Observing Lab: Star Death Robert Ferguson Observatory

Saturday September 16th - 7:00pm

Sept. 16, 7 p.m.

Stars are giant balls of gas so massive that their internal pressures and temperatures result in sustained nuclear fusion that generates tremendous amounts of energy. On Sept. 16, the observatory will host a special Observing Lab on “Star Death: The End of Stellar Fusion.” This lab will examine what happens when stars exhaust their nuclear fuel, observing the various sorts of remnants different types of stars leave behind, from white dwarves to black holes.

Observing Labs provide a night of intensive telescope observing devoted to a single topic. Attendance is limited to 10 participants. Each attendee will get lots of eye time at several observatory telescopes, with an annotated observing list of the targeted objects, guidance from the docents operating the scopes, a brief presentation explaining the night’s topic, and more.

The lab begins at 7 p.m. Cost is $30. Buy tickets at, search “observatory.”
