 " महानुभाव पंथ "


महानुभाव पंथ  महाराष्ट्र राज्यातील एक जुना पंथ आहे श्री चक्रधर स्वामी हे महानुभाव पंथांचे संस्थापक होत. श्री चक्रधर स्वामी यांनी रचलेल्या लीळाचरित्र या आद्य ग्रंथातील उपदेश केशिराज बास यांनी इ.स. १२८५ च्या सुमारास संकलित केला.
केशिराज बास यांना केसोबास नावानेही ओळखले जाते. हे महानुभव पंथातील ज्येष्ठ ग्रंथकार, व संस्कृत पंडित होत. महानुभाव पंथाचे दुसरे आचार्य नागदेवाचार्य हे यांचे पट्टशिष्य. यांच्या सूचनेवरून केशिराज बास यांनी मराठी भाषेत ग्रंथ रचना केली. दृष्टांत पाठात अनेक लोककथा गुंफल्या आहेत.
The Wow! signal was a strong narrowband radio signal detected by Dr. Jerry R. Ehman on August 15, 1977, while working on a SETI project at the Big Ear radio telescope of The Ohio State University. The signal bore expected hallmarks of potential non-terrestrial and non-solar system origin. It lasted for the full 72-second duration that Big Ear observed it, but has not been detected again. Much attention has been focused on it in the media when talking about SETI results.
Amazed at how closely the signal matched the expected signature of an interstellar signal in the antenna used, Ehman circled the signal on the computer printout and wrote the comment "Wow!" on its side. This comment became the name of the signal.


The circled alphanumeric code 6EQUJ5 describes the intensity variation of the signal. A space denotes an intensity between 0 and 1, the numbers 1 to 9 denote the correspondingly numbered intensities (from 1.000 to 10.000), and intensities of 10.0 and above are denoted by a letter ('A' corresponds to intensities between 10.0 and 11.0, 'B' to 11.0 to 12.0, etc.). The value 'U' (an intensity between 30.0 and 31.0) was the highest detected by the telescope, on a linear scale it was over 30 times louder than normal deep space. The intensity in this case is the unitless signal-to-noise ratio, where noise was averaged for that band over the previous few minutes.
Two different values for its frequency have been given: 1420.356 MHz (J. D. Kraus) and 1420.4556 MHz (J. R. Ehman). The frequency 1420 is significant for SETI searchers because, it is reasoned, hydrogen is the most common element in the universe, and hydrogen resonates at about 1420 MHz, thus extraterrestrials might use that frequency on which to transmit a strong signal.[1] The frequency of the Wow! signal matches very closely with the hydrogen line, which is at 1420.40575177 MHz. The bandwidth of the signal is less than 10 kHz (each column on the printout corresponds to a 10 kHz-wide channel; the signal is only present in one column).

Save Earth

"Save Earth"
 Because Earth is only planet in Solar 
 System which has life...
As far as we know, Earth is the only planet which has life. There may be life on other planets within our Solar System, but we may not have found them yet. The only possible planets within our Solar System is Mars. There may well be life on some of the moons of other planets, and these include Europa and Titan. but until they are explored it will stay a possibility,

Outside of our Solar System, there are bountiful possibilities, but we cannot be certain due to limitations in technology.
