(a)

To determine

The diameter (in light-years) of the smallest relevant detail that can be discerned in the image, if the angular resolution of the Hubble Space Telescope (HST) image is 0.1 arcsec, and the HST has been used to observe the galaxy M100, present some 70 million light-years from Earth.

(b)

To determine

The position (in kilometers) of a U.S dime (diameter 1.8 cm) with an angular size of 0.1 arcsec, if the Hubble Space Telescope (HST) has been used to observe the galaxy M100, present some 70 million light-years from Earth.

When two objects are far away, an observer moving will see a shift of the closest object relative to the farthest object. This shift is known as a.triangulation. b.parallax. c.a baseline. d.a degree. e.an arc second. What advantages do large telescopes have over smaller ones? a.larger collecting areas b.both superior angular resolution and less aberration c.superior angular resolution d.less aberration e.better exposure times What is the name given to a day which uses the stars as a reference? a.solar day b.diurnal day c.sidereal day d.orbital day e.none of the mentioned choices
spy satellite orbiting 410 km above Earth is supposedly capable of counting individual people in a crowd in visual-wavelength images. Assume that the satellite's cameras operate at a wavelength of 550 nm. Assume an average person has a size of 0.6 m as seen from above. 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.)
the SETI project's Allen Telescope Array will have 350 radio dishes, each with an individual diameter of 6 m, spread out over a circle whose diameter is 1 km. What would this array's spatial resolution be when it operates at 6,000 MHz?
