Titan is the only moon with a substantial atmosphere, the only other thick N2 atmosphere
besides Earth's, the site of extraordinarily complex atmospheric chemistry that far surpasses …

The relative proportion of the two isotopes of nitrogen, 14N and 15N, varies dramatically
across the Solar System, despite little variation on Earth. NASA's Genesis mission directly …

Primitive objects like comets hold important information on the material that formed our solar
system. Several comets have been visited by spacecraft and many more have been …

The ice giants Uranus and Neptune are the least understood class of planets in our solar
system but the most frequently observed type of exoplanets. Presumed to have a small rocky …

INTRODUCTION Past remote observations of Saturn by Pioneer 11, Voyager 1 and 2, Earth-
based observatories, and the Cassini prime and solstice missions suggested an inflow of …

Global maps of Jupiter's atmospheric temperatures, gaseous composition and aerosol
opacity are derived from a programme of 5–20 µm mid-infrared spectroscopic observations …

Brown dwarfs serve as ideal laboratories for studying the atmospheres of giant exoplanets
on wide orbits, as the governing physical and chemical processes within them are nearly …

Context. The region around the H 2 O ice line, due to its higher surface density, seems to be
the ideal location to form planets. The core of Jupiter, as well as the cores of close-in gas …

The apparition of bright comets C/2012 F6 (Lemmon) and C/2014 Q2 (Lovejoy) in March-
April 2013 and January 2015, combined with the improved observational capabilities of …

Context. Reconciling models of Jupiter's interior with measurements of the atmospheric
composition still poses a significant challenge. Interior models favour a subsolar or solar …
