Valentin D. Ivanov
Valentin D. Ivanov ( bg, Валентин Д. Иванов) is a Bulgarian astronomer working in the European Southern Observatory, mainly at the Paranal site. Among his primary research areas are the dynamics of star clusters, formation of stars, brown dwarfs, and exoplanets around such objects. Valentin Ivanov and Ray Jayawardhana are two of the pioneers of the investigation of the planemos. They discovered the first double planemo Oph 162225-240515. This discovery came just before the debate about the 2006 planet definition, and posed the problem about the distinction between planets and brown dwarfs. Background Valentin D. Ivanov was born in the town of Bourgas, Bulgaria in 1967. He obtained his master's degree in physics and astronomy at the University of Sofia in 1992. He earned a PhD degree at the University of Arizona, Tucson, Arizona, U.S. in 2001. He became a fellow at the European Southern Observatory, on La Silla Observatory, La Silla and Cerro Paranal. In 2003-2014 he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astronomer
An astronomer is a scientist in the field of astronomy who focuses their studies on a specific question or field outside the scope of Earth. They observe astronomical objects such as stars, planets, natural satellite, moons, comets and galaxy, galaxies – in either observational astronomy, observational (by analyzing the data) or theoretical astronomy. Examples of topics or fields astronomers study include planetary science, Sun, solar astronomy, the Star formation, origin or stellar evolution, evolution of stars, or the galaxy formation and evolution, formation of galaxies. A related but distinct subject is physical cosmology, which studies the Universe as a whole. Types Astronomers usually fall under either of two main types: observational astronomy, observational and theoretical astronomy, theoretical. Observational astronomers make direct observations of Astronomical object, celestial objects and analyze the data. In contrast, theoretical astronomers create and investigate C ...

La Silla Observatory
La Silla Observatory is an astronomy, astronomical observatory in Chile with three telescopes built and operated by the European Southern Observatory (ESO). Several other telescopes are located at the site and are partly maintained by ESO. The observatory is one of the largest in the Southern Hemisphere and was the first in Chile to be used by ESO. The La Silla telescopes and instruments are located 150 km northeast of La Serena, Chile, La Serena at the outskirts of the Chilean Atacama Desert, one of the driest and most remote areas of the world. Like other observatories in this geographical area, La Silla is located far from sources of light pollution and, like the Paranal Observatory, home to the Very Large Telescope, it has one of the darkest night skies on the Earth. History Following the decision in 1963 to approve Chile as the site for the ESO observatory, scouting parties were sent to various locations to assess their suitability. The site that was decided upon was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bulgarian Language
Bulgarian (, ; bg, label=none, български, bălgarski, ) is an Eastern South Slavic language spoken in Southeastern Europe, primarily in Bulgaria. It is the language of the Bulgarians. Along with the closely related Macedonian language (collectively forming the East South Slavic languages), it is a member of the Balkan sprachbund and South Slavic dialect continuum of the Indo-European language family. The two languages have several characteristics that set them apart from all other Slavic languages, including the elimination of case declension, the development of a suffixed definite article, and the lack of a verb infinitive. They retain and have further developed the Proto-Slavic verb system (albeit analytically). One such major development is the innovation of evidential verb forms to encode for the source of information: witnessed, inferred, or reported. It is the official language of Bulgaria, and since 2007 has been among the official languages of the Eur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Science Fiction
Science fiction (sometimes shortened to Sci-Fi or SF) is a genre of speculative fiction which typically deals with imaginative and futuristic concepts such as advanced science and technology, space exploration, time travel, parallel universes, extraterrestrial life, sentient artificial intelligence, cybernetics, certain forms of immortality (like mind uploading), and the singularity. Science fiction predicted several existing inventions, such as the atomic bomb, robots, and borazon, whose names entirely match their fictional predecessors. In addition, science fiction might serve as an outlet to facilitate future scientific and technological innovations. Science fiction can trace its roots to ancient mythology. It is also related to fantasy, horror, and superhero fiction and contains many subgenres. Its exact definition has long been disputed among authors, critics, scholars, and readers. Science fiction, in literature, film, television, and other media, has beco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kiril Dobrev
The male name Kiril (or Кирил or Кирилл) is a common first name in the Orthodox Slavic world, in particular in Bulgaria, North Macedonia, and Russia. It is also well known in Greece but in different forms like Kyriakos. (Note that in modern Russian the spelling Кирил is considered to be a mistake, the correct spelling is Кирилл.) Kiril has several variant forms: Cyril, Cyrill, Kirill, Kirillos, Kiryl (Belarusian), Kyril, Cyryl (Polish), Kyrill, Kyrylo (Ukrainian) and a diminutive Kiro (common in the Balkan Sprachbund). Saint Cyril of Jerusalem was a 4th-century bishop and a Doctor of the Church. Saint Cyril of Alexandria was a 5th-century theologian. Another Saint Cyril, known as Kiril, was a 9th-century translator and a Byzantine missionary to the Slavs. He, together with his brother Methodius, created an alphabet called the Glagolitic alphabet to serve the needs of the Slavic world, translating the Bible into the Church Slavic language. Later, their stu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bulgaria
Bulgaria (; bg, България, Bǎlgariya), officially the Republic of Bulgaria,, ) is a country in Southeast Europe. It is situated on the eastern flank of the Balkans, and is bordered by Romania to the north, Serbia and North Macedonia to the west, Greece and Turkey to the south, and the Black Sea to the east. Bulgaria covers a territory of , and is the sixteenth-largest country in Europe. Sofia is the nation's capital and largest city; other major cities are Plovdiv, Varna and Burgas. One of the earliest societies in the lands of modern-day Bulgaria was the Neolithic Karanovo culture, which dates back to 6,500 BC. In the 6th to 3rd century BC the region was a battleground for ancient Thracians, Persians, Celts and Macedonians; stability came when the Roman Empire conquered the region in AD 45. After the Roman state splintered, tribal invasions in the region resumed. Around the 6th century, these territories were settled by the early Slavs. The Bulgars, led by Asp ...

