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.

When will the sun destroy the earth more massive stars can begin another shell of fusing heavier elements when this helium is exhausted, the sun is too feeble to generate the pressure needed to begin that layer of fusion, Scudder explained. From the perspective of humanity, these can be subdivided into survivable risks and terminal risks. 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.

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.

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

But even if our planet slips out of the sun's reach, the intense temperatures will burn it to a sad, dead crisp. 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. 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. 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. Chemicals and Materials. Should the human species become extinct, then the various features assembled by humanity will begin to decay. Next year, Palomar Observatory's infrared camera confirmed the source's cold material outflow. See: Weisstein, Eric W. The energy released from the impact of an asteroid or comet with a diameter of 5—10 km 3—6 mi or larger is sufficient to create a global environmental disaster and cause a statistically significant increase in the number of species extinctions. 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. When the sun becomes a full-blown red giant, Scudder said, its core will get extremely hot and dense while its outer layer expands Thank you for registering Please refresh the page or navigate to another page on the site to be automatically logged in Please refresh your browser to be logged in.

During the last million years, simulations demonstrated that such an impact rate is sufficient to cause five or six mass extinctions and 20 to 30 lower severity events. Medical Devices. Future of the Earth Future of an expanding universe Ultimate fate of the universe. These combined effects are expected to increase the length of the day by more than 1. Should the human species become extinct, then the various features assembled by humanity will begin to decay. Specialty and Fine Chemicals. In either case, this can result in the loss of the magnetic dynamo. Topics: Technology , News , Space , Science. In , for example, a computer simulation was used to predict that a reorganization of the mantle convection will occur over the next million years, creating a new supercontinent composed of Africa, Eurasia, Australia, Antarctica and South America to form around Antarctica. This could occur if natural processes were to remove the nitrogen from the atmosphere. Such events can be expected to continue.
