XO-1b
XO-1b is an extrasolar planet approximately 536 light-years away from Earth. The planet XO-1b is named Negoiu. The name was selected in the NameExoWorlds campaign by Romania, during the 100th anniversary of the IAU. Negoiu is the second highest peak in Romania. In 2006, the XO Project, an international team of professional and amateur astronomers, discovered a Jupiter-sized planet, later named XO-1b, orbiting a Sun-like star. The team, led by Peter R. McCullough of the Space Telescope Science Institute in Baltimore, had four amateur astronomers hailing from North America and Europe. An independent confirmation of the planet was made by the Wide Angle Search for Planets project later that same year. The XO Project team employed the relatively inexpensive XO Telescope, made from commercial equipment, to search for extrasolar planets. This telescope is on the Hawaiian Island of Maui. From September 2003 to September 2005, the XO Telescope detected tens of thousands of bright s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corona Borealis (constellation)
Corona Borealis is a small constellation in the Northern Celestial Hemisphere. It is one of the 48 constellations listed by the 2nd-century astronomer Ptolemy, and remains one of the 88 modern constellations. Its brightest stars form a semicircular arc. Its Latin name, inspired by its shape, means "northern crown". In classical mythology Corona Borealis generally represented the crown given by the god Dionysus to the Cretan princess Ariadne and set by her in the heavens. Other cultures likened the pattern to a circle of elders, an eagle's nest, a bear's den, or even a smokehole. Ptolemy also listed a southern counterpart, Corona Australis, with a similar pattern. The brightest star is the magnitude 2.2 Alpha Coronae Borealis. The yellow supergiant R Coronae Borealis is the prototype of a rare class of giant stars—the R Coronae Borealis variables—that are extremely hydrogen deficient, and thought to result from the merger of two white dwarfs. T Coronae Boreal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
XO Project
The XO Project is an international team of amateur and professional astronomers tasked with identifying extrasolar planets. They are led by Peter R. McCullough of the Space Telescope Science Institute. It is primarily funded by NASA's Origins Program and the Director's Discretionary Fund of the Space Telescope Science Institute. Duties Preliminary identification of possible star candidates starts at the Haleakala telescope in Hawaii by a team of professional astronomers. Once they identify a star that dims slightly from time to time, the information is forwarded to a team of amateur astronomers who then investigate for additional evidence suggesting this dimming is caused by a transiting planet. Once enough data is collected, it is forwarded to the University of Texas McDonald Observatory to confirm the presence of a transiting planet by a second team of professional astronomers. Equipment McCullough and his team employed a relatively inexpensive telescope called an XO Telescope, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
XO Telescope
The XO Telescope is an astronomical telescope located on the 3,054 m (10,000 foot) summit of Haleakala on Maui, Hawaii. It consists of two 200-millimeter telephoto camera lenses, and resembles binoculars in shape. It is used by the XO Project to detect extrasolar planets using the transit method. It is similar to the TrES survey telescope. The construction of the one-of-a-kind telescope cost $60,000 for the hardware, and much more than that for the associated software. Planets discovered The ''XO telescope'' has discovered six objects so far, five are hot Jupiter planets and one, XO-3b, may be a brown dwarf. All were discovered using the transit method. ''Light green rows indicate that the planet orbits one of the stars in a binary star system.''

List Of Transiting Extrasolar Planets
This is the list of 232 transiting extrasolar planets sorted by orbital periods. All the transiting planets have true masses, radii and most have known inclinations. Radius is determined by how much the star dims during the transit and inclination is determined from Rossiter–McLaughlin effect. True mass is determined by the minimum mass determined from radial velocity observations divided by the sine of inclination. The first known planet to be discovered with the transit method was OGLE-TR-56b. The first planetary transit observed (by already known exoplanet) was caused by HD 209458 b. The most massive transiting exoplanet is KELT-1b which masses 27.23 MJ (making it a brown dwarf) while the least massive is Kepler-42d which masses less than 0.003 MJ or 0.9 M🜨. The largest exoplanet known is HAT-P-32b which is 2.037 RJ. The smallest exoplanet known is also Kepler-42d which is 0.051 RJ or 0.57 R🜨. The densest transiting exoplanet known is COROT-3b, which has density of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Harlan J
John Marshall Harlan (June 1, 1833 – October 14, 1911) was an American lawyer and politician who served as an associate justice of the U.S. Supreme Court from 1877 until his death in 1911. He is often called "The Great Dissenter" due to his many dissents in cases that restricted civil liberties, including the ''Civil Rights Cases'', ''Plessy v. Ferguson'', and '' Giles v. Harris''. Many of Harlan's views expressed in his notable dissents would become the official view of the Supreme Court starting from the 1950s Warren Court and onward. His grandson John Marshall Harlan II was also a Supreme Court justice. Born into a prominent, slave-holding family near Danville, Kentucky, Harlan experienced a quick rise to political prominence. When the American Civil War broke out, Harlan strongly supported the Union and recruited the 10th Kentucky Infantry. Despite his opposition to the Emancipation Proclamation, he served in the war until 1863, when he won election as Attorney General of ...

Hubble Space Telescope
The Hubble Space Telescope (often referred to as HST or Hubble) is a space telescope that was launched into low Earth orbit in 1990 and remains in operation. It was not the first space telescope, but it is one of the largest and most versatile, renowned both as a vital research tool and as a public relations boon for astronomy. The Hubble telescope is named after astronomer Edwin Hubble and is one of NASA's Great Observatories. The Space Telescope Science Institute (STScI) selects Hubble's targets and processes the resulting data, while the Goddard Space Flight Center (GSFC) controls the spacecraft. Hubble features a mirror, and its five main instruments observe in the ultraviolet, visible, and near-infrared regions of the electromagnetic spectrum. Hubble's orbit outside the distortion of Earth's atmosphere allows it to capture extremely high-resolution images with substantially lower background light than ground-based telescopes. It has recorded some of the most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
