Rotten Egg Nebula
The Calabash Nebula, also known as the Rotten Egg Nebula or by its technical name OH 231.84 +4.22, is a protoplanetary nebula (PPN) 1.4 light years (13 Pm) long and located some 5,000 light years (47 Em) from Earth in the constellation Puppis. The name "Calabash Nebula" was first proposed in 1989 in an early paper on its expected nebular dynamics, based on the nebula's appearance. The Calabash is almost certainly a member of the open cluster Messier 46, as it has the same distance, radial velocity, and proper motion. The central star is QX Puppis, a binary composed of a very cool mira variable and an A-type main-sequence star. Description Violent gas collisions that produced supersonic shock fronts in a dying star are seen in a detailed image from NASA's Hubble Space Telescope. The object is sometimes called the Rotten Egg Nebula as it contains a relatively large amount of sulphur. The densest parts of the nebula are composed of material ejected recently by the central st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Duck, Duck, Goose
Duck, Duck, Goose (also called Duck, Duck, Gray Duck or Daisy in the Dell or Quail, Quail, Quarry sometimes in New Jersey and New England) is a traditional children's game often first learned in preschool or kindergarten. The game may be later adapted on the playground for early elementary students. The object of this game is to walk in a circle, tapping on each player's head until one is finally chosen; the chosen player must then chase the picker to avoid becoming the next picker. Basic concept A group of players sits in a circle, facing inward, while another player, who is "it", walks around tapping or pointing to each player in turn, calling each a "duck" until finally calling one a "goose", which designates the chosen player as the chaser. The chaser (goose) then stands and tries to tag the chasee (it), while the chasee tries to return to and sit where the chaser had been sitting before. If the chasee (it) succeeds, the chaser (goose) becomes the chasee and the process b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrogen Sulfide
Hydrogen sulfide is a chemical compound with the formula . It is a colorless chalcogen-hydride gas, and is poisonous, corrosive, and flammable, with trace amounts in ambient atmosphere having a characteristic foul odor of rotten eggs. The underground mine gas term for foul-smelling hydrogen sulfide-rich gas mixtures is ''stinkdamp''. Swedish chemist Carl Wilhelm Scheele is credited with having discovered the chemical composition of purified hydrogen sulfide in 1777. The British English spelling of this compound is hydrogen sulphide, a spelling no longer recommended by the Royal Society of Chemistry or the International Union of Pure and Applied Chemistry. Hydrogen sulfide is toxic to humans and most other animals by inhibiting cellular respiration in a manner similar to hydrogen cyanide. When it is inhaled or it or its salts are ingested in high amounts, damage to organs occurs rapidly with symptoms ranging from breathing difficulties to convulsions and death. Despite this, the ...
