RT-70
There are three radio telescopes designated RT-70, all in countries that were once part of the former Soviet Union, all with similar specifications: 70m dishes and an operating range of 5–300 GHz. The Yevpatoria telescope has also been used as a radar telescope in observations of space debris and asteroids. With their 70m antenna diameter, they are among the largest radio telescopes in the world. They are: * the Yevpatoria RT-70 radio telescope at the former soviet Center for Deep Space Communications or West Center for Deep Space Communications, Yevpatoria, Crimea ( Russian-annexed, internationally recognised as part of Ukraine) * the Galenki RT-70 radio telescope at the East Center for Deep Space Communications, Galenki (Ussuriysk), Russia * the Suffa RT-70 radio telescope at the Suffa Radio Observatory on the Suffa plateau, Uzbekistan In 2008, RT-70 was used to beam 501 messages at the exoplanet Gliese 581c, in hopes of making contact with extraterrestrial intellig ...

Radio Telescopes
A radio telescope is a specialized antenna and radio receiver used to detect radio waves from astronomical radio sources in the sky. Radio telescopes are the main observing instrument used in radio astronomy, which studies the radio frequency portion of the electromagnetic spectrum emitted by astronomical objects, just as optical telescopes are the main observing instrument used in traditional optical astronomy which studies the light wave portion of the spectrum coming from astronomical objects. Unlike optical telescopes, radio telescopes can be used in the daytime as well as at night. Since astronomical radio sources such as planets, stars, nebulas and galaxies are very far away, the radio waves coming from them are extremely weak, so radio telescopes require very large antennas to collect enough radio energy to study them, and extremely sensitive receiving equipment. Radio telescopes are typically large parabolic ("dish") antennas similar to those employed in tracking and c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Yevpatoria RT-70 Radio Telescope
The Yevpatoria RT-70 radio telescope (P-2500, RT-70) is an RT-70 radio telescope and planetary radar at the Center for Deep Space Communications, Yevpatoria, Crimea. In the scientific literature is often called Evpatoria Planetary Radar (EPR). History With its 70-meter antenna diameter, it is among the largest single dish radio telescopes in the world. It has an advantage in comparison with other large radio telescopes in the fact that the complex includes powerful transmitters that allow active space experiments. Powerful electromagnetic beams can be accurately targeted and the signals received can be analyzed. For this reason, the Yevpatoria RT-70 radio telescope is one of only two in the world that are able to transmit messages to extraterrestrial civilizations, i.e. the multiple Cosmic Calls, Teen Age Messages or A Message from Earth (AMFE). Radio telescopes are highly sensitive detectors of signals from outer space. The radio telescope is depicted on Russia's commemorat ...

Yevpatoria
Yevpatoria ( uk, Євпаторія, Yevpatoriia; russian: Евпатория, Yevpatoriya; crh, , , gr, Ευπατορία) is a city of regional significance in Western Crimea, north of Kalamita Bay. Yevpatoria serves as the administrative center of Yevpatoria Municipality, one of the districts (''raions'') into which Crimea is divided. It had a population of History Greek settlement The first recorded settlement in the area, called ''Kerkinitis'' (), was built by Greek colonists around 500 BCE. Along with the rest of the Crimea, Kerkinitis formed part of the dominions of King Mithridates VI Eupator ( BCE), from whose nickname, ''Eupator'' "of noble father" the city's modern name derives. Khanate period From roughly the 7th through the 10th centuries, Yevpatoria was a Khazar settlement; its name in Khazar language was probably ''Güzliev'' (literally "beautiful house"). It was later subject to the Cumans ( Kipchaks), the Mongols and the Crimean Khanate. During t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gliese 581c
Gliese 581c (Gl 581c or GJ 581c) is a planet orbiting within the Gliese 581 system. It is the second planet discovered in the system and the third in order from the star. With a mass at least 5.5 times that of the Earth, it is classified as a super-Earth (a category of planets with masses greater than Earth's up to ten Earth masses). Gliese 581c gained interest from astronomers because it was reported to be the first potentially Earth-like planet in the habitable zone of its star, with a temperature right for liquid water on its surface, and, by extension, potentially capable of supporting extremophile forms of Earth-like life. However, further research casts doubt upon the planet's habitability. It is tidally locked (always presents the same face to the object it is orbiting) so if life had a chance to emerge, the best hope of survival would be in the " terminator zone". In astronomical terms, the Gliese 581 system is relatively close to Earth, at in the direction of the cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radar Telescope
Radar astronomy is a technique of observing nearby astronomical objects by reflecting radio waves or microwaves off target objects and analyzing their reflections. Radar astronomy differs from ''radio astronomy'' in that the latter is a passive observation (i.e., receiving only) and the former an active one (transmitting and receiving). Radar systems have been conducted for six decades applied to a wide range of Solar System studies. The radar transmission may either be pulsed or continuous. The strength of the radar return signal is proportional to the inverse fourth-power of the distance. Upgraded facilities, increased transceiver power, and improved apparatus have increased observational opportunities. Radar techniques provide information unavailable by other means, such as testing general relativity by observing Mercury and providing a refined value for the astronomical unit. Radar images provide information about the shapes and surface properties of solid bodies, which cann ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asteroids
An asteroid is a minor planet of the inner Solar System. Sizes and shapes of asteroids vary significantly, ranging from 1-meter rocks to a dwarf planet almost 1000 km in diameter; they are rocky, metallic or icy bodies with no atmosphere. Of the roughly one million known asteroids the greatest number are located between the orbits of Mars and Jupiter, approximately 2 to 4 AU from the Sun, in the main asteroid belt. Asteroids are generally classified to be of three types: C-type, M-type, and S-type. These were named after and are generally identified with carbonaceous, metallic, and silicaceous compositions, respectively. The size of asteroids varies greatly; the largest, Ceres, is almost across and qualifies as a dwarf planet. The total mass of all the asteroids combined is only 3% that of Earth's Moon. The majority of main belt asteroids follow slightly elliptical, stable orbits, revolving in the same direction as the Earth and taking from three to six years to comple ...

Exoplanet
An exoplanet or extrasolar planet is a planet outside the Solar System. The first possible evidence of an exoplanet was noted in 1917 but was not recognized as such. The first confirmation of detection occurred in 1992. A different planet, initially detected in 1988, was confirmed in 2003. There are many methods of detecting exoplanets. Transit photometry and Doppler spectroscopy have found the most, but these methods suffer from a clear observational bias favoring the detection of planets near the star; thus, 85% of the exoplanets detected are inside the tidal locking zone. In several cases, multiple planets have been observed around a star. About 1 in 5 Sun-like starsFor the purpose of this 1 in 5 statistic, "Sun-like" means G-type star. Data for Sun-like stars was not available so this statistic is an extrapolation from data about K-type stars. have an "Earth-sized"For the purpose of this 1 in 5 statistic, Earth-sized means 1–2 Earth radii. planet in the habitable zone. ...
