There are ___________________ officially recognized constellations.
This moon rises at noon, is high overhead at sunset and sets around midnight.
In 5,000 years, our "North Star" will be in the constellation
The astronomical zodiac contains _________ constellations.
The Earth's rotational plane is tilted _____________ degrees with respect to its orbital plane.
What types of electromagnetic radiation from space reach the surface of the Earth?
Star A has a temperature 1/2 that of star B, but star A is 5 times bigger (i.e. radius) than star B. Which statement below is correct? Recall Stefan-Boltzmann's Law:L=��2�4where the area of the star is represented by R2 where R is the radius of a star.
If new moon fell on March 2nd, what is the Moonʹs phase on March 9th?
Recall that light collecting power (related to image brightness) depends on the DIAMETER of the mirror or lens SQUARED. Telescope A has a mirror with a diameter of 2.00 m and is used to view an astronomical object. When using Telescope B to view the same object, it appears 25 times brighter. That would mean the diameter of Telescope 2's mirror is
Only at the equator are all the stars visible over the course of the year.
A star's radiates most intensely at 0.07 cm. Knowing its peak wavelength, determine its "surface" temperature, T.Recall Wien's Law states Lambdamax=0.29/T(where the wavelength is measured in centimeters and the temperature in Kelvin )
If the temperature of a radiating body were to double, the energy emitted by that body would
The place the Sun stops its northward motion along the ecliptic is the:
You note that a particular star is directly overhead. It will be directly overhead again in:
Star A's radiation peaks at a temperature of 3600K while Star B's radiation peaks at a SHORTER WAVELENGTH. This would mean that
The angular resolution is the ability to distinguish two or more different objects that are close together. The angular resolution is directly proportional to the wavelength and inversely proportional to the diameter:What would the resolution be using a 6.00 m diameter mirror and blue light (400 nanometers which is equivalent to 0.400 micrometers)?
The top spectrum is from a star that is known as an A-type star. The two bottom spectra are from atomic ("neutral") calcium (Ca I) and atomic ("neutral") hydrogen (H I), respectively.Based on a comparison of the A-type's spectrum to the spectra of neutral calcium and neutral hydrogen, what can you conclude about the composition of this star?
If Pisces is now rising at sunset, which constellation will rise at sunset next month?
Analyzing a star's spectral lines can tell us about all of these EXCEPT
A telescope that is measuring phenomena in IR range would ideally be located at the top of a mountain to reduce atmospheric distortion.
