Sea

A sea is a large body of salt water that is surrounded in whole or in part by land. More broadly, "the sea" is the interconnected system of Earth's salty, oceanic waters—considered as one global ocean or as several principal oceanic divisions. The sea moderates Earth's climate and has important roles in the water cycle, carbon cycle, and nitrogen cycle. Although the sea has been travelled and explored since prehistory, the modern scientific study of the sea—oceanography—dates broadly to the British Challenger expedition of the 1870s. The sea is conventionally divided into up to five large oceanic sections—including the IHO's four named oceans (the Atlantic, Pacific, Indian, and Arctic) and the Southern Ocean; smaller, second-order sections, such as the Mediterranean, are known as seas.

Owing to the present state of continental drift, the Northern Hemisphere is now fairly equally divided between land and sea (a ratio of about 2:3) but the South is overwhelmingly oceanic (1:4.7).Salinity in the open ocean is generally in a narrow band around 3.5% by mass, although this can vary in more landlocked waters, near the mouths of large rivers, or at great depths. About 85% of the solids in the open sea are sodium chloride. Deep-sea currents are produced by differences in salinity and temperature. Surface currents are formed by the friction of waves produced by the wind and by tides, the changes in local sea level produced by the gravity of the Moon and Sun. The direction of all of these is governed by surface and submarine land masses and by the rotation of the Earth (the Coriolis effect).

Sea (astronomy)

The Sea or the Water is an area of the sky in which many water-related, and few land-related, constellations occur. This may be because the Sun passed through this part of the sky during the rainy season.

Most of these constellations are named by Ptolemy:

Sometimes included are the ship Argo and Crater the Water Cup.

Some water-themed constellations are newer, so are not in this region. They include Hydrus, the lesser water snake; Volans, the flying fish; and Dorado, the swordfish.

Osiris (genus)

The cleptoparasitic bee genus Osiris is a rare group of apid bees from the Neotropics (Mexico through Argentina), that lay their eggs in the nests of bees in the related tribe Tapinotaspidini, such as Paratetrapedia. Most of the known species are pale yellowish, smooth and shining, and very wasp-like in appearance.

Females in this tribe are unusual in having the last metasomal sternite elongated to form a sheath for the sting, which is remarkably long.

HD 209458 b

HD 209458 b (sometimes unofficially called Osiris) is an exoplanet that orbits the solar analog HD 209458 in the constellation Pegasus, some 150 light-years from the Solar System. The radius of the planet's orbit is 7 million kilometres, about 0.047 astronomical units, or one eighth the radius of Mercury's orbit. This small radius results in a year that is 3.5 Earth days long and an estimated surface temperature of about 1,000 °C (about 1,800 °F). Its mass is 220 times that of Earth (0.69 Jupiter masses) and its volume is some 2.5 times greater than that of Jupiter. The high mass and great volume of HD 209458 b indicate that it is a gas giant.

HD 209458 b represents a number of milestones in extraplanetary research. It was the first of many categories:

Osiris (DC Comics)

Osiris is the name of three fictional characters published by DC Comics. The first appeared in 1994 as a foil for the Justice League. The second appeared under the Vertigo Comics imprint in a spin-off of The Sandman in 2002. The third debuted in the pages of Teen Titans and 52 in 2006.

Publication history

The first Osiris appeared in Justice League International vol. 2 #62 (March 1994) and was created by Gerard Jones and Chuck Wojtkiewicz. He appeared monthly in that title and its companions, Justice League America and Justice League Task Force until August 1994. The second Osiris appeared in the one-shot Sandman Presents: The Thessaliad #1 (March 2002) and was created by Bill Willingham and Shawn McManus. The third Osiris was first depicted in Teen Titans vol. 3 #38 (September 2006) and was created by Geoff Johns, Greg Rucka, Grant Morrison and Mark Waid. He appeared extensively in the weekly series 52 published in 2006 and 2007.
