Telescopes

The most important part of a telescope is the telescope tube. Other parts are the viewfinder or optical finderscope, eyepiece, focuser, reflecting mirrors, refracting lenses, and the mount assembly.

The second telescope was invented by Galileo Galilei in the early 17th century. He improved upon the design of the original telescope invented by Hans Lippershey, enhancing its magnification and clarity. Galileo used his telescope to make groundbreaking astronomical discoveries, including observations of the moons of Jupiter and the phases of Venus.

light waves do not require a medium to travel through, unlike water and sound waves which both need a medium (water and air, respectively). Light waves are electromagnetic in nature and can travel through a vacuum. They have different wave properties such as wavelength, frequency, and speed compared to water and sound waves.

The concept of the universe as we know it today was not named by any specific individual. The word "universe" comes from the Latin word "universum," meaning everything that exists, and has been used for centuries to describe the totality of all matter, energy, space, and time.

Optical microscopes use visible light to magnify objects, providing lower resolution images compared to electron microscopes which use beams of electrons to achieve higher magnification and resolution. Electron microscopes are able to see smaller objects in more detail due to the shorter wavelength of electrons compared to visible light.

Because both planets orbit the sun, the distance varies, since at some times both will be on the same side of the sun, but at other times, on opposite sides.

When Jupiter and Earth are closest, Jupiter is 390,682,810 miles (628,743,036 km) from Earth. The Earth is 93,000,000 miles (149,668,992 km) from the Sun. Jupiter is 483,682,810 miles (778,412,028 km) from the Sun. At our most distant, Jupiter is 576,682,810 miles (928,081,020 km) from the Earth, when the two planets are on opposite sides of the Sun. Measured in Astronomical Units (AU), the distance between Earth and Jupiter varies from 4.2 AU to 6.2 AU. An Astronomical Unit is approximately 93,000,000 miles (149,668,992 km), or the mean distance from the Earth to the Sun. Therefore, the distance between the Earth and Jupiter can be anywhere between slightly over four times or six times the distance from the Earth to the Sun.

The calculations are very close, but approximate, and also depend upon the slightly varying mass of the Sun, which has an effect on orbital distances.

It's about 370 million miles

The distance from Jupiter to Earth varies every year due to their elliptical orbits. At their closest point, the distance between the two planets is 365 million miles.

Distance from earth to sun is 93 million miles

How far is Earth from the Sun

Distance from Jupiter from sun is 484 million miles

How far is Jupiter from the Sun

Jupiter from sun - Earth from sun = Jupiter from earth

484 - 93 = Jupiter is 391 miles from earth

Please note, these numbers are rounded and in miles. The exact number may be slightly different due to rounding error. Also, because both earth and Jupiter have an elliptical orbit around earth, this number can vary from time to time. 391 is just the average distance.

Saturn's rings are made up of ice, rock, and dust particles that vary in size. These particles are thought to be remnants of comets, asteroids, or moons that broke apart in Saturn's gravitational field. The rings are likely kept in place by the gravitational pull of Saturn's moons and the planet itself.

The azimuth of Aquila, which is a constellation in the northern hemisphere, varies depending on the time and location. It is best viewed in the summer months, and its azimuth will change throughout the night as the Earth rotates. It typically ranges from around 265° to 295° in the evening sky.

The telescope was invented by Hans Lippershey, a spectacle maker from the Netherlands, in 1608. However, another spectacle maker and astronomer, Galileo Galilei, was the first to use the telescope for astronomical purposes in 1609.

Well, it auctually depends on the day that it is setting from, and how the day will be tomorrow. SO if it is going to be in the 90's the next day, and it was the 90's today, then it will go.... # A blue sky # Then the sun will start to lower and then a orange/red will come in # Then the sun will be about half way and then a purple/red/blue will show from behind the sun # As the sun is done and out of view, if the weather was nice and will be nice, then you should see a pink sky. I feel as if I cant stress it enough, all of the ways that a sunset will be depends on the weather AND location.

The reflecting telescope was invented by English scientist Sir Isaac Newton in 1668. He designed this type of telescope to overcome some of the limitations of the refracting telescopes that were used at the time. The reflecting telescope uses mirrors rather than lenses to gather and focus light, allowing for larger and more powerful telescopes to be built.

Isaac newton developed the laws of gravity when an apple fell out of a tree and hit him on the head.

Astronomers typically look through telescopes at the stars to study celestial objects such as planets, stars, galaxies, and other phenomena in the universe. They use telescopes to gather data and make observations that help expand our knowledge of the cosmos.

