What can be seen on earth from space?
There is a longstanding myth that the Great Wall of China is the only manmade object visible from space. It and several variations on the theme are great fodder for water cooler arguments. In reality, many human constructs can be seen from Earth orbit. Shuttle astronauts can see highways, airports, dams and even large vehicles from an Earth orbit that is about 135 miles (217 kilometers) high. Cities are clearly distinct from surrounding countryside, and that's true even from the higher perch of the International Space Station, which circles the planet at about 250 miles (400 kilometers) up. "You can see an awful lot from space," says astronaut Ed Lu, the science officer of Expedition Seven aboard the station. "You can see the pyramids from space, especially with a pair of binoculars. They are a little difficult to pick out with just your eyes." Egyptian pyramids have been photographed from space several times with standard digital cameras and high-powered lenses. The largest pyramid at Giza, on the outskirts of Cairo, is 745 feet (227 meters) wide and 449 feet (137 meters) tall. "With binoculars you can see an awful lot of things," Lu wrote via e-mail in fielding a question from an Earthbound space fan. "You can see roads. You can see harbors. You can even see ships; very large tankers on the ocean we can see using the binoculars." There are some surprises, too. "You can see airplane contrails, and occasionally at the end of an airplane contrail, you will see a glint of sunlight off the airplane," Lu says. "And very occasionally, you do see other satellites go by. It is kind of a neat thing to see." There are of course places in space from which you can't notice how humans have sculpted the planet. Apollo astronauts could not make out manmade features from the Moon, for example. And from Mars, Earth would appear to the naked eye as nothing but a bright "star" in the night sky. So what about the Great Wall of China? "You can see the Great Wall," Lu says. But it's less visible than a lot of other objects. And you have to know where to look. In fact stretches of the wall aren't even visible from China. They've been buried by sand for centuries. NASA has used space-based radar to map out hidden parts of the ancient structure. Lu is trying to get a picture of it, too, with a digital camera. "The weather hasn't cooperated," he says. "There has been a lot of clouds and haze over that area since I've been trying. But I hope to be successful before I come back down."

Using the Hubble Space Telescope we have seen 13 billion light years into space, these are some of the very first galaxies to form after the big bang. [Search for "hubble space telescope ultra deep field images" to see the actual images.] Although technology is always improving, we can never see …much further than this point in time. The problem is the time it takes for light to travel to Earth. The light we see from these very first galaxies have been travelling for 13 billion years to reach us, so really we are looking back in time. In them 13 billion years the light has been travelling to us, the universe has already expanded another 13 billion years. The reality is that many of the stars that make up these galaxies no longer exist in the same way we are seeing them today. Theoretically, if the edge of the universe emitted visible light and stopped expanding today, we would still have to wait 13.7 billion years (the current age of the universe) before we would be able to notice. Therefore how far we can see is always governed by the time it takes for light to reach us. If you think about it - the light we see from these very first galaxies was emitted before life and the Earth even existed! Bare in mind that light travels so fast it could go around the Earth 7 times in 1 second... ( Full Answer )
No Rainbows are caused by sunlight glinting off tiny water particles in the sky, bouncing the light back towards the observer. In other words, any time you see a rainbow directly in front of you, the Sun is directly behind you, and your shadow points at the center of the circle the rainbow is desc…ribing. ( Full Answer )
The 'sky' in space is an inky blackness. The sky as we know it is not seen from space as it is just the way light refracts in our atmosphere. Looking down at the earth from space, you cannot see the blue sky, only clouds, land and water. \n. \n \n. \n
No, Antarctica is not the only place that has been seen from space by astronauts. It has been said that one can clearly see the Great Wall of China from space. Also there are certain places on earth that are clearly seen from space because of it's certain type of peculiarity. It is said that the be…am of light from the Luxor Hotel & Casino in Las Vegas can be seen from space. ( Full Answer )
Earth is located in the milky way galaxy. In the milky way galaxy we are located in the solar system and is the third planet from all eight planets. We are also the only known planet which can support life.
Yes. Jupiter is the third brightest object in the night sky. Onlythe moon and Venus are brighter.
