Washington, DC— A “cold Neptune” and two potentially habitable worlds are part of a cache of five newly discovered exoplanets and eight exoplanet candidates found orbiting nearby red dwarf stars, which are reported in The Astrophysical Journal Supplement Series by a team led by Carnegie’s Fabo Feng and Paul Butler.

The two potentially habitable planets are orbiting GJ180 and GJ229A, which are among the nearest stars to our own Sun, making them prime targets for observations by next-generation space- and land-based telescopes.  They are both super-Earths with at least 7.5 and 7.9 times our planet’s mass and orbital periods of 106 and 122 days

Washington, DC— Saturn’s icy moon Enceladus is of great interest to scientists due to its subsurface ocean, making it a prime target for those searching for life elsewhere. New research led by Carnegie’s Doug Hemingway reveals the physics governing the fissures through which ocean water erupts from the moon’s icy surface, giving its south pole an unusual “tiger stripe” appearance.

“First seen by the Cassini mission to Saturn, these stripes are like nothing else known in our Solar System,” lead author Hemingway explained. “They are parallel and evenly spaced, about 130 kilometers long and 35 kilometers apart. What makes them

Pasadena, CA— A surprising analysis of the composition  of gas giant exoplanets and their host stars shows that there isn’t a strong correlation between their compositions when it comes to elements heavier than hydrogen and helium, according to new work led by Carnegie’s Johanna Teske and published in The Astronomical Journal. This finding has important implications for our understanding of the planetary formation process. 

In their youths, stars are surrounded by a rotating disk of gas and dust from which planets are born. Astronomers have long wondered how much a star’s makeup determines the raw material from which planets are constructed—

The Anglo-Australian Planet Search (AAPS) is a long-term program being carried out on the 3.9-meter Anglo-Australian Telescope (AAT) to search for giant planets around more than 240 nearby Sun-like stars. The team, including Carnegie scientists,  uses the "Doppler wobble" technique to search for these otherwise invisible extra-solar planets, and achieve the highest long-term precision demonstrated by any Southern Hemisphere planet search.

Superdeep diamonds are  tiny time capsules carrying unchanged impurities made eons ago and providing researchers with important clues about Earth’s formation.  Diamonds derived from below the continental lithosphere, are most likely from the transition zone (415 miles, or 670km deep) or the top of the lower mantle. Understanding diamond origins and compositions of the high-pressure mineral phases has potential to revolutionize our understanding of deep mantle circulation.

Andrew Steele joins the Rosetta team as a co-investigator working on the COSAC instrument aboard the Philae lander (Fred Goesmann Max Planck Institute - PI). On 12 November 2014 the Philae system will be deployed to land on the comet and begin operations. Before this, several analyses of the comet environment are scheduled from an approximate orbit of 10 km from the comet. The COSAC instrument is a Gas Chromatograph Mass Spectrometer that will measure the abundance of volatile gases and organic carbon compounds in the coma and solid samples of the comet.

The WGESP was charged with acting as a focal point for research on extrasolar planets and organizing IAU activities in the field, including reviewing techniques and maintaining a list of identified planets. The WGESP developed a Working List of extrasolar planet candidates, subject to revision. In most cases, the orbital inclination of these objects is not yet determined, which is why most should still be considered candidate planets. The WGESP ended its six years of existence in August 2006, with the decision of the IAU to create a new commission dedicated to extrasolar planets as a part of Division III of the IAU. The founding president of Commission 53 is Michael Mayor, in honor of

Cosmochemist Larry Nittler studies extraterrestrial materials, including meteorites and interplanetary dust particles (IDPs), to understand the formation of the Solar System, the galaxy, and the universe and to identify the materials involved. He is particularly interested in developing new techniques to analyze different variants of the same atom—isotopes—in small samples. In related studies, he uses space-based X-ray and gamma-ray instrumentation to determine the composition of planetary surfaces. He was part of the 2000-2001 scientific team to hunt for meteorites in Antarctica.

Nittler is especially interested in presolar grains contained in meteorites and in what

With the proliferation of discoveries of planets orbiting other stars, the race is on to find habitable worlds akin to the Earth. At present, however, extrasolar planets less massive than Saturn cannot be reliably detected. Astrophysicist John Chambers models the dynamics of these newly found giant planetary systems to understand their formation history and to determine the best way to predict the existence and frequency of smaller Earth-like worlds.

As part of this research, Chambers explores the basic physical, chemical, and dynamical aspects that led to the formation of our own Solar System--an event that is still poorly understood. His ultimate goal is to determine if similar

Peter Driscoll studies the evolution of Earth’s core and magnetic field including magnetic pole reversal. Over the last 20 million or so years, the north and south magnetic poles on Earth have reversed about every 200,000, to 300,000 years and is now long overdue. He also investigates the Earth’s inner core structure; core-mantle coupling; tectonic-volatile cycling; orbital migration—how Earth’s orbit moves—and tidal dissipation—the dissipation of tidal forces between two closely orbiting bodies. He is also interested in planetary interiors, dynamos, upper planetary atmospheres and exoplanets—planets orbiting other stars. He uses large-

Alan Linde is trying to understand the tectonic activity that is associated with earthquakes and volcanos, with the hope of helping predictions methods.  He uses highly sensitive data that measures how the Earth is changing below the surface with devises called borehole strainmeters that measure tiny strains the Earth undergoes.

Strainmeter data has led to the discovery of events referred to as slow earthquakes that are similar to regular earthquakes except that the fault motions take place over much longer time scales. These were first detected in south-east Japan and have since been seen in a number of different environments including the San Andreas Fault in California and
