2001
2001 was dominated by September 11 attacks against the United States by Al-Qaeda, which killed 2,977 people and instigated the global war on terror. The United States led a multi-national coalition in an invasion of Afghanistan after the Taliban government did not extradite Al-Qaeda leader Osama bin Laden. Internal conflicts, political or otherwise, caused shifts in leadership in multiple countries, which included the assassination of Laurent-Désiré Kabila in the Democratic Republic of the Congo, the Second EDSA Revolution in the Philippines, the massacre of the royal family by the crown prince in Nepal, and civil unrest in Argentina. Other notable political events were an escalation in the Israeli–Palestinian conflict, the storming of the Indonesian parliament, the Hainan Island incident between China and the United States, an insurgency in Macedonia, and a terrorist attack on the Parliament of India that began the 2001–2002 India–Pakistan standoff.

Kuiper Belt
The Kuiper belt () is a circumstellar disc in the outer Solar System, extending from the orbit of Neptune at 30 astronomical units (AU) to approximately 50 AU from the Sun. It is similar to the asteroid belt, but is far larger—20 times as wide and 20–200 times as massive. Like the asteroid belt, it consists mainly of small bodies or remnants from when the Solar System formed. While many asteroids are composed primarily of rock and metal, most Kuiper belt objects are composed largely of frozen volatiles (termed "ices"), such as methane, ammonia, and water. The Kuiper belt is home to most of the objects that astronomers generally accept as dwarf planets: Orcus, Pluto, Haumea, Quaoar, and Makemake. Some of the Solar System's moons, such as Neptune's Triton and Saturn's Phoebe, may have originated in the region. The Kuiper belt was named after Dutch astronomer Gerard Kuiper, although he did not predict its existence. In 1992, minor planet (15760) ...

Second Intifada
The Second Intifada ( ar, الانتفاضة الثانية, ; he, האינתיפאדה השנייה, ), also known as the Al-Aqsa Intifada ( ar, انتفاضة الأقصى, label=none, '), was a major Palestinian uprising against Israel. The general triggers for the unrest are speculated to have been centred around the failure of the 2000 Camp David Summit, which was expected to reach a final agreement on the Israeli–Palestinian peace process in July 2000. Outbreaks of violence began in September 2000, after Ariel Sharon, then the Israeli opposition leader, made a provocative visit to the Temple Mount in Jerusalem; The visit itself was peaceful, but, as anticipated, sparked protests and riots that Israeli police put down with rubber bullets and tear gas. High numbers of casualties were caused among civilians as well as combatants. Israeli forces engaged in gunfire, targeted killings, and tank and aerial attacks, while the Palestinians engaged in suicide bombings, g ...

September 11 Attacks
The September 11 attacks, commonly known as 9/11, were four coordinated suicide terrorist attacks carried out by al-Qaeda against the United States on Tuesday, September 11, 2001. That morning, nineteen terrorists hijacked four commercial airliners scheduled to travel from the Northeastern United States to California. The hijackers crashed the first two planes into the Twin Towers of the World Trade Center in New York City, and the third plane into the Pentagon (the headquarters of the United States military) in Arlington County, Virginia. The fourth plane was intended to hit a federal government building in Washington, D.C., but crashed in a field following a passenger revolt. The attacks killed nearly 3,000 people and instigated the war on terror. The first impact was that of American Airlines Flight 11. It was crashed into the North Tower of the World Trade Center complex in Lower Manhattan at 8:46 a.m. Seventeen minutes later, at 9:03, the World Trade Cen ...

Deorbit Of Mir
The Russian space station ''Mir'' ended its mission on 23 March 2001, when it was brought out of its orbit, entered the atmosphere and was destroyed. Major components ranged from about 5 to 15 years in age, and included the Mir Core Module, Kvant-1, Kvant-2, Kristall, Spektr, Priroda, and Docking Module. Although Russia was optimistic about ''Mirs future, the country's commitments to the International Space Station programme left no funding to support ''Mir''. The deorbit was carried out in three stages. The first stage was waiting for atmospheric drag to decay the orbit to an average of . This began with the docking of Progress M1-5. The second stage was the transfer of the station into a orbit. This was achieved with two burns of the Progress M1-5's control engines at 00:32 UTC and 02:01 UTC on 23 March 2001. After a two-orbit pause, the third and final stage of ''Mirs deorbit began with the firing of Progress M1-5's control engines and main engine at 05:08 UTC, la ...

28978 Ixion
28978 Ixion (, provisional designation ) is a large trans-Neptunian object and a possible dwarf planet. It is located in the Kuiper belt, a region of icy objects orbiting beyond Neptune in the outer Solar System. Ixion is classified as a plutino, a dynamical class of objects in a 2:3 orbital resonance with Neptune. It was discovered in May 2001 by astronomers of the Deep Ecliptic Survey at the Cerro Tololo Inter-American Observatory, and was announced in July 2001. The object is named after the Greek mythological figure Ixion, who was a king of the Lapiths. In visible light, Ixion appears dark and moderately red in color due to organic compounds covering its surface. Water ice has been suspected to be present on Ixion's surface, but may exist in trace amounts hidden underneath a thick layer of organic compounds. Ixion has a measured diameter of , making it the fourth-largest known plutino. Several astronomers have considered Ixion to be a possible dwarf planet, whereas other ...

