Alumnos y profesores de La Serena están a punto de partir en un Viaje al Universo único. Muy pronto, el programa anual del Observatorio Gemini, que potencia el aprender pensando y haciendo, despegará con más fuerza que nunca. Este programa lleva a profesionales de la ciencia y tecnología de Gemini y de otros observatorios a las salas de clases para compartir su trabajo con la próxima generación de exploradores. Además, se incluyen programas de Planetario Móvil que acercarán el Cosmos hasta la Tierra con un universo repleto de demostraciones entretenidas e innovadoras.

Una novedad para este año es la visita del grupo de reconocidos científicos y comediantes españoles Big Van “Científicos sobre Ruedas.” Los Big Van son “extrovertidos científicos”, señala la Sub Directora de Gemini, Nancy Levenson. En realidad, ellos son astrofísicos (y un biólogo) quienes luego de ganar el concurso de Monólogos Científicos de Europa, se abocaron de lleno a compartir su conocimiento y su entusiasmo por el mundo. Ellos atraen de manera inesperadamente divertida, recurso que denominan “intervenciones”. Estos consisten en rutinas de stand up comedy educacionales a través de las cuales explican conceptos científicos usando siempre la justa cuota de humor. Puedes averiguar más sobre ellos en este sitio http://www.thebigvantheory.com

El programa de Viaje al Universo este año trabajará con profesores, alumnos y apoderados de los colegios: Trinity School, San Nicolás y St. Mary’s School del sector El Milagro; Colegio San Joaquín, además de los establecimientos Carlos Condell de la Haza y Martín de Porres en Las Compañías. Cada uno de estos colegios recibirá la visita de astrónomos y científicos en general, quienes llevarán presentaciones especialmente preparadas para el grupo y edad de los cursos, además del Planetario Móvil, módulos para la familia y una presentación masiva de The Big Van.

Aunque Viaje al Universo se centra prioritariamente en las escuelas, The Big Van hará presentaciones públicas para un número limitado de interesados. Una de ella se hará en Lighthouse CoffeeShop de La Serena, donde presentan su “Café conCiencia,” programado para el martes 20 de octubre a partir de las 18:30 horas. (Obtenga sus tickets directamente en Matta 570, La Serena). La otra presentación se realizará en el colegio St. Mary’s School – El Milagro el día jueves 22 de octubre a partir de las 18:30. El espacio aunque gratuito, también reducido, por lo que invitamos a reservar directamente llamando al colegio en el número 51- 2293143 lo antes posible.

A Gemini Intern’s Night on the Summit!

 

Aloha! My name is Alyssa Grace and I’m a University of Hawai‘i at Hilo student interning at Gemini Observatory in the Public Information and Outreach department. In order to share more about what being an astronomer is like, I decided to live the days of a certain type of astronomer, a Science Operations Specialist (SOS), for a weekend at the Gemini North telescope.

Through the criss-crossing beams of Gemini's vents I could see Haleakala, Canada-France-Hawaii Telescope, both the Keck Telescopes, and Subaru Telescope.

Through the criss-crossing beams of Gemini’s vents I could see Haleakala, Canada-France-Hawaii Telescope, both the Keck, and Subaru telescopes.

Once the shutter (what the telescope points out of) and the primary mirror are open, we head back down to the control room where the science begins.

Once the shutter (what the telescope “looks” through) and the primary mirror are open, we head back down to the control room where the science begins.

Imagine sitting in a cold room with three other people and 29 monitors for 10 hours every night, all weekend long. Well that’s exactly what I did and it was awesome. Operating the eight-meter Gemini telescope is done via computers and when we were not immersed in our screens, numbers, and excitement, we were talking and laughing about everything from genetic expression, globalization of nations and cultures, 1980’s rappers, and German idioms (“Have you tomatoes on your eyes” is the German equivalent of the expression “Are you blind?/ that outcome was entirely obvious”). There was also much food and hot cocoa involved.

“Observing” is most exciting to me when we are taking direct images of galaxies, supernovae, or comets (etc.) in the infrared. For example, at one point the observer took images of a comet at very short intervals in order to trace its path and in each picture we could see its movement against a background of streaking stars. Spectra are cool too, but not as instantaneously gratifying due to their needing further data analysis to really determine what exactly you are looking at (e.g. Does this galaxy have HII or H-alpha forming regions?) But by far, the best image I saw was from my SOS’s collection of awesome telescope pictures:

It’s a bright young star with its protoplanetary disk, saturating the charge-coupled device (CCD) in just the right way.

During especially long exposures (data-collection periods in which the telescope’s instrument’s shutter remains open to receive more light), the other intern and I would bundle up in thick layers of jackets and scarfs and venture outside the observatory with a pair of infrared goggles. With those goggles we could see five times as many stars; sharp, green and beautiful. We could see Keck 2’s laser aiding its exploration of the night sky. Without the goggles, we admired the long dusty plane of our Milky Way.    

Some days I couldn’t sleep. Being nocturnal is hard. So I learned new things about Hale Pohaku as well: the pool table is slanted, always check the expiration dates on yogurt, I’m terrible at ping pong.

