Rescheduled – The Hawaiian Volcano Observatory on Uēkahuna: A Legacy of Science.
Perched high on the rim of Uēkahuna since the late 1940s, the Hawaiian Volcano Observatory has been the hub of research and monitoring of Hawaiian volcanoes. The Reginald T. Okamura Building, constructed in 1985 and the heart of the observatory, was damaged beyond repair during the earthquakes of 2018. Join Don Swanson, who has a 55-year association with the observatory, as he takes us through the science conducted at this remarkable facility and the legacy being carried into the future. Part of Hawai‘i Volcanoes’ ongoing After Dark in the Park programs and sponsored by the Friends of Hawaiʻi Volcanoes National Park. Free, but park entrance fees apply.

Invasive Wildlife of the Pacific Islands. The terrestrial biota of the Central Pacific is primarily defined by its degree of isolation. At the center are the Hawaiian Islands, almost 4,000 km (2,480 miles) from the closest continental land mass. Millions of years of evolutionary isolation created beautiful and unique native ecosystems. However, the Central Pacific islands were suddenly besieged by alien rodents, carnivores, ungulates, reptiles and diseases. Dr. Steven Hess, research biologist with the U.S. Dept. of Agriculture, reveals how reversing the devastating effects of alien species has proven to be difficult, but limited successes have resulted in the dramatic recovery of native species. Part of Hawai‘i Volcanoes’ ongoing After Dark in the Park programs and co-sponsored by the Friends of Hawaiʻi Volcanoes National Park. Free, but park entrance fees apply.
When: Sept. 12 at 7 p.m.

The Search for Exoplanets: Earth Like Planets and Alien Worlds. Orbiting distant stars, myriad alien worlds have recently been discovered.

Come learn about the hunt for planets around distant stars with Subaru Telescope astronomer Julien Lozi. Hear about the exoplanet revolution and what this means for the field of astronomy and how Hawaiʻi may be the perfect place for future discoveries.
