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. Justdancekids 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, when will the sun destroy the earth, there will come a day when our own sun will eventually destroy us.

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.

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. A new paper appearing in The Astrophysical Journal looks into Rho Coronae Borealis - a yellow dwarf star that's not dissimilar to our own sun. The star is around the same mass, radius, and luminosity as the sun, with the main difference between the two being their ages. Rho Coronae Borealis is thought to be around 10 billion years old, while the sun is half of that. Researchers found that the star is nearing the end of its lifecycle, meaning it will eventually turn into a red giant. 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. Stephen R. Kane, from the Department of Earth and Planetary Sciences, University of California , Riverside, is the sole writer of the study and explained: "Post main sequence stellar evolution can result in dramatic, and occasionally traumatic, alterations to the planetary system architecture, such as tidal disruption of planets and engulfment by the host star. The process of it turning into a red giant isn't expected to occur for another billion years, though.

Niamh Shackleton. Each of these effects occur cyclically. Rifts will form and the supercontinent will split up once more.

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.

Today, the sun is an essential source of gravity and energy. But one day, it will cause Earth's demise. As the solar system 's central star ages, its life cycle will eventually consume our blue marble. So how long does Earth have until the planet is swallowed by the sun? Expected time of death: several billion years from now. But life on Earth will end much, much sooner than that. Earth will become unlivable for most organisms in about 1. And humans could potentially drive ourselves and countless other species to extinction within the next few centuries, if the current pace of human-made climate change isn't mitigated, or as a consequence of nuclear war.

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. For a star the size of ours, this phase lasts a little over 8 billion years. Our solar system is just over 4. In a star, gravitational force pulls all the gases towards the centre. When the star has hydrogen to burn, the creation of helium produces enough outward pressure to balance out the gravitational pull. But when the star has nothing left in the core to burn, gravitational forces take over. Eventually that force compresses the centre of the star to such a degree that it will start burning hydrogen in a small shell around the dead core, which is still full of helium.

De discovered compounds that could only be synthesized at extremely low temperatures, indicating the source was not binary. Join thought-provoking conversations, follow other Independent readers and see their replies. 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. Antarctica will reverse direction and return to the South Pole, building up a new ice cap. All of these changes can result in more rapid biological evolution as new niches emerge. Consumer Goods. Researchers Found New Form of Dementia ICT, Automation, Semiconductor In the extroversion model, the older, exterior, Pacific Ocean remains preferentially subducted and North and South America migrate toward eastern Asia. This can be taken as an indication of the low likelihood of such an event occurring during the lifetime of the Earth.

But this is still billions of years away, so it's likely climate change will get us first if we don't buck our ideas up, folks. Should the human species become extinct, then the various features assembled by humanity will begin to decay. Thus plants using C 4 photosynthesis may be able to survive for at least 0.

This, along with the melting of the Greenland ice sheets , will raise the average ocean level by 90 m ft. The surviving liquid envelope will mainly consist of lighter elements that will undergo less mixing. Once the orbit of the Moon closes to a distance of 18, km 11, mi , it will cross Earth's Roche limit , meaning that tidal interaction with Earth would break apart the Moon, turning it into a ring system. Four billion years from now, the increase in Earth's surface temperature will cause a runaway greenhouse effect , creating conditions more extreme than present-day Venus and heating Earth's surface enough to melt it. Mount Vesuvius can be expected to erupt about 40 times over the next 1, years.

The water then acts as a greenhouse gas, which traps more incoming heat, which speeds up the evaporation. The loss of the oceans could be delayed until 2 billion years in the future if the atmospheric pressure were to decline. South America will wrap around the southern tip of Africa. Should the human species become extinct, then the various features assembled by humanity will begin to decay. Researchers Found New Form of Dementia With each passing day this core, known as a white dwarf, will cool and fade hopelessly out of existence into a cold black dwarf , as if it didn't once host the most lively planet ever discovered in the sweeping canvas of the universe. Friction effects—between the core and mantle and between the atmosphere and surface—can dissipate the Earth's rotational energy. As the Sun orbits the Milky Way , wandering stars may approach close enough to have a disruptive influence on the Solar System.
