Context. Water is a key molecule in the physics and chemistry of star and planet formation,
but it is difficult to observe from Earth. The Herschel Space Observatory provided …

For decades, the source of Earth's volatiles, especially water with a deuterium-to-hydrogen
ratio (D/H) of (1.558±0.001)× 10− 4, has been a subject of debate. The similarity of Earth's …

We present the scientific program of the Spectr-M project aimed at the creation and
operation of the Millimetron Space Observatory (MSO) planned for launch in the late 2020s …

In this paper, we review the scientific aspects of planetary space weather at different regions
of our Solar System, performing a comparative planetology analysis that includes a direct …

The D/H ratio in cometary water is believed to be an important indicator of the conditions
under which icy planetesimals formed and can provide clues to the contribution of comets to …

Herschel-PACS measurements of the rotational R (0) and R (1) HD lines in the atmospheres
of Uranus and Neptune are analyzed to derive a D/H ratio with improved precision for the …

We present Herschel observations of water isotopologues in the atmosphere of the Jupiter-
family comet 45P/Honda–Mrkos–Pajdušáková. No HDO emission is detected, with a 3σ …

Abstract On 2007 December 16–17, spectra were acquired of the disk of Uranus by the
Spitzer Infrared Spectrometer (IRS), ten days after the planet's equinox, when its equator …

Earth-and space-based observations provide synergistic information for space mission
encounters by providing data over longer timescales, at different wavelengths and using …

Cryovolcanic activity near the south pole of Saturn's moon Enceladus produces plumes of H
2 O-dominated gases and ice particles, which escape and populate a torus-shaped cloud …
