Washington DC: In the most remote locations on the planet, people are working to uncover mysteries throughout the universe… and most are not astronomers. Big Astronomy in Chile through Dome+ (Big-ACT) explores a new model to deliver a unique learning experience for planetarium visitors around the world. By integrating virtual interactions with those living and working at the observatories, curricular resources, and the planetarium show, Big-ACT will advance the public’s awareness of the National Science Foundation (NSF) funded observatories in Chile, and the diverse people and careers it takes to make big science possible today. With support from NSF-Advancing Informal STEM Learning program, Associated Universities Inc. (AUI), partners with Michigan State University, the California Academy of Sciences, Astronomical Society of the Pacific, Association of Universities for Research in Astronomy, National Optical Astronomy Observatory, Gemini Observatory, and the Atacama Large Millimeter/submillimeter Array to complete the new $2 million project.

Big-ACT is set in Chile where the dry, dark, sky, and remoteness creates an ideal site to observe the universe. By the year 2022 it is expected that nearly 70% of the world’s ground-based observing infrastructure will be located there, and the US and other countries are investing billions of dollars in astronomy in Chile. Big-ACT introduces audiences to the wide variety of personnel involved in advancing astronomical discovery. “When people think of astronomy they often imagine astronomers peering through telescopes,” says AUI President, Adam Cohen, “they are unaware of the STEM village it takes to make exploration of the cosmos possible.” Big observatories today employ electrical and mechanical engineers, technicians, data analysts, machinists, heavy equipment operators, maintenance personnel, artists, cooks, etc. Each of these individuals play an important role in making astronomical discoveries possible.

Beyond the fascinating places and people involved in astronomical research, the show includes the fruits of the research itself. “We are excited by the opportunity this project presents to both formal and informal STEM educators,” explains Tim Spuck, AUI Director of Education and Public Engagement and Principal Investigator (PI) for Big-ACT, “Astronomy excites learners of all ages. We can use the power of astronomy to help individuals understand that they can be part of amazing science and discoveries without necessarily becoming a PhD astronomer. We want every person attending the planetarium show to be able to connect the people they see to someone they know or someone they themselves can one day become.” The Dome+ model will also support engagement beyond the planetarium show through a dynamic web portal. The portal will include learning activities, interviews with observatory personnel, and a schedule of live virtual sessions with those working at the observatories. The curricular resources and planetarium show will be made available in both English and Spanish for dissemination here in the US and Latin America. Big-Act will be coming soon to a planetarium near you as well as the World Wide Web in the spring of 2020.

VIDEO: Multi-wavelength Observations Reveal Impact of Black Hole on M87 Galaxy

In 2019, a worldwide collaboration of scientists used a global collection of radio telescopes called the Event Horizon Telescope (EHT) to make the first-ever image of a black hole — the supermassive black hole at the core of the galaxy M87, some 55 million light-years from Earth.

ACEAP Alumna Selected as Astronaut for SpaceX

Sian Procter, a participant in the Astronomy in Chile Educator Ambassadors Program (ACEAP) in 2016, has been selected as an astronaut by SpaceX. The Inspiration4 mission, scheduled to launch sometime after 15 September 2021, will orbit Earth for three days and conduct a variety of experiments.

New Images Reveal Magnetic Structures Near Supermassive Black Hole

The Event Horizon Telescope (EHT) — the worldwide collaboration that produced the first image of a black hole in 2019 — has produced a new image showing details of the magnetic fields in the region closest to the supermassive black hole at the core of the galaxy M87. The new work is providing astronomers with important clues about how powerful jets of material can be produced in that region.

After Long Shutdown, Giant Radio Telescope Array Set to Resume Observations

The Atacama Large Millimeter/submillimeter Array (ALMA), a set of 66 radio astronomy dishes perched high in the Chilean Andes, was hit hard by the pandemic. It shut down on 22 March 2020 and has remained silent ever since—far longer than most scientific facilities....
