NASA is exploring options for innovative and imaginative uses of two large space telescopes recently transferred to the agency. In a request for information (RFI) published Monday, NASA seeks information about system concepts and architectures that would take advantage of these assets to address NASA's goals in astrophysics, heliophysics, planetary sciences, and human spaceflight.

An international team led by researchers from the University of Warwick and Oxford University is now dealing with unexpected results of an experiment with strongly heated graphite (up to 17,000 degrees Kelvin). The findings may pose a new problem for physicists working in laser-driven nuclear fusion and may also lead astrophysicists to revise our understanding of the life cycle of giant planets and stars.

Scientists have compared cycles of solar magnetic activity over the past 10,000 years - as reconstructed from ice cores - with the action of the planets. The agreement observed is very striking, raising hopes that our ability to forecast periods of intense solar activity may ultimately be improved.

Using ESA's Herschel space observatory, astronomers have discovered vast comet belts surrounding two nearby planetary systems known to host only Earth-to-Neptune-mass worlds. The comet reservoirs could have delivered life-giving oceans to the innermost planets.

A team of scientists studied the hydrogen in water from the Martian interior and found that Mars formed from similar building blocks to that of Earth, but that there were differences in the later evolution of the two planets. This implies that terrestrial planets, including Earth, have similar water sources - chondritic meteorites.

The mantles of Earth and other rocky planets are rich in magnesium and oxygen. Due to its simplicity, the mineral magnesium oxide is a good model for studying the nature of planetary interiors. New work from a team led by Carnegie's Stewart McWilliams studied how magnesium oxide behaves under the extreme conditions deep within planets and found evidence that alters our understanding of planetary evolution.

Astronomers have gotten a first look at the aftermath of Saturn's 'Great Springtime Storm' thanks to the heat-seeking capabilities of the international Cassini spacecraft and two ground-based telescopes. Even though the cosmic event is hidden to the naked eye, a giant oval vortex continues to exist long after the visible effects of the storm have subsided.

The search for a mysterious subatomic particle can certainly involve some enormous tools, not to mention a multitude of scientists. The effort to find the elusive "Higgs boson" includes over 5,800 scientists from 56 countries. It's a subatomic particle that gives other particles, such as quarks and electrons, their mass.
