Abstract The Zwicky Transient Facility (ZTF), a public–private enterprise, is a new time-
domain survey employing a dedicated camera on the Palomar 48-inch Schmidt telescope …

Objects in the Kuiper belt are difficult to study in detail, even with the best telescopes
available. Therefore, for many years, studies of the compositions of these objects were …

Over the past three decades, we have witnessed one of the great revolutions in our
understanding of the cosmos—the dawn of the Exoplanet Era. Where once we knew of just …

Abstract The Lucy Mission is a NASA Discovery-class mission to send a highly capable and
robust spacecraft to investigate seven primitive bodies near both the L 4 and L 5 Lagrange …

Interstellar comets penetrating through the Solar System had been anticipated for decades,.
The discovery of asteroidal-looking 'Oumuamua, was thus a huge surprise and a puzzle …

During its approach to asteroid (101955) Bennu, NASA's Origins, Spectral Interpretation,

Most comets are volatile-rich bodies that have recently entered the inner solar system
following long-term storage in the Kuiper belt and the Oort cloud reservoirs. These reservoirs …

The primordial disc of small icy planetesimals, once located at 15–from the Sun, was
disrupted by giant planet migration in the early Solar system. The primordial disc thereby …

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 …

We present new optical coronagraphic data of Fomalhaut obtained with HST/STIS in 2010
and 2012. Fomalhaut b is recovered at both epochs to high significance. The observations …
