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.

When will the sun destroy the earth

There are plenty of ways Earth could go. It could smash into another planet, be swallowed by a black hole, or get pummelled to death by asteroids. There's really no way to tell which doomsday scenario will be the cause of our planet's demise. But one thing is for sure - even if Earth spends the rest of its aeons escaping alien attacks, dodging space rocks, and avoiding a nuclear apocalypse, there will come a day when our own sun will eventually destroy us. This process won't be pretty, as Business Insider's video team recently illustrated when they took a look at what will happen to Earth when the sun finally does die out in a blaze of glory. And as Jillian Scudder, an astrophysicist at the University of Sussex, explained to Business Insider in an email, the day might come sooner than we think. The sun survives by burning hydrogen atoms into helium atoms in its core. In fact, it burns through million tonnes of hydrogen every second. And as the sun's core becomes saturated with this helium, it shrinks, causing nuclear fusion reactions to speed up - which means that the sun spits out more energy. The water then acts as a greenhouse gas, which traps more incoming heat, which speeds up the evaporation. And it doesn't end there. And as the steady thump of time drums down on our existence, the situation will only get more bleak. All good things eventually come to an end. And one day, about 4 billion or 5 billion years from now, the sun will burn through its last gasp of hydrogen and start burning helium instead.

Elements of nature. The most rapid part of the Sun's expansion into a red giant will occur during the final stages, when the Sun will be about 12 billion years old.

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.

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. For a star the size of ours, this phase lasts a little over 8 billion years.

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.

The largest structures have an estimated decay half-life of about 1, years. ICT, Automation, Semiconductor According to scientists, there are four known orbiting planets around Rho Coronae Borealis and they will be impacted by the stellar atmosphere of the transition. In the modern era, the radius of the inner core is expanding at an average rate of roughly 0. It is likely to expand to swallow both Mercury and Venus, reaching a maximum radius of 1. December , "The life span of the biosphere revisited", Nature , : —23, Bibcode : Natur. These adaptations are likely to appear near the beginning of the moist greenhouse see further. The result of this process has been a steady increase in the energy output of the Sun. Download as PDF Printable version. See also: Faint young Sun paradox and Medea hypothesis. 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. However, without oxygen replenishment by plant life, they believe that animals would probably die off from asphyxiation within a few million years. Reliability and Reputation. At this point, trees and forests in their current forms will no longer be able to survive.

All life on Earth owes its existence to the sun's radiant heat.

November , "Solar interior structure and luminosity variations", Solar Physics , 74 1 : 21—34, Bibcode : SoPh Raven; Tania Williams eds. The consequences of a persistent biotic crisis have been predicted to last for at least five million years. The primary astronomical drivers are a higher than normal orbital eccentricity , a low axial tilt or obliquity , and the alignment of the northern hemisphere's summer solstice with the aphelion. In the modern era, the radius of the inner core is expanding at an average rate of roughly 0. 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.

Read Edit View history. What proceeds after this depends on the level of tectonic activity. These molecules cause a depletion of the ozone layer that protects the surface from ultraviolet UV radiation from the Sun. This is the latest accepted revision , reviewed on 24 February
