Astronomers usually study an object by looking directly through a telescope true or false?
True =)
What are 3 basic categories of astronomical observation?
Imaging, which yields photographs (images) of astronomical objects; spectroscopy, in which astronomers obtain and study spectra; and timing, which tracks how an object changes with time.
What is a computerized telescope?
It is a telescope with a mount that has a GoTo system in it. It is like a small computer that you put in what object you want to see (eg. The Orion nebula) and then the telescope points at the object
Why are telescope eyepieces an important part of any visual telescope?
Telescope eyepieces are important of any visual telescope. It is the main part of the telescope and is what determines how the object will look like through the telescope.
What indicate redshifting to astronomers?
The object is moving away from the observer.

What is the main purpose of object lenses concave mirrors in the telescope?
Magnify images
How is the Hubble telescope different from a normal telescope used by astronomers on earth?
The main difference is that it is in orbit, above the atmosphere of the earth. This means that it can achieve a much better picture, since the light from the object in space wont be distorted by the atmosphere and its fluctuations. It means that the Hubble telescope can get away with using a much higher magnification.
How is a parallax helpful to astronomers?
Parallax is the apparent change in postion of an object when looked at from two different places. Astronomers use parallax to find how far away nearby stars are.
How astronomers study at the solar system?
Astronomers must learn physics, chemistry, mathematics and computer science...and how to use a telescope, astronomers must rely on their observation skills, for instance physics has helped astronomers to understand what makes spiral galaxies have spiral shapes, another is Spectroscopy which is the use of light from a distant object to work out the object is made of, When something is moving away from you, it stretches that waveform, while if it moves towards you it compresses the signal wavelength it emits. Spectroscopy also tells you a star's temperature, mass and surface gravity.

What is a flyby space probe?
It is a telescope placed in space (like the hubble telescope). When placed in space the telescope does not have to "look" through the earth's atmosphere so its images are not destorted.

Telescope eyepieces are important of any visual telescope. It is the main part of the telescope and is what determines how the object will look like through the telescope.
How big does the earth look from the Hubble telescope with the naked eye?
First off, your question is contradictory. You cannot look at any object with a telescope and with your naked eye at the same time. Naked eye means that you are looking at the object without any visual aid. The Hubble Telescope is never pointed at Earth. The Earth is too bright from that height and that high intensity could damage the Telescope's cameras. For pictures of the Earth from space, you can look up some images from the ISS or the Space Shuttle.
How is a telescope different from a sextant?
A Sextant is an instrument used to measure the angle between any two visible object and a Telescope is an instrument that aids in the observation of remote object by collecting electromagnetic radiation. By Artem Leo T. Delfin Pob. Sawang Loboc, Bohol
What is used to view the distance object?
A telescope.
