Adam Sarafian, Graduate student , MIT/Woods Hole
Oceanographic Institute
"How Did the Earth Get its Ocean?"
This is a very old question. Two theories exist. Either our water came from
inside the Earth, stored during its early formation or the water came from
comets or other wet bodies hitting the Earth much later in its history.
Oddly enough, the answers lay in solid rocks and not our liquid water. The
team at the Institute have obtained and extracted evidence from rare samples
of ancient meteorites that have fallen to Earth. Adam and his colleagues
have analyzed the isotopic ratios of Hydrogen in these rocks, as this ratio
varies in different parts of the solar system. We will find out how this
difficult analysis was conducted and what answers it has uncovered.
9:00 PM Observing the skies through the 138 year old 8"
Alvan Clark Refractor at Seagrave.
In June, the planet Saturn will be well-placed
for observing.
