UTSA 'Friday Nights, Celestial Lights' event features Voyager 1 on Sept. 20
(Sept. 17, 2013) -- UTSA faculty astronomers invite the community to attend "Friday Nights, Celestial Lights," featuring Eric Schlegel, UTSA Vaughan Family Professor of Physics and Astronomy. Free and open to the public, the family-friendly astronomy event is 7:30 p.m., Friday, Sept. 20 in Science Building Room 2.02.02 on the UTSA Main Campus.
Schlegel will discuss media reports of Voyager 1 leaving the solar system, when in fact it has only left the heliosphere, the volume influenced by the sun's radiation. Schlegel's presentation will explore the boundary of our solar system, and offer an explanation for the definitive announcement last week about Voyager 1.
Following Schlegel's 40-minute presentation, and weather permitting, attendees can view the night sky using UTSA's telescopes including a 15-inch telescope and several 8-inch Cassegrain telescopes. Telescope viewing will be on the fourth-floor patio of the Flawn Science Building, which is wheelchair accessible. Saturn, the Ring Nebula and possibly Venus will be visible.
The UTSA Department of Physics and Astronomy hosts "Friday Nights, Celestial Lights" on the third Friday of each month when classes are in session. The programs are regularly updated on the "UTSA Astronomy" Facebook page. The next program is Friday, Oct. 18.
"Friday Nights, Celestial Lights" lectures and viewings began in 2009 as a celebration of the International Year of Astronomy, commemorating the 400th anniversary of Galileo Galilei using a telescope to observe the heavens.