The moon is in pretty good shape, overall. It has very little pollution on it. Just a few artifacts, mostly of keen historical interest.

The moon is, of course, spherical. It is shaped much like a ball. When I gaze upon its surface, the evening of January 29th, 2009, I notice it in the western sky, preceding Venus. It is a fairly thin crescent, and combined with Venus looks a bit like the flag of Turkey--the star and crescent.

The temperature of the moon during the night is -233 Celsius and 123 Celsius during the day. It is because the Moon doesnÕt have an atmosphere to block the Sun rayÕs that could help to trap heat at night.

The answer is obviously C.

It's not hiding from the sunlight that's the problem, but the (mostly blue) light scattered by the air.

Your idea would work on the moon,

and it has been tried on Earth, with sad results.

If you are a junior astronomer then forget getting a telescope unless you are willing to get a very good one costing several hundreds of pounds or dollars. Cheap 'toy' telescopes are next to useless, as they claim to have great magnification, but the image is usually very poor and grainy and impossible to see properly because the optics and light gathering power are usually pretty poor. Also, the mounting of toy telescopes are usually flimsy and result in a great deal of shake. Often a good mount is as espensive as the telescope itself. A good pair of binoculars with a tripod to reduce shake should be perfectly adequate for seeing the craters on the moon, Jupiter and its moons, Venus, and large star clusters and nebulae like the Pleiades. The rings of Saturn may be too small for a small pair of binoculars, and so in this case a decent telescope is better. If you are keen on getting a telescope rather than binoculars then there are some excellent sites that will sell you one and give advice. www.telescopehouse.com a a superb UK site where you can get excellent advice and real machines that are not toys. If you are living in the UK, avoid toy 'scopes from Argos, catalogues or camera shops - they are next to useless, poorly made, shake all over the place and their optics are dreadful - and they are expensive for a pile of junk. If you wish to take up the hobby seriously, then a reflector telescope is better with a mirror of 6 inches or more, (or 8 if you live in a city - to compensate for light pollution) with a really good Equatorial mount to avoid shake. If you can afford a motor drive too to compensate for the earth's motion then that would be an advantage. To get a variety of magnifications you will need several eyepieces of different focal lengths. Choose only reputable makes like Celestron or Meade whose optics are excellent.

One last point - NEVER use a telescope to look at the sun with or without a 'safety' filter. That is the surest way of you ending up permanently blind. Dark filters may cut down the light but most of the sun's heat usually passes straight through, is focussed just like light onto your retina, ad, whilst you think everthing is Ok it merrily burns a hole in your retina just like catching a piece of paper on fire using a magnifying glass. You have been warned!

NRAO operates a few sites, including the Very Large Array (VLA) in New Mexico, the Atacama Large Millimeter Array (ALMA) in Chile, the Very Long Baseline Array (VLBA) across the United States, and the Green Bank Telescope (GBT) in West Virginia.

Terminator technology in agriculture is the use of genetic engineering to create varieties that produce seeds that are sterile and will not produce a crop the following year.

The light that we see from Canopus today actually left the star over 310 years ago. Canopus is located approximately 310 light-years away from Earth, so the light we see now started its journey towards us over three centuries ago.

Microscopes and telescopes are similar in that they both use lenses to magnify and enhance our ability to see objects that are too small or too far away to be seen with the naked eye. They rely on principles of optics to manipulate light in order to produce clearer and enlarged images.

Space junk, in others words is trash floating around our Earth caught in a circular orbit. Space junk has caused problems and I will happily list a few for the answer. For one, if it is biggest enough sometimes it will fall back to the Earth and unlike most things, not burn up in the atmosphere and come crashing to Earth which itself poses dangers. Another is moving space junk can become problems to space stations. Damage, severe or little can be caused by junk ramming into the station. More problems it poses by space shuttles can, sometimes, hit space junk which you can figure is a problem.

More or less Space Junk in other words is pollution in space.

Voyager 1 is roughly 15 billion kilometers from the Sun (about 105 times the distance from the Sun to the Earth). Both of the Voyager craft have now traveled far beyond the orbit of Pluto, and have recently "officially" left the solar system (crossed the heliopause, the boundary where the solar wind meets the interstellar magnetic field).

The planet Mars can appear reddish and star-like in the night sky. Its reddish hue is due to iron oxide, or rust, on its surface. You can see Mars without a telescope when it is visible in the night sky.
