Juno is a PI-led mission to Jupiter, the second mission in NASA's New Frontiers Program.
The 3625-kg spacecraft spins at 2 rpm and is powered by three 9-meter-long solar arrays …

Hydrogen and helium are the most abundant elements in the Universe. They are also, in
principle, the most simple. Nonetheless, they display remarkable properties under extreme …

The masses and radii of exoplanets are fundamental quantities needed for their
characterisation. Studying the different populations of exoplanets is important for …

The Juno spacecraft has measured Jupiter's low‐order, even gravitational moments, J2–J8,
to an unprecedented precision, providing important constraints on the density profile and …

PLATO 2.0 has recently been selected for ESA's M3 launch opportunity (2022/24). Providing
accurate key planet parameters (radius, mass, density and age) in statistical numbers, it …

INTRODUCTION The interior structure of Saturn, the depth of its winds, and the mass and
age of its rings have been open questions in planetary science. The mass distribution inside …

Population studies of exoplanets are key to unlocking their statistical properties. So far, the
inferred properties have been mostly limited to planetary, orbital, and stellar parameters …

The composition of a planet's atmosphere is determined by its formation, evolution, and
present-day insolation. A planet's spectrum therefore may hold clues on its origins. We …

The best constraints on the internal structures of giant planets have historically originated
from measurements of their gravity fields,–. These data are inherently mostly sensitive to a …

Jupiter's atmosphere is rotating differentially, with zones and belts rotating at speeds that
differ by up to 100 metres per second. Whether this is also true of the gas giant's interior has …
