How is space observed?
Things in space which release or reflect light, like stars or planets, can be seen either with the naked eye or with telescopes. By looking at that light, scientists can either directly tell where objects in space are, or at least can make deductions about their locations.
What are space observations?
ViewSpace is a free, web-based collection of digital interactives and videos highlighting the latest developments in astronomy and Earth science. ViewSpace gives you the opportunity to explore our planet, solar system, galaxy, and universe.
How do we know what objects in space are made of?
Frequency bands in a spectrum of light from an unknown object compared with bands from known samples can reveal the object’s composition.
What do we know about space?
No one knows exactly how big space is. This means we can “see” into space at a distance of almost 13.7 billion light-years. However, astronomers are not sure if our universe is the only universe that exists. This means that space could be a lot bigger than it appears to us.
Is used to observe space?
A space observatory is any instrument in outer space which is used for observation of distant planets, galaxies, and other outer space objects. A large number of observatories have been launched into orbit, and most of them have greatly enhanced our knowledge of the cosmos.
What is space observation answer?
The scientific observations on the different circumstances happening in the outer space with the help of modern science and technology is known as the space observation.

How can scientists tell the location of objects in space?
Things in space which release or reflect light, like stars or planets, can be seen either with the naked eye or with telescopes. By looking at that light, scientists can either directly tell where objects in space are, or at least can make deductions about their locations.
How are astronomers able to study the universe?
All known elements emit and absorb particular wavelengths of light, which is part of the electromagnetic spectrum. By studying the wavelengths of light (as indicated by ‘lines’ within the electromagnetic spectrum) emitted by an object in space, astronomers can get a range of information.
How can astronomers tell how far away a star is?
By studying the wavelengths of light (as indicated by ‘lines’ within the electromagnetic spectrum) emitted by an object in space, astronomers can get a range of information. One thing they examine is the change in position of lines in the spectrum from a star—this can tell astronomers how far away…
Why do we see different parts of the Moon?
What’s actually happening is that from our spot on Earth, we see different parts of the Moon lit up by the Sun as the Moon travels in its orbit. As the Moon travels around Earth, different parts of it are lit up by the Sun.
