Interferometry. First used in radio telescopes optical instruments were a "relatively" recent addition to the process. It is the interference of signals that is used to create resolution. The further the instruments are apart the better it works.

What is the angular size of the object in arcminutes when viewed through a telescope?

Ah, what a fantastic question! When you look at an object through a telescope, the angular size is simply how much of the sky it appears to take up. Imagine holding your thumb up to the sky – how many thumbnail widths could fit around the object? That's the angular size, and it's often measured in arcminutes, which is like the degrees on a compass but smaller to capture more detail. Just take a moment to appreciate the beauty of the universe and the small wonders it holds.

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.


What is the object that helps you to look at space?

A telescope is the object that helps you observe and study objects in space, such as stars, planets, and galaxies. Telescopes use lenses or mirrors to gather and focus light from distant celestial objects, allowing us to see them more clearly.


How do you use a refractor telescope to observe celestial objects?

To use a refractor telescope to observe celestial objects, first point the telescope towards the object you want to see. Adjust the focus by turning the focus knob until the object appears clear and sharp. You can also use different eyepieces to change the magnification. Keep the telescope steady and avoid any sources of light pollution for the best viewing experience.

What is the telescope's purpose or use?

The telescope's purpose is for scientists to be able to look into space and see what stars are made of and what the cycle of stars is. Some telescopes are public and anyone can look through them. But others are only for scientists. The telescope was invented by Galileo Galilei. You can see his finger in his very own museum! :0)

How does a telescope make a distant object look clearer?

It collects the light from the object and enlarges the picture using the lense, in other words, the glass at the end focuses on that object so you many see it better.


What are sources of Galileo?

The sources of Galileo is he wasn't the inventor of the telescope,but he was the first to use the telescope. Also he improved the telescope making an object look about 20 times bigger.Also,he made it magnify 3 times as much as before made this improvement in 1608-1609.
