Latest STEREO Stories
NASAâ€™s Dawn spacecraft, designed to complete a year-long study of the asteroid Vesta, made its first detailed observations of the surface on Thursday from a distance of 1,700 miles.
Those who study the sun face an unavoidable hurdle in their research â€“ their observations must be done from afar. Relying on images and data collected from 90 million miles away, however, makes it tough to measure the invisible magnetic fields sweeping around the sun.
2 probes, repositioned from THEMIS mission, will map surface magnetic fields.
The far side unveiled! This is the first complete image of the solar far side, the half of the sun invisible from Earth.
MESSENGERâ€™s Mercury Laser Altimeter (MLA) in its first 2 months of operation has already built up a grid of ground tracks that span most of Mercuryâ€™s surface north of the equator.
The largest disturbances to the Earth's geomagnetic environment occur when it is buffeted by solar material hurled in our direction by explosive changes in the Sun's atmosphere.
Researchers have discovered 122 new eclipsing binary stars and observed hundreds more variable stars in an innovative survey using NASA's two STEREO solar satellites.
On April 4th, MESSENGER began its yearlong science campaign to understand the innermost planet.
Observers say that the Sun has unleashed its strongest flare in four years.
On Feb 6th, NASA's twin STEREO probes moved into position on opposite sides of the sun, and they are now beaming back uninterrupted images of the entire starâ€”front and back.
