The South Pole Telescope (SPT) is a 10-meter-diameter telescope in the Antarctic that has been operating at millimeter- and submillimeter-waves for a decade; the CfA…
There are currently over 3500 confirmed exoplanets known thanks to the remarkable sensitivity of the Kepler spacecraft and to technological advances in space and ground-based…
An axion is a hypothetical elementary particle whose existence was postulated in order to explain why certain subatomic reactions appear to violate basic symmetry constraints,…
Astronomers had a mystery on their hands. No matter where they looked, from inside the Milky Way to distant galaxies, they observed a puzzling glow…
The direct detection of gravitational waves from at least five sources during the past two years offers spectacular confirmation of Einstein’s model of gravity and…
Astronomers from the Harvard-Smithsonian Center For Astrophysics have measured the sizes of the accreting regions around the supermassive black holes in four distant AGN using…
Astronomers studying the Toothbrush Cluster with new radio observations combined with other wavelengths have been able to confirm the galaxy merger scenario and estimate the…
The center of our Galaxy has been intensely studied for many years, but it still harbors surprises for scientists. A snake-like structure lurking near our…
Sunspots are regions on the Sun’s photosphere that appear darker than surrounding areas because they are cooler, usually by one or two thousand degrees Celsius….
Astronomers have concluded from the study of NGC 1600 and similar galaxies that the relative populations of stars of different masses in a cluster of…
The path of a light beam will be bent by the presence of mass, an effect explained by General Relativity, and a massive body can…
A coalition of U.S. educational institutions has launched an online database of opportunities around the world for high school students to get involved in research…
The next generation of the Sloan Digital Sky Survey (SDSS-V), directed by Juna Kollmeier of the Carnegie Institution for Science, will move forward with mapping…
This new image taken by NASA’s Juno Spacecraft shows Jupiter’s southern hemisphere in beautiful detail. The color-enhanced view captures one of the white ovals in…
Harvard scientists have proposed a new way to use photons of light instead of silicon chips as qubits, opening the door to new quantum technologies….
The Giant Magellan Telescope Organization (GMTO) announced that it has initiated the casting of the fifth of seven mirrors that will form the heart of…
Astronomers have succeeded in measuring precisely the distance to a source on the other side of the galaxy, a region that has so far been…
Astronomers reveal that a small, recently discovered asteroid — or perhaps a comet — has entered our solar system from somewhere else in our galaxy….
