But there is a physical explanation, and the way to see it for yourself is to think about the volume of the Sun. And this process, for as long as it endures, injects a tremendous amount of energy into a confined volume of space. Starts With A Bang is now on Forbes, and republished on Medium on a 7-day delay. The source of its power lies deep in its central core, which is like a continually exploding nuclear bomb giving out enormous amounts of energy. On the other hand, the overwhelming majority of the Sun's energy comes from the hottest regions; 99% of the Sun's energy output comes from regions at 10 million K or hotter, despite the fact that such a region makes up only a small percentage of the core's volume. The nuclear explosion compresses and heats the material inside, achieving the high temperatures and densities necessary to ignite that runaway nuclear reaction. The Sun is the source of the overwhelming majority of light, heat, and energy on Earth's surface,... [+] and is powered by nuclear fusion. Similar temperatures are now routinely and safely generated in nuclear fusion … (paper burns at around 233 degrees Celsius.) It’s a reaction that’s relentless and continuous, like a wood-fired oven except hotter, denser, and running on nuclear fuel. Neither energy nor energy-per-unit-time can successfully explain why atomic bombs can reach higher temperatures than the Sun’s core. A hydrogen bomb, where a nuclear fission reaction compresses the fuel pellet instead, is an even more extreme version of this, producing greater temperatures than even the center of the Sun. By contrast, inside the Sun, the temperature is a relatively cool ~6,000 K at the edge of the photosphere, but rises as you travel down towards the Sun’s core through the various layers. Every second, this fusion causes the Sun to burn through 700 million tons of fuel, much of which gets converted into energy via Einstein's E = mc². It’s a great question with a fascinating answer. The interior of the Sun is one of the most extreme places we can imagine. The nuclear explosion compresses and heats the material inside, achieving the high temperatures and densities necessary to ignite that runaway nuclear reaction. Nuclear reactions involving fission or fusion (or both, as in the case of Ivy Mike) can produce tremendously dangerous, long-term radioactive waste, but they also can produce temperatures exceeding those at the Sun's center. a density of 150 grams-per-cubic-centimeter, about 150 times the density of water. Cause it can take so much heat then when the sun beams down on it then the process gets alot more complicated it gets a little hotter than it starts to get more and more hotter. This cutaway showcases the various regions of the surface and interior of the Sun, including the... [+] core, which is where nuclear fusion occurs. Despite things like flares, coronal mass ejections, sunspots, and other complex physics occurring in... [+] the outer layers, the Sun's interior is relatively steady: producing fusion at a rate defined by its interior temperatures and densities at every internal layer. When nuclear fusion occurs, even greater amounts of energy are released, epitomized by the Soviet Union’s 1960 detonation of the Tsar Bomba. When our Sun runs out of hydrogen fuel in the core, it will contract and heat up to a sufficient degree that helium fusion can begin. The highest temperatures come in the earliest moments of ignition, before the volume of the explosion dramatically increases. Neither energy nor energy-per-unit-time can successfully explain why atomic bombs can reach higher temperatures than the Sun's core. (U.S. DEPARTMENT OF ENERGY)The center of our Sun tops out at 15 million K, but nuclear bombs can get nearly 20 times hotter. Nuclear bombs can certainly get as hot as the surface of the sun. The 1961 Tsar Bomba explosion was the largest nuclear detonation ever to take place on Earth, and is... [+] perhaps the most famous example of a fusion weapon ever created, with a 50 megaton yield that far surpasses any other ever developed. That’s how, here on Earth, we can produce something — albeit just for an instant — that truly is hotter than even the center of the Sun. Deep inside our Sun, nuclear fusion transform enormous quantities of hydrogen into helium, producing energy in the process. [...] What I don't get is this: some mid-sized thermonuclear test detonations done by the old Soviet Union and the USA have been recorded at (if only very briefly) 200 or even 300 million degrees Celsius. Deep inside our Sun, nuclear fusion transform enormous quantities of hydrogen into helium, producing energy in the process. By almost every meaningful metric, the Sun far outclasses anything we can create on Earth, including mass, energy, volume, power, and the sustained output of what is produced. I am a Ph.D. astrophysicist, author, and science communicator, who professes physics and astronomy at various colleges. the outer layers, the Sun's interior is relatively steady: producing fusion at a rate defined by its interior temperatures and densities at every internal layer. The highest temperatures come in the earliest moments of ignition, before the volume of the explosion dramatically increases. Treknology: The Science of Star Trek from Tricorders to Warp Drive, Beyond the Galaxy: How humanity looked beyond our Milky Way and discovered the entire Universe. “A nuclear