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.

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.

Ward and Brownlee use fossil evidence from the Burgess Shale in British Columbia, Canadato determine the climate of the Cambrian Explosionand use it to predict the climate of the future when rising global temperatures caused by a warming Sun and declining oxygen levels result in the final extinction of animal life. It's a grim reminder of what scientists think might happen to Earth if our Sun runs out of fuel, swells, and devours the inner solar system's planets. De saw when will the sun destroy the earth star that had brightened fold in a week one night.

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.

All life on Earth owes its existence to the sun's radiant heat. But what happens when that radiation surges out of control, and billions of tons of charged solar material suddenly barrel our way at thousands of miles a second? What happens when Earth takes a direct hit from a solar flare — and could a strong enough one ever destroy life on our planet as we know it? The answers are complicated, but most scientists agree on one thing: Earth's magnetic field and insulating atmosphere keep us extremely well protected from even the most powerful solar outbursts. While solar storms can tamper with radar and radio systems or knock satellites offline, the most harmful radiation is sopped up in the sky long before it touches human skin. Still, not all solar flares are harmless. Space weather experts at NASA and other agencies take this threat seriously, and closely monitor the sun for potentially hazardous activity. Solar flares occur when the sun 's magnetic field lines become taut and twisted, causing enormous, planet-sized storms of electromagnetic energy to form on the sun's surface. We can see these storms as cold, dark splotches known as sunspots. Around sunspots, huge tendrils of magnetic field lines twist, spool and sometimes snap, creating powerful flashes of energy, or solar flares.

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 a bumper crop of sunspots, solar storms and rare solar phenomena suggest solar maximum could arrive by the end of this year at the earliest — and several experts told Live Science we are poorly prepared.

Once the Sun changes from burning hydrogen within its core to burning hydrogen in a shell around its core, the core will start to contract, and the outer envelope will expand. This, in turn, can affect the climate, further lowering temperatures. Since its brightness increase, the star has produced only one thousandth of the energy through stellar mergers.

The total luminosity will steadily increase over the following billion years until it reaches 2, times its current luminosity at the age of This rate of removal would be sufficient to counter the effects of increasing solar luminosity for the next two billion years. Tayler, Roger John , Galaxies, structure and evolution 2nd ed. The formation of a supercontinent insulates the mantle. Tectonics -based events will continue to occur well into the future and the surface will be steadily reshaped by tectonic uplift , extrusions , and erosion. At this point, trees and forests in their current forms will no longer be able to survive. Mauna Loa should experience about eruptions over the next 1, years, and the Old Faithful Geyser will likely cease to operate. 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.

This is expected to continue, causing the plates to relocate and collide. The flow of heat will be concentrated, resulting in volcanism and the flooding of large areas with basalt. A steady release of carbon dioxide by volcanic eruption could cause the atmosphere to enter a "super-greenhouse" state like that of the planet Venus. The sun survives by burning hydrogen atoms into helium atoms in its core. This is expected to occur between 1. 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. So all of the planets orbiting the sun will drift a little farther away. However, underground life could last longer. Humans are excluded, luckily. But it might not be climate change that's our ultimate demise, but the sun engulfing our planet.
