  1. 1st Extra credit event Frontiers of Astronomy Community Event "Clearing Our View of the Universe with Robo-AO," ChristophBaranec(UHIfA) Wednesday, October 8, 2014, 7:30 p.m., UH Mānoa Art Building Auditorium (room 132). Free Admission When we peer out into the Universe with ground-based optical and infrared telescopes, Earth's atmosphere limits the clarity of our vision. Adaptive optics (AO) systems counteract the blurring effects of the atmosphere and greatly increase the acuity of our observations. In this talk, Dr. Baranec will review the technology behind adaptive optics and talk about the world's first fully automated laser adaptive optics instrument, Robo-AO. Dr. Baranec joined the faculty at the University of Hawai‘i's Institute for Astronomy in 2013. He is interested in pushing the limits of adaptive optics technology to shorter wavelengths, wider fields, and greater sky coverage, with the ultimate goal of broadening our understanding of the Universe through high-resolution imaging. His awards include a research fellowship from the Alfred P. Sloan Foundation (2014).

  2. Up Next: No readings associated with this, but we will be getting to Chapter 6 sometime next week Modern Astronomy in Hawaiÿi (European astronomy thatis… not the so-called “ancient” astronomy of the Kanaka Maoli)

  3. Captain Cook How ancient is ancient? Actually, we’re only talking about ~125 years ago (about 6 generations…

  4. European Astronomy in Hawaiÿi began with the transit of Venus • Transits of Venus = very rare: • Currently happen in pairs, 8 years apart, which repeat onlyafter more than a century • Some transit pairs are: • 1761 & 1769 • 1874 & 1882 • 2004 & 2012

  5. Captain James …

  6. Captain James Kirk (stardate ?) To boldly split infinitives like no man before

  7. Captain James Cook (1728-1779) In 1768 the Royal Society of London sent a ship to the south pacific to establish an astronomical observatory for the viewing of Venus in transit across the Sun. Captained by 1st Lieutenant James Cook, the flat-bottomed ship and its crew of 94 men were sent out by the Admiralty of King George III officially to observe the transit of Venus from King George’s Island (Tahiti). Unofficially however, they were to search between Tahiti and New Zealand for ‘a Continent or Land of great extent’, which may ‘redound greatly to the Honour of this Nation as a Maritime Power, as well as to the Dignity of the Crown of Great Britain’ (The Instructions, Secret, 30 July 1768)

  8. Venus transited June 8 2004 Unfortunately, we couldn’t see it in Hawaiÿi!!!

  9. I hope you didn’t miss June 6 2012 !!!

  10. (1836-1891) King Kaläkaua He lived in both worlds

  11. King Kaläkaua’s interest in Astronomy Hosted English Astronomy Expedition “Transit of Venus” in 1874

  12. “It will afford me unfeigned satisfaction if my kingdom can add its quota toward the successful accomplishment of the most important astronomical observation of the present century and assist, however humbly, the enlightened nations of the earth in these costly enterprises...” King Kaläkaua’sAddress to Astronomers December 15, 1874
