Professor Filippenko shares his Blue Angels flight experience with the public to promote the importance of math and science curricula as core drivers of technology and medical innovation. San Francisco, CA (PRWEB) October 05, 2012 University of California, Berkeley astronomy Professor Alex Filippenko was chosen as one of the prominent Bay Area personalities to soar over the San Francisco Bay Area in a pre-performance flight with the Blue Angels on October 3, 2012. Professor Filippenko was...

Survey Hints At Origin Of Type Ia Supernovae
2011-10-08 05:13:10

The largest survey to date of distant exploding stars is giving astronomers new clues to what´s behind the Type Ia supernovae they use to measure distances across the cosmos. These stellar explosions helped astronomers conclude more than a decade ago that dark energy is accelerating the expansion of the universe, and today (Tuesday, Oct. 4) earned the discoverers — including UC Berkeley physicist Saul Perlmutter — the 2011 Nobel Prize in Physics. But what caused them was a...

In the past decade, robotic telescopes have turned astronomers' attention to scads of strange exploding stars, one-offs that may or may not point to new and unusual physics. But supernova (SN) 2005E, discovered five years ago by the University of California, Berkeley's Katzman Automatic Imaging Telescope (KAIT), is one of eight known "calcium-rich supernovae" that seem to stand out as horses of a different color. "With the sheer numbers of supernovae we're detecting, we're discovering weird...

The Hubble Space Telescope will devote an unprecedented amount of time over the next few years to documenting galaxy evolution in the early universe and to studying whether distant supernovae can be extremely reliable measures of distance across vast regions of the cosmos. In this ambitious new project, Hubble will image more than 250,000 distant galaxies in five directions, providing the first comprehensive view of the structure and assembly of galaxies over the first third of cosmic time....

But not the last, now that astronomers know where to look An extraordinarily bright, extraordinarily long-lasting supernova named SN 2007bi, snagged in a search by a robotic telescope, turns out to be the first example of the kind of stars that first populated the Universe. The superbright supernova occurred in a nearby dwarf galaxy, a kind of galaxy that's common but has been little studied until now, and the unusual supernova could be the first of many such events soon to be discovered. SN...

There is no age restriction on the chance to make a significant contribution to our understanding of the universe. Caroline Moore, a 14-year-old from Warwick, N.Y., has made such a mark on astronomy with the discovery of Supernova 2008ha. Not only is she the youngest person to discover a supernova, but this particular supernova has been identified as a different type of stellar explosion."It's really a strange supernova," said Moore. "A supernova is a huge explosion deep in the core of a...

Type Ic supernovae, or hypernovae, may be source of powerful bursts Berkeley -- Observations by two of the world's largest telescopes provide strong evidence that a peculiar type of exploding star may be the origin of elusive gamma-ray bursts that have puzzled scientists for more than 30 years. A team of astronomers from Italy, Japan, Germany and the United States, including the University of California, Berkeley, conclude from observations with the Keck and Subaru telescopes in Hawaii that...
