A team at Tel Aviv University in Israel and the Harvard-Smithsonian Center for Astrophysics has just discovered an exoplanet using a new method that relies on Einstein’s special theory of relativity.
Understanding student weaknesses
As part of an unusual study that surveyed 181 middle school physical science teachers and nearly 10,000 students, researchers found that the most successful teachers were those who knew what students would get wrong on standardized tests.
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.
Putting the stars within reach
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.
Stars align at astronomy reunion
Harvard astronomers past and present gathered in Cambridge Friday (April 5) for the first-ever reunion of the Harvard Astronomy Department.
A lecturer from the Harvard-Smithsonian Center for Astrophysics says that “dark clouds of gas and dust have the potential to alter Earth’s climate.
A learner’s guide to the universe
Harvard’s Avi Loeb is helping prepare the next generation of astronomers with a new textbook, “The First Galaxies in the Universe.”
Researchers at the Harvard-Smithsonian Center for Astrophysics have found that even dying stars could host planets with life — and if such life exists, they believe we might be able to detect it within the next decade.
Harvard President Drew Faust called for the scientific community to unite in its efforts to press Congress for continued federal research support during a speech to the annual meeting of the American Association for the Advancement of Science.
Earth-like planets potentially capable of supporting life may be right in our galactic neighborhood, according to researchers from the Harvard-Smithsonian Center for Astrophysics and the California Institute of Technology.
An idea that changed the world
Harvard celebrates the 100th anniversary of a computational principle that was little noticed in its time, but that underlies all of modern science.
First ‘bone’ of the Milky Way identified
Astronomers have identified a new structure in the Milky Way: a long tendril of dust and gas that they are calling a “bone.”
Search for Earth’s twin shows promise
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.
Planets form in cosmic maelstrom
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.
Re-creating a slice of the universe
Scientists at the Harvard-Smithsonian Center for Astrophysics and their colleagues at the Heidelberg Institute for Theoretical Studies have made it possible to build a universe from scratch.
Harvard-Smithsonian Center for Astrophysics’ astronomers have detected for the first time jets of gamma rays extending thousands of light years from the Milky Way’s core, confirming expectations based on observations of other galaxies.
The last dance between Venus and the sun
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.
Harvard scientists are participating in the Cambridge Science Festival, 10 days of events where experts in technology, engineering, and math share research with the public.
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.
In distant space, a water world
Observations by NASA's Hubble Space Telescope have added a new type of planet to the mix. By analyzing the previously discovered world GJ1214b, astronomer Zachory Berta of the Harvard-Smithsonian Center for Astrophysics and colleagues proved that it is a water world enshrouded by a thick, steamy atmosphere.
