Questions & Answers
Question : What was the significance of galileo's "new astronomy" and his telescope , beyond science?
in other words how was he significant in a way that does not have to do with science. real answers only please
Answer:
Galileo did not invent the telescope, so it is not "his telescope." His use of the telescope to look at and study planets continued a scientific paradigm shift within the cultural paradigm shift of the Renaissance, high Middle Ages, and the Protestant Reformation which started in 1517. Copernicus started the scientific paradigm shift when he published shortly before his death. Galileo's planetary studies and publications were the final step in the scientific paradigm shift."...Copernicus' Secret: How the Scientific Revolution Began - Google Books Result by Jack Repcheck - 2008 - Biography & Autobiography - 256 pagesThe rupture that eventually became the Protestant Reformation officially started in the autumn of 1517, when Ferber was still a canon and Copernicus was ...books.google.com/books?isbn=0743289528..."

Question : earth space science problems on microscopes and telescopes?
Explain the two problems that we have with using optical telescopes from inside the atmosphere.What kinds of limitations are there to using a manned mission to explore space?
Answer:
1) Earth Based Optical Telescopes1.1) Bad weather you can't see through clouds and rain.1.2) Atmospheric distortion. The Atmosphere distorts star light falling on the earth. 2.0)Manned Space Mission.2.1) Heavy Human Payloads are costly and don't add value - Extra breathable atmosphere, Water, Food, toilet, and sleeping facilities are need to support human life. All of that room could be used for automated experiments that don't require all of that care.2.2) Human frailty and value on life: Humans are more susceptible to the extremes of space. One CME striking a manned mission to mars could completely kill everyone on board and may destroy the spacecraft. Where as an unmanned mission would only loose the space craft. No loss of life, no grieving widows, no bereaved orphans - less cost to humanity.

Question : I need help with a science question regarding telescopes?
How long an exposure would a photographer need to photograph star trails that are complete circles? Why?
Answer:
24 hours and it could only be done near the winter solstice at the north or south pole, because that is the only place it would be dark for 24 hours . Any place else or at any other time, Daylight would happen before you were done (Who comes up with questions like this?)

Question : how do you use an edu science telescope?
I have a 70 edu science star gazer from toys r us and i cant focus on a certain star that i think is a planet. Ihave tried using the biggest lense and it still wont focus so i dont know if we are puttung the lense in right. How do you use the largest lense!!!!
Answer:
I concur with trying it in the daytime, and if it won't come to a sharp focus, return it since that crosses the line from a flawed telescope to an outright faulty one.Bear in mind that planets will still look small through a telescope even if it's working properly. Don't expect them to fill the field of view. Venus, Mars, Jupiter, and Saturn should however be clearly tiny disks, as contrasted to stars which will look like points.

Question : GRADE 8 SCIENCE HELP! Microscopes and Telescopes!?
Compare the structure and use of a classroom microscope with the structure and use of an astronomical refracting telescope.
Answer:
Telescopes are focused to see objects far away while Microscopes are focused to seem items close up. The focal range of the object changes depending on whether it is very close to the lens or far away. The closer the object, the longer the focal point is from the lense to allow you to focus on it with the eyepiece lense. Lens power can be calculated by dividing the length of the primary lens (or mirror) and dividing it by the focal length of the eyepiece. This will give you your magnification power. If you divide the focal length by the lens diameter, you get your "f" number (like F-Stops on a camera). The higher the F number the darker the image will be. Conversely, the larger the primary lens, the more light gathering power the lens has. This is why professional telescopes are very very big. They aren't built that way for magnification power, but for light gathering ability. The higher the light gathering ability, the more stars a big telescope will see.Microscopes are the same basic principal, but pointed downward with it's own light source, so it doesn't need a large primary lens.

Question : What are the different types of land based telescopes and space telescopes?
I ma doing this for science coursework. I ened it by the the end of this lessonwhat are the different types of land based telescopes?what are the different type sof space telescopes?please help!
Answer:
When we observe, we usually observe a portion of the electromagnetic spectrum.Ground Based Telescopes -- Are easy to build, but hindered by the fact that much of the EM spectrum is blocked by the earth's atmosphere:Radio Telescopes -- Observe Radio Waves. These are the "big dishes out in the desert"Submilimeter Telescopes -- Observe just above radio waves.Optical Telescopes -- These are what live in domes. There are two main types: Reflecting Telescopes -- Use giant mirrors. These are the only "large" modern telescopes, and are being built with single mirrors as large as 8.6 meters and multiple mirrors as large as 30+m. Refracting Telescopes -- These use lenses (like a spyglass or binoculars). These have fallen out of favor, as they are hard to build and introduce problems in the incoming light. The largest in the world in only about 40 inches.Unlike ground based telescopes, space based telescopes can observe all the bands, including those that don't penetrate the earth's atmosphere.Space Based Telescopes:Radio -- None currently deployedInfrared -- Detects "heat" from distant objectOptical -- Takes pictures. Example: Hubble. These are all reflectors, there are no (major) space based refractors.Ultraviolet -- Just above the optical band.X-Ray/Gamma-Ray -- These are super high energy particles from stars. They can only be observed from space, as our atmosphere blocks them.Finally, stretching the definition of telescope, there are super giant tanks of extremely pure water (or other compounds) buried miles under the earth's surface. These can be used to detect non-electromagnetic radiation (neutrinos). These aren't telescopes, per se, but they can detect the outpouring of neutrinos from fusion in the hearts of stars.

Question : i need help with a science question regarding telescopes?
The star Sirius is 4.3 light years from Earth. Determine the distance to Sirius in kilometres and and in astronomical units.
Answer:
Um... Sirius is 8.1 light years away - Alpha Centauri is 4.3 light years away...So, lets figure this out. Light travels about 298,000 km/sec. How far will it go in a year?There are 60 seconds X 60 minutes X 24 Hours X 365.25 days in a year, or 31,557,600 seconds per year. Multiply this by the speed of light per second, you get:298,000 km/sec X 31,557,600 secs = 9,404,164,800,000km / year - this is a light year.Multiply this by the number of light years "Sirius" is away: 4.3 x 9,404,164,800,000 = 40,437,908,640,000 km awayFor astonomical units, that's the distance from Earth to the sun; that's about 157,000,000 km.Divide the distance of sirius by 1 AU: 40,437,908,640,000 / 157,000,000 = 257,566.3 AUs.