Because sound needs a material medium to travel through, and can't go anywhere through the vacuum of space. Besides, even if it could, it would take sound ... moving at the speed of sound ... 874 thousand years to cover one light year of distance. We'd still be hanging around waiting to hea…r the supernova that was discovered in 1054 AD. ( Full Answer )
The Great Wall of China was said to be the only man-made structureon earth visible from space. However astronauts have tried to seeit and failed. If you go on Google Earth or similar you can try tofind it from an altitude of 100km (the official "edge of space").The problem is not the length, but the… width of the wall. Itsnarrowness makes it invisible. At night, lights from major cities may be visible. Cities wouldcount as a man-made structure. During the day, cities and airportsare visible from low Earth orbit. At a distance of several thousand miles, only clouds, continents,ice caps, and major bodies of water are visible (weatherpermitting). Nothing man-made except the lights of cities can beseen from the Moon. A recent addition to the "visible from space" collection of Earthlyobjects are the Athabasca Oil Sands projects in Alberta Canada.These are vast open pit mines which allow the removal of sandssaturated with heavy bitumen for oil recovery.

Yes, the Himalayas can be seen from space, as it is part of Earth, considering it to be about 2,400 metres long and 350 km wide. If from a certain angle, the height/elevation of it can be seen. If viewing the top view, it would look like jagged surfaces covered with snow and ice (white in colour).
If i bright loud explosion occured in space it wouldn't be heard due to the vacuum of space. And a sound wave requires a medium(stuff) to travel through. However the light would be seen as light doesn't need a medium to travel through.. This can be proven by the fact we have observed HUGE explosion…s in space (stars turning into red giants or going super nova which means explosion) We see the light but we will not hear the explosion. ( Full Answer )
im guessing its in space becasue t needs room and if it wasent in space the earth would just blow up
Mostly blue and white. The Earth is 75% covered with water, and much of the Earth is covered with clouds.
Sound travels through air or solid material. There is no air inouter space. Adding on would like to mention that sound waves required medium totravel, in order to do so it must have a conductive medium, whichspace doesn't have since there is vacuum out there. So it doesn'treach us.
Jupiter is so big that it can be seen from earth with out a telescope
None of the pyramids are large enough to be seen without opticalaid (like a telescope) from altitudes high enough to be considered"space". The largest pyramid ever constructed, is the QuetzalcÃ³atlPyramid at Cholula de Rivadavia, 101 km (63 miles) south-east ofMexico City. It is 54 m (177 ft) tall…, and its base covers an areaof nearly 18.2 ha (45 acres). That only corresponds to a squareabout 63 meters on a side - around half an American football fieldor international football (soccer) pitch . Hopefully you realizethat football fields and football pitches are not visible fromspace. ( Full Answer )
have you not seen a photo of the earth taken from space? its just a haze around the earth.
It is a myth that the Great Wall of China can be seen from space. There are no man-made features on Earth that are visible with the naked eye from the Space Shuttle's windows. On the night-side of Earth, of course, it's a different story; you can't see individual lights, but the vast swath of ligh…ted cities is easily visible. The only exception is reservoirs. You cannot see the dams themselves, but the larger lakes are visible. ( Full Answer )
Most lasers can be seen, and yes a green laser beam can be seen in space. But some lasers are really strong so we can't see them.
You are probably thinking about the Great Wall of China. There is an urban myth that it can be seen from space. But it can't be seen with the unaided eye. When you use telescopes or binoculars, or perhaps a camera with a zoom lens, then you can see the Great Wall. But you can see many other object…s as well if you use those devices. Some of the telescopes that are in orbit can read the license plate on a car. It is difficult to see the Great Wall because it is very narrow and winding. It is crossing hills and valleys. There are other things that are easier to see such as bridges and dams, reservoirs and lakes, and cities at night. Two of the easiest things to identify at night are the Nile and Rhine rivers. There are many boats that travel on them at night and many lights along their banks. ( Full Answer )
Given the development of technology in recent years, almost anything bigger than a fist can be in detail, and according to some conspiracy hypothesists objects no bigger than an ant may be discernible.
many things, motorways, ships, railways, cities, fields, and some individual buildings. space is close to the earths surface, about 60 miles (100 km) off the ground is technically where you reach space. no man made structures can be seen from the moon
The great wall of china is one man made landmark that can be seen from space, the amazon river is a natural landmark that can be seen.
