Because the main function of a telescope is to make things brighter. It does that
by collecting the light from an object over a much greater area than the lens of
your eye does.
-- The lens of your eye is maybe 1/2 inch in diameter.
-- The lens of the largest refracting telescope is 40 inches in diameter, so it can collect
6,400 times as much light from a star as your eye can.
-- The mirror of the largest reflecting telescope is 400 inches in diameter, so it can collect
640,000 times as much light from a star as your eye can.
What else can I help you with?
What nebulae can you see without a telescope?
Some nebulae that can be seen without a telescope include the Orion Nebula (M42), the Lagoon Nebula (M8), and the Andromeda Galaxy (M31). These objects are bright enough to be visible to the naked eye under dark skies.
Is some nonmetals are invisible?
No, nonmetals are not invisible. Nonmetals such as oxygen, nitrogen, and carbon are visible in their gaseous form as they make up the air we breathe. Other nonmetals like sulfur and iodine can be seen in their solid or liquid forms.
Can you see a supernova from earth without a telescope?
Yes, under the right conditions, a supernova can sometimes be visible from Earth without a telescope. However, most supernovae are too faint to see with the naked eye, so a telescope or binoculars are usually needed for observation.
Can you see an asteroid without a telescope?
Yes, some asteroids can be seen with the naked eye when they are close enough to Earth. These asteroids are typically bright and are moving across the night sky.
What isa aenormus telescope floating in space that sends pics back to earth called in general?
Hubble space telescope and international space station!
Are some constellations noticeable?
Yes, all constellations have at least some stars that can be seen with the unaided eye.
Why can a comet be seen for years and an asteroid may be invisible on earth?
Some comets might also be invisible from Earth, we only see the big ones.
What are some invisible things?
Some examples of invisible things are air, emotions, and radio waves. These are elements or phenomena that cannot be seen with the naked eye but still exist and play a role in our daily lives.
What nebulae can you see without a telescope?
Some nebulae that can be seen without a telescope include the Orion Nebula (M42), the Lagoon Nebula (M8), and the Andromeda Galaxy (M31). These objects are bright enough to be visible to the naked eye under dark skies.
What examples of objects that can be seen with the unaided eye?
Objects that can be seen with the unaided eye include the moon, planets like Venus and Mars, stars, constellations, and bright comets. Additionally, some deep sky objects like the Andromeda Galaxy and the Orion Nebula can also be seen with the naked eye under dark sky conditions.
What advantages would a telescope in space have over a telescope on earth?
The main advantage would be the absence of an atmosphere. Any telescope on earth can only "see" electromagnetic (light) waves after they have travelled through the atmosphere, losing some of their directional integrity, which distorts the image seen in earth bound telescopes. Some light waves never make it to the telescope at all.
Are some nonmetals invisible?
No, all elements in the periodic table are made up of atoms that can be seen or detected using scientific instruments. Some nonmetals may have properties that make them difficult to see with the naked eye, but they are not invisible.
Do some mermaids have invisible tails?
It is really hard to say since mermaids are mythological creatures and no one has ever seen one.
What are some examples of some common nouns that are invisible?
Some examples of common nouns that are invisible include concepts such as love, justice, and time. These nouns represent abstract ideas or qualities that cannot be seen with the naked eye but are understood through their effects and manifestations. While they may not have a physical form, they play a significant role in human experiences and interactions.
What are micro-orgasims?
Micro-orgasims are very small particles that you can see under a microscope.
Are amoebas large or small organisms?
They are microorganisms, consisting of only one cell, and they are so small that they cannot be seen with the unaided eye. Some organisms are smaller than amoebas, but they are still very small.
Which layers of the Sun can be seen with some type of telescope?
The photosphere can be seen with visible-light telescopes, while the chromosphere is most easily observed with ultraviolet telescopes and the corona with X-ray telescopes.
