What Makes Hubble Different From Telescopes on Earth? Earth’s atmosphere alters and blocks the light that comes from space.
Hubble orbits above Earth’s atmosphere
, which gives it a better view of the universe than telescopes have at ground level.
Why can space telescopes make sharper images than ground-based telescopes?
In space, however, telescopes are
able to geta clearer shot of everything from exploding stars to other galaxies
. Another disadvantage for ground-basedtelescopes is that the Earth’s atmosphere absorbs much of the infrared andultraviolet light that passes through it. Space telescopes can detect thesewaves.
Why do space telescopes produce clearer images than telescopes on Earth?
Because
the Hubble telescope is located in space, Earth’s atmosphere does not interfere with light from objects the telescope is aimed at
. This lack of interference allows it to obtain clearer images than ground-based telescopes with much larger mirrors.
Why is the Hubble space Telescope better than telescopes on Earth?
Earth’s atmosphere changes and blocks some of the light that comes from space. Hubble flies around, or orbits, high above Earth and its atmosphere. So, Hubble can
see space better than telescopes on Earth can
.
What are the disadvantages of a telescope?
The disadvantages are mainly to do with the hassle of operating in space.
It’s much more expensive
, so you can’t have such a large telescope. If things go wrong it’s much harder to repair them. You can’t update the instruments so often so they quickly become out of date.
Which is the biggest telescope in the world?
The largest visible-light telescope currently in operation is at
Gran Canarias Observatory
, and features a 10.4-meter (34-foot) primary mirror. The Hobby-Eberly Telescope at McDonald Observatory near Fort Davis, Texas, has the world’s largest telescope mirror.
Can we see Hubble from Earth?
Hubble is best seen
from areas of the Earth that are between the latitudes of 28.5 degrees north and 28.5 degrees south
. This is because Hubble’s orbit is inclined to the equator at 28.5 degrees. … In contrast, the ISS passes over much more of the Earth because its orbit has a higher inclination at 51.6 degrees.
Will Hubble be brought back to Earth?
The Hubble Space
Telescope is slowly falling back to Earth
. Years from now, the telescope’s blazing carcass might streak across the sky at hundreds of miles per hour. By the time the lumps of molten metal plop into the Pacific Ocean, the only instrument still intact will be its 2.4-meter mirror.
Are there colors in space?
Space emits a
range of wavelengths of light
, some we can see others we can’t. The majority of emissions are of red and blue light which are easily visible to the human eye but there are also UV, X-rays and gamma rays which are invisible.
What are the disadvantages of the Hubble Space Telescope?
Disadvantages. There are some limitations with the Hubble Space Telescope when imaging the Moon due to its sensitivity to light and it cannot image areas in the direction of the Sun. They are exceptionally expensive to build and position in place.
Maintenance is difficult
.
How far can Hubble see?
The farthest that Hubble has seen so far is
about 10-15 billion light-years away
. The farthest area looked at is called the Hubble Deep Field.
Can we see other galaxies?
Answer: Yes, you can see a few other galaxies without using a telescope! … The nearby
Andromeda Galaxy
, also called M31, is bright enough to be seen by the naked eye on dark, moonless nights. The Andromeda Galaxy is the only other (besides the Milky Way) spiral galaxy we can see with the naked eye.
What are 5 disadvantages of a refracting telescope?
- Very high initial cost relative to reflector.
- A certain amount of secondary spectrum (chromatic aberration) unavoidable (reflector completely free of this) The colours cannot focus at one point.
- Long focal ratios can mean that the instrument is cumbersome.
What are 2 problems with refracting telescopes?
The two problems with refracting telescopes are
a chromatic aberration and spherical aberration
.
What is a major disadvantage of a refracting telescope?
The disadvantages are mainly to do
with the hassle of operating in space
, It is much more expensive, so, you can’t have such a large telescope, If things go wrong, It is much harder to repair them, You can’t update the instruments, So, they quickly become out of date, Also with the modern technique of Adaptive Optics, …
