Astronomy on Tap Seattle last month celebrated its first year of of bringing the latest astronomical research and good beer to interested space geeks. The party was a little bittersweet, as they also announced that the series will be leaving Bad Jimmy’s Brewing Company for the larger Hilliard’s Beer Taproom, another Ballard watering hole.
The move does not come entirely as a surprise. The early Astronomy on Tap events last spring were well attended, and they’ve grown in popularity to the point where nearly 140 people were sardined into Bad Jimmy’s for the monthly gatherings. Brett Morris, an astronomy graduate student at the University of Washington who is the emcee and one of the co-founders of Astronomy on Tap Seattle, hinted at a move in an interview we posted before the birthday event.
“It’s been a wild ride growing from our initially small size to something that we almost can’t handle,” said Morris. “We’re going to try our best to keep up with it as it grows through our second year.”
Kristin Garofali, another co-founder of AoT Seattle, thanked Bad Jimmy’s for their support over the first year, noting that they even let participants vote to name their imperial Scotch ale (The Big Sipper) and at the birthday party served up a delicious version of it that was aged for several months in rum barrels.
“To see how this has grown has been super amazing,” Garofali said. She added that they hope to keep doing smaller events at Bad Jimmy’s.
Breanna Binder gave an interesting talk at the March 23 birthday event, about a supernova impostor that turned out to be an x-ray binary system. An amateur astronomer spotted what looked like a supernova in 2010, but it kept churning out x-rays long after it faded visually. Binder said that’s not how it’s supposed to work.
“Supernova 2010da, not only is it not a true supernova, it may be the youngest possible x-ray binary,” Binder said, noting that it theoretically takes between four and five million years before an x-ray binary begins emissions. They’d seen none prior to 2010. “The 2010 eruption might have been the birth of a brand new x-ray binary, which is something that we had never witnessed before.”
The story was featured on the popular website IFLScience. Binder will give a talk about the supernova impostor at the UW Astronomy Colloquium at 4 p.m. Thursday, May 5 in room A102 of the Physics/Astronomy Building on the UW campus in Seattle.
One of the other more interesting mini-talks of the evening was made by Dave Fleming, who took a look at the possible Planet 9. Astronomers have recently speculated that there’s a ninth planet in our solar system, a so-called super-earth that is somewhere between Earth and Neptune in mass and about 700 astronomical units out. Fleming noted that a fair chunk of the exoplanets discovered so far are in that mass range.
“If there is one of these guys lurking in the solar system, if we could actually detect it with a telescope and send a probe to it, it would give us a huge insight into the planet-formation process,” Fleming said. “If this ninth planet does exist, maybe it’s some relic of the planet-formation process that got scattered out by Jupiter.”
Former planet 9, and more
Morris showed a large number of photos that New Horizons shot at Pluto. He had given a talk back in July, on the day of the mission’s fly-by, and shared the very first pictures it beamed back to Earth. Though it will continue transmitting data for quite some time, we already have a sizable collection of pics from the system. Among the most interesting discoveries from the new batch: a large canyon around the equator of Pluto’s moon Charon that may indicate an underground ocean.
Other talks at the birthday event covered supermassive black holes, fast gamma-ray bursts, how to find a Tatooine, and funky, planet-shaped megastructures.
The next Astronomy on Tap Seattle event is planned for April 27 at Hilliard’s. The program has not yet been published.
