... Waxing means to increase in size or grow larger. Waning means to decrease in size or grow smaller. The moon can be seen during the day during several of the moon's phases. The time and length of day that the moon can be seen varies with the phase of the moon. The Moon does rotate on its axis. Its ro ...

... Without a telescope, you can see about 2000 stars in the night sky. Some appear brighter than others. One way to measure a star’s brightness is by magnitude. The brightness of a star depends on its temperature, size, and distance from Earth. A hot star is usually brighter than a cool star. A large s ...

... So, if 10 inches equals 864,000 miles, one inch will represent 86,400 miles. And 0.0000115 inch will represent a single mile approximately. At this scale, how big is the earth? Well, the earth is 7,913 miles in diameter. 7,913 times 0.0000115 equals 0.091 inches approximately—in other words, not qu ...

A closed orbit returns to itself in our case (in general it doesn’t do this but we will not worry about that). ...

... d) Do you think you might be able to resolve its disk with the U of A telescope? Why or why not (show a calculation)? The U of A telescope has an aperture of 12 inches (0.33 m), and therefore an angular resolution (in V band, 550 nm) of θ = 1.22 ∗ (5.5 × 10−7 m/0.33m) = 2.0 × 10−6 radians, or 0.4”. ...

Extraterrestrial skies



In astronomy, the term extraterrestrial sky refers to a view of outer space from the surface of a world other than Earth.The sky of the Moon has been directly observed or photographed by astronauts, while those of Titan, Mars, and Venus have been observed indirectly by space probes designed to land on the surface and transmit images back to Earth.Characteristics of extraterrestrial skies appear to vary substantially due to a number of factors. An extraterrestrial atmosphere, if present, has a large bearing on visible characteristics. The atmosphere's density and chemical composition can contribute to differences in colour, opacity (including haze) and the presence of clouds. Astronomical objects may also be visible and can include natural satellites, rings, star systems and nebulas and other planetary system bodies.For skies that have not been directly or indirectly observed, their appearance can be simulated based on known parameters such as the position of astronomical objects relative to the surface and atmospheric composition.
