a huge fireball appeared at the center of our star the sun. the planets of continue to rotate around it to this day but what about the sun itself does it stand still. galileo was the first to observe dark spots on the sun surface back to me early seventeenth century with the help of a so-called heavier scope he was able to project the sun spots on the paper and mark that position. it was clear that the sunspots were moving indicating that the sun was rotating today such observations are made around the clock using data provided by satellites the sun rotates on its axis every twenty five days at its equator at the poles one rotation takes thirty five days so the surface of this fiery mass is actually moving at different speeds. and what about the sun's in a. completely hidden from view does it also rotate. last year that question was finally answered definitively. an international team of scientists managed to measure with high precision the rate at which the sun's core red tape. and they discovered that it actually moves much faster than the s

this close to the sun. the parkers solar probe will come 96 percent closer to the sun than earth and the outcome of this ambitious mission remains uncertain but this is the only way to explore how and when solar storms occur this is there's no question that a strong solar storm will happen in the near future it's just a question of time and we want to be as well protected as possible before. because of a solar storm catches us off guard he causes incredibly high temperatures capable of melting even the biggest transformers in substations as occurred in october 2003 in south africa a widespread abrupt power outage would put water works in their pumps out of service. at the same time pipelines would stop conveying oil because they too run on electricity extended power failures caused by transformer damage would bring nearly everything. to a standstill since even emergency power generators can only keep operating for so long scientists warn that everything would come to a stop and food shortages would occur. e

it was clear that the sun spots were moving indicating that the sun was rotating today such observations are made around the clock using data provided by satellites the sun rotates on its axis every twenty five days at its equator at the poles one rotation takes thirty five days so the surface of this fiery mass is actually moving at different speeds. and what about the sun's. completely hidden from view as it also rotates. last year that question was finally answered definitively. an international team of scientists managed to measure with high precision the rate at which the sun's core rotates. and they discovered that it actually moves much faster than the surface. they found out that. the rotation of the core of the sun. is significantly faster. in the rest. why factor three to four. how were the scientists able to look inside the sun to find out what was happening long is a helio seismologist he and his team at the max planck institute for solar system research study the oscillations on the surface of the sun these reveal a lot about the sun's structure and dynamics. sound waves are

so nickelodeon, avoid the sun, lie in the sun, enjoy the sun waving a sun hunt, and always fit in the shade. don't let the children play in the blazing sun is not valid or not even lawful. and by the way, there's no such thing as healthy. channing, every time you gave it a tear, not just a sunburn, but tanning that is a reaction of the skin to excessive song. sunscreen also helps white wrinkles and age spots. it prevents what no anti aging cream can undo. so remember using of sunscreen and reapplied every 2 hours, dispose of sunscreen after 6 months, and avoid direct sunlight if possible with and if he wants to know exactly how high the u. v levels are in your area, there were apps that will tell you the u. v. index. the w h o has just released its own up that covers all regions of the world. it gives advice to that strange as it sounds uv. radiation can also be beneficial to our house in certain cases. in fact, doctors can even use it as a skin treatment. yeah, the dosage is what makes something dangerous or not if that goes for u v a and b u v b radiation to model. how the police sc

produced to reach the sun's surface. the temperature there is $6000.00 degrees celcius for a cooler than the sun's atmosphere at a 1000000 degrees the corona can be seen with the naked eye during a total eclipse. our sun has been shining bright for around 4 and a half 1000000000 years despite its spectacular characteristics it's just another normal star like countless others in the milky way. once it's hydrogen has completely burned out the sun will expand and become what's known as a red giant by then it will have turned earth into a dead planet. since time immemorial human beings have understood the key role played by our sun it provides the earth with heat and light the sun the rich diversity of life on earth would never have developed. different peoples throughout human history have worshipped the sun and brought sacrificial gifts to win its favor. the sun also marks the progression from morning till night its course is a more accurate measure of days than the moon and of the seasons. in this way it served humanity a

the sun but the courts or corona. the camera needed to have a view angle that would capture the corona around the sun and for this purpose it had to be placed at a certain position on the probe. here where you have a model of the other whisper instrument and we'd like it to be in this position. of being. on the spacecraft. and just just about so. the camera would be very sensitive to light meaning that boatman and howard would have to prevent sunlight from being able to shine on to the camera's lens while it took photos of the corona. i think were said could you switch off the like walker yes and world order. to if it's important for the sunlight to be shielded off because the camera is meant to observe structures in the solar wind and the corona that are millions of times less bright. the heat of the sunlight is also so dangerous that the camera must always be protected by shade. after long consideration an agreement was reached on the concept and construction of the camera could begin. it owes its unusual shank to t

