Q. Who is Karl Jansky and why are his contributions important to space exploration?
Karl Jansky, in full Karl Guthe Jansky, (born October 22, 1905, Norman, Oklahoma, U.S.—died February 14, 1950, Red Bank, New Jersey), American engineer whose discovery of radio waves from an extraterrestrial source inaugurated the development of radio astronomy, a new science that from the mid-20th century greatly …

Q. What did Grote Reber discover?
He was 90. Mr. Reber was an engineering student in 1931 when Karl Jansky of Bell Telephone Laboratories, using a large antenna system, made his famous discovery of cosmic radio waves emanating from beyond the solar system.
Q. What was the first radio telescope called?
The first radio telescope, built in 1937 by Grote Reber of Wheaton, Ill., U.S., was a steerable paraboloid–i.e., a device with a parabolically shaped reflector, dubbed the “dish,” that focuses the incoming radio waves onto a small pickup antenna, or “feed.” The radio telescope at Jodrell Bank, Cheshire, Eng., has a …
Q. How far can a radio telescope see?
We can also use them to transmit and reflect radio light off of planetary bodies in our solar system. These specially-designed telescopes observe the longest wavelengths of light, ranging from 1 millimeter to over 10 meters long.
Q. What is the farthest planet we can see with a telescope?
Saturn, the most distant, bright naked-eye planet, lies 950 million miles from Earth at mid-month.
Q. What planet is the furthest away?
Neptune

Q. What eyepiece is best for Jupiter?
In most cases you need two to three eyepieces of different powers, say a 25mm, 15mm and a 10mm and a barlow lens. A 2X barlow will double the power of an eyepiece practically turning a 25mm into a 12.5mm. If you have any filters, an 80A Blue seems to work fairly decent on Jupiter.
Q. How much magnification do you need to see Mars?
It usually requires an instrument of at least 115 to 130 mm and a strong magnification (up to 150x) for the first surface details to be visible. However, it is important to not underestimate what a 4″ scope can do. Many planetary observers use 4″ refractors very effectively to observe minute planetary detail.
