Planck 2015 results. I. Overview of products and scientific results
The European Space Agency's Planck satellite, dedicated to studying the early Universe and its subsequent evolution, was launched 14{\textasciitilde}May 2009and scanned the microwave andExpand
Ocean-like water in the Jupiter-family comet 103P/Hartley 2
It is reported that the D/H ratio in the Jupiter-family comet 103P/Hartley 2, which originated in the Kuiper belt, is (1.61 ± 0.24) × 10−4, which substantially expands the reservoir of Earth ocean-like water to include some comets, and is consistent with the emerging picture of a complex dynamical evolution of the early Solar System.

Localized sources of water vapour on the dwarf planet (1) Ceres
The detection of water vapour around Ceres is reported, with at least 1026 molecules being produced per second, originating from localized sources that seem to be linked to mid-latitude regions on the surface. Expand
New Millimeter Heterodyne Observations of Titan: Vertical Distributions of Nitriles HCN, HC3N, CH3CN, and the Isotopic Ratio 15N/14N in Its Atmosphere
High sensitivity observations were performed at 1.2- and 3-mm wavelengths with the IRAM 30-m telescope (Spain) between April 1996 and December 1999 to investigate the nitrile composition of Titan'sExpand
New molecules found in comet C/1995 O1 (Hale-Bopp) Investigating the link between cometary and interstellar material
We present millimetre and submillimetre observations of comet C/1995 O1 (Hale-Bopp) undertaken near perihelion with the Caltech Submillimeter Observatory and the 30-m telescope and Plateau-de-BureExpand
Evolution of the Outgassing of Comet Hale-Bopp (C/1995 O1) from Radio Observations
Spectra obtained from ground-based radio telescopes show the progressive release of CO, CH3OH, HCN, H2O (from OH), H2S, CS, H2CO, CH3CN, and HNC as comet Hale-Bopp (C/1995 O1) approached the sun fromExpand
Spectroscopic Monitoring of Comet C/1996 B2 (Hyakutake) with the JCMT and IRAM Radio Telescopes
Molecular radio lines were monitored in comet C/1996 B2 (Hyakutake) from 1996 February 10 to June 23, using the James Clerk Maxwell Telescope and the 30 m telescope and the Plateau de BureExpand
Radio wavelength molecular observations of comets C/1999 T1 (McNaught-Hartley), C/2001 A2 (LINEAR), C/2000 WM1 (LINEAR) and 153P/Ikeya-Zhang
We present a comparative study of the relative abundances of CO, CH 3 OH, H 2 CO, HCN, HNC, CS, H 2 S, CH 3 CN, SO and HNCO in comets C/1999 T1 (McNaught-Hartley), C/2001 A2 (LINEAR), C/2000 WM 1Expand
Ethyl alcohol and sugar in comet C/2014 Q2 (Lovejoy)
The detection of 21 molecules in comet C/2014 Q2 is reported, including the first identification of ethyl alcohol (ethanol, C2H5OH) and the simplest monosaccharide sugar glycolaldehyde (CH2OHCHO) in a comet, which supports the formation through grain-surface reactions in the solar system protoplanetary disk.
