Gravitational Waves
Presentation by Steve Kocsis
'Gravitational Waves' - Predicted by Einstein's general theory of relativity in 1916 but, not observed until 2015, gravitational waves are created by extremely dense objects - like neutron stars and black holes - orbiting in pairs. The dynamics of these objects distorts space-time, creating ripples that can be detected with sensitive instruments. Three American scientists received the 2017 Nobel prize in Physics for their roles in the discovery.

From Sojourner to Curiosity:  Twenty Years on Mars
Rosemary Walling, who teaches astronomy at UAS, will talk about Mars. She will explore what the Earth rovers - Spirit, Curiosity and Opportunity have to tell us about Mars. The exploration of Mars is the study of Mars by spacecraft. Probes from Earth, beginning in the late twentieth century, have yielded great increases in knowledge about Martian geology, dynamics and the possibility of Martian life.
Degenerate Stars
White Dwarfs, neutron stars, quark stars and black holes are the remains of stars after gravitational collapse. Very strange. A neutron star dice pair would weigh 2 billion tons. They have been observed from their light and gravitational waves.

Followed by ‘The Sky Tonight’ on the Spitz projector.
