Join astronomer Simon Radford for a talk on submillimeter astronomy at 6 p.m. April 6 at the Visitor Information Station at the 9,200-foot level on Mauna Kea.
He will discuss the work being done at the Caltech Submillimeter Observatory on top of the mountain. Stargazing will follow the presentation until 10 p.m.
The Caltech Submillimeter Observatory can measure light at submillimeter wavelengths (longer than infrared and shorter than radio wavelengths), which is particularly important for the study of interstellar dust particles and molecular gas.
On the first Saturday of each month, a member of the Mauna Kea astronomy community shares research with the public. For more information, call 961-2180, or visit www.ifa.hawaii.edu/info/vis.
“Astronomers use the CSO to observe objects in our solar system, in our galaxy, and in galaxies across the universe,” said visitor station spokeswoman Janet Nathani.
