Studying Space Water: Measurements of the D/H Ratio in Comet 45P
This paper describes the measurement of the deuterium-to-hydrogen (D/H) ratio in a Jupiter-family comet, 45P. This ratio is related to the formation history of the comet and helps inform our understanding of the formation of our solar system.
Do Fast Radio Bursts come from neutron star mergers?
Recently, a population of short (a few micro-seconds) and energetic radio bursts were identified at cosmological distances. Today’s paper hypothesizes that these “Fast Radio Bursts” may be created in the final moments of a neutron star merger.
