=JUPITER'S GIANT RED SPOT=

==**One of the most populars description of Jupiter,the fifth and the biggest planet of our solar system is that has a big red spot that is a persistent anticyclonic storm that is located 22° south of the equator and is more bigger than our planet earth. Some mathematical scientists says that is a permanent because it is know that it have existed in 1881 and others scientist says that it has existed in 1665 and dosen't stops. The great red spot rotates with a period about 6 earth days. Storms such as this are common within the turbulent atmospheres of gas giants. Jupiter also has white ovals and brown ovals, which are lesser unnamed storms. In 2000, an atmospheric feature formed in the southern hemisphere that is similar in appearance to the Great Red Spot, but smaller in size.

=Project Gemini=  On May 25, 1961 President John F. Kennedy announced that the U.S. should commit to "landing a man on the moon and return him safely to Earth before the end of the decade", which created the Apollo program. The Gemini Program was designed to test the technologies needed for the Apollo program, whose missions were much more complex.

It began with the Gemini 3 on March 21, 1965 and ended with the Gemini 12 Nov 11, 1966. Edward White, who later died in the crash of Apollo 1, made with the Gemini 4 on June 3, 1965 the first space walk by an American. On December 15, 1965 the Gemini 6 and 7, manned by two astronauts each, made their first rendezvous approaching vessels up to 1.8 m. The flight of Gemini 7 lasted two weeks, while it was felt necessary for the Apollo missions. On March 16, 1966 the Gemini 8 spacecraft manned by Neil Armstrong and David Scott, who later would be the first man to step on the moon, his ship docked at 8 Agena rocket preparing the docking maneuver between the lunar module and the Apollo spacecraft.   The Gemini spacecraft was an improved version of the Mercury and had originally received the name of Mercury Mark II. The improvements were made both in size and in control capacity. The Gemini had a weight of more than 3628.72 kilograms, double the Mercury. But on the other hand, despite having an increase in the space cockpit of the 50% it should be occupied by two astronauts instead of one as in the Mercury missions. Another difference from the Gemini spacecraft is they had ejection seats in replacement of the tower to rescue the Mercury, also had more storage space for extended missions, which require fuel cells to replace batteries for the generation electric power.  __Unlike the Mercury, which could only change its orientation in space, the Gemini had to use the capabilities of orbital maneuver for a reunion with another ship.__ The Gemini had to move forward, backward, and even change the direction orbit. Due to the complexity of the maneuvers reunion, the ships required the presence of two astronauts and the use of the first computers on board to perform complicated calculations that would help establish a successful reunion.

In astronomy and cosmology, [|dark matter] is hypothetical matter that does not interact with the electromagnetic force, but whose presence can be inferred from gravitational effects on visible matter. According to present observations of structures larger than galaxies, as well as Big Bang cosmology, dark matter and dark energy account for the vast majority of the mass in the observable universe. The observed phenomena which imply the presence of dark matter include the rotational speeds of galaxies, orbital velocities of galaxies in clusters, gravitational lensing of background objects by galaxy clusters such as the Bullet cluster, and the temperature distribution of hot gas in galaxies and clusters of galaxies. Dark matter also plays a central role in structure formation and galaxy evolution, and has measurable effects on the anisotropy of the cosmic microwave background. All these lines of evidence suggest that galaxies, clusters of galaxies, and the universe as a whole contain far more matter than that which interacts with electromagnetic radiation: the remainder is called the "dark matter component." The dark matter component has much more mass than the "visible" component of the universe.At present, the density of ordinary baryons and radiation in the universe is estimated to be equivalent to about one hydrogen atom per cubic meter of space. Only about 4% of the total energy density in the universe (as inferred from gravitational effects) can be seen directly. About 22% is thought to be composed of dark matter. The remaining 74% is thought to consist of dark energy, an even stranger component, distributed diffusely in space. Some hard-to-detect baryonic matter is believed to make a contribution to dark matter but would constitute only a small portion.Determining the nature of this missing mass is one of the most important problems in modern cosmology and particle physics. It has been noted that the names "dark matter" and "dark energy" serve mainly as expressions of human ignorance, much as the marking of early maps with "terra incognita." media type="custom" key="2689281" [|Types of Dark Matter] Hot dark matter is composed of particles that have zero or near-zero mass (the neutrinos are a prime example). The Special Theory of Relativity requires that massless particles move at the speed of light and that nearly massless particles move at nearly the speed of light. Thus, such very low mass particles must move at very high velocities and thus form (by the kinetic theory of gases) very hot gases. On the other hand, cold dark matter is composed of objects sufficiently massive that they move at sub-relativistic velocities. They thus form much colder gases. The difference between cold dark matter and hot dark matter is significant in the formation of structure, because the high velocities of hot dark matter cause it to wipe out structure on small scales. <span style="FONT-SIZE: 140%; COLOR: #53fa0f; FONT-FAMILY: 'Comic Sans MS', cursive; BACKGROUND-COLOR: #000000"> <span style="COLOR: #000000; FONT-FAMILY: 'Comic Sans MS', cursive; BACKGROUND-COLOR: #ffffff">media type="custom" key="2689293"

Archaeopteryx is the most primitive bird known. Archaeopteryx lived in the late jurassic period around 155-150 million yers ago in what is now southern germany.The archaeopteryx fossil is considered one of the most important ever discovered. The Archaeopteryx by many scientist to be the link between birds and dinosaurs. it had teeth and claws, but it also had feathers and wings. Each wing had two separate fingers on the leading wing edges that were equipped with sharp claws. The biggest differences, are in the skull. The lack of a breast bone suggest that the archaeopteryx was not a strong flier, butflight muscles might have attached to the bird's thick, boomerang shaped wishbone. The large wings and the long tail ,however, suggest that it was stable and maneuverable in the air. The shapeof the wings is similar to the birds through trees and brush. =====
