Understanding the region of interstellar space through which the solar system travels is no easy task. Interstellar space begins beyond the heliosphere, the bubble of charged particles surrounding the sun that reaches far beyond the outer planets. Voyager 1 has crossed into this space, but it’s difficult to gain a complete global picture from measurements in only one direction.
The water found locked inside soil on the moon's surface derives from hydrogen in the solar wind - meaning there could be water on other apparently-dry bodies in the solar system too.
Scientists from the UK's Rutherford Appleton Laboratory have made a discovery that could help future astronauts shelter from radiation on the moon.
A recent study by an international team of astronomers has determined that Earth's moon does indeed have a far-reaching, invisible influence on the Sun's solar wind.
In the mid-nineteenth century, one of the most massive stars in our Milky Way galaxy suddenly got much brighter. For ten years, indeed, it was the second-brightest star in the sky.
Solar storms and Coronal Mass Ejections (CMEs) are powerful enough to erode the surface of the moon, NASA simulations indicate.
ESA has recovered a crucial science package on its Cluster mission, using a series of commands invented for the occasion.
Our sun and its inner planets may not have formed from the same materials, as previously thought, samples returned by NASA’s Genesis mission indicate.
After 33 years' traveling, NASA's Voyager 1 spacecraft has reached the point at the edge of the solar system where the solar wind has died down.
The EU has agreed funding for a project to create the largest and fastest man-made craft in history.
NASA has given the green light to the development and 2013 launch of the Mars Atmosphere and Volatile Evolution (Maven) mission, which aims to investigate how Mars lost so much of its atmosphere.
In a project reminiscent of Prometheus' theft of fire from the gods, NASA's planning to dive into the sun and capture some of its atmosphere.
Lunar explorers may have another hazard to contend with - new calculations by NASA's Lunar Science Institute team indicate that the moon's polar craters may be charged to hundreds of volts.
Scientists can now listen to a set of solar wind data that's usually represented visually, as numbers or graphs.
