May 4, Unfortunately the answer to this question is no. The raising of the flag would be a symbol of our nations goal that began with President John F Kennedy's pledge to Congress on May 26 th "I believe this nation should commit itself to achieving the goal before this decade is out, of landing a man on the moon and returning him safely to the earth.
Thus the flag which should have been flat had its own permanent wave" Is the flag still standing? Even a Welcome to Telescopes August 11, Backyard astronomy is a fun and rewarding hobby that can Thank you for subscribing! But can you? The question here is one of resolution: how big does an object have to be before a telescope can resolve it, that is, see it as more than just a dot?
As an example, a person standing next to you is easy to see and easily identifiable. But from a mile away that human is far more difficult to see, and from ten miles away is just a dot if that. The ability for a telescope to resolve an object is, as you'd expect, directly related to the size of the mirror or lens. What does this mean?
An arcsecond is a measure of angular size how big an object appears to be -- if two objects are the same physical size, the one farther away will appear smaller, and have a smaller angular size. There are arcseconds to a degree, and to give you an idea of how small a measure this is, the Moon is about 0. D is the diameter of the mirror in centimeters. Hubble's mirror is 2. Plugging that into the formula, we see that Hubble's resolution is That's an incredibly small size; a human would have to be nearly kilometers miles away to be 0.
To be totally accurate, there's a twist to this. Well, really two. The first is that there's a wavelength dependence too; for a given telescope size, the shorter the wavelength the more resolution you get a telescope will resolve blue objects better than red ones, since blue has a shorter wavelength. But this is pretty minor compared to mirror size, and we can ignore it here plus it's already compensated for in the constant The shadows on the surface will be more pronounced, and help distinguish features you might otherwise miss.
Looking at the Moon with only your eyes, you see mostly areas of white and gray. These gray patches are solidified volcanic lava flows. The lava was similar to the basalt that erupts on Earth and, like on Earth, cooled to form a relatively dark-colored rock. We call these areas the lunar seas, or maria. The lighter-colored areas are called the highlands, and show the earliest crust on the Moon, dominated by a type of rock called anorthosite, which is primarily made up of the white mineral anorthite or plagioclase.
What you see on the Moon with your eyes only will vary depending on your eyesight.
