Washington, DC—An ancient sliver of the building blocks from which comets formed was discovered encased inside a meteorite like an insect in amber by a Carnegie-led research team. The finding, published by Nature Astronomy, could offer clues to the formation and evolution of our Solar System.

Meteorites were once part of larger bodies, asteroids, which broke up due to collisions in space and survived the trip through the Earth’s atmosphere. Their makeup can vary substantially from meteorite to meteorite, reflecting their varying origin stories in different parent bodies that formed in different parts of the Solar System. Asteroids and comets both formed from the disk

Their work is published in The Astrophysical Journal Letters.

“It’s so exciting that TESS, which launched just about a year ago, is already a game-changer in the planet-hunting business,” said Teske, who is second author on the paper. “The spacecraft surveys the sky and we collaborate with the TESS follow-up

The five-year project seeks to uncover the conditions on early Earth that gave rise to life by identifying, replicating, and exploring how prebiotic molecules and chemical pathways could have formed under realistic early Earth conditions.

The evolution of planet Earth and the emergence of life during its first half-billion years are inextricably linked, with a series of planetwide transformations – formation of the ocean,

Scientists still aren't sure how this mountain grew inside of the crater, which has been a longstanding mystery. 

One idea is that sediment once filled Gale Crater and was then worn away by millions of years of wind and erosion, excavating the mountain. However, if the crater had been filled to the brim, the material on the bottom, which

Gravity, the fundamental force that shaped our planet, varies across the Earth’s surface, both from place to place and over time. For more than three centuries, scientists have made gravity measurements to define the shape of the Earth. Today, very precise measurements of gravity provide crucial information on the mass distribution and transport within the planet. In this talk, Dr. Le Mével will highlight the long history of the determination of the gravity field, from the first field expeditions to the era of satellite measurements, and will discuss the evolution of the instrumentation. She will then show how gravity studies are used to image magmatic systems under

In shock-wave experiments, high-powered lasers or guns are used to send a supersonic pressure wave through a sample. This type of dynamic compression can generate immense pressure and allows for the study of impact phenomena in real time. These experiments have wide applications for Earth and planetary science, ranging from understanding the effects of meteorite impacts to studying the structure of planetary interiors. Dynamic experiments are short-lived, generally having a duration of tens of billionths of a second. This requires the development of ultrafast experiments. In this talk, Tracy will review new results using high-intensity pulsed x-rays to examine the crystal structure of

Carnegie's Paul Butler has been leading work on a multiyear project to carry out the first reconnaissance of all 2,000 nearby Sun-like stars within 150 light-years of the solar system (1 lightyear is about 9.4 trillion kilometers). His team is currently monitoring about 1,700 stars, including 1,000 Northern Hemisphere stars with the Keck telescope in Hawaii and the UCO Lick Observatory telescope in California, and 300 Southern Hemisphere stars with the Anglo-Australian telescope in New South Wales, Australia. The remaining Southern Hemisphere stars are being surveyed with Carnegie's new Magellan telescopes in Chile. By 2010 the researchers hope to have completed their planetary

Carbon plays an unparalleled role in our lives: as the element of life, as the basis of most of society’s energy, as the backbone of most new materials, and as the central focus in efforts to understand Earth’s variable and uncertain climate. Yet in spite of carbon’s importance, scientists remain largely ignorant of the physical, chemical, and biological behavior of many of Earth’s carbon-bearing systems. The Deep Carbon Observatory (DCO) is a global research program to transform our understanding of carbon in Earth. At its heart, DCO is a community of scientists, from biologists to physicists, geoscientists to chemists, and many others whose work crosses these

High-elevation, low relief surfaces are common on continents. These intercontinental plateaus influence river networks, climate, and the migration of plants and animals. How these plateaus form is not clear. Researchers are studying the geodynamic processes responsible for surface uplift in the Hangay in central Mongolia to better understand the origin of high topography in continental interiors.

This work focuses on characterizing the physical properties and structure of the lithosphere and sublithospheric mantle, and the timing, rate, and pattern of surface uplift in the Hangay. They are carrying out studies in geomorphology, geochronology, thermochronology, paleoaltimetry,

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.

Roiling cauldrons of liquid-laden material flow within Earth’s rocky interior. Understanding how this matter moves and changes is essential to deciphering Earth’s formation and evolution as well as the processes that create seismic activity, such as earthquakes and volcanoes. Bjørn Mysen probes this hidden environment in the laboratory and, based on his results, models can help explain what goes on in this remote realm.

Mysen investigates changes in the atomic properties of molten silicates at high pressures and temperatures that pervade the interior Earth. Silicates comprise most of the Earth's crust and mantle. He uses devices, such as the diamond anvil

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-

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 Doppler velocities, from 300 meters per second in the 1980s to 1 meter a second in the 2010s to detect planets around other stars. The ultimate goal is to find planets that resemble the Earth.

Butler designed and built the iodine absorption cell system at Lick Observatory, which resulted in the discovery of 5 of the first 6 known extrasolar planets.  This instrument has become the de

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
