Telescopes

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.

The prefix "tele" in telescope comes from the Greek word "téle," which means far off or distant. In the context of telescope, it suggests that the device is used for viewing distant objects, such as stars and planets.

No, a bird looking at a mirror is an example of light being reflected, not refracted. When light hits the mirror, it bounces off in a different direction but does not change mediums. Refraction is when light passes through different mediums and changes direction.

Aristotle did not invent the telescope; he lived roughly 2000 years before the telescope was invented.

? Beats me. My star chart is pretty empty at 15h13m58.55s and 0 11 03.98 arc degrees, at least out to magnitude 6.35. Most likely they may be exhibiting a deep sky thingie from the Hubble.

NASA named its X-ray telescope after Indian astrophysicist Subrahmanyan Chandrasekhar, in recognition of his groundbreaking work on the evolution and structure of stars. The Chandra X-ray Observatory was launched in 1999 and continues to provide valuable insights into the high-energy universe.

"EQ" on a telescope lens typically refers to the type of mount the telescope sits on. EQ stands for equatorial mount, which is a type of mount that can be aligned with the Earth's axis to track celestial objects as they move across the sky.

A Cassegrain telescope is designed with mirrors along the inside of its body tube. Light enters the tube and first reflects off a concave primary mirror at the back of the tube, then reflects off a smaller convex secondary mirror before exiting the tube. This design allows for a more compact telescope with a long focal length.

Astronomers have several reasons to send telescopes into space, including:

* The atmosphere makes stars look blurry. the simple answer is the atmosphere. The layers of air in the atmosphere may seem clear but contribute to a fuzzy picture in space. To avoid this they send telescopes into space where nothing is in between the telescope and the observed object.

One reason for sending telescopes into space is so that people can get a better look at the stars the second reason for this is so that scientist can discover more about stars.

* The atmosphere completely blocks some kinds of light -- in particular, ultraviolet and far-infrared light. On earth, spectrometers using this kind of light tell us a lot about local materials. To get the same information about stars and planets, we need to put the spectrometer outside the veil of the atmosphere.

People who are not astronomers have other reasons to send telescopes into space, including

* Telescopes on "weather satellites" and "spy satellites" pointed at earth can get photos and accurate maps of places and weather that are extremely difficult to get in any other way.

Galileo used to telescope to map out the stars. To be honest, the telescope was very important because he noticed that Jupiter actually had moons... this got Galileo into trouble because it proved that the earth wasn't the center of the universe (went against the church)...... he studied the crescents on Venus and such. It provided him a scientific tool to go beyond the normal humans eye sight. If you want to know more im sure wiki has plenty of pages on Galilo. :)

None this time... did this from my memory. :)

The reflecting telescope, invented by Sir Isaac Newton, allowed for sharper and brighter images of celestial objects compared to the refracting telescope. This telescope played a crucial role in advancements in astronomy and led to discoveries such as the rings of Saturn, the moons of Jupiter, and the spiral structure of galaxies.

refracting telescopes use lenses instead of mirrors.

1. chromatic aberration: when light passes through a lens it is focused at different points. Blue focuses closer to lens and red farther creating a smeared image.

2. Some light is absorbed by lenses.

3. Lenses are heavy and can only be supported by the edge.

4. Lenses must have to optically acceptable surfaces whereas a mirror only needs one.
