Telescopes

Rilles, which are long, narrow depressions on the lunar surface.filesize Gorge, which are cliffs or escarpments. They are formed by tectonic stresses or volcanic activity. And small craters, which are impact structures caused by meteorite strikes.

Hubble stays in orbit around Earth by traveling at a speed of about 17,500 miles per hour, which allows it to counter the gravitational pull of Earth and maintain a stable orbit. It orbits at an altitude of around 340 miles above Earth's surface, completing a full orbit roughly every 97 minutes. Additionally, it occasionally uses its thrusters to adjust its position and trajectory as needed.

Aluminum is commonly used to form a corrosion-proof reflective coating on telescope mirrors. The aluminum coating is applied through a process called thermal evaporation or sputtering, creating a highly reflective surface that improves the telescope's performance.

To set up a Meade telescope, start by assembling the tripod and mounting bracket. Attach the telescope tube to the mounting bracket, ensuring it is securely in place. Next, align the finderscope with the main telescope optics and calibrate the viewfinder. Finally, balance the telescope properly and power it on to start observing the night sky.

The Cosmic Background Explorer (COBE), also referred to as Explorer 66, was a satellite dedicated to cosmology. Its goals were to investigate the cosmic microwave background radiation (CMB) of the universe and provide measurements that would help shape our understanding of the cosmos.

In past years, the light collecting power of telescope has been improved by building telescopes with of larger diameters with larger collecting areas, thus allowing for the detection of fainter and more distant objects

Telescopes have evolved from simple lenses in the 17th century to advanced systems today, utilizing mirrors, lenses, and electronic sensors. They have increased in size and power, allowing us to observe deeper into space and with greater accuracy. Modern telescopes can be ground-based or space-based, enabling astronomers to make groundbreaking discoveries about the universe.

If by resolution, you mean the closest pair of stars that can be seen in a telescope, it is purely a function of the size of the mirror/lens.

You can calculate it as 134÷D where D is the diameter expressed in mm or 4.5÷D where the diameter is expressed in inches.

So for my 12 inch Meade Telescope the resolution is 4.5÷12=0.375 seconds

Only because it gets no atmospheric interference, which most of the ground based telescopes do.

The telescope is an instrument that is used to study or observe objects that are a long distance away. It is an important instrument in astronomy since it helps in observation and measurement of the distance between the earth and objects in the galaxy.

False. Astronomers usually study objects in space through telescopes that collect and analyze data using sensors and instruments. They then analyze this data on computers to make observations and draw conclusions about the object.

The first telescope was invented in the early 17th century by Hans Lippershey, Zacharias Janssen, and Jacob Metius. The process of developing the first telescope took a few months to put together the design and components.

Astronomers use fewer lenses in telescopes to minimize light loss due to absorption and reflection by the lenses. Each additional lens in the optical path can reduce the amount of light that reaches the eyepiece, affecting the image quality. Additionally, fewer lenses can help reduce chromatic aberration and other optical imperfections.

Large lenses deform under their own weight, but mirrors can be supported. Reflectors do not suffer from chromatic aberration like refractors do. Large mirrors need only one optical surface, achromats four surfaces to grind.

Large, very clear lenses are harder to cast than more tolerant mirror blanks.

The primary mirrors on the Keck Telescope are 10 meters (33 feet) in diameter. Each mirror is composed of 36 hexagonal segments that work together to form the complete reflective surface.

Laurent Cassegrain, a French priest and astronomer, invented the Cassegrain telescope in the mid-17th century. The design features a concave primary mirror with a secondary convex mirror, allowing light to be reflected back through a hole in the primary mirror for viewing.

Light refracts when it passes across the boundary of two media having different optical densities (refractive indexes). If the light stated in the question had done this, then it is refracted.

A refracting telescope works just like a magnifying glass. It uses a convex glass lens (to bend light and bring it into focus. This lens is thicker in the center than it is toward its edges, which bends the light more at the edge of the lens than light coming through the center. This allows all of the light to come together at a focus point. The point of focus is where the image is created.

If someone looks into the eyepiece, a concave lens magnifies the image

Refracting telescopes have two main problems-images are not always clear because the light is being bent and the size of the lens is limited (which limits the power of the telescope).

There have been a number of problems with the Hubble Space Telescope over the years. Possibly the most serious was that the primary mirror of the telescope was incorrectly made; it was out of focus! Since there was no way to test it prior to launch, scientists didn't discover this until AFTER it had already been launched from the Space Shuttle and released into orbit. It was a GIANT disappointment. (The Hubble Space Telescope couldn't be tested on the ground, because the structure isn't strong enough to support its own weight in gravity.)

For almost a year, the Hubble's telescope was as blind as man with broken glasses. Another Shuttle mission was required to install a corrective lens and bring the pictures back into proper focus.

Since then the biggest problems have been batteries, computer systems and gyroscopes; several gyros have been replaced, and the main computer was replaced, and new more powerful instruments installed just this summer. At the moment, I believe that everything is working properly.

Visible light is about 350-700 nm, so infrared radiation would have a wavelengt above 700 nm (0.7 microns), approximately. It is not a single wavelength, but a wide range of wavelengths. The upper range is about 300 microns. Wavelengths above that are called microwaves.