when that is an issue from the sun coming to work because we just sometimes on the sun gets angry and then the sun gets angry in the fries, a satellite system, the v as in to be saw at the startling constellation z z doesn't also satellites in space, thanks to us. so that's called so there are many benefits and not just didn't. yeah . but the where would be good. are you looking for the company? yeah. as one satellite. and this is coming straight on the back of in the successful in somebody on the mission. so it does really of move walk and not in the eyes on a certain thoughts. yes. uh so what is the high end india success and space exploration missions, as we mentioned just a week ago, atlanta to prove on the moon to be very hard work put in by the engine scientists and engineers would work as he'd get space and search organization of the headquarters, in fact it's an organization to be thankful to the island of excellence. it is seals, mediocre. d, which you guys have shown the pro is that they can make good satellites boot rockets and also to be planted exploration. the mission to

the temple of the sun is a masterpiece of inca architecture. it seems set into the rock like a condos nest. from the semicircular tower, the priests could make astronomical observations calculate the solstice, or determine the precise position of the sun, which played a vital role in religious ceremonies. sun and moon were at the center of all the incas sacred rights. the semi circular wall surrounds addressed block of granite, which resembles an altar and was presumably used for sacrifices at the center of matches. peach you lies the palace, the political heart of the city. the beauty and precision of the stone walls show that the priests and nobility ruled here to day. we know that the blocks were shaped with bronze and stone tools, and then ground against each other until the pieces fitted like a jigsaw puzzle. the trapeze shaped door and window openings are typical of inca architecture. they were important for the structural stability of the openings which were often surmounted by blocks of stone, weighing many tons the sacred plaza is also

sun protection. action factor after you've been in water although of course it depends how much you've been in the water if you showered afterwards and how vigorously you dried yourself with a towel so you shouldn't assume your sunscreen is waterproof you should always reapply it. so in order to ensure sun protection factor 50 all day long you need to apply a glassful of sunscreen over the course of the day. that's why no one does that if you apply that much sunscreen and one day you'd look like a breaded schnitzel. sunscreens can only provide a degree of protection against skin cancer that's due to the different wavelengths of the ultraviolet radiation of sunlight which is divided into uva and u.v.b. . also known theme if you use sunscreen you'll have less sunburn because sunscreen protects pretty well against ultraviolet b. but relatively poorly against ultraviolet a and it's uva that increases the risk of malignant melanoma. spots and how it's. sunscreen alone doesn't offer 100 percent protection

go directly to the sun.like a 5th of ok so here i am sitting on my rocket i have to get the speed right true. in e.-n. to the nasa scientists agreed that the probe should start off toward venus where it will be slowed down by passing by before continuing onward to the sun. this also significantly increases the available measuring times because the parker solar probe will not go around the sun just twice but 24 times. the european space agency e.s.a. is also working on solving the mystery surrounding solar storms and have also been developing their own probe for over 12 years called the solar orbiter. that is. a special thing about a star orbiter is its trajectory which will take us out of the plane of the sound system all our observations so far from the perspective of. and because all the planets revolve strictly within the plane of the solar system like on a record player it would take a lot of effort to escape this ecliptic and we feel what we are missing is data from the solar pole about the only way to

so nikolai and avoid the sun lie in the sun, enjoy the sun waving a sun hunt and always fit in the shade. don't let the children play in the blazing sun is not valid or not even lawful. and by the way, there's no such thing as healthy channing. every time you get a tear, not just a sunburn, but tanning that is a reaction of the skin to excessive song. sunscreen also helps white wrinkles and aged spots. it prevents what no anti aging cream can undo. so remember using of sunscreen and reapplied every 2 hours, dispose of sunscreen after 6 months, and avoid direct sunlight if possible with and if he wants to know exactly how high the u. v levels are in your area, there were apps that will tell you the u. v. index. the w h o has just released its own up that covers all regions of the world. it gives advice to that's strange as it sounds uv. radiation can also be beneficial to our health in certain cases. in fact, doctors can even use it as a skin treatment. yeah, the dosage is what makes something dangerous or not if that goes for u v a and b u v b radiation, 2 of them have a police. sca is a

the sun is one hundred fifty million kilometers away and it's. incredibly hot the temperature in the core reaches fifteen million degrees celsius as hydrogen nuclei combined to form helium this nuclear fusion has been the source of the sun's heat and light for more than four billion years. to what the sun looks like an evenly shaped ball but in fact it's a rotating and shape shifting gashes mass that generates a chaotic magnetic field the individual magnetic field lines can be seen as loops towering up to eighty thousand kilometers above the surface. of the field lines guide the motion of plasma and hot gases. just might move the magnetic field is constantly changing and twisting that means the magnetic field lines can cross each other that can cause the entire thing to become unstable you could picture it like elastic bands but a sudden they catapult it away if. this powerful solar eruptions occur repeatedly propelling millions of tons of solar gas and plasma into space. that can send a storm of electromagnetic particles hurtling towards our pla

