Telescopes
A telescope is a device used to form images of distant objects. There are two kinds: an optical telescope uses lenses and is known as a refracting telescope or a refractor, and a reflecting telescope, which uses a mirror and is known as a reflecting telescope or a reflector. The earliest telescope was a refractor built by the Dutch eyeglass maker Hans Lippershey. This category is for questions related to telescopes, including using them to view distant planets and objects in space.

When observing Pluto from a distance of 5.91 trillion miles (5910000000000 miles), you would be looking at Pluto as it was about 4 hours and 4 minutes ago. This is because the speed of light is finite and it takes time for the light from Pluto to reach the telescope on Earth.
Inside a telescope, you will find lenses or mirrors that collect and focus light from distant objects. These components work together to magnify and enhance the image of celestial bodies for observation.
Where is kamarias son in the telescope on Panfu?
First, go on to the volcano. When you are there, click on the telescope. There, look into the bottom left corner. Then click onto the yellow spot! Hope I helped, Riimzz.X
What do radio telescopes use to gather and forces radio waves?
Radio telescopes use large antennas to gather radio waves by focusing them onto a receiver. The receiver amplifies and converts these radio waves into electrical signals that can be analyzed by scientists to study celestial objects and phenomena in space.
Is Orion visible at 11 pm on the Fourth of July?
No. The best place to see Orion from is on the equator ... that's where it spends the most hours
above the horizon.
Even there, on the 4th of July, Orion isn't completely risen until 6 AM, and it's completely set
by 6 PM. So July seems like a particularly poor time to try and see Orion.
The primary problem overcome by radio interferometry is the limited resolution of individual telescopes. By combining signals from multiple telescopes, interferometry creates a virtual telescope with a larger diameter, which improves the resolution and allows astronomers to see finer details in the radio sources being observed.
What can you find about a star when using telescope?
When using a telescope, you can observe a star's brightness, color, size, and distance from Earth. Depending on the telescope's capabilities, you may also gather information about a star's temperature, composition, and movement through the sky.
How many feet are there in 106 meters?
There are 0.3048 metres in one foot. Therefore, rounded to two decimal places, 106 metres is equal to 106 / 0.3048 = 347.77 feet.
Which is bigger a reflecting or refracting telescope?
Reflecting telescopes tend to be larger than refracting telescopes because they do not suffer from chromatic aberration, allowing for larger apertures and therefore more light-gathering capability. This makes reflecting telescopes popular for professional observatories and research purposes. Refracting telescopes, on the other hand, are limited in size due to the weight and cost constraints of large glass lenses.
Increasing the distance between the two most widely separated radio telescopes has an enormous effect on resolution.
Why is it important that the solar system is in a quiet part of the galaxy?
It is important that the solar system is in a quiet part of the galaxy because a location away from high levels of radiation, cosmic rays, and supernovae increases the likelihood of habitability. These conditions reduce the risk of catastrophic events that could disrupt the stability and development of life on Earth.
What are the use of prisms in telescopes?
Prisms are used in telescopes to correct and enhance the image quality by reducing optical aberrations and improving the clarity and sharpness of the image. They can also be used to flip the image orientation so that it appears right-side up when viewed through the telescope. Additionally, prisms can help to increase the focal length of the telescope, allowing for higher magnification of distant objects.
What telescope discovered black holes?
Black holes,were theorized since the 1800's,it was predicted by Einstein's theory that they were really real.Since then this forced astronomers to think such a thing is real,and yet they are,but there very rare to find,so we don't really know what telescope discovered a black hole.So we thing the Hubble telescope did because well,its the hubble telescope.
Why do telescopes need to track objects?
Telescopes need to track objects because Earth's rotation causes celestial objects to appear to move across the sky. By tracking the object, the telescope can maintain a steady focus on it, allowing for clear and detailed observations over an extended period of time.
Who developed the modern telescope for space exploration?
The modern telescope for space exploration was developed by NASA in partnership with other space agencies. Instruments like the Hubble Space Telescope and the James Webb Space Telescope have been designed and built by teams of engineers and scientists to observe the universe from space.
When was the planck telescope built?
The Planck telescope was launched on May 14, 2009. It operated for about four years, until October 23, 2013, collecting data on the cosmic microwave background radiation.
The largest optical telescope has four 8.2 meter?
Mirrors,
The Hubble space telescope first had one big shaped mirror, which made the images blury so they sent up astronaughts and replaced it with 4 8.2 meter flat mirrors making the pictures more clear!
Who invented the telescope in renaissance?
The telescope was not invented during the Renaissance; it was first attributed to Dutch eyeglass maker Hans Lippershey in the early 17th century. Galileo Galilei is then credited with making significant improvements to the design and using it for astronomical observations.
How do you fixs the penguins telescope?
To fix the penguin's telescope, you can start by cleaning the lenses with a soft microfiber cloth. Check for any visible damage or misalignment in the telescope's components and try to realign or repair them if possible. If the issue persists, consult an expert or the telescope's manufacturer for professional assistance.
The light-gathering power of a telescope varies with the of the diameter of the lens or mirror?
Yes, that is correct. A greater main mirror, or main lens, will gather more light.

What does the hubble space telescope look at?
The main purpose was to collect pictures, as it was, and is, a very high-tech and high-quality telescope. It was constantly take billions of pictures throughout each day, and send them back to NASA.
What is the main optical element of a refracting telescope?
The main optical element of a refracting telescope is the objective lens. This lens collects and focuses light from distant objects, forming an image that can be magnified and observed through an eyepiece.
If you wanted to study a neutron star would you use a visible light telescope or an x ray telescope?
Mostly neutron stars are detected with radio telescopes. Some can actually be seen with optical telescopes, and these are all optical pulsars.
Neutron stars were discovered because they are radio sources. The first star known to be a neutron star was the Crab Nebula neutron star, or Crab Pulsar, which was discovered to be a neutron star because of its radio emissions in 1965. Its apparent magnitude is 16.5. This puts it beyond the abilities of most amateur telescopes.
