Meteorites from Mars and on Mars

Location: Geology 3656
Time: 2:30PM

Martian meteorites are key sources of information about the Red Planet, especially its volcanic history. Ar and N isotopic ratios show the martian connection. Even though there are fewer martian meteorites (about 110) than lunar meteorites (140), the tally for meteorite falls is 5 martians to zero lunars. Rovers have analyzed a few meteorites among the cobbles on the martian surface. Photo credit: NASA/JPL-Caltech/LANL/CNES/IRAP/LPGNantes/CNRS/IAS/MSSS




Solar Eclipse watching event

Astronomy and Planetary Science

Location: Court of Sciences
Time: 9:30AM

People in Los Angeles will be able to see a partial solar eclipse, as long as clouds do not obstruct the view. UCLA’s public event will be run from 9:30 to 11:30 a.m. on Monday, Aug. 21. The maximum point of the eclipse will be at 10:20 a.m., when the moon will obscure about 60 percent of the sun. At 11:44 a.m., the moon will complete its journey across the sun. The event will be held at the campus’s Court of Sciences. UCLA will have specially filtered solar telescopes that protect the eyes while revealing stunning details of the sun, such as enormous clouds of ejected solar material, and surface features such as sunspots, which can be larger than the Earth. There will also be live images of the solar eclipse projected onto a white screen that will enable participants to take eclipse photos. UCLA scientists in astronomy and planetary sciences will be available to answer questions about the sun, the eclipse, the solar system and astronomy. A limited number of eclipse glasses will be provided. More info can be found here: Photo: NASA
