My Two Favorite Radio Programs
Jul 17, 2003 - If you're interested in science and discovery in general, I'd like to suggest two weekly, hour-long radio shows that you should tune into - through the Internet.

  • Quirks and Quarks - Every Canadian reader will know exactly what I'm talking about. This is a weekly radio show on the Canadian Broadcasting Channel hosted by Bob McDonald. They have archives available online going back almost 10 years.
  • NPR Science Friday - Every Friday, NPR's Talk of the Nation is taken over by Ira Flatow to discuss the latest happening in science. It's a great show.

New Camera Catches a Near Earth Object Already

Jul 17, 2003 - Even though it's still in its initial commissioning trials, NASA's quasar Equatorial Survey (or Quest) camera system attached to the 1.2 metre Oschin telescope on Palomar Mountain has already bagged an asteroid. The 250-metre near-Earth object (NEO) 2003 NL7 was discovered on the evening of July 8 by the Quest system, and then later confirmed by several other observatories. Once Quest is fully operational, it should be 3 to 4 times better than the older equipment it replaced.

NASA Creates an Independent Safety Centre

Jul 17, 2003 - NASA announced the creation of an independent Engineering and Safety Center (NESC) at the agency's Langley Research Center. The 250-person division will provide independent assessment and safety review for various NASA projects and missions. The office was a response to the Columbia disaster, ideally to prevent the kind of safety problems that were uncovered by the investigation team. The team leader has yet to be announced.

Supernovae Produce Dust More Efficiently Than Previously Thought

Jul 16, 2003 - A new article published in the journal nature helps settle a long-time mystery about some of the earliest solid particles in the Universe. By measuring supernova remnant Cassiopeia A with the very precise SCUBA telescope, Astronomers were able to detect enormous quantities of cosmic dust below -257 degrees Kelvin. Hot dust had been found in the past, but the colder dust was mostly invisible - until now. It appears that supernovae are extremely efficient at producing the dust that later forms planets, rocks, and people.

Image of a Cosmic Mirage

Jul 16, 2003 - Astronomers from the European Southern Observatory have found a very rare "Einstein ring" gravitational lens, where the light from a distant quasar is warped and magnified by the gravity of a closer galaxy. The two objects are so closely aligned that the image of the quasar forms a ring around the Galaxy from our vantage point here on Earth. With careful measurements, the team was able to determine that the quasar is 6.3 billion light-years away, and the Galaxy is only 3.5 billion light-years away, making it the closest gravitational lens ever discovered.
