Scientists have been looking into what the future holds for the sun and Earth, and it doesn't look very optimistic. The sun is located a whopping million km away, but can still wreak havoc here on Earth - global warming being an example. But it might not be climate change that's our ultimate demise, but the sun engulfing our planet.

When will the sun destroy the earth

The biological and geological future of Earth can be extrapolated based on the estimated effects of several long-term influences. These include the chemistry at Earth 's surface, the cooling rate of the planet's interior , the gravitational interactions with other objects in the Solar System , and a steady increase in the Sun's luminosity. An uncertain factor is the pervasive influence of technology introduced by humans, such as climate engineering , [2] which could cause significant changes to the planet. Over time intervals of hundreds of millions of years, random celestial events pose a global risk to the biosphere , which can result in mass extinctions. These include impacts by comets or asteroids and the possibility of a near-Earth supernova —a massive stellar explosion within a light-year parsec radius of the Sun. Other large-scale geological events are more predictable. Milankovitch's theory predicts that the planet will continue to undergo glacial periods at least until the Quaternary glaciation comes to an end. These periods are caused by the variations in eccentricity , axial tilt , and precession of Earth's orbit. Sometime in the next 1. The luminosity of the Sun will steadily increase, causing a rise in the solar radiation reaching Earth and resulting in a higher rate of weathering of silicate minerals. This will affect the carbonate—silicate cycle , which will cause a decrease in the level of carbon dioxide in the atmosphere. In about million years from now, the level of carbon dioxide will fall below the level needed to sustain C 3 carbon fixation photosynthesis used by trees. Some plants use the C 4 carbon fixation method to persist at carbon dioxide concentrations as low as ten parts per million. However, the long-term trend is for plant life to die off altogether. The extinction of plants will be the demise of almost all animal life since plants are the base of much of the animal food chain on Earth.

Jun, - by CMI. Astronomers witness star eat its own planet. Earth may share same fate. First-time scientists saw a sun-like star eat a planet. This may suggest Earth will be destroyed in million years. MIT, Harvard, Caltech, and other astronomers detected a Jupiter-sized planet orbiting a 1,times-larger dying star on May 10, Nature reported their results.

Update: On Oct. The new forecast more closely matches the timeframe laid out in this feature and agrees with the predictions of experts who spoke to Live Science about the upcoming solar maximum. From a distance, the sun may seem calm and steady. But zoom in, and our home star is actually in a perpetual state of flux, transforming over time from a uniform sea of fire to a chaotic jumble of warped plasma and back again in a recurring cycle. Every 11 years or so, the sun's magnetic field gets tangled up like a ball of tightly wound rubber bands until it eventually snaps and completely flips — turning the north pole into the south pole and vice versa. In the lead-up to this gargantuan reversal, the sun amps up its activity: belching out fiery blobs of plasma, growing dark planet-size spots and emitting streams of powerful radiation. This period of increased activity, known as solar maximum, is also a potentially perilous time for Earth, which gets bombarded by solar storms that can disrupt communications, damage power infrastructure, harm some living creatures including astronauts and send satellites plummeting toward the planet. And some scientists think the next solar maximum may be coming sooner — and be much more powerful — than we thought. Originally, scientists predicted that the current solar cycle would peak in

When will the sun destroy the earth

In a few billion years, the sun will become a red giant so large that it will engulf our planet. But the Earth will become uninhabitable much sooner than that. After about a billion years the sun will become hot enough to boil our oceans. This means that it is in the most stable part of its life, converting the hydrogen present in its core into helium.

The migration of Antarctica to the north will cause all of its ice sheets to melt. Fish and Wildlife Services, archived from the original on April 8, , retrieved July 16, As the understanding of geodynamics improves, these models will be subject to revision. The surviving liquid envelope will mainly consist of lighter elements that will undergo less mixing. These effects will counterbalance the impact of mass loss by the Sun, and the Sun will likely engulf Earth in about 7. The last surviving structures would most likely be open-pit mines, large landfills, major highways, wide canal cuts, and earth-fill flank dams. The planet may be entering another glacial period by this time. The tidal acceleration of the Moon slows the rotation rate of the Earth and increases the Earth-Moon distance. Industrial Automation and Machinery. With every pulse, the sun will shrug off layers of its outer atmosphere until all that's left is a hot, heavy core, surrounded by a planetary nebula. Origin abiogenesis Evolutionary history Biosphere Hierarchy Biology astrobiology. Christopher Scotese and his colleagues have mapped out the predicted motions several hundred million years into the future as part of the Paleomap Project. The biological and geological future of Earth can be extrapolated based on the estimated effects of several long-term influences.

Researchers debate whether Earth will be swallowed by the sun as it expands into a red giant billions of years from now. By David Appell.

This can be taken as an indication of the low likelihood of such an event occurring during the lifetime of the Earth. This would allow life to survive up to 2 billion years from now, at which point water would be the limiting factor. Contents move to sidebar hide. Rifts will form and the supercontinent will split up once more. These molecules cause a depletion of the ozone layer that protects the surface from ultraviolet UV radiation from the Sun. But, as stated above, without surface water, plate tectonics would probably come to a halt and most of the carbonates would remain securely buried [14] until the Sun becomes a red giant and its increased luminosity heats the rock to the point of releasing the carbon dioxide. The inner core is expected to consume most or all of the outer core 3—4 billion years from now, resulting in an almost completely solidified core composed of iron and other heavy elements.
