We discuss the detailed composition of 28 extremely metal-poor (EMP) dwarfs, 22 of which are from the Hamburg/ESO Survey (HES), based on Keck echelle spectra. Our sample has a median [Fe/H] of - 2.7 ...

Debris dust in the habitable zones of stars-otherwise known as exozodiacal dust-comes from extrasolar asteroids and comets and is thus an expected part of a planetary system. Background flux from the ...

Marine oxygen-deficient zones represent a natural source of nitrous oxide (N2O), a potent greenhouse gas and ozone-depleting agent. To investigate controls on N2O production, the responses of ammonia ...

10.1111/j.1365-2966.2012.20586.x The presence of substructure in galaxy groups and clusters is believed to be a sign of recent galaxy accretion and can be used to probe not only the assembly history ...

From volcanic systems to distant worlds, we explore every scale of planetary science. Drawing on more than a century of scientific discovery, the Earth and Planets Laboratory is a multidisciplinary ...

Carnegie Science astronomers are advancing a new understanding of cosmic processes, from the synthesis of “star stuff”—the raw materials from which everything in the universe is constructed—to the ...

Washington, DC— Pairing cutting-edge chemistry with artificial intelligence, a multidisciplinary team of scientists found ...

From teeming biodiversity hotspots to inhospitable environments where resilient microorganisms thrive, life has reshaped our planet. What can it teach our researchers about searching for signs of life ...

How did we get here and are we alone? Working at the nexus of biology, Earth science, and astronomy, Carnegie Science investigators boldly traverse disciplinary boundaries to reveal the relationships ...

Our experts reveal how our planet formed, evolved, differentiated into layers and developed the interconnected system of dynamic processes that made it habitable and enabled life to arise and thrive.
