Haumea—one of the four known trans-Neptunian dwarf planets—is a very elongated and
rapidly rotating body 1 , 2 , 3 . In contrast to other dwarf planets 4 , 5 , 6 , its size, shape, albedo …

Context. Trans-Neptunian objects (TNO) represent the leftovers of the formation of the solar
system. Their physical properties provide constraints to the models of formation and …

We studied a sample of 93 asteroid pairs, ie, pairs of genetically related asteroids that are
on highly similar heliocentric orbits. We estimated times elapsed since separation of pair …

‘Lockdown’ periods in response to COVID-19 have provided a unique opportunity to study
the impacts of economic activity on environmental pollution (eg, NO 2 , aerosols, noise, light). …

A reassessment of ground‐based observations confirms to better than a 98% confidence
level that the Galileo probe entered a 5‐μm hot spot, a region of unusual clarity and dryness, …

We present results from the most comprehensive radio monitoring campaign towards the
closest star to our Sun, Proxima Centauri. We report 1.1–3.1 GHz observations with the …

We present a summary of the campaign of remote observations that supported the European
Space Agency's Rosetta mission. Telescopes across the globe (and in space) followed …

Combining stellar occultation observations probing Pluto’s atmosphere from 1988 to 2013,
and models of energy balance between Pluto’s surface and atmosphere, we find the …

The rotational states of the members in the dwarf planet-satellite systems in the trans-Neptunian
region are determined by formation conditions and the tidal interaction between the …

Context. The tenuous nitrogen (N 2 ) atmosphere on Pluto undergoes strong seasonal effects
due to high obliquity and orbital eccentricity, and has recently (July 2015) been observed …
