Interstellar interlopers are bodies formed outside of the Solar System but observed passing
through it. The first two identified interlopers, 1I/'Oumuamua and 2I/Borisov, exhibited …

A detailed overview of the knowledge gaps in our understanding of the heliospheric
interaction with the largely unexplored Very Local Interstellar Medium (VLISM) are provided …

Dust is a ubiquitous feature of the cosmos, impinging directly or indirectly on most fields of
modern astronomy and astrophysics. Dust in the Galactic Environment, Second Edition …

In the early solar nebula, the formation of planetesimals and cometesimals is believed to be
due to inelastic collisions of initially micron-sized grains. The collisions are caused by …

ABSTRACT A direct measurement of the extragalactic background light (EBL) can provide
important constraints on the integrated cosmological history of star formation, metal and dust …

We present an improved model for interplanetary dust grain fluxes in the outer Solar System
constrained by in situ dust density observations. A dynamical dust grain tracing code is used …

In a deep ocean ferromanganese crust an excess of 60 Fe radioactivity was measured by
means of high sensitivity accelerator mass spectrometry. The enhanced concentrations …

Stardust, the 4th Discovery mission launched in February 1999, will collect coma samples
from the recently deflected comet 81P/Wild 2 on 2 January 2004 and return them to Earth on …

The atmospheres of the giant planets are reducing, being mainly composed of hydrogen,
helium and methane. But the rings and icy satellites that surround these planets, together …

Interplanetary dust particles and meteoroids mostly originate from comets and asteroids.
Understanding their distribution in the Solar system, their dynamical behavior and their …
