Scientists at NASA reveal a new understanding of the mysterious mechanism responsible for heating the outer part of the solar atmosphere, the corona, to million degree temperatures.

Using data from NASA’s New Horizons spacecraft and two telescopes at Earth, an international team of scientists has found that one of the solar system’s largest and newest storms – Jupiter’s Little Red Spot – has some of the highest wind speeds ever detected on any planet.

Scientists from the University of Maryland and the Max-Planck Institute for Solar System Research in Germany appear to have solved a long-standing mystery about the cause of anomalies in Jupiter's gossamer rings.

Data from the ESA/NASA spacecraft SOHO shows clearly that powerful starquakes ripple around the Sun in the wake of mighty solar flares that explode above its surface. The observations give solar physicists new insight into a long-running solar mystery and may even provide a way of studying other stars.

New insights into solar activity have been revealed thanks to research from a group of Cambridge academics.

Using visible and infrared data collected from telescopes on Hawaii’s Mauna Kea, a team of scientists, led by the University of Maryland’s Jessica Sunshine, have identified three asteroids that appear to be among our Solar System’s oldest objects.

For the first time ever, astronomers using the Hubble space telescope have discovered the presence of the organic molecule methane in the atmosphere around a planet outside our solar system. While astronomers say there's no chance that life exists on the exosolar planet, methane is essential for life, opening up the possibility that there could be life somewhere else in the universe.

A bookseller is offering a rare first edition of Nicolaus Copernicus' revolutionary book on the solar system at a Tokyo fair.

Harnessing Lawrence Livermore’s pioneering work in gravitational microlensing, supercomputer modeling and adaptive optics, scientists have found two planets in a solar system much like our very own.

Scaled versions of Jupiter and Saturn orbiting a star 5000 light-years away, half as massive as the Sun, have been revealed from an effort involving a world-wide net of telescopes, including the UK's Liverpool Telescope on the Canary Islands.

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.

A team of international astronomers reports in the Feb. 15 issue of Science the discovery of a solar system nearly 5,000 light years away with scaled-down versions of Jupiter and Saturn. Their findings suggest our galaxy could conceivably contain many star systems similar to our own. The National Science Foundation (NSF) sponsored the research.
