A window to the universe is open in Central Oregon

- By Erin E. Williams

Our gazes first met at a party, from across a crowded galaxy. I gaped at an object of impossible beauty seemingly bedecked in diamonds. It stared back at me, and the 34,000-light-year distance between us disappeare­d. Star-struck, I couldn’t tear my eyes away.

The object of my attraction was Messier 3, one of the night sky’s biggest and brightest globular star clusters. And the party was Astronomy Day, held on May 11 and Oct. 5 this year. I was celebratin­g at the Oregon Observator­y at Sunriver, which houses about 30 telescopes in the country’s largest facility for public viewing.

The nonprofit Oregon Observator­y is dedicated to providing public access to the heavens. Unlike most research observator­ies where visitors admire telescopes from afar, it encourages aspiring astronomer­s to get an eyeful through its scopes, typically 12 to 15 on a given night. Celestial bodies are the stars of the show. And they’re easy to spot, thanks to clear air and the darkness; Sunriver, the surroundin­g resort town, has a stringent lighting ordinance that protects the night sky from light pollution.

“We want people to look though the eyepieces,” said observator­y manager Robert Grossfeld, who has worked at the site since it opened in 1990. “Public access to such an array of telescopes is unusual. We have a diverse collection, and because different telescopes do different things well, people can view a wide range of objects in the sky.”

Planetary viewing is often a highlight, since visitors can recognize details such as Jupiter’s moons and Saturn’s rings. But spring and fall are prime times for globular clusters (dense collection­s of ancient stars), especially on nights when bright moonlight might drown out the planets.

The observator­y also offers daily solar viewing through two special telescopes that allow visitors to safely watch hydrogen storms and sun spots.

For the biannual star party, I had driven a halfhour from downtown Bend. Frogs croaked in the fading twilight, which painted the surroundin­g Central Oregon high desert pastel. I followed a trail of red lights (the color helped our eyes remain adjusted to the darkness) to the two-story observator­y dome, through a starport with a roll-off roof and finally to a star deck outside; in these areas, 14 telescopes pointed at different astronomic­al marvels.

A couple dozen adults and children were already waiting for their chance to peek into the cosmos. A few fervent amateur astronomer­s had set up their own telescopes, and newbies shared their galaxy-sized enthusiasm.

“This is awesome!” a man said as he gestured at the scattered scopes. “Lookatthat,thereare even more telescopes over there! This is going to be awesome!”

I was looking at the Great Cluster in Hercules, a globular star cluster with about 300,000 stars. As my sight adjusted, shapes emerged: subtle whorls that resembled a pinwheel twirling through countless pinpricks of light. Paul Poncy, the observator­y’s program facility lead, oriented a 12.5-inch telescope toward the waxing crescent moon. Its craters were so textured, their nubby indentatio­ns appeared within arm’s reach.

While we waited for the sky to darken, Poncy gave a talk on Mars in an outdoor amphitheat­er. In the summer, the observator­y rotates several presentati­ons that focus on planets, the solar system and constellat­ions.

Up to 300 people might visitonaju­lyoraugust night, but on this May evening, only 100 visitors craned their necks to the sky and tilted their ears to a dozen staffers and volunteers who were describing the sights. Fall and winter nights are similarly uncrowded.

“We call the dim stuff ‘faint fuzzies,’ ” said a volunteer as he took a break from answering a little girl’s astute questions about triple star systems. “The longer you look, the more you see depth, patterns, colors and shape.”

I rubberneck­ed through telescope after telescope. In one, I peeked at Arcturus, a red giant star. In another, the Sombrero Galaxy, whose center probably contains a gigantic black hole. In a third, a flash of silver streaked across my field of vision: a shooting star.

Finally, I blinked into an eyepiece at glittering Messier 3.

“Its nearly half a million stars are among the oldest in the universe, about 8 to 11 billion years old,” explained a volunteer. “Given that the universe is about 14 billion years old, they’re some pretty old stars.”

Over two hours, I had journeyed across the universe, but the observator­y was closing and I needed to return to Earth.
