How can you view the galaxies?

To view any distant object in space you need a basic $150 telescope.


What instrument is used to view distant objects?

A telescope is an instrument used to view distant objects. Telescopes use lenses or mirrors to gather light and magnify images, allowing users to see objects that are far away, such as stars, planets, and galaxies.


Telescopes are placed in space to view distant galaxies primarily to?

Telescopes are placed in space to view distant galaxies primarily to avoid atmospheric distortion and light pollution, which can obscure and affect the quality of observations taken from Earth. Space telescopes also provide a clearer and more stable view of the universe, allowing for more accurate and detailed observations of distant galaxies.


What instrument is used to view objects in space?

A telescope is commonly used to view objects in space. Telescopes collect and focus light from distant objects, enabling astronomers to observe and study celestial bodies such as stars, planets, and galaxies.


Do all galaxies outside local group have red shifts?

Yes. Also, the size of the red-shift for all distant galaxies is directly proportional to their distance from us. This means that the space between us and all distant galaxies is expanding. Thus, Einstein's (initial) view that our Universe has been eternally stable in the location of matter must be false. No surprise that he referred to his early view as his "greatest blunder."


What is an instrument used observe distant objects with the eyes?

A telescope is an instrument used to observe distant objects, such as stars, planets, and galaxies, with the eyes. Telescopes gather and focus light to provide a magnified view of celestial objects. They come in different types, such as refracting telescopes and reflecting telescopes.


What device is used to view objects in the space?

A telescope is typically used to view objects in space. Telescopes gather and focus light to magnify distant objects like stars, planets, and galaxies, allowing us to see them more clearly. Telescopes can be used both on Earth and in space to observe and study the universe.


What instrument is used to view things that r far away?

A telescope is used to view objects that are far away by gathering and focusing light to magnify distant objects. Telescopes can be used for astronomical observations as well as to view distant terrestrial objects such as mountains or wildlife.


Telescope in a sentence?

The observatory had not yet opened, so we waited outside until it did.


What is the job the hubble space Telescope?

to take photographs of very distant galaxies, and show data of them to NASA. It is used, because there is too much light pollution in a lot of places on Earth, making it hard to use a telescope, but in space there is no light pollution (therefore, it can see the galaxies that we can't see on Earth).


What is the best way to study a black hole?

To view distant galaxies and stars and other 'bright' objects and analyse the suspected black holes effect. Effect being the movement around the black hole, or the loss of visual contact of that object.


Does science have a method or instrument for detecting black holes?

Black holes are distant objects found usually in the center of galaxies; therefore they are studied by astronomers, using telescopes, just as all astronomical objects are studied. Of course, black holes are studied indirectly. They do not emit radiation (or not enough radiation to view; there is Hawking radiation) but they have a strong effect on other nearby objects, which can be observed.
