassive black holes can grow big by ripping apart double-star systems and swallowing one of the stars.
Seven years ago, astronomers boggled when they found the first runaway star flying out of our galaxy at a speed of 1.5 million miles per hour. The discovery intrigued theorists, who wondered: If a star can get tossed outward at such an extreme velocity, could the same thing happen to planets? New research shows that the answer is yes.
Astronomy Professor Daniel Eisenstein is using a new understanding of spacing between galaxies to build a 3-D map of the cosmos and confirm theories about its structure.
