Rowan Hosts Supernovae SpeakerMarch 08, 2006
Dr. Kyle Dawson will present ?Using Supernovae and the Hubble Space Telescope to Explore the History and Fate of the Universe? in Rowan Hall at Rowan University on Thursday, March 23, from 7 to 8 p.m.
Dawson is a postdoctoral researcher at the Lawrence Berkeley National Laboratory operated by the University of California. His lecture will examine using supernovae to measure distances in the universe. He also will discuss improvements in space measuring technology, such as the Hubble Space Telescope. According to NASA?s Goddard Space Flight Center Web site, a supernova is the explosion caused when a massive star, at least eight times the Sun's mass, dies and collapses.
According to Dawson, ??an unseen ?dark energy? actually accelerates the universe's expansion. It now appears that the universe will not come to an end in a big crunch, but instead will expand forever. However, the nature of this dark energy is still poorly understood and requires further investigation.?
The event, part of the annual Spring Equinox Lecture Series, is co-sponsored by the Rowan University Physics Department, Edelman Planetarium and the College of Engineering. The event is appropriate for a general audience is and free and open to the public.
