The Earth has been described as a "big blue marble" from space.
It has also been said to make astronauts realize that there are issues much bigger than the little problems we face daily, and that we are all part of a "bigger picture", if you can excuse the cliche.
From outer space, Earth appears very smooth and round due to its spherical shape. The atmosphere and oceans create a layer of haze that gives the planet a soft, blue appearance. Overall, Earth looks serene and relatively featureless when viewed from afar.
It makes the person look like something to be feared.
While you can see the clouds that float in the air, you do not see the atmosphere itself, whether you are on the earth or in space. You look through the atmosphere to see sea and land.
Auroras appear as vibrant curtains of light in varying colors such as green, red, and purple when seen from outer space. The lights are caused by solar particles interacting with Earth's magnetic field and atmosphere, creating a stunning display that can be seen from spacecraft and satellites orbiting the planet.

Shadows are caused by something BLOCKING the light. You can have shadows in space, if something is blocking the light. On Earth, shadows often look fuzzy; this is caused by the Sun's light being scattered in the air. In space, there is nothing to scatter the light, so shadows are sharp-edged and clear.
In space, the Earth looks like a blue marble. NASA has many photographs of the Earth from space. The earth is spherical like an orange but it is not orange.http://eol.jsc.nasa.gov/Collections/EarthFromSpace/land.htmhttp://www.wired.com/2014/12/digital-globe-best-earth-from-space-201
Astronomy is the study of the outer space. If you look up at the sky at night you are looking at outer space which is astronomy.
Because they were made the same time as the Earth from the same materials. And, since they have basically been frozen in time in outer space, they can tell us a lot about the composition of the Earth. The materials on Earth are constantly being recycled and nothing remains from the birth of the Earth, so that is why we look to outer space and the meteorites that fall to Earth to give us clues to its origin.
The earth is approximately a sphere (round like a ball). From any direction, its outline will be a circle.
It looks like a spiral disk, often with a hole in the center. See the links below for pictures
A void is an empty space. It can refer to an air pocket inside a rock formation, for example, or a region of outer space with no significant matter in it.