Mild altitude sickness near the summit is common, but Gemini workers are accustomed to the elevation. I’ve listened to the experiences of other interns and I’ve heard horror stories (e.g. tour groups puking in the dome). Gemini is a great employer in terms of giving days off in compensation for time on the mountain. I was at the summit only three nights. So my transition back to a day schedule and lower altitude was not too bad. But others, after being on the mountain for five days, need at least one full day to readjust. On my second night of observing, my heart rate spiked after eating instant ramen. My SOS administered oxygen to me via a CHAD unit and cannula (nose tubes and mini O2 tank). I kept the nose tube as a souvenir.

Knowing exactly how a specific science is done goes a long way toward being able to communicate its importance and function to general audiences, and I hope to one day teach Astronomy to grade schoolers here on the Big Island so that they might discover even more about our universe than we can currently imagine.

On September 16th, 2015, La Serena was hit by a 8.3 earthquake (reported by USGS) at 19:54 local time, with the epicenter about 150km from La Serena. Fortunately, the Gemini staff at the summit and in La Serena are all fine. A first check of the telescope and installations were initiated after the quake and nothing obvious was noted, but it was decided to cancel observations that night. After a thorough inspection of the telescope, it was found that the telescope sustained minor damages, and would be closed until further notice.

Our thoughts go out to the people that lost their lives and homes due to the quake and the following tsunami that strongly impacted the coastal areas.

Check back periodically for updates on the Gemini South telescope.

Sept 25

We are pleased to announce that good progress has been made in recovering the Gemini South telescope, and we will begin on-sky testing Saturday, September 26th. The on-sky tests will confirm whether all is ok, or whether some further adjustments are needed before we resume science observations.

Sept 23

We have good news from today’s work on Cerro Pachón. The elevation axis is now operational, which means that it was possible to tilt the telescope to the horizon and fully inspect the secondary mirror. The more complete visual inspection showed no problems, so the engineering team proceeded with the initialization and test sequence. They moved M2 in all directions and repeated the initialization several times, all with success.

GMOS, FLAMINGOS-2, and GSAOI are fully cleared for operation. GPI has been in the summit lab, and the active vibration control now works, reducing vibrations by a factor of 10.

Some key milestones that remain are to complete the alignment of the azimuth bearing, and to test full ranges of motion of the telescope and M2. Getting the encoders back online will be another big task before resuming observing, but regular procedures with all necessary equipment on-hand.

Sept 22

We made good progress today on the Gemini South telescope recovery, as we work through the many systems methodically.

Key work today was progress on aligning the azimuth bearing. This should be completed tomorrow. A basic inspection of the secondary mirror from the cherry picker (telescope at zenith) did not show any obvious problems. Following work tomorrow, we expect to be able to move in elevation and do a more complete investigation of the secondary. In parallel, instruments are being checked out, finding no problems so far. The primary mirror control system has also checked out fine.

Sept 21

The hydraulic bearing system is back on, and the telescope is again centered at the nominal azimuth position. The oil system is showing low pressure, which will be investigated further tomorrow. The motion of the platform reported earlier moved two azimuth encoder heads, and the elevation encoder head needs adjustment. Some other components related to the cable wraps need replacement; we have spares on site that have been and/or will be prepared for use.

All dome mechanisms have checked out fine.

Additional key tasks for tomorrow will be to recover the elevation axis and to inspect the secondary mirror.

Gemini Pairs with CFHT to Launch Pilot Program

This year, the Canada-France-Hawaii Telescope (CFHT) in a partnership with the Gemini Observatory and the Hawai‘i State Department of Education is launching a pilot program, tentatively titled the Maunakea Telescope and Technology project. Ultimately, the project will allow high school students on Oahu and Hawaii Island to obtain data with the CFHT telescope. Initially, students will use existing Gemini data to produce color images and begin investigations with the data as part of the Live from Gemini virtual field trip program. Earlier this month, teachers from local high schools and staff from Hawai‘i observatories discussed plans on what they hope to gain from the program and how the program will work.

“We want to develop within the community a sense of pride and ownership in the observatories and STEM [Science, Technology, Engineering, Math] programs,” said Doug Simons, Director of CFHT, “It’s a unique and powerful educational opportunity.”

Students in high school classes at Waiakea (Big Island) and Kapolei (Oahu) will pair with mentors from CFHT, Gemini, and the Institute for Astronomy in Manoa to develop astronomy projects that are their own. These projects could be used for science fair and capstone projects, as well as STEM degree designation requirements. Mentors and teachers will then help students draft proposals vying for telescope time at CFHT. The students will be treated like principal investigators (PI’s) on their research project and will collect and analyze the data.

Participating teachers said the project would help kids get exposure to the telescopes and tech fields. They want their students to have access to and awareness of the tools, resources, and careers available in Hawai‘i.

“We want kids that are passionate as opposed to kids that are ‘the best and the brightest,'” said Naidah Gamurot, science teacher at Kapolei High School, “We want to provide opportunities for kids at all levels.”

With the success of the program, Gemini and CFHT hope to make this an annual program that expands to more schools and observatories.
