Explore new galaxies in presentation


The Universe Tonight program at 6 p.m. Saturday, March 2, at the Mauna Kea Visitor Information Station will feature Rene Pierre Martin of the Hoku Ke‘a Observatory. Everyone is invited to the free monthly program on the Magnificent Barred Spiral Galaxies.

Did you know about a stellar object in spiral galaxies called barred spirals?

“Come join us at the Visitor Information Station, as Dr. Rene Pierre Martin discusses the importance of barred spirals objects in spiral galaxies,” said spokeswoman Janet Nathani. “In this presentation, he will review some of the early history of observations of spiral galaxies, including some of the first descriptions of galaxies with bars. Then, he will review how bars can be formed, how they evolve and how they might considerably affect the evolution of their host galaxies.

“See that some galaxies have more than one bar and that our own galaxy, the Milky Way, is in fact a barred spiral. Finally, he will briefly describe an ambitious project to be undertaken with an innovative instrument at CFHT on Mauna Kea next year, aiming in better understanding of the significance of bars in galaxies. But, maybe more importantly, it will show that barred spiral galaxies are among the most grandiose and beautiful objects in the universe.”

Martin is an assistant professor of physics and astronomy and the director of the UHH Hoku Ke‘a Observatory on Mauna Kea.
