  • Hubble Discovers New Class of Gravitational Lens for Probing the Structure of the Cosmos
    of supermassive black holes, and even determining if the universe will expand forever or eventually collapse. The two gravitational lenses were discovered in about 100 fields of sky imaged by Hubble's Wide Field Planetary Camera 2 (WFPC 2). Because the combined area surveyed is about that of a full
  • Biggest 'Zoom Lens' in Space Takes Hubble Deeper into the Universe
    The Advanced Camera for Surveys aboard NASA's Hubble Space Telescope has used a natural "zoom lens" in space to boost its view of the distant universe. Besides offering an unprecedented and dramatic new view of the cosmos, the results promise to shed light on galaxy evolution and dark matter
  • Biggest 'Zoom Lens' in Space Takes Hubble Deeper into the Universe
    A selection of cropped images from a NASA Hubble Space Telescope Advanced Camera for Surveys view of one of the most massive galaxy clusters known, called Abell 1689. These close-ups show "lensed" images of background galaxies that have been brightened and smeared by the gravitational bending

  • Damping Grease - An Economical Approach to Motion & Noise Control (.pdf)
    is to control motion and noise in mechanical and electromechanical devices. Think of a zoom lens on a 35mm camera. The "velvet feel," virtually silent operation, and the fact that the lens doesn't coast are all the work of a damping grease on the focusing threads. ./cd1913d4-8610-4816-9efa-008c609c2f81
  • SRF, HRF, SSR. What Do These Acronyms Really Mean? (.pdf)
    . INTRODUCTION. The following statements come from the ITC Level 2 course. -. A higher number of pixels means you will find smaller problems at greater distances. -. Using a telescope with a lower resolution camera improves the resolution, but also diminishes the. field of view. -. At a given distance
  • The Importance of Spatial Resolution in IR Thermography Temperature Measurement - Three Brief Case Studies
    leveraging. The latter means it is more difficult to get a good, stable. image with a telescope attached as small motion of the IR camera is magnified by the power of the telescope. This is why digital camera companies have patented image stabilizing telescopes for their cameras. The. thermographer