bomb is like bringing a piece of the sun to the surface of the earth for a fraction of a second, and everything within a certain distance would just flash into fire,” Robock said. The most powerful nuclear detonations on Earth and the interior of the Sun actually have a lot in common. these reactions take place over a much shorter amount of time on Earth than in the Sun, and therefore, the total amount of energy released. Yes, there's an enormous amount of energy being emitted, but the Sun is huge. The mushroom cloud resulting from the nuclear weapon test Bravo (yield 15 Mt) on Bikini Atoll. The test was part of the Operation Castle in 1954, and was one of the strongest (but not THE strongest) Hydrogen bombs ever detonated. If you look at total energy, there’s no comparison. But without the quantum rules that govern the Universe at a fundamental level, fusion wouldn't be possible at all. a power density of about 300 watts-per-cubic-meter, about the same power output as a warm-blooded human’s body heat. That’s the most important realization when it comes to understanding how a terrestrial nuclear explosion can reach higher temperatures, particularly over a very short time interval, than the hottest part of our Sun can. The same thing that happens with a thermonuclear bomb happens during nuclear fusion on the sun. Look at an efficient fission bomb. For comparison, the Tsar Bomba â€” whose explosion all occurred in a fraction-of-a-second within a volume less than one cubic meter â€” converted more than 2 kg of mass (about 5 pounds' worth) into pure energy. at the incredible temperatures of 15 million K, the maximum achieved in the Sun, the Sun produces less energy-per-unit-volume than a typical human body. Follow me on Twitter @startswithabang. In a hydrogen bomb explosion, nuclear fission compresses an internal pellet, which then undergoes nuclear fusion in a runaway, energy-releasing reaction. (Or kelvin, whose units we'll use from now on.) For the early, single-stage atomic bombs we had on Earth, that meant the initial detonation was where the highest temperatures occurred. Nuclear reactions involving fission or fusion (or both, as in the case of Ivy Mike) can produce tremendously dangerous, long-term radioactive waste, but they also can produce temperatures exceeding those at the Sun's center. Archived. They both get the overwhelming majority of their energy from nuclear fusion: compressing light nuclei into heavier ones. You may opt-out by. It’s not even about power, or the energy released in a given amount of time; the Sun has the atomic bomb beaten by a wide margin in that metric as well. The Sun emits the equivalent of 4 × 10²⁶ J of energy each second, by comparison, some 2 billion times more energy than the Tsar Bomba gave off. A UK-based private venture has built a fusion reactor that can generate temperatures that are hotter than the center of the sun. 110. In particular: For a very small amount of time, until adiabatic expansion causes the volume of the explosion to increase and the temperature to drop, a nuclear explosion can out-heat even the center of the Sun. But in terms of temperature, we’ve got the Sun beat. At temperatures of 15 million K and matter compressed to densities 150 times as great as liquid water on Earth, it’s hot and dense enough for nuclear fusion to proceed continuously, outputting 300 J of energy each second for every cubic meter of space. This mass difference means that the "missing mass" gets converted into energy via Einstein's famous equation. The Sun's volume, however, is large enough to contain over 10^28 full-grown humans, which is why even a low rate of energy production can lead to such an astronomical total energy output. AP Photo/Goddard Space Flight Center. Jump directly to the content The Irish Sun, A … Why Do Octopuses Punch Fish? Nuclear bombs produce heat much hotter than the core of our sun, although for just a little while. Yes, there’s an enormous amount of energy being emitted, but the Sun is huge. It's a great question with a fascinating answer. This mass difference means that the “missing mass” gets converted into energy via Einstein’s famous equation. Is there anything hotter than fire? But a multi-stage hydrogen bomb, where a fission bomb causes the inner core to compress, achieving higher densities from the compression than even at the Sun’s center. Giving off 300 W of power per cubic meter is about the same amount of power that you give off throughout the day in terms of heat energy, burning through your chemical-based fuel to maintain your warm-blooded body temperature. But in a multi-stage atomic bomb, a small fission bomb is placed around material that’s suitable for nuclear fusion. Let's find out. As time goes on, the helium-containing region in the core expands and the maximum temperature increases, causing the Sun's energy output to increase. The most powerful nuclear detonations on Earth and the interior of the Sun actually have a lot in common. Your Christmas Night Sky Revealed: 12 ‘Christmas Stars’ And What To Point A New Telescope At, Shattered Chromosomes Help Create Drug-Resistant Cancer Cells. On the other hand, the overwhelming majority of the Sun’s energy comes from the hottest regions; 99% of the Sun’s energy output comes from regions at 10 million K or hotter, despite the fact that such a region makes up only a small percentage of the core’s volume.
