After the observatory obtained further confirmatory photographs, news of the discovery was telegraphed to the Harvard College Observatory on March 13, The discovery made headlines across the globe. The Lowell Observatory, which had the right to name the new object, received over 1, suggestions from all over the world; the name Pluto was proposed by Venetia Burney, an eleven-year-old schoolgirl in Oxford, England.

Venetia was interested in classical mythology as well as astronomy, and considered the name for the god of the underworld appropriate for such a presumably dark and cold world. Pluto officially became Pluto on March 24, Have a question?

In the inevitable physical destruction of the planet, a space is created where all notions of political, social and economic hierarchy will be at once obliterated and transcended. An edition of on black vinyl was released later. Both of these editions have now sold out. In July , an "ultra deep" blue vinyl edition of was released, exclusively available through Bandcamp and Rough Trade Shops.

In October , a further black vinyl copies were released.

Humans play a key role in the biosphere , with the large human population dominating many of Earth's ecosystems.

The consequences of a persistent biotic crisis have been predicted to last for at least five million years. Novel species may also emerge; in particular taxa that prosper in human-dominated ecosystems may rapidly diversify into many new species. Microbes are likely to benefit from the increase in nutrient-enriched environmental niches.

No new species of existing large vertebrates are likely to arise and food chains will probably be shortened. There are multiple scenarios for known risks that can have a global impact on the planet. From the perspective of humanity, these can be subdivided into survivable risks and terminal risks.

Risks that humanity pose to itself include climate change, the misuse of nanotechnology , a nuclear holocaust , warfare with a programmed superintelligence , a genetically engineered disease, or a disaster caused by a physics experiment. Similarly, several natural events may pose a doomsday threat, including a highly virulent disease, the impact of an asteroid or comet , runaway greenhouse effect , and resource depletion.

What is a Dwarf Planet?

There may also be the possibility of an infestation by an extraterrestrial lifeform. Should the human race become extinct, then the various features assembled by humanity will begin to decay. The last surviving structures would most likely be open pit mines, large landfills, major highways, wide canal cuts, and earth-fill flank dams. A few massive stone monuments like the pyramids at the Giza Necropolis or the sculptures at Mount Rushmore may still survive in some form after a million years. As the Sun orbits the Milky Way , wandering stars may approach close enough to have a disruptive influence on the Solar System.

Impacts from these comets can trigger a mass extinction of life on Earth. These disruptive encounters occur at an average of once every 45 million years. This can be taken as an indication of the low likelihood of such an event occurring during the lifetime of the Earth. This matches the geologic record of significant extinctions during the Phanerozoic Eon. Such events can be expected to continue into the future.

How and Why Do Planets Die?

A supernova is a cataclysmic explosion of a star. Within the Milky Way galaxy , supernova explosions occur on average once every 40 years. Explosions inside this distance can contaminate the planet with radioisotopes and possibly impact the biosphere. These molecules cause a depletion of the ozone layer that protects the surface from ultraviolet UV radiation from the Sun.

Resurrecting Interest in a “Dead” Planet

The incremental effect of gravitational perturbations between the planets causes the inner Solar System as a whole to behave chaotically over long time periods. This does not significantly affect the stability of the Solar System over intervals of a few million years or less, but over billions of years the orbits of the planets become unpredictable. There is a remote chance that the Earth will instead be captured by a passing binary star system, allowing the planet's biosphere to remain intact.

The odds of this happening are about one chance in three million. The gravitational perturbations of the other planets in the Solar System combine to modify the orbit of the Earth and the orientation of its spin axis. These changes can influence the planetary climate. In all 1, simulations, the planet's semimajor axis , eccentricity , and inclination remained nearly constant. Historically, there have been cyclical ice ages in which glacial sheets periodically covered the higher latitudes of the continents. Ice ages may occur because of changes in ocean circulation and continentality induced by plate tectonics.

The primary astronomical drivers are a higher than normal orbital eccentricity , a low axial tilt or obliquity , and the alignment of summer solstice with the aphelion. For example, the eccentricity changes over time cycles of about , and , years, with the value ranging from less than 0. The Earth is passing through an ice age known as the quaternary glaciation , and is presently in the Holocene interglacial period.

This period would normally be expected to end in about 25, years. On the other hand, a global warming period of finite duration based on the assumption that fossil fuel use will cease by the year will probably only impact the glacial period for about 5, years.

Thus, a brief period of global warming induced through a few centuries worth of greenhouse gas emission would only have a limited impact in the long term.

The tidal acceleration of the Moon slows the rotation rate of the Earth and increases the Earth-Moon distance. Friction effects—between the core and mantle and between the atmosphere and surface—can dissipate the Earth's rotational energy. These combined effects are expected to increase the length of the day by more than 1.

The distance to the Moon will increase by about 1. Based on computer models, the presence of the Moon appears to stabilize the obliquity of the Earth, which may help the planet to avoid dramatic climate changes. This is expected to occur between 1. A high obliquity would probably result in dramatic changes in the climate and may destroy the planet's habitability.

Tectonics -based events will continue to occur well into the future and the surface will be steadily reshaped by tectonic uplift , extrusions , and erosion. Mount Vesuvius can be expected to erupt about 40 times over the next 1, years. During the same period, about five to seven earthquakes of magnitude 8 or greater should occur along the San Andreas Fault , while about 50 magnitude 9 events may be expected worldwide.

Mauna Loa should experience about eruptions over the next 1, years, and the Old Faithful Geyser will likely cease to operate. The Niagara Falls will continue to retreat upstream, reaching Buffalo in about 30,—50, years. The planet may be entering another glacial period by this time. The theory of plate tectonics demonstrates that the continents of the Earth are moving across the surface at the rate of a few centimeters per year.
