The Square Kilometre Array ( SKA ) is a radio telescope in development in Australia and South Africa which will have a total collecting area of approximately one square kilometre. [ 1 ] It will operate over a wide range of frequencies and its size will make it 50 times more sensitive than any other radio instrument.

Upsilon Andromedae d is an extrasolar planet orbiting the Sun -like star Upsilon Andromedae A . Its discovery in April 1999 by Geoffrey Marcy and R. Paul Butler made Upsilon Andromedae the first star (other than the pulsar PSR 1257+12 and the Sun) to be known to host a multiple-planet planetary system .

Everyone loves a good "they said it couldn't be done" story. From a man on the moon to a personal computer in every home, the nostalgic in each of us loves to reflect about how, throughout history, individuals have run up against the status quo, defied the odds, and achieved something inspirational for society at-large.
5G
5G ( 5th generation mobile networks or 5th generation wireless systems ) is a term used in some research papers and projects to denote the next major phase of mobile telecommunications standards beyond the current 4G / IMT-Advanced standards. 5G does not describe any particular specification in any official document published by any telecommunication standardization body.
Konstantin Tsiolkovsky
Konstantin Eduardovich Tsiolkovsky [ 1 ] (17 September [ O.S. 5 September] 1857 – 19 September 1935) was a Russian and Soviet rocket scientist and pioneer of the astronautic theory . Along with his followers, the German Hermann Oberth and the American Robert H. Goddard , he is considered to be one of the founding fathers of rocketry and astronautics . [ 2 ] His works later inspired leading Soviet rocket engineers such as Sergey Korolyov and Valentin Glushko and contributed to the success of the Soviet space program .
The visible spectrum is the portion of the electromagnetic spectrum that is visible to (can be detected by) the human eye . Electromagnetic radiation in this range of wavelengths is called visible light or simply light . A typical human eye will respond to wavelengths from about 390 to 700 nm . [ 1 ] In terms of frequency, this corresponds to a band in the vicinity of 430–790 THz .

Luminous efficacy
Luminous efficacy is a measure of how well a light source produces visible light. It is the ratio of luminous flux to power .July 26, 2011 — Scientists at Rensselaer Polytechnic Institute have found that when just 10 percent of the population holds an unshakable belief, their belief will always be adopted by the majority of the society.
