RECAP Double Rainbow, What Does It Mean? Our newest member Howard Williams witnessed a gorgeous double rainbow out on a drive on the 7th of April, 2016. We are fortunate Harold shared his images with the club!

RECAP 2016 Vatican Observatory Faith and Astronomy Workshop by Rosemarie Spedaliere Image credit: John Endreson Last September I was accepted to attend the 2016 Vatican Observatory Faith and Astronomy Workshop, an opportunity of a lifetime! A chance to mingle my love of astronomy and my religious beliefs. On January 11th I arrived in Tuscon to a beautiful crystal blue sky. My room was at the Redemptorist's Retreat Center, and after checking in I walked the grounds to familiarize myself with the lay of the land. There was a labryinth, some meditation rooms, the chapel, a classroom, and the nightly observing area. Our first trip to the University of Arizona Lunar Planetary Imaging Lab included their amazing meteorite collection photos from various space missions. After mass at the Retreat House, two of the Vatican staff priests approached me asking for my help with a 10" LX200! I was in Heaven! I set it up and ran into a few kinks with some of the 'scope's settings. Turns out I had to call our vice president John Endreson back for help puzzling it out. My claim to fame: I taught Vatican astronomers how to use a telescope! The next morning, I saw Omega Centauri through my binoculars... WOW! After class and My first evening I was honored to be asked to read at mass with the Bishop. After dinner, there lunch, we visited the Mirror Lab in Tucson to was an informal meet and greet before heading learn how mirrors are made. Our tour included a visit to the oven. Outside the building was a out to look at the stars. I brought my 15x70 'Moon Trees', grown from a seed brought back binoculars, and the retreat house's 6" by Apollo 14. How did I never hear about these Dobsonian and their 8" Schmidt Cassegrain trees? were at our disposal. I secretly vowed if I ever went out again, I'd ship out my telescope. With After mass and dinner, we hurried outside for my trusty green laser in hand, I immediately more observing! We were joined by the local went into star party mode. Our days were astronomy club and a yoga group staying at the rounded with stargazing, early in the morning center. Topping off my night, I was lucky enough and late at night. Page 3
RECAP Image credit: John Endreson to use the LX200 again! In just a few hours, we'd be up again at 5 in the morning. What was really fun was spotting Comet Catalina in the Catalina Valley of the Catalina Mountains, nice! Later we went on a field trip to Kitt Peak. I got all choked up heading up the mountain, unable to believe I was really there. Our first stop was the 2598 feet above sea level to see the Steward Observatory's 2.3 meter Bok telescope. One of the Vatican priests was gracious enough to give us a behind the scenes tour, showing me the control room after mentioning my friend, Dr. Hal, was Bok's nephew. Next stop was the Mayall 4 metere reflector. Our next stop was higher up, at 6960 feet, at the Mayall 4m reflector. They ran the telescope for us, letting us look at the mirror! That night mass was held under the desert stars. Again they asked me to read, and it was a dream come true. The next morning we woke for a final stargazing session, but the clouds had other plans, reminding us it was time to go home. OBSERVING CALENDAR May 5th, 6th The Eta Aquarids coincide with the new moon, making excellent observing at midnight as they fall from the constellation Aquarius. Northern hemisphere viewers can expect about 30 meteors an hour. May 9th Planet Mercury will transit the sun starting at 7:12 a.m.until 2:52 p.m. EDT. We are fortunate living on the east coast, bearing witness to the entire event. The next Mercury transit happens on November 11th, 2019. May 14th International Astronomy Day is an annual event to educate the public about astronomy. ASTRA will be celebrating Astronomy Day at Jakes Branch from 2 p.m. 'til 11 p.m.. May 21st May's full moon is the third of four full moons in 2016, making it a blue moon. Its nicknames are the Full Flower Moon, Full Corn Planting Moon, and the Milk Moon. May 22nd Mars will be at opposition this night, shining at 2 magnitude in Scorpius. Being only.51 AU from Earth, its disk will measure 18.4 arcseconds in diameter. Page 4
SPACE PLACE Hubble Shatters Cosmic Record For Most Distant Galaxy By Ethan Siegel The farther away you look in the distant universe, the harder it is to see what's out there. This isn't simply because more distant objects appear fainter, although that's true. It isn't because the universe is expanding, and so the light has farther to go before it reaches you, although that's true, too. The reality is that if you built the largest optical telescope you could imagine even one that was the size of an entire planet you still wouldn't see the new cosmic record holder that Hubble just discovered: galaxy GN z11, whose light traveled for 13.4 billion years, or 97% the age of the universe, before finally reaching our eyes. discovered galaxy, GN z11, its whopping redshift of 11.1 pushed that line all the way out to 1471 nanometers, more than double the limit of visible light! Hubble itself did the follow up spectroscopic observations to confirm the existence of this galaxy, but it also got lucky: the only reason this light was visible is because the region of space between this galaxy and our eyes is mostly ionized, which isn't true of most locations in the universe at this early time! A redshift of 11.1 corresponds to just 400 million years after the Big Bang, and the hot radiation from young stars doesn't ionize the majority of the universe until There were two special coincidences that had to 550 million years have passed. In most line up for Hubble to find this: one was a directions, this galaxy would be invisible, as the remarkable technical achievement, while the neutral gas would block this light, the same way other was pure luck. By extending Hubble's the light from the center of our galaxy is blocked vision away from the ultraviolet and optical and by the dust lanes in the galactic plane. To see into the infrared, past 800 nanometers all the way farther back, to the universe's first true galaxies, out to 1.6 microns, Hubble became sensitive to it will take the James Webb Space Telescope. light that was severely stretched and redshifted Webb's infrared eyes are much less sensitive to by the expansion of the universe. The most the light extinction caused by neutral gas than energetic light that hot, young, newly forming instruments like Hubble. Webb may reach back stars produce is the Lyman α line, which is to a redshift of 15 or even 20 or more, and produced at an ultraviolet wavelength of just discover the true answer to one of the universe's 121.567 nanometers. But at high redshifts, that greatest mysteries: when the first galaxies came line passed not just into the visible but all the way into existence! through to the infrared, and for the newly Image credit: NASA, ESA, P.
