BERKELEY, Calif., Sept. 22, 2006 -- Startling evidence that there is more than one kind of Type Ia supernova -- a class of exploding stars which until now has been regarded as essentially uniform in all important respects -- has been discovered by scientists affiliated with the SuperNova Legacy Survey (SNLS). They found that the Supernova SNLS-03D3bb is more than twice as bright as most Type Ia supernovae but has much less kinetic energy, and that it appears to be half again as massive as a typical Type Ia. The lead authors of the report, which appears in the Sept. 21 issue of Nature, include Andrew Howell, formerly of the...Read full articleRelated content from Photonics MediaARTICLESQuantum Dots Enhance Stability of Perovskites for Solar PowerA team from the University of Toronto is researching materials that could enhance the solar-harvesting potential of silicon by absorbing wavelengths of light that silicon does not absorb.

If the compensating axial motion is accomplished without the...Photonics HandbookCamera Resolution: Combining Detector and Optics Performance: Most image-quality discussions center on resolution, which is thought to uniquely determine system performance. Resolution, however, is a more complex concept.Camera resolution depends upon the optical blur diameter and the detector size.
