Washington, D.C.— An international team of scientists, including Carnegie’s Paul Butler, has discovered that Tau Ceti, one of the closest and most Sun-like stars, may have five planets. Their work is...
Pasadena, CA— A team of astronomers including Carnegie’s Daniel Kelson have set a new distance record for finding the farthest galaxy yet seen in the universe. By combining the power of NASA's Hubble...
Washington, D.C.—Astronomers have discovered a new super-Earth in the habitable zone, where liquid water and a stable atmosphere could reside, around the nearby star HD 40307. It is one of three new...
Washington, D.C.--Scientists with the Giant Magellan Telescope Organization have completed the most challenging large astronomical mirror ever made. The mirror will be part of the 25-meter Giant...
Pasadena, CA— A team of astronomers, led by Wendy Freedman, director of the Carnegie Observatories, have used NASA's Spitzer Space Telescope...
Pasadena, CA— With the combined power of NASA's Spitzer and Hubble Space Telescopes, as well as a cosmic magnification effect, a team of astronomers, including Carnegie’s Daniel Kelson, have spotted...
Washington, D.C.—Type Ia supernovae are violent stellar explosions. Observations of their brightness are used to determine distances in the universe and have shown scientists that the universe is...
Pasadena, CA—Type Ia supernovae are important stellar phenomena, used to measure the expansion of the universe. But astronomers know embarrassingly little about the stars they come from and how the...

The Carnegie Hubble program is an ongoing comprehensive effort that has a goal of determining the Hubble constant, the expansion rate of the universe, to a systematic accuracy of 2%. As part of this program, astronomers are obtaining data at the 3.6 micron wavelength using the Infrared Array...
The Earthbound Planet Search Program has discovered hundreds of planets orbiting nearby stars using telescopes at Lick Observatory, Keck Observatory, the Anglo-Australian Observatory, Carnegie's Las Campanas Observatory, and the ESO Paranal Observatory. Our multi-national team has been...
The Carnegie-Spitzer-IMACS (CSI) survey, currently underway at the Magellan-Baade 6.5m telescope in Chile, has been specifically designed to characterize normal galaxies and their environments at a distance of about 4 billion years post Big Bang, expresses by astronomers as z=1.5.
The survey...
While the planets in our Solar System are astonishingly diverse, all of them move around the Sun in approximately the same orbital plane, in the same direction, and primarily in circular orbits. Over the past 25 years Butler's work has focused on improving the measurement precision of stellar...
Alan Boss is a theorist and an observational astronomer. His theoretical work focuses on the formation of binary and multiple stars, triggered collapse of the presolar cloud that eventually made the Solar System, mixing and transport processes in protoplanetary disks, and the formation of gas...
We are all made of stardust. Almost all of the chemical elements were produced by nuclear reactions in the interiors of stars. When a star dies a fraction of the elements is released into the inter-stellar gas clouds, out of which successive generations of stars form.
Astronomers have a basic...
