What angular resolution would you need to see the Sun and Earth as distinct points of light? If you were looking at it from 13 light years away?
very optical device has an angular resolution, the smallest angle over which it allows us to tell if two dots -- or two stars -- are distinct. If two stars have an angular separation less than the angular resolution, they appear as as a single object. This limited angular resolution can arise for a number of reasons: quality of the optics, blurring of the atmosphere and quantum mechanics. For example, from the ground on Earth, due to the blurring of...
37. Jupiter at its present location, were a star? What would Earth be like ? Assume this hypothetical Jupiter with 75 × MJ would be a red dwarf with the same density as the Sun but a surface temperature of only 2500 K. What would be its total luminosity, compared to that of the Sun? (Hint: recall that to be a star, Jupiter would have to be 75 times more mass than it has today.)
Diffraction imposes a limit on the achievable resolution of an instrument. What is the smallest angular separation that two stars could have when viewed with a telescope with a diameter of 0.5 m. (A wavelength of 600 nm would be suitable as an estimation for visible light)
What is the angular diameter of a star like the sun located 6 ly from Earth? (I have the formula I need to determine this answer, but I am looking for some guidance on how to enter this equation in my calculator to arrive at the final answer. Can anyone help?)
The Hubble Space Telescope has a mirror diameter of 2.4 m. Suppose the telescope is used to photograph stars near the center of our galaxy, 30,000 light years away, using red light with a wavelength of 720 nm . A) What's the distance (in km) between two stars that are marginally resolved? The resolution of a reflecting telescope is calculated exactly the same as for a refracting telescope. B) For comparison, what is this distance as a multiple of the...
1.) At what distance would a satellite orbiting the Earth be geosynchronous (orbiting the Earth once every 24 hours)? It would be geosynchronous at _________ × 104 m from the center of the Earth or __________× 104 m from the Earth's surface. 2.) Hydrogen also produces spectral lines at radio wavelengths, notably at 21.1 cm. If a galaxy is moving away from us at 9% of the speed of light, at what wavelength will we detect this line? Convert this...
Suppose you have a near-point distance of 26 cm. The angular resolution of the eye is determined by diffraction (see the Rayleigh criterion) and is approximately 1 arcmin. (Note that 1°=60 arcmin.) What is the smallest object your bare eye can resolve?

f) in vacuum, light travels at about 186,282 miles per second. One mile is about 161 kilometers (km). Astronomers prefer to use units of distance that are reasonable in describing how far objects are from Earth. For example, for distances in the solar system we use the astronomical unit (AU), which is equal to the average distance of Earth from the Sun; 1 AU is about 150 million km. For distances to stars and galaxies, astronomers use the light-year (1...
