Speaking at a symposium titled "The Origin and Evolution of Planets" held at the annual meeting of the American Association for the Advancement of Science, two Carnegie Institution scientists will present their perspectives on the new era of planetary exploration.
Alan Boss of Carnegie's Department of Terrestrial Magnetism and author of the new book The Crowded Universe: The Search for Living Planets points out that evidence for all three classes of planets known in our Solar System—ice giants, gas giants, and terrestrial (rocky) planets—has been detected in extra-solar systems. "We already know enough now to say that the Universe is probably loaded with terrestrial planets similar to the Earth," he says. "We should expect that there are going to be many planets which are habitable, so probably some are going to be inhabited as well."
Boss expects that NASA's Kepler spacecraft, due to launch in early March and dedicated to searching for Earthlike planets, will put his ideas to the test.
Russell Hemley, director of Carnegie's Geophysical Laboratory, studies the fundamental physics and chemistry of materials under extreme conditions. Understanding how the chemical building blocks of planets, such as hydrogen, oxygen, silicon, iron, and other crucial elements such as carbon, respond to conditions in the deep interior of planets, where pressures can exceed those on the surface by factors of millions, is key to understanding how planets might form and evolve.
High-pressure studies can also offer clues to the search for life on planets different from our own. "Our work is uncovering not only exciting new physics and chemistry, but also new findings in biology that are relevant to the prospects for life in whatever form beyond the Earth," says Hemley. "Experiments are showing that there is viability of life as we know it now under surprisingly extreme conditions."

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