VISTA (telescope)
The VISTA (Visible and Infrared Survey Telescope for Astronomy) is a wide-field reflecting telescope with a 4.1 metre mirror, located at the Paranal Observatory in Chile. It is operated by the European Southern Observatory and started science operations in December 2009. VISTA was conceived and developed by a consortium of universities in the United Kingdom led by Queen Mary University of London and became an in-kind contribution to ESO as part of the UK's accession agreement, with the subscription paid by the UK Science and Technology Facilities Council (STFC). VISTA is a survey telescope working at infrared wavelengths, and is by far the largest telescope in the world dedicated to surveying the sky at near-infrared wavelengths. The telescope has only one instrument: VIRCAM, the Vista InfraRed CAMera. This is a 3-tonne camera containing 16 special detectors sensitive to infrared light, with a combined total of 67 million pixels. A second-generation instrument called 4MOST, a 240 ...

Very Large Telescope
The Very Large Telescope (VLT) is a telescope facility operated by the European Southern Observatory on Cerro Paranal in the Atacama Desert of northern Chile. It consists of four individual telescopes, each with a primary mirror 8.2 m across, which are generally used separately but can be used together to achieve very high angular resolution. The four separate optical telescopes are known as ''Antu'', ''Kueyen'', ''Melipal'', and ''Yepun'', which are all words for astronomical objects in the Mapuche language. The telescopes form an array complemented by four movable Auxiliary Telescopes (ATs) of 1.8 m aperture. The VLT operates at visible light, visible and infrared wavelengths. Each individual telescope can detect objects roughly four billion times fainter than can be detected with the naked eye, and when all the telescopes are combined, the facility can achieve an angular resolution of about 0.002 arcsecond. In single telescope mode of operation angular resolution is ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