2001 Insurgency In Macedonia
The 2001 insurgency in Macedonia was an armed conflict which began when the ethnic Albanian National Liberation Army (NLA) militant group, formed from veterans of the Kosovo War and Insurgency in the Preševo Valley, attacked Macedonian security forces at the beginning of February 2001, and ended with the Ohrid Agreement, signed on 13 August of that same year. There were also claims that the NLA ultimately wished to see Albanian-majority areas secede from the country, though high-ranking members of the group have denied this. The conflict lasted throughout most of the year, although overall casualties remained limited to several dozen individuals on either side, according to sources from both sides of the conflict. With it, the Yugoslav Wars had reached Macedonia. The Socialist Republic of Macedonia had achieved peaceful independence from Yugoslavia in 1991. Background When it declared its independence from Yugoslavia on 8 September 1991, Macedonia was the only ex- Yugoslav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Al-Qaeda
Al-Qaeda (; , ) is an Islamic extremist organization composed of Salafist jihadists. Its members are mostly composed of Arabs, but also include other peoples. Al-Qaeda has mounted attacks on civilian and military targets in various countries, including the 1998 United States embassy bombings, the September 11 attacks, and the 2002 Bali bombings; it has been designated as a terrorist group by the United Nations Security Council, the North Atlantic Treaty Organization (NATO), the European Union, India, and various other countries. The organization was founded in 1988 by Osama bin Laden and other volunteers during the Soviet–Afghan War. Following the withdrawal of the Soviets in 1989, bin Laden offered ''mujahideen'' support to Saudi Arabia in the Gulf War in 1990–1991. His offer was rebuffed by the Saudi authorities, which instead sought the aid of the United States. The stationing of U.S. troops in Saudi Arabia prompted bin Laden to subsequently wage ''jihad'' agains ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artificial Heart
An artificial heart is a device that replaces the heart. Artificial hearts are typically used to bridge the time to heart transplantation, or to permanently replace the heart in the case that a heart transplant (from a deceased human or, experimentally, from a deceased genetically engineered pig) is impossible. Although other similar inventions preceded it from the late 1940s, the first artificial heart to be successfully implanted in a human was the Jarvik-7 in 1982, designed by a team including Willem Johan Kolff, William DeVries and Robert Jarvik. An artificial heart is distinct from a ventricular assist device (VAD; for either one or both of the ventricles, the heart's lower chambers), which can be a permanent solution also, or the intra-aortic balloon pump – both devices are designed to support a failing heart. It is also distinct from a cardiopulmonary bypass machine, which is an external device used to provide the functions of both the heart and lungs, used only for ...

Human Genome
The human genome is a complete set of nucleic acid sequences for humans, encoded as DNA within the 23 chromosome pairs in cell nuclei and in a small DNA molecule found within individual mitochondria. These are usually treated separately as the nuclear genome and the mitochondrial genome. Human genomes include both protein-coding DNA sequences and various types of DNA that does not encode proteins. The latter is a diverse category that includes DNA coding for non-translated RNA, such as that for ribosomal RNA, transfer RNA, ribozymes, small nuclear RNAs, and several types of regulatory RNAs. It also includes promoters and their associated gene-regulatory elements, DNA playing structural and replicatory roles, such as scaffolding regions, telomeres, centromeres, and origins of replication, plus large numbers of transposable elements, inserted viral DNA, non-functional pseudogenes and simple, highly-repetitive sequences. Introns make up a large percentage of non-coding DNA. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exoplanet
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.

Galileo (spacecraft)
''Galileo'' was an American robotic space probe that studied the planet Jupiter and its moons, as well as the asteroids Gaspra and Ida. Named after the Italian astronomer Galileo Galilei, it consisted of an orbiter and an entry probe. It was delivered into Earth orbit on October 18, 1989, by , during STS-34. ''Galileo'' arrived at Jupiter on December 7, 1995, after gravitational assist flybys of Venus and Earth, and became the first spacecraft to orbit an outer planet. The Jet Propulsion Laboratory built the ''Galileo'' spacecraft and managed the ''Galileo'' program for NASA. West Germany Messerschmitt-Bölkow-Blohm supplied the propulsion module. NASA's Ames Research Center managed the atmospheric probe, which was built by Hughes Aircraft Company. At launch, the orbiter and probe together had a mass of and stood tall. Spacecraft are normally stabilized either by spinning around a fixed axis or by maintaining a fixed orientation with reference to the Sun and a star. ' ...

Io (moon)
Io (), or Jupiter I, is the innermost and third-largest of the four Galilean moons of the planet Jupiter. Slightly larger than Earth’s moon, Io is the fourth-largest moon in the Solar System, has the highest density of any moon, the strongest surface gravity of any moon, and the lowest amount of water (by atomic ratio) of any known astronomical object in the Solar System. It was discovered in 1610 by Galileo Galilei and was named after the mythological character Io, a priestess of Hera who became one of Zeus's lovers. With over 400 active volcanoes, Io is the most geologically active object in the Solar System. This extreme geologic activity is the result of tidal heating from friction generated within Io's interior as it is pulled between Jupiter and the other Galilean moons—Europa, Ganymede and Callisto. Several volcanoes produce plumes of sulfur and sulfur dioxide that climb as high as above the surface. Io's surface is also dotted with more than 100 mountains t ...
