Pasadena, CA — Using information gathered from several telescopes, a team of astronomers, including Carnegie’s Eric Murphy, searched the sky for very rarely seen dusty starburst galaxies, formed soon...
Pasadena, CA—For only the second time in history, a team of scientists--including Carnegie's Michele Fumagalli--have discovered an extremely rare triple quasar system. Their work is published by...
Pasadena, CA— A team of astronomers including Carnegie’s Ian Thompson have managed to improve the measurement of the distance to our nearest neighbor galaxy and, in the process, refine an...
Pasadena, CA—Type II supernovae are formed when massive stars collapse, initiating giant explosions. It is thought that stars emit a burst of mass as a precursor to the supernova explosion. If...
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...

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 Giant Magellan Telescope will be one member of the next class of super giant earth-based telescopes that promises to revolutionize our view and understanding of the universe. It will be constructed in the Las Campanas Observatory in Chile. Commissioning of the telescope is scheduled to begin in...
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...
Gwen Rudie studies the chemical and physical properties of very distant galaxies and their surrounding gas in order to further our understanding of the processes that are central to the formation and development of galaxies. Critical to this research is our ability to trace the raw...
The entire universe—galaxies, stars, and planets—originally condensed from a vast network of tenuous, gaseous filaments, known as the intergalactic medium, or the gaseous cosmic web. Most of the matter in this giant reservoir has never been incorporated into galaxies; it keeps floating...
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...

Pasadena, CA— A team of astronomers from three institutions has developed a new type of telescope camera that makes higher resolution images than ever before, the culmination of 20 years of...
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...
A star traveling at ultrafast speeds after being ejected by the supermassive black hole at the heart of our galaxy was spotted by an international team of astronomers including Carnegie’s Ting...
