Exoplanets Discovered In 1998
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.

Gizmodo
''Gizmodo'' ( ) is a design, technology, science and science fiction website. It was originally launched as part of the Gawker Media network run by Nick Denton, and runs on the Kinja platform. ''Gizmodo'' also includes the subsite ''io9'', which focuses on science fiction and futurism. ''Gizmodo'' is now part of G/O Media, owned by private equity firm Great Hill Partners. History The blog, launched in 2002, was originally edited by Peter Rojas, who was later recruited by Weblogs, Inc. to launch their similar technology blog, ''Engadget''. By mid-2004, ''Gizmodo'' and ''Gawker'' together were bringing in revenue of approximately $6,500 per month. Gizmodo then launched in other locations: *In 2005, VNU and Gawker Media formed an alliance to republish ''Gizmodo'' across Europe, with VNU translating the content into French, German, Dutch, Spanish, Italian and Portuguese, and adding local European-interest material. *In 2006, ''Gizmodo Japan'' was launched by Mediagene, with add ...

National Geographic Society
The National Geographic Society (NGS), headquartered in Washington, D.C., United States, is one of the largest non-profit scientific and educational organizations in the world. Founded in 1888, its interests include geography, archaeology, and natural science, the promotion of environmental and historical conservation, and the study of world culture and history. The National Geographic Society's logo is a yellow portrait frame—rectangular in shape—which appears on the margins surrounding the front covers of its magazines and as its television channel logo. Through National Geographic Partners (a joint venture with The Walt Disney Company), the Society operates the magazine, TV channels, a website, worldwide events, and other media operations.

Extragalactic Planet
An extragalactic planet, also known as an extragalactic exoplanet or an extroplanet, is a star-bound planet or rogue planet located outside of the Milky Way Galaxy. Due to the immense distances to such worlds, they would be very hard to detect directly. However, indirect evidence suggests that such planets exist. Nonetheless, the most distant known planets are SWEEPS-11 and SWEEPS-04, located in Sagittarius, approximately 27,710 light-years from the Sun, while the Milky Way is between 100,000 and 180,000 light years in diameter. This means that even galactic planets located farther than that distance have not been detected. Candidate extragalactic planets Twin Quasar-related planet A microlensing event in the Twin Quasar gravitational lensing system was observed in 1996, by R. E. Schild, in the "A" lobe of the lensed quasar. It is predicted that a 3-Earth-mass planet in the lensing galaxy, YGKOW G1, caused the event. This was the first extragalactic planet candidate announced. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
