Dr. Michael E. Summers speaks to the Northern Virginia Astronomy Club in June of 2021. The discovery of ‘Oumuamua (1I/2019/U1) represented our first detection of a solar system object with an origin that was definitely outside of our solar system. Its name comes from Hawaiian meaning “first messenger from afar” yet deciphering its message has proved difficult and controversial. ‘Oumuamua was discovered by the Pan-STARRS telescope at the Haleakala Observatory in Hawaii on October 19, 2017, when it had already made its closest approach to the Earth on a hyperbolic orbit that would carry it back into the interstellar medium from which it came. Although currently classified as an interstellar comet, it has characteristics completely unlike any known comet. Its unusual shape, lack of a coma, and the fact that it exhibited non-gravitational acceleration has made its classification a complex problem. This talk will cover what is known about ‘Oumuamua and various proposals for its origin, including the suggestion that it is a product of alien technology.

Dr. Andrea DuPree discusses The Mysterious Great Dimming of Betelgeuse. The bright cool supergiant Betelgeuse became historically faint a little over one year ago in early February 2020. Various explanations have been offered for its unusual behavior – including conjectures this foreshadows an imminent supernova event. Direct imaging, spatially resolved spectroscopy, polarization measures, infrared, optical and ultraviolet spectra and more help us to unravel what happened to the star. The current state of the star as well as new results from spectroscopic observations with HST will be reported in advance of the next optical minimum expected this spring.
