Telescopes

It is likely a spiral galaxy. Spiral galaxies are characterized by their pinwheel shape and are composed of a central bulge surrounded by spiral arms containing stars, gas, and dust. Examples of spiral galaxies include the Milky Way and the Andromeda Galaxy.

Light goes through the lens but not through the mirror.

-- So any imperfection inside the lens can affect the behavior of the light, but an

imperfection inside the mirror can't.

-- So the lens must be made of the finest, purest material through and through,

but the mirror can be made of any material that can hold the shape of one surface ...

metal, granite, etc. The mirror doesn't even have to be glass.

-- Both surfaces of the lens must be accurately curved and polished, and they

must be perfectly parallel to each other. Only one surface of the mirror has to

be optically perfect in shape; the others can be pocked, dimpled, honeycombed,

scratched, drilled, chipped, etc.

-- The lens can only be supported by its edge, and must be rigid enough that no

part of it will bend or deform under its own weight, no matter what position it's

in. The mirror can be supported all around its sides and all over its back. It can

even be fitted with computerized plungers along its back, to push on it and

correct its shape if it sags or bends.

The refracting telescope was invented around 1608 by Dutch eyeglass maker Hans Lippershey.

There are a variety of styles of reflecting telescopes, but I will describe one of the easier and more common designs. The primary mirror is curved concave. It is created typically out of thick glass that has been ground and polished to remarkable precision, which is then coated with reflective material. It can also be fashioned from a reflective metal.

A second, flat mirror (typically oval-shaped) is positioned at the focal point of the primary mirror at an angle to reflect the light into an eye piece. These are the major components: the curved primary mirror, the flat reflective mirror, and the eye piece, which is typically a magnifying lens.

The reflecting telescope was invented by Sir Isaac Newton in the early 1600s. This was before there was a patent office, and no patent exists on the reflecting telescope as such. The Dobsonian mount is a popular alt azimuth mount for reflecting telescopes, created by John Dobson in the 1960s. He apparently never applied for a patent for this.

A degree in engineering or computer science is likely to offer job opportunities with salaries in the 60 to 70 thousand rupees range. These fields are in high demand and offer good earning potential for graduates. Additionally, gaining relevant work experience and certifications can help increase earning potential.

to take photographs of very distant galaxies, and show data of them to NASA. It is used, because there is too much light pollution in a lot of places on Earth, making it hard to use a telescope, but in space there is no light pollution (therefore, it can see the galaxies that we can't see on Earth).

The Pano mirror lens is a great tool for taking 360° panoramic photos with the minimum of fuss:

1- Mount the Pano Pro unit and your camera onto your tripod, pointing vertically upwards, using the supplied quick-release adapter kit.

2- Focus the camera on the mirror and take one shot.

3-Use the FREE software to process your image into a 360° panorama.

Money, it all comes down to money. The Hubble telescope is a multimillion dollar thing, i think its total cost is in the billions. So imagine what a better one would cost! Plus, the Hubble telescope has been able to do everything we needed it to. So until it can't keep up, i think we will keep good old Mr Hubble.

The asteroid 107P was named "Hubble" after the Hubble Space Telescope. This was done to honor the contributions of the telescope to astronomy and space exploration.

The Kepler space telescope was built by NASA's Ames Research Center in collaboration with Ball Aerospace. It was launched in 2009 with the primary goal of searching for exoplanets.

The Chandra X-ray Observatory operates in space because Earth's atmosphere absorbs X-rays, preventing them from reaching ground-based telescopes. By locating the observatory in space, it can capture X-rays from distant celestial objects without interference, providing clearer and more detailed images of the universe. Additionally, operating in space allows Chandra to observe continuously without the interruptions caused by Earth's day-night cycle.

It is going to replace the Hubble Space Telescope in the year 2018. It will study the edges of the universe, where the light from the creation of the Universe is still in transit to the Earth. So what JWST will do is to look at the past, billions of years ago, when the Universe was only a few hundred million years old. This would help us understand more about the evolution of the Universe.

no, the moon has a synchronous rotation, which means that it rotates so that the same side is always facing earth

also, the moon rotates and revolves at the same time every 27.3 days, while Earth revolves around the Sun yearly and rotates or spins on its axis every 24 hours, this causes day and night to occur.

The phase difference between the reflected and refracted waves is π radians (180 degrees). This means that the two waves are in opposite phases when they interact with the glass plate.

aren't you filling out a worksheet that your teacher gave you and that's why you asked? cuz im too

There are also disadvantages of having telescopes in space 1 is that they are expensive to run and maintain each launch can cost millions of dollars and building the telescope can cost many million as well. Transmitting the information to earth can take longer then telescopes on the ground and can require more power.

The reflecting pool was built as part of the design of the National Mall in Washington, D.C. to provide a serene and visually appealing element that would reflect the monuments and memorials surrounding it, creating a sense of grandeur and symmetry. It also serves as a place for visitors to relax and enjoy the scenery.

There are a number of differences. First, they are in different orbits; the Hubble is higher than the ISS. The ISS is a lot bigger. Probably the most important difference is that the Hubble has a big telescope but no people, while the ISS has people but no big telescope.

you can use the telescope at the beacon (top of light house) or you can use it in two missions: case of the missing puffles and avalanche rescue. You can also use binoculars at the cove. Have Fun!

HST uses no fuel at all - it was designed to be an orbital repair satellite from the beginning, and the Shuttle that performs each Servicing Mission boosts it back into a higher orbit after they're done working on it. All power comes from the huge twin solar panels on each side. Since no more missions are planned (don't hold your breath - HST is NASA's largest PR cash cow), HST will eventually decay until it burns up in the atmosphere.

Sending spacecraft far enough into space to see Earth in the past would be technically challenging due to the vast distances involved and limitations of our current technology. Additionally, the time delay in receiving images from such a distant location would make real-time observation of Earth's past impossible. Instead, scientists rely on methods such as studying light from distant objects and cosmic background radiation to understand the history and evolution of the universe, including Earth.

Telescopes on Earth can detect a wide range of electromagnetic radiation, including radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays. Different telescopes are designed to detect specific wavelengths within this range, allowing astronomers to study various objects in the universe.

Isaac Newton is credited with building the first practical reflecting telescope in 1668. This telescope used a curved mirror to gather and focus light, unlike traditional refracting telescopes which used lenses.

Both reflecting and refracting telescopes are designed to gather and focus light to create images of distant objects in space. Reflecting telescopes use mirrors to reflect and concentrate light, while refracting telescopes use lenses to refract and focus light.
