    Description: Deuterated water (HDO) was detected in comet C/1995 O1 (Hale-Bopp) with the use of the James Clerk Maxwell Telescope on Mauna Kea, Hawaii. The inferred D/H ratio in Hale-Bopp's water is (3.3 +/- 0.8) x 10(-4). This result is consistent with in situ measurements of comet P/Halley and the value found in C/1996 B2 (Hyakutake). This D/H ratio, higher than that in terrestrial water and more than 10 times the value for protosolar H2, implies that comets cannot be the only source for the oceans on Earth.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Meier, R -- Owen, T C -- Matthews, H E -- Jewitt, D C -- Bockelee-Morvan, D -- Biver, N -- Crovisier, J -- Gautier, D -- New York, N.Y. -- Science. 1998 Feb 6;279(5352):842-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉University of Hawaii, Institute for Astronomy, 2680 Woodlawn Drive, Honolulu, HI 96822, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9452379" target="_blank"〉PubMed〈/a〉
