A remote-sensing payload operates in the
infrared part of the spectrum (lambda = 1
micrometer). If it has an aperture diameter
of 1 m, what would its resolution be (in
meters) while operating in a
geosynchronous orbit (35,786 km)?
What formula would I use to find this?
Provide two words as an answer.
What two entities comprise the visible spectrum?
How does the resolving power of the Mount
Palomar 5-m telescope compare with that of the
2.4-m Hubble Space Telescope?
AMount Palomar
dHubble Space Telescope
Why does HST generally still outperform the
ground-based 5-m telescope?
The resolving power of the Mount Palomar 5-m telescope has a higher value than that of HST, and telescopes with higher values for
resolving power can not distinguish objects as well as telescopes with lower values for resolving power.
Earth's atmosphere affects visibility for the Mount Palomar 5-m telescope and limits resolving power to about 0.5 seconds of arc. HST is not
affected by distortion due to the atmosphere.
The resolving power of the Mount Palomar 5-m telescope has a lower value than that of HST, and telescopes with lower values for resolving
power can not distinguish objects as well as telescopes with higher values for resolving power.
HST is in orbit around the Earth, and so it is closer to the stars than the Mount Palomar 5-m telescope. By being…

- The edge of the Sun doesn’t have to be absolutely sharp in order to look that way to us. It just has to go from being transparent to being completely opaque in a distance that is smaller than your eye can resolve. Remember from Astronomical Instruments that the ability to resolve detail depends on the size of the telescope’s aperture. The pupil of your eye is very small relative to the size of a telescope and therefore is very limited in the amount of detail you can see. In fact, your eye cannot see details that are smaller than 1/30 of the diameter of the Sun (about 1 arcminute). Nearly all the light from the Sun emerges from a layer that is only about 400 km thick. What fraction is this of the diameter of the Sun? How does this compare with the ability of the human eye to resolve detail? Suppose we could see light emerging directly from a layer that was 300,000 km thick. Would the Sun appear to have a sharp edge?arrow_forwardSuppose you are looking for sites for a visible-light observatory, an infrared observatory, and a radio observatory.

- Many decades ago, the astronomers on the staff of Mount Wilson and Palomar Observatories each received about 60 nights per year for their observing programs.
