Climate catastrophes in the Solar System
04-26-2007 · European Space Agency (ESA)Earth sits between two worlds that have been devastated by climate catastrophes. In the effort to combat global warming, our neighbours can provide valuable insights into the way climate catastrophes affect planets.

- Something new under the Sun
01-30-2007 · EurekAlert!
That plants grow better if grown in a greenhouse in the correct climate is nothing new. Dutch researcher Rachel van Ooteghem has designed a control system for an improved solar greenhouse that yields more. In the new greenhouse, good climate control with sustainable energy resulted not only in an increased crop yield but also a lower gas bill.

- Extrasolars' light guides atmosphere research
02-21-2007 · Massachusetts Institute of Technology (MIT)
So far, astronomers have discovered about 200 planets outside our solar system, known as "extrasolar" planets. Very little is known about most of them, but for the first time, scientists have obtained new information about the atmospheres of two such planets.

06-26-2007 · EurekAlert!
Christopher Russell, UCLA professor of geophysics and space physics, is principal investigator on NASA's Dawn mission to the doughnut-shaped asteroid belt between Mars and Jupiter. Dawn is scheduled to launch July 7 from Cape Canaveral. Dawn will conduct a detailed study of the structure and composition of two of the first bodies formed in our solar system: the "dwarf planet" Ceres and the massive asteroid Vesta.

- Scientists find elusive waves in sun's corona
08-30-2007 · EurekAlert!
Scientists for the first time have observed elusive oscillations in the sun's corona, known as Alfvйn waves. The discovery is expected to give researchers more insight into the fundamental behavior of solar magnetic fields, eventually leading to a fuller understanding of how the sun affects Earth and the solar system.

- Astronomers discover scaled-down Jupiter and Saturn in a faraway solar system like our own
02-14-2008 · EurekAlert!
An international team of astronomers has discovered two planets that resemble smaller versions of Jupiter and Saturn in a solar system nearly 5,000 light years away. The find suggests that our galaxy hosts many planetary systems like our own, said Scott Gaudi, assistant professor of astronomy at Ohio State University.

- Ancient climate change may portend toasty future
12-07-2006 · EurekAlert!
Scientists, including Ken Caldeira of the Carnegie Institution's Department of Global Ecology, have found that the Earth's global warming, 55 million years ago, may have resulted from the climate's high sensitivity to a long-term release of carbon. This finding contradicts the position held by many climate-change skeptics that the Earth system is resilient to such emissions.

- Changes in west coast marine ecosystems significant
02-16-2007 · EurekAlert!
The California Current system has experienced significant changes during the past decade, resulting in dramatic variations in the ecosystem, characterized by shifts in phytoplankton production, expanding hypoxic zones, and the collapse of marine food webs off the western coast of the United States. These changes, driven by new wind patterns, are consistent with predictive models of global climate change.

- New Developments in "Artificial Photosynthesis"
03-27-2007 · Brookhaven National Laboratory
Scientists at Brookhaven are trying to design catalysts inspired by photosynthesis, the natural process by which green plants convert sunlight, water, and carbon dioxide into oxygen and carbohydrates. The goal is to design a bio-inspired system that can produce fuels like methanol, methane, and hydrogen directly from water and carbon dioxide using renewable solar energy.
