Comet samples returned to Earth by the NASA Stardust mission have provided a surprising
glimpse into the nature of early Solar System materials and an epiphany on the origin of the …

The Stardust spacecraft collected thousands of particles from comet 81P/Wild 2 and returned
them to Earth for laboratory study. The preliminary examination of these samples shows that …

Deep Impact collided with comet Tempel 1, excavating a crater controlled by gravity. The
comet's outer layer is composed of 1-to 100-micrometer fine particles with negligible …

Context. The complex shape of comet 67P and its oblique rotation axis cause pronounced
seasonal effects. Irradiation and hence activity vary strongly. Aims. We investigate the …

Images taken by the Stardust mission during its flyby of 81P/Wild 2 show the comet to be a 5-
kilometer oblate body covered with remarkable topographic features, including unusual …

Dust is an important constituent of cometary emission; its analysis is one of the major
objectives of ESA's Rosetta mission to comet 67P/Churyumov-Gerasimenko (C–G). Several …

Context. Dust jets (ie, fuzzy collimated streams of cometary material arising from the
nucleus) have been observed in situ on all comets since the Giotto mission flew by comet …

We report new light curves and phase functions for nine Jupiter-family comets (JFCs). They
were observed in the period 2004–2015 with various ground telescopes as part of the …

We present measurements of the dust particle flux and mass distribution from the Stardust
Dust Flux Monitor Instrument (DFMI) throughout the flyby of comet 81P/Wild 2. In the particle …

This revised edition places a unique emphasis on all the new results from ground-based,
satellites and space missions? detection of molecule H2 and prompt emission lines of OH …
