Mary R. Calvert
Mary Ross Calvert (June 20, 1884 – June 25, 1974) was an American astronomical computer and astrophotographer. She started as her uncle Edward Emerson Barnard's assistant and ended publishing his (and their) work that cataloged over 300 dark objects (dark nebulae) — primarily those that extinguish the most starlight reaching the earth lie between the bulk (inward local sector, central bulge, and other sectors of the Milky Way) thus between the Local Arm (Orion Arm) and the Sagittarius Arm. She went on to publish other photographic works on astronomy. Early life Calvert was born in Nashville, Tennessee, on June 20, 1884, to Alice Rosamond (Phillips) and Ebenezer Calvert (1850–1924). She was the eldest of their four daughters. Her father's elder sister Rhoda had married the astronomer Edward Emerson Barnard, and out of respect, her parents had called her sister Alice Barnard Calvert. Her father and his younger brother Peter Ross Calvert (1855–1931) ran Calvert Photogra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Great Rift (astronomy)
In astronomy, the Great Rift (sometimes called the Dark Rift or less commonly the Dark River) is a dust lane, dark band caused by interstellar clouds of cosmic dust that significantly obscure (extinction (astronomy), extinguish) the Galactic Center, center and most radial sectors of the Milky Way galaxy from Earth's perspective. In dark, clear night sky, night skies, the rift appears as clear as the bright galactic bulge, bulge of stars around the Galactic Center does to the naked eye or binoculars. The rift is largely between the Solar System (which is close to the inner edge of the Orion Arm) and the next arm, inward, the Sagittarius Arm. The clouds are an obstruction to millions of the galaxy's stars detected at visible spectrum, visible wavelengths, which compose a bright hazy band appearing angular diameter, 30° wide and arching through the night sky. The clouds within our radial sector of the galaxy span about from Earth. The clouds are estimated to contain about 1 millio ...

Barnard's Star
Barnard's Star is a red dwarf about six light-years from Earth in the constellation of Ophiuchus. It is the fourth-nearest-known individual star to the Sun after the three components of the Alpha Centauri system, and the closest star in the northern celestial hemisphere. Its stellar mass is about 14% of the Sun's. Despite its proximity, the star has a dim apparent magnitude of +9.5 and is invisible to the unaided eye; it is much brighter in the infrared than in visible light. The star is named after E. E. Barnard, an American astronomer who in 1916 measured its proper motion as 10.3 arcseconds per year relative to the Sun, the highest known for any star. The star had previously appeared on Harvard University photographic plates in 1888 and 1890. Barnard's Star is among the most studied red dwarfs because of its proximity and favorable location for observation near the celestial equator. Historically, research on Barnard's Star has focused on measuring its stellar characte ... [...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 ...
