Estimate the minimum telescope diameter that the satellite must carry. (Hint: Use The small-angle formula angular diameter (arc seconds) 2.06 105 = linear diameter distance to convert linear size to angular size.)arrow_forwardWhen astronomers discuss the apertures of their telescopes, they say bigger is better. Explain why. a) A wider aperture can observe a significantly larger portion of the sky. b) A wider aperture makes a telescope easier to aim. c) A wider aperture allows a telescope to collect more light, so it can produce images with higher resolution. d) A wider aperture allows a telescope to collect more light, so it can detect fainter light sources.arrow_forwardList the largest-aperture single telescope currently in use in each of the following bands of the electromagnetic spectrum: radio, X-ray, gamma ray.arrow_forward