You need to make you question more clear. ===== To another contributor, it's crystal clear, and he offers this method of procedure: -- Go outside during daylight. -- Find a piece of bare, unimproved ground, i.e. not excavated, constructed on, or paved over, and stand on it. -- Stand c…omfortably, with feet parallel and approximately shoulder-width apart. Allow hands and arms to hang relaxed at the sides. -- Bend the trunk slightly forward at the waist. An angle of 3Â° to 5Â° from the vertical is typically adequate, but in the event of obesity, increase the angle accordingly. -- With the angle properly adjusted, the physical position is comfortable, and the vertical line of sight is unobstructed by any part of the observer. Focus the gaze in the negative-z direction. -- The surface in view is a part of the exterior surface boundary of the earth. In principle and in time, the entire surface can be viewed, in elemental piecewise components, although the scope of that project might well render it impractical. ( Full Answer )
Yes the Earth and out solar system is in space they are also in the Milky Way galaxy along with hundreds of billions of other stars.
What is seen when you see the earth from below i.e. when we go in outer space by a spacecraft and then go below earth from sidewards what is then seen?
The Earth is pretty much spherical, or ball-shaped. (Technically speaking, it is an "oblate spheroid", which means a "lightly squished ball".) It looks like a ball from every perspective. When you look at the Earth from the other side, you see different geography, but it's still a ball. If you wer…e to go out in space and travel around the world, it would look very much like a globe - except that globes don't have clouds, and the Earth does. ( Full Answer )

Yes. In fact, from far enough away, you can see the phases of the Moon and the Earth, side by side.
The Moon always keeps the same side facing the Earth. So, whatever direction you name, there is some place on the Moon from which the Earth appears in that direction, and if the observer doesn't move to a different place on the Moon, then the Earth doesn't move either. It's always in the same d…irection. The concept of "Earth rise" or "Earth set" does not apply on the Moon. (This video from Apollo 8 came as the spacecraft was circling the Moon in orbit.) Note that for about half of the Moon's surface (the far side), the Earth is never visible. During the full moon, very little of Earth is illuminated by the Sun, as seen from the Moon. ( Full Answer )
No, ozone layer can not be seen from the earth. It is just atransparent blanket of thin air.
the phases of the moon from earth are seen in order, from new moon (starting of a month), to waxing crescent, to 1st quarter, waxing gibbous, to full moon, waning crescent, to 3rd quarter, to waning gibbous, then it starts back again. this order takes about 4 weeks to complete (or a month, whatever …you prefer). notice that when a waxing moon is showing, every night the bright side of the moon gets bigger, and waning gets smaller. Hope this helped! ( Full Answer )
If you have never seen the Moon, look up to the sky ! It is not always above the horizon, but when it is, it can be seen very clearly.
The light of a star that can be seen from earth is actually lightfrom many years ago. Since stars are so far away from our planet ittakes thousands of years for their light to reach us.
Arcturus is about 37 light years from us. Earth would not be visible from that distance. Voyager 1 took a photograph of Earth at a distance of 6.1 billion kilometres (0.00064478428 light years) and it appears as a single pixel.
Yes, if you go out at night you can often see polar satellites. They look like stars moving at a regular speed though the sky, heading either North or South.
Space junk, in others words is trash floating around our Earth caught in a circular orbit. Space junk has caused problems and I will happily list a few for the answer. For one, if it is biggest enough sometimes it will fall back to the Earth and unlike most things, not burn up in the atmosphere and …come crashing to Earth which itself poses dangers. Another is moving space junk can become problems to space stations. Damage, severe or little can be caused by junk ramming into the station. More problems it poses by space shuttles can, sometimes, hit space junk which you can figure is a problem. More or less Space Junk in other words is pollution in space. ( Full Answer )
A lunar eclipse is visible from any place on Earth from which the moon is visible while the eclipse is in progress. Since the lunar eclipse takes place at the time of Full Moon, and the Full Moon is exactly opposite the sun in the sky, this means that the lunar eclipse is visible from any p…lace where it is night, i.e. the sun is down, while the eclipse is in progress.

