Outer Space Disasters

99942 Apophis Asteroid 

99942 apophis asteroid

99942 Apophis  is a Near-Earth asteroid that caused a brief period of concern in December 2004 because initial observations indicated a relatively large probability that it would strike the Earth in 2029. However, additional observations provided improved predictions that eliminated the possibility of an impact on Earth or the Moon in 2029. A future impact on April 13, 2036, is still possible.

Asteroid 2007 WD5

2007 WD5 is a 48.77 m (160.0 ft) diameter Near-Earth object and a Mars-crosser asteroid discovered on November 20, 2007 by the NASA-funded Catalina Sky Survey on Mt. Lemmon, near Tucson, Arizona, USA, using a 1.5m telescope.  2007 WD5 is roughly the size of the cometary object that caused the Tunguska event in 1908 , in remote central Siberia, Russia.

Asteroid Impacts

An asteroid does not need to be large to devastate. One the size of a small garage would annihilate a large city. One big enough to leave a 10km crater, still nowhere near the size of the biggest (there is a 300km crater on Earth), would have the destructive force of every one of the world's 10,000 nuclear warhead combined.

Black holes

No, really - you just don't want to know this. There’s a remote, but extremely terrifying possibility our planet is about to be swallowed from within by a man-made black hole . In fact, our planet could be booby trapped with baby black holes already.

Eta Carinae

A near-Earth supernova is an explosion resulting from the death of a star that occurs close enough to the Earth (roughly less than 100 light-years away) to have noticeable effects on its biosphere. Eta Carinae sometimes has large outbursts, the last one just around its brightness maximum, in 1841.

Hypernova

A hypernova is a theoretical type of supernova produced when exceptionally large stars collapse at the end of their lifespan. In a hypernova, the core of the star collapses directly into a black hole and two extremely energetic jets of plasma are emitted from its rotational poles at nearly light speed. These jets emit intense gamma rays, and are a candidate explanation for gamma ray bursts.

Impact Event

Impact events are caused by the collision of large meteoroids, asteroids or comets with Earth and may sometimes be followed by mass extinctions of life . The collision between Earth and an asteroid a few kilometers in diameter may release as much energy as several million nuclear bombs detonating.

Galaxy Collision

The Milky Way and Andromeda collision is a predicted galaxy collision that is due to take place in approximately 3 billion years' time between the two largest galaxies in the Local Group – the Andromeda Galaxy and the Milky Way which contains the Earth.

Near Earth Object

Near-Earth objects (NEO) are asteroids, comets and large meteoroids whose orbit intersects Earth's orbit and which may therefore pose a collision danger . Due to their size and proximity, NEOs are also more easily accessible for spacecraft from Earth and are important for future scientific investigation and commercial development.

Near Earth Supernova

Speculation as to the effects of a nearby supernova on Earth often focuses on large stars as Type II supernova candidates. Several prominent stars within a few hundred light years from the Sun are candidates for becoming supernovae in as little as a millennium. One example is Betelgeuse, a red supergiant 427 light-years from Earth. Though spectacular, these "predictable" supernovae are thought to have little potential to affect Earth.

Supernova

supernova explosion star death

Supernova refers to several types of stellar explosions that produce extremely bright objects made of plasma that decline to invisibility over weeks or months. There are two possible routes to this end. A massive star may cease to generate fusion energy from fusing the nuclei of atoms in its core and collapses inward under the force of its own gravity, or a white dwarf star may accumulate material from a companion star until it reaches its Chandrasekhar limit and undergoes a thermonuclear explosion.

The End of Planet Earth 

end of planet earth

The end of planet Earth refers to hypotheses of when the Earth either completely ceases to exist as a planet or becomes uninhabitable for life. Most scenarios concerning the ultimate fate of the universe would subsequently destroy the Earth (in the unlikely event of Earth lasting that long).

The Tunguska Event

The Tunguska event was an aerial explosion that occurred at 60° 55′ North, 101° 57′ East, near the Podkamennaya (Stony) Tunguska River in what is now Evenkia, Siberia, at 7:17 AM on June 30, 1908. The size of the blast was later estimated to be between 10 and 15 megatons. It felled an estimated 60 million trees over 2,150 square kilometers.
