Large satellite constellations in low-Earth orbit seek to be the infrastructure for global broadband Internet and other telecommunication needs. We briefly review the impacts of satellite constellations on astronomy and show that the Internet service offered by these satellites will primarily target populations where it is unaffordable, not needed

The PRIMitive Asteroid Spectroscopic Survey (PRIMASS) was formed with the goal of determining the origins and likely compositions of mission targets (101955) Bennu and (162173) Ryugu. Both Bennu and Ryugu are thought to have originated from primitive asteroid populations in the inner main belt (IMB), specifically from the low inclination (i<8°)

Bennu's and Ryugu's top shapes, which exhibit oblate shapes with equatorial ridges, are considered to have evolved by fast rotation in a longer timescale after the reaccumulation-driven formation. Analyses have suggested different evolution processes that enhanced their top shapes. Bennu's shape may have been driven by surface processing, while

Due to their ubiquity and very long main-sequence lifetimes, abundance determinations in M dwarfs provide a powerful and alternative tool to GK dwarfs to study the formation and chemical enrichment history of our Galaxy. In this study, abundances of the neutron-capture elements Rb, Sr, and Zr are derived, for the first time, in a sample of nearby M

We present the discovery and characterisation of two transiting planets observed by the Transiting Exoplanet Survey Satellite (TESS) orbiting the nearby (d ⋆ ≈ 22 pc), bright (J ≈ 9 mag) M3.5 dwarf LTT 3780 (TOI-732). We confirm both planets and their association with LTT 3780 via ground-based photometry and determine their masses using precise

In 2033, after a 12-year trip across the Solar System, NASA's Lucy mission will arrive at the Patroclus─Menoetius binary system, in Jupiter's L5 cloud. On its way, Lucy will visit one asteroid and seven Jupiter Trojans, all of them primitive asteroids. Lucy's foreseen discoveries about the surface geology, color, and composition of these Trojans
