Vytautas Straižys
Vytautas Straižys (20 August 1936 – 19 December 2021) was a Lithuanian astronomer. In 1963–65 he and his collaborators created and developed the Vilnius photometric system, a seven-color intermediate band system, optimized for photometric stellar classification. In 1996 he was elected a Corresponding Member of the Lithuanian Academy of Sciences. Straižys was an editor of the journal ''Baltic Astronomy''. He spent a lot of time working at the Molėtai Astronomical Observatory. Asteroid 68730 Straizys in 2002 was named after him. Early life and professional history Straižys was born in Utena on 20 August 1936. In 1959, he graduated from Vilnius University in astrophysics. In 1959–62, he was a graduate student of the Institute of Physics and Mathematics of the Lithuanian Academy of Sciences. In 1962–67, he was a scientific researcher at the same institute. From 1967 to 1990, he headed the Astrophysical Department of the Institute of Physics, Vilnius. In 1990–2003, he wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Utena
Utena () is a city in north-east Lithuania. It is the administrative center of Utena district and Utena County. Utena is one of the oldest settlements of Lithuania. The name of the city is most probably derived from a hydronym. The name of the settlement has been known since 1261. Utena is an industrial city. It is known for its clothing, food and beverage factories. In recent years, however, streets, public squares and large areas of the parks in the city were reconstructed and Utena is now more attractive for recreation and tourism. In 2007, Utena won a Silver Award in category B (towns with a population between 10,001 and 50,000) of the International Awards for Liveable Communities, held in London. The anniversary of Utena City had been held each year on the last weekend of September. Since 2013 the anniversary has been held on the first weekend of September to take advantage of better weather conditions. Geography Utena is located in northeastern Lithuania. The city cove ...

Stars
A star is an astronomical object comprising a luminous spheroid of plasma held together by its gravity. The nearest star to Earth is the Sun. Many other stars are visible to the naked eye at night, but their immense distances from Earth make them appear as fixed points of light. The most prominent stars have been categorised into constellations and asterisms, and many of the brightest stars have proper names. Astronomers have assembled star catalogues that identify the known stars and provide standardized stellar designations. The observable universe contains an estimated to stars. Only about 4,000 of these stars are visible to the naked eye, all within the Milky Way galaxy. A star's life begins with the gravitational collapse of a gaseous nebula of material composed primarily of hydrogen, along with helium and trace amounts of heavier elements. Its total mass is the main factor determining its evolution and eventual fate. A star shines for most of its active life du ...

Asteroid
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 ...

American Astronomical Society
The American Astronomical Society (AAS, sometimes spoken as "double-A-S") is an American society of professional astronomers and other interested individuals, headquartered in Washington, DC. The primary objective of the AAS is to promote the advancement of astronomy and closely related branches of science, while the secondary purpose includes enhancing astronomy education and providing a political voice for its members through lobbying and grassroots activities. Its current mission is to enhance and share humanity's scientific understanding of the universe as a diverse and inclusive astronomical community. History The society was founded in 1899 through the efforts of George Ellery Hale. The constitution of the group was written by Hale, George Comstock, Edward Morley, Simon Newcomb and Edward Charles Pickering. These men, plus four others, were the first Executive Council of the society; Newcomb was the first president. The initial membership was 114. The AAS name of the so ...

Institute For Space Observations
An institute is an organisational body created for a certain purpose. They are often research organisations ( research institutes) created to do research on specific topics, or can also be a professional body. In some countries, institutes can be part of a university or other institutions of higher education, either as a group of departments or an autonomous educational institution without a traditional university status such as a "university institute" (see Institute of Technology). In some countries, such as South Korea and India, private schools are sometimes referred to as institutes, and in Spain, secondary schools are referred to as institutes. Historically, in some countries institutes were educational units imparting vocational training and often incorporating libraries, also known as mechanics' institutes. The word "institute" comes from a Latin word ''institutum'' meaning "facility" or "habit"; from ''instituere'' meaning "build", "create", "raise" or "educate". ...