mars can be seen many nights every year. unlike the circulating hoax email, mars is not visible as big as the moon, only a bright star, seeing as it is just over 300 million kilometers away. it can be seen this year in the western sky as a red star, just to the top right of venus, which is just abov…e the horizon resembling a large yellow star.

There will be a Transit of Venus on June 5/6, 2012, depending on which side of the International Date Line you're on. The best views will be from Guam or perhaps Japan on June 6; Guam often has cloudy weather.
All of the planets can be seen from Earth, but a telescope or a powerful set of binoculars may be needed to see Uranus and Neptune. All of them cant be seen at certain times, when they are on the opposite side of the solar system on the other side of the sun for example.
In the Film "Hercules", portrayed by James Woods. Or when he was spat out by Chronos.
yes but you would not know you was looking at a binary unless you knew its location or you had special equipment to make it out. or a big enough telescope.
No, it cannot be seen from space. Not even the Great Wall of China can be seen from more than 160 km altitude. It's only a myth.
The Earth is blue because the O-zone layer is blue and creates the dominant color in the earth's atmosphere so that even from space the earth appears blue
Well, first of all, Venus is permanently and completely covered by dense clouds, so if you were living on Venus, you would have no idea what stars and planets are, and maybe not even what a sun is. But if you could somehow see through the clouds from the surface of Venus, here are a few things you'…d see in the sky: -- the sun ... bigger, brighter, and hotter than it appears from Earth -- Venus takes 224 days to circle the sun once ... and about 20 days longer to rotate once on its axis ... which it does backwards . I can't decipher right now what that means in terms of the length of 'daylight', but trust me, it's weird, and very long. -- You would see the exact same stars and constellations from Venus that you see from Earth. Instead of rotating around the whole sky once every 24 hours, it would take them 243 days. Polaris would not be the center of their rotation. -- You would see a "double planet" drifting through the stars, very bright, and always very close to being over your equator. The larger, brighter one would be distinctly blue-green, and you could see clouds on it through a small telescope. The smaller, dimmer one, that always stayed close to it, would be a dull grey color. If you watched the pair for a while, you'd notice that the smaller one seemed to wiggle back and forth, and was actually revolving around the larger one. They would be quite ineresting to watch when they were close to Venus. At times, the smaller one would pass in front of the larger one, dimming it and obscuring some surface features if you were watching through a telescope. And at other times, the smaller one would pass behind the larger one, and couldn't be seen at all for a while. For casual observers, this double planet, and the show it put on, would be the most interesting thing going on in the night sky of Venus. Its antics would be familiar to many people, but for those who hardly ever looked up at night, this pair of objects would be the source of thousands of questions here on WikiAnswers. That bright, beautiful "double planet" as seen from Venus, would be the Earth and its moon. ( Full Answer )
well if you feel a firing inferno coming towards you at great speeds from space, all you need to do is to look up and there you have it :)
In outer space, you can see the Earth, as well as planets, moons, the sun, and other stars, without being hindered by the Earth's atmosphere. It is much clearer, and having the Hubble space telescope in Earth orbit allows it to see much more than any optical telescope could ever see on the Earth's s…urface. ( Full Answer )
As a normal everyday individual, we don't get the chance to see what earth looks like from space in person like astronauts do. Instead we we can search websites such as Google image to see pictures of earth from space.
Anything that is too far away or doesn't emit enough light. No planetoid can't be seen with the naked eye. Most stars, even the closest ones, can't be seen with the naked eye, since they are too faint to be seen - the stars that you do see have an above-average brightness. Comets - such as the one…s in the Oort Cloud - can't be seen even with telescopes, unless they happen to come fairly close to us. The farthest known galaxies can be seen with large telescopes, but the individual stars cannot be seen. Etc. ( Full Answer )
No, and this has been shown time and again by photographs taken byastronauts. Although built environments such as towns and citiescan be made out, no political boundaries of any kind are observedlooking at Earth from outer space. Political boundaries areman-made social constructs, not physical or na…tural ones. Countriesor sovereign states are artificial social entities also created bypeople and not physical or natural ones which can be observeddirectly.
