- Stardust comet dust resembles asteroid materials
01-24-2008 · EurekAlert!
Contrary to expectations for a small icy body, much of the comet dust returned by the Stardust mission formed very close to the young sun and was altered from the solar system's early materials.

- U of M physicist reads the history of the solar system in grains of comet dust
01-03-2008 · EurekAlert!
Four years ago, NASA's Stardust spacecraft chased down a comet and collected grains of dust blowing off its nucleus. When the spacecraft Comet Wild-2 returned, comet dust was shipped to scientists all over the world, including University of Minnesota physics professor Bob Pepin. After testing helium and neon trapped in the dust specks, Pepin and his colleagues report that while the comet formed in the icy fringes of the solar system, the dust appears to have been born close to the infant sun.

Our Solar System may have been created in a gigantic mixing process far more extensive than previously imagined, according to research published today.The findings, reported in the journal Science, come from the first analysis of dust fragments from Comet Wild-2, captured by NASA's Stardust spacecraft and brought to Earth in January 2006.

05-03-2007 · EurekAlert!
The ESA-NASA Solar and Heliospheric Observatory may have glimpsed long-sought oscillations on the sun's surface. The data will reveal details about the very core of our central star, and it contains clues as to how the sun formed, 4.6 billion years ago.

12-16-2006 · Science News Online
Just as the solar system was forming some 4.6 billion years ago, some of the hottest material, residing so close to the sun that it was almost vaporized, sped out to the chilliest reaches of deep space, where it became incorporated into comets.

The chemical fingerprint of a burned-out star indicates that Earth-like planets may not be rare in the universe and could give clues to what our solar system will look like when our sun dies and becomes a white dwarf star some five billion years from now.

- First Sunrise on Hinode's instruments
10-31-2006 · EurekAlert!
The Hinode (formerly Solar-B) satellite, a joint Japan/NASA/PPARC mission launched on 22nd September 2006, has today (October 31st) reported its first observations of the Sun with its suite of scientific instruments. The satellite was renamed "Hinode" which is Japanese for Sunrise, which is most appropriate since Hinode will watch at close hand massively explosive solar flares erupting from the Sun's surface and rising into interstellar space.

12-14-2006 · EurekAlert!
Stardust, the NASA spacecraft mission, was given that name in hopes that the seven-year journey to capture comet samples would bring back to Earth, well, stardust. In an article coming out in the December 15, 2006, issue of the journal Science, researchers at Washington University in St. Louis are the first to report that a sample they received from the mission actually does contain stardust -- particles that are older than the sun.
