We review the current knowledge and understanding of dust in the inner solar system. The
major sources of the dust population in the inner solar system are comets and asteroids, but …

Radio-metric Doppler tracking data received from the Pioneer 10 and 11 spacecraft from
heliocentric distances of 20–70 AU has consistently indicated the presence of a small …

A collection is made of presently unexplained phenomena within our solar system and in the
universe. These phenomena are (1) the Pioneer anomaly,(2) the flyby anomaly,(3) the …

A fraction of the dust in the interstellar medium (ISM) enters the heliosphere and is
measured in situ from spacecraft. This review surveys the in situ measurements and …

Cosmic dust particles are small solid objects observed in the solar planetary system and in
many astronomical objects like the surrounding of stars, the interstellar and even the …

Dust particles in space often grow by mutual collisions and appear to be an agglomeration
of individual grains, the morphology of which can be described by the concept of fractals. In …

In the early 1990s, contemporary interstellar dust penetrating deep into the heliosphere was
identified with the in situ dust detector on board the Ulysses spacecraft. Between 1992 and …

We study the prospects for life on planets with subsurface oceans, and find that a wide range
of planets can exist in diverse habitats with ice envelopes of moderate thickness. We …

Interstellar material (ISMa) is observed both inside and outside of the heliosphere. Relating
these diverse sets of ISMa data provides a richer understanding of both the interstellar …

Observationally derived gas-phase abundances and appropriate assumptions for the total
elemental abundances of dust and gas determine the elemental composition of dust and the …
