This review presents our understanding of cometary dust at the end of 2017. For decades,
insight about the dust ejected by nuclei of comets had stemmed from remote observations …

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 …

Aerogel technology provides high added-value lightweight materials with outstanding
textural properties (ie, high surface area and open porosity). Aerogels are obtained from wet …

The Philae lander provides a unique opportunity to investigate the internal structure of a
comet nucleus, providing information about its formation and evolution in the early solar …

Before Rosetta, the space missions Giotto and Stardust shaped our view on cometary dust,
supported by plentiful data from Earth based observations and interplanetary dust particles …

The nature of organic matter in meteorites reveals information about early solar system
chemistry and the histories of parent bodies as recorded in the effects of physical and …

Silica aerogels are unique porous materials possessing high visible-light transparency and
low thermal conductivity. However, the practical applications are limited due to the native …

As an attractive collector medium for hypervelocity particles, combined with outstanding
physical properties and suitable compositional characteristics, SiO2 aerogel has been …

When comet nuclei approach the Sun, the increasing energy flux through the surface layers
leads to sublimation of the underlying ices and subsequent outgassing that promotes the …

The fractal dust particles observed by Rosetta cannot form in the physical conditions
observed today in comet 67P/Churyumov-Gerasimenko (67P hereinafter), being instead …
