Nuclear war

Nuclear warfare is a military conflict or political strategy in which nuclear weaponry is used to inflict damage on the enemy. Compared to conventional warfare, nuclear warfare can be vastly more destructive in range and extent of damage, and in a m... uch shorter time. A major nuclear exchange would have long-term effects, primarily from the fallout released, and could also lead to a "nuclear winter" that could last for decades, centuries, or even millennia after the initial attack. Some analysts claim that with this potential nuclear winter side-effect of a nuclear war almost every human on Earth could starve to death, While other analysts, that dismiss the nuclear winter hypothesis, calculate that with nuclear weapon stockpiles at Cold War highs, in a surprise countervalue global nuclear war, megadeaths to billions of casualties would have resulted but billions of people would nevertheless have survived the global thermonuclear war.As of 2014, only two nuclear weapons have been used in the course of warfare, both by the United States near the end of World War II. On August 6, 1945, a uranium gun-type device was detonated over the Japanese city of Hiroshima   more

Kim Jong-un (LOL)

Kim Jong-un is the supreme leader of the Democratic People's Republic of Korea. He is the son of Kim Jong-il and the grandson of Kim Il-sung. He has held the titles of the First Secretary of the Workers' Party of Korea, the Chairman of the Central M... ilitary Commission, First Chairman of the National Defence Commission of North Korea, the Supreme Commander of the Korean People's Army, and presidium member of the Politburo of the Workers' Party of Korea. He was officially declared the supreme leader following the state funeral for his father on 28 December 2011. He is the third and youngest son of Kim Jong-il and his consort Ko Young-hee.From late 2010, Kim Jong-un was viewed as heir apparent to the leadership of the nation, and following his father's death, he was announced as the "Great Successor" by North Korean state television. At Kim Jong-il's memorial service, North Korean Chairman of the Supreme People's Assembly Kim Yong-nam declared that "Respected Comrade Kim Jong-un is our party, military and country's supreme leader who inherits great comrade Kim Jong-il's ideology, leadership, character, virtues, grit and courage"   more

Asteroid impact

Asteroids are minor planets, especially those of the inner Solar System. The larger ones have also been called planetoids. These terms have historically been applied to any astronomical object orbiting the Sun that did not show the disc of a planet ... and was not observed to have the characteristics of an active comet, but as minor planets in the outer Solar System were discovered, their volatile-based surfaces were found to resemble comets more closely and so were often distinguished from traditional asteroids. Thus the term asteroid has come increasingly to refer specifically to the small bodies of the inner Solar System out to the orbit of Jupiter. They are grouped with the outer bodies—centaurs, Neptune trojans, and trans-Neptunian objects—as minor planets, which is the term preferred in astronomical circles. In this article the term "asteroid" refers to the minor planets of the inner Solar System.There are millions of asteroids, many thought to be the shattered remnants of planetesimals, bodies within the young Sun's solar nebula that never grew large enough to become planets   more

Black hole

A black hole is a region of spacetime where gravity is so strong that no particle or light ray entering that region can ever escape from it. The theory of general relativity predicts that a sufficiently compact mass will deform spacetime to form a b... lack hole. The boundary of the region from which no escape is possible is called the event horizon. Although crossing the event horizon has enormous effect on the fate of the object crossing it, it appears to have no locally detectable features. In many ways a black hole acts like an ideal black body, as it reflects no light. Moreover, quantum field theory in curved spacetime predicts that event horizons emit Hawking radiation, with the same spectrum as a black body of a temperature inversely proportional to its mass. This temperature is on the order of billionths of a kelvin for black holes of stellar mass, making it all but impossible to observe.Objects whose gravitational fields are too strong for light to escape were first considered in the 18th century by John Michell and Pierre-Simon Laplace   more

Solar flare

A solar flare is a sudden flash of brightness observed over the Sun's surface or the solar limb, which is interpreted as a large energy release of up to 6 × 10²⁵ joules of energy. They are often, but not always, followed by a colossal coronal mass e... jection. The flare ejects clouds of electrons, ions, and atoms through the corona of the sun into space. These clouds typically reach Earth a day or two after the event. The term is also used to refer to similar phenomena in other stars, where the term stellar flare applies.Solar flares affect all layers of the solar atmosphere, when the plasma medium is heated to tens of millions of kelvins the electrons, protons, and heavier ions are accelerated to near the speed of light. They produce radiation across the electromagnetic spectrum at all wavelengths, from radio waves to gamma rays, although most of the energy is spread over frequencies outside the visual range and for this reason the majority of the flares are not visible to the naked eye and must be observed with special instruments. Flares occur in active regions around sunspots, where intense magnetic fields penetrate the photosphere to link the corona to the solar interior   more

Supervolcano

A supervolcano is any volcano capable of producing a volcanic eruption with an ejecta volume greater than 1,000 km³. This is thousands of times larger than normal volcanic eruptions. Supervolcanoes can occur when magma in the mantle rises into the c... rust from a hotspot but is unable to break through the crust, and pressure builds in a large and growing magma pool until the crust is unable to contain the pressure. They can also form at convergent plate boundaries.Although there are only a handful of Quaternary supervolcanoes, supervolcanic eruptions typically cover huge areas with lava and volcanic ash and cause a long-lasting change to weather sufficient to threaten species with extinction   more

Global warming

Global warming and climate change both refer to the observed century-scale rise in the average temperature of the Earth's climate system and its related effects. Multiple lines of scientific evidence show that the climate system is warming. More tha... n 90% of the additional energy stored in the climate system since 1970 has gone into ocean warming; the remainder has melted ice, and warmed the continents and atmosphere. The observed increases in global average surface temperature and atmospheric carbon dioxide have been much faster in recent decades than the natural changes of previous millennia, and levels are now higher than at any time for hundreds of thousands of years prior.Scientific understanding of the cause of global warming has been increasing. In its fourth assessment the Intergovernmental Panel on Climate Change reported that scientists were more than 90% certain that most of global warming was being caused by increasing concentrations of greenhouse gases produced by human activities. In 2010 that finding was recognized by the national science academies of all major industrialized nations   more
