Scientists for the first time have observed elusive oscillations in the Sun's corona, known as Alfven waves, that transport energy outward from the surface of the Sun. 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.

A year after launch, scientists working with Hinode, a Japanese mission with ESA participation, are meeting at Trinity College, Dublin, to discuss latest findings on solar mysteries - including new insights on solar flares and coronal heating.

Earth’s surface is a very active place; its plates are forever jiggling around, rearranging themselves into new configurations. Continents collide and mountains arise, oceans slide beneath continents and volcanoes spew.

Earth’s surface is a very active place; its plates are forever jiggling around, rearranging themselves into new configurations. Continents collide and mountains arise, oceans slide beneath continents and volcanoes spew. As far as we know Earth’s restless surface is unique to the planets in our solar system. So what is it that keeps Earth’s plates oiled and on the move?

A planet orbiting a giant red star has been discovered by an astronomy team led by Penn State's Alex Wolszczan, who in 1992 discovered the first planets ever found outside our solar system.

An international team of astronomers using NASA’s Swift satellite and the Japanese/U.S. Suzaku X-ray observatory has discovered a new class of active galactic nuclei (AGN).

Frigid geysers spewing material up through cracks in the crust of Pluto’s companion Charon and recoating parts of its surface in ice crystals could be making this distant world into the equivalent of an outer solar system ice machine.

Water has been discovered on a planet outside our solar system for the first time - giving scientists a tantalising hint of life existing beyond the Earth.

Scientists report the first conclusive discovery of the presence of water vapour in the atmosphere of a planet beyond our Solar System.

NASA will launch Phoenix spacecraft in August to uncover Mars’s mystery. Astronauts will dig planet’s surface hoping to find underground ice.

Dawn’s asteroid mission to Vesta and Ceres is delayed. The spacecraft launch now is scheduled for September.

NASA plans to launch a mission to the two asteroids that are between Mars and Jupiter this Sunday.
