Ocean-like water in the Jupiter-family comet 103P/Hartley 2

Hartogh, Paul; Bergin, Edwin A.; Blake, Geoffrey A. +10 more

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 bulk composition to that of meteorites known as enstatite chondrites suggests a dry proto-Earth with subsequent delivery of volatiles by local accretion …

Submillimetre galaxies reside in dark matter haloes with masses greater than 3×10¹¹ solar masses

Altieri, B.; Aussel, H.; Elbaz, D. +71 more

The extragalactic background light at far-infrared wavelengths comes from optically faint, dusty, star-forming galaxies in the Universe with star formation rates of a few hundred solar masses per year. These faint, submillimetre galaxies are challenging to study individually because of the relatively poor spatial resolution of far-infrared telesco…
