Earth & Planetary Science Stories
The world’s 2500 rarest minerals have now been categorised for the first time, revealing intriguing implications. Most have been formed in processes directly or indirectly related to living organisms...
Washington, D.C.—Earth's magnetic field is generated by the motion of liquid iron in the planet's core. This “geodynamo” occasionally reverses its polarity—the magnetic north and south poles swap...
Jackie Faherty talks to Runner's World about spotting Mercury, Venus, Mars, Saturn, and Jupiter during a single early morning run....
Through late February, five planets will align in early morning sky, and can be seen unaided. Jackie Faherty tells NPR it is like the planetary Academy Awards....
“It was probably the runt of the family,” Scott Sheppard tells the L.A. Times of the theorized ninth planet. Sheppard's 2014 co-discovery of the planetoid 2012 VP113, popularly nicknamed "Biden," ...
"Estimates range as high as there being one habitable Earth-like planet for every star in our galaxy. As someone who has lived through the ups and downs of the history of the field of planet...
Smithsonian Magazine talks Bob Hazen about "Life's Rocky Start" the NOVA special that features his work on mineral evolution and ecology. “We see this intertwined co-evolution of the geosphere and...
Washington, DC— A team made up almost entirely of current and former Carnegie scientists has discovered a highly unusual planetary system comprised of a Sun-like star, a dwarf star, and an...

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...
Established in June of 2016 with a generous gift of $50,000 from Marilyn Fogel and Christopher Swarth, the Marilyn Fogel Endowed Fund for Internships will provide support for “very young budding scientists” who wish to “spend a summer getting their feet wet in research for the very first time.” ...
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...
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...
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...
Geochemist Steven Shirey is researching how Earth's continents formed. Continent formation spans most of Earth's history, continents were key to the emergence of life, and they contain a majority of Earth’s resources. Continental rocks also retain the geologic record of Earth's ancient geodynamic...
