Cassini detects interstellar dust grains The interstellar medium contains an array of small solid particles known as dust grains. Altobelli et al. used the dust analyzer on the Cassini probe to detect 36 interstellar dust grains as they passed by Saturn, and they measured the grains' elemental abundances. The results show that, remarkably, these grains lack carbon-bearing compounds and have been homogenized in the interstellar medium into silicates with iron inclusions. Science, this issue p… 
Investigating the interstellar dust through the Fe K-edge
Context. The chemical and physical properties of interstellar dust in the densest regions of the Galaxy are still not well understood. X-rays provide a powerful probe since they can penetrate gas and
Interstellar dust in the solar system: model versus in situ spacecraft data
Context. 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. Later on, interstellar
High Radiation Pressure on Interstellar Dust Computed by Light-Scattering Simulation on Fluffy Agglomerates of Magnesium-silicate Grains with Metallic-iron Inclusions
Recent space missions have provided information on the physical and chemical properties of interstellar grains such as the ratio $\beta$ of radiation pressure to gravity acting on the grains in
Silicon and iron dust in gamma-ray burst host galaxy absorbers
Depletion studies provide a way to understand the chemical composition of interstellar dust grains. We here examine 23 gamma-ray bursts (GRBs) optical afterglow spectra (spanning 0.6 ≤ z ≤ 5.0) and
Cosmic Dust IX
It is a dusty universe. Every year, approximately 104 tons of cosmic dust enter Earth’s atmosphere (Brownlee, 1985). These dust particles mostly originate from the breakup of comets and asteroids and

Interplanetary dust grains originate from a variety of source bodies, including comets, asteroids, and Edgeworth–Kuiper belt objects. Centaurs, generally defined as those objects with orbits that
Dust-depletion sequences in damped Lyman-α absorbers
Metals in the interstellar medium (ISM) of essentially all types of galaxies are observed to be depleted compared to the expected values. The depletion is most likely due to dust condensation in, for
Iron and silicate dust growth in the Galactic interstellar medium: clues from element depletions
The interstellar abundances of refractory elements indicate a substantial depletion from the gas phase, that increases with gas density. Our recent model of dust evolution, based on hydrodynamic

Iron is the only element that requires most of its growth to occur outside the traditional stellar condensation sources, and this is a robust statement that does not depend on the evolving understanding of the dust destruction efficiency in the ISM.
The Dawn of Dust Astronomy
We review the development of dust science from the first ground-based astronomical observations of dust in space to compositional analysis of individual dust particles and their source objects. A


Aspects of the mass distribution of interstellar dust grains in the solar system from in situ measurements
The in situ detection of interstellar dust grains in the solar system by the dust instruments on-board the Ulysses and Galileo spacecraft as well as the recent measurements of hyperbolic radar
Interstellar dust close to the Sun
The low density interstellar medium (ISM) close to the Sun and inside of the heliosphere provides a unique laboratory for studying interstellar dust grains. Grain characteristics in the nearby ISM
Dust in the local interstellar wind
The gas-to-dust mass ratios found for interstellar dust within the solar system, versus values determined astronomically for the cloud around the solar system, suggest that large and small
Composition, Structure, and Size Distribution of Dust in the Local Interstellar Cloud
The average properties of interstellar dust have previously been inferred from remote astronomical observations of interstellar extinction and from gas depletion measurements. In addition to recent
Evidence for interstellar origin of seven dust particles collected by the Stardust spacecraft
Seven particles captured by the Stardust Interstellar Dust Collector and returned to Earth for laboratory analysis have features consistent with an origin in the contemporary interstellar dust stream, and are diverse in elemental composition, crystal structure, and size.

Origins of GEMS Grains
Interplanetary dust particles (IDPs) collected in the Earth s stratosphere contain high abundances of submicrometer amorphous silicates known as GEMS grains. From their birth as condensates in the

The Cassini-Huygens Cosmic Dust Analyzer (CDA) is intended to provide direct observations of dust grains with masses between 10−19 and 10−9 kg in interplanetary space and in the jovian and saturnian
Interstellar Dust in the Solar System
A fraction of the dust in the interstellarmedium (ISM) enters the heliosphere and is measured in situ from spacecraft. This review surveys the in situ measurements and discusses a hence derived model
