Telescopes

Some disadvantages of telescopes include limited field of view, susceptibility to atmospheric conditions such as turbulence and light pollution, and the need for regular maintenance and calibration to ensure optimal performance. Additionally, high-quality telescopes can be expensive and may require specialized expertise to operate effectively.

Saturn is the second largest planet behind jupiter! The sizes from smallest to largest are Pluto and Charon (which is actually a dwarf planet) Mercury Mars Venus Earth Neptune Uranus Saturn Jupiter the answer is D. Venus, Neptune, Saturn

The sputnik series of satellites were unmanned. Sputnik II carried an expendable dog.

The first microscopes were called Light Microscopes, and they work by passing visible light through whatever specimen is being observed and then through the glass lenses of the microscope. The lenses refract the light and magnify the image of the specimen as it is projected into the eye. Modern microscopes use beams of electrons instead of light. There are two main type of Electron Microscopes: Scanning Electron Microscope (SEM) and Transmission Electron Microscope (TEM). SEMs are used to observe the surface of a specimen, and TEMs are used to observe the internal structure of specimens.

A telescope is an instrument with curved mirrors and lenses to make distant objects appear closer.

The Greek word "teleskopos".

Based on chemical spectography, which is the maximum science we can use presently, we have "seen" approximately 1.25% of what "we think" are the range parameters of the universe. The farthest we've seen through spectography (much farther than visual or radiotelescopy) is about 600 billion light years away. Do the math - too many zero's for me.

Prior to being launched into space on 23 Jul 1999 on STS-93, the Chandra X-Ray Observatory (CXO) was given an expected lifetime of 5 years. In September 2001 NASA extended the CXO's lifetime to 10 years "based on the observatory's outstanding results."

Physically the observatory could last for much longer. A study performed at the Chandra X-ray Center indicated that the CXO could last at least 15 years.

Because current technology cannot significantly improve upon the resolving power of Chandra's mirrors, it's unlikely that another x-ray observatory will be launched before 2015. So we'll probably get to see just how long Chandra can last.

Large telescopes are often housed in observatories located in remote and high-altitude areas to minimize light pollution and atmospheric interference. These locations provide clearer skies and better visibility for astronomical observations.

The Hubble telescope was a basic reflector telescope with a 94.5 ft mirror. The Hubble collects light though its open end, the primary mirror reflects the light to a secondary mirror that then reflects the light through a hole in the primary mirror to a focal point of the instruments or eyes of the Hubble.

The biggest telescopes on Earth typically operate in the optical and infrared parts of the electromagnetic spectrum. These telescopes are used to study a wide range of celestial objects, from planets and stars to galaxies and quasars.

Semen generally contains sperm cells, and it is the sperm cells in the semen that cause pregnancy. However, if the man has had a successful vasectomy or had his testes removed, his semen will not contain sperm cells.

The cost of a reflecting telescope can vary greatly depending on the size, brand, and quality of the telescope. Entry-level reflecting telescopes can start at around $200, while more advanced models can cost several thousand dollars or more.

Duh.. simply because during the night time if you look inside of a telescope and look out of it you'll see the big and Lil dipper but you'll also see Venus glowing because it isn't night time yet on Venus because it takes 225 days on earth for Venus to become Unable to see so you can't see Venus glow every 225 days on earth

Once the Space Telescope project had been given the go-ahead, work on the program was divided among many institutions.

Marshall Space Flight Center (MSFC) was given responsibility for the design, development, and construction of the telescope, while theGoddard Space Flight Center was given overall control of the scientific instruments and ground-control center for the mission. MSFC commissioned the optics company Perkin-Elmer to design and build the Optical Telescope Assembly (OTA) and Fine Guidance Sensors for the space telescope. Lockheed was commissioned to construct the spacecraft in which the telescope would be housed.

Perkin-Elmer was commissioned to build the optical components of the Hubble Space Telescope. The construction of the main mirror was begun in 1979 and polishing completed in 1981 in Danbury Connecticut.

A reflector telescope collects light with a mirror. The mirror is located at the back of the telescope and reflects the incoming light to a focal point where it is then collected by an eyepiece for viewing.

In 1781, William Herschel discovered a planet which he named 'Georgian Star', after King George. It was popularly known as 'Herschel', but was later named Uranus. He later discovered two of its' moons, Titania and Oberon.

Telescopes that collect electromagnetic radiation in shorter wavelengths, such as ultraviolet or X-rays, need to be placed in dry areas or outside the atmosphere because water vapor and other gases in the atmosphere can absorb or scatter such high-energy radiation, affecting the observations. Placing these telescopes in dry areas or above the atmosphere helps ensure that they can collect unimpeded data in these wavelengths.

Isaac Newton is credited with designing the first practical reflecting telescope in the 17th century, known as the Newtonian telescope. By using a curved mirror to reflect and focus light, Newton's design offered advantages over traditional refracting telescopes of the time.

No, they cannot. Only a little over 50% of the moon's surface can be observed from earth, and observations must be made over a period of about 15 years in order to observe the maximum amount of surface.

To turn around a centre point is to rotate.

Yes they do. They have 4 arms. They have antennae. They have big black egg-shaped eyeballs. They have, as their mouth, a little thick tube with a suction cup at the end to suck grease from a sausage. They have 2 pointy ears.

Jocelyn Bell Burnell is a prominent astrophysicist from Northern Ireland. She is best known for her discovery of pulsars, which are rapidly rotating neutron stars that emit beams of electromagnetic radiation. Despite her groundbreaking discovery, she faced significant gender discrimination in the field of astrophysics.

The eccentricity of Halley's comet is approximately 0.967, which is quite high compared to other solar system objects. This high eccentricity means that its orbit is very elongated, taking it from the outer solar system to the inner solar system and back every 76 years.