a space probe the can approach the sun close enough to enter its atmosphere. the objective is to examine how solar flares formed. when currents of electronically charged particles hit the earth they threaten sensitive electronics and satellites that's why scientists want to be able to forecast devastating solar storms. the parker solar probe will gather the necessary data with four instruments this means coming closer to the sun than any other space probe as before. and to be successful it has to survive being showered by energy particles and extreme radiation this extremely hostile environment demands highly developed technology a carbon he chilled with a sickness of twelve centimeters on the probe enters the sun scorching atmosphere its surface will heat up to fourteen hundred degrees celcius the onboard computer has to continually readjust the heat shield so that electronic and measuring devices inside can remain at room temperature and keep working if the probe falters in some way unprotected parts will simply melt. with every approach to the sun the probe

i lots of sun further in the world. the sun bound for you is just one of a handful of feet. boundaries on demarcus who wants to use renewable energy when the sun isn't shining, or when the wind is blowing, then we need to have it stored. so we're looking at some simple se materials. harnessing energy as he's on this episode of transforming vistas based on here is beside the point of the sun storage. this is the size of what would be the world's biggest sun battery like or it's about that they made us, it'll be toner, then it's neighboring. a wood chip burning turned here in the small town of poor 9 and in southern finland. we are outside to replace here about 60 percent of our districts eating photos for double chips. and then further is able to fax me copa john and head of a finished district, cheese and company that's invested in the sun battery technology. it's building the battery to store renewable electricity as he's when needed be he's will then be sent back in 2.9 and district teasing network 2 and a half. i alw

the sun is the star for us. the system determines the size of the daily life of people across the world. what sort of digging is known about this one? that somebody disagrees about the sun that out a few groups around the sun by us and they go to be in space agency and all very soon the other one satellite joy in trying to decide for them any of this 3 the sun. it's a $2.00 and $1.00 mission, one that of scientific experiments. but there is also a component. we could have a full cost homes and a phone cost when that is an issue from the sun coming to work. the 3rd, which i sometimes cause the sun gets angry and then the sun gets angry if it could be fries a satellite system. the reason to be solved at this darleen constellation, losing the dozen or sole satellites in space, thanks to us. so there are many benefits and not just the we're looking for the company as one satellite and this is coming straight on the back of india, a successful in somebody on the mission. so it does really of moon walk and not in the

away from the sun. but further north you are the last receive. in december, the sun doesn't rise a tool in some arctic areas. mm. from march, the northern hemisphere stopped cleaning back towards the sun. the sun begins to climb higher and higher in the sky, and the days grow longer and longer until after that they start to get shorter again. and if i can start, i the changing of the seasons also affects whether wind rain, thunderstorms, almost all weather conditions occur within the lowest layer of the atmosphere. the troposphere, which urologist try to get accurate for cars so that we can back down the hatches when extreme weather is headed our way. but there's another type of weather space with it. we shouldn't take that to like the either the polar lights, the more than a spectacular light show from the heavens. they're also indicated of space whether the more intense ne, the curtains of light shine and the further towards the equator, they reach. the greater the danger posed by space, whether to ou

place where the sun is fatter.astronomers priests and teachers use the sun dial to calculate the course of the sun throughout the year the months and the time of day although we don't know what astronomical methods were used. the end of matthew picchu remains a mystery with the fall of the inca empire the decline of the city was probably inevitable after that it didn't take long for the jungle to reclaim the houses temples and rules and then the inca city of matches picchu slept for three hundred years. he started out with some junk and instructions from a book. at the age of fourteen william coming home by the dream. we wanted to build a wind turbine to provide his village with electricity. i want to elevate this idea change his life play football just such an exciting journey the world freek.

will we see the sun. it's not looking good we have this band of clouds that's come in from the west but maybe we'll be lucky and there'll be a break in the clouds i think he could have just. the final stretch a ridge. it's not looking sunny day no unfortunately not it's even started snowing flight. geologist immediately starts uncovering the rock on top of the trolls behind. where's the sun there behind the trout is it to show you this. and there's the one mountain here's the other and it's right here. through here hurt. but the sun's not visible. but it's there you know it's. dishonest. to. the polar night lasts for mid november to mid january during that time it's always dark that's when the residents of long aboon are on their own. on spitsbergen it's so dark that the reindeer switch off their internal clock day and night become one it doesn't matter when they sleep awake. people need to maintain their sleep patterns but alka cope well they geologist anelka an avalanche expert have lived on spitsbergen

so it doesn't cover the sun completely. that's uh and you get this, this sort of ring of fire around the outside of, of, of, of the shadow of the moon. i think that we're seeing the grounds now. it looks like complete and utter dark arts. things right now, let me just ask my producer what that is. that is this is this also indianapolis that we're seeing right now. this is, this is moving into a, this is the partial eclipse. yes. or the aspect that we talked about as it, as the moon slowly crosses the sun. actually it's not, it's not moving all that slowly. it's, you know, this, the shadow of the cast on the earth, the totality is moving along. this, this strip at about just under 2 and a half 1000 kilometers an hour. so it's nicely fast. it's pretty fast and, and the, that the amount of time that somebody who's on the ground will spend in the shadow of this totality. so in this total darkness is only about 3 and a half to 4 minutes. this is what, which is what we are seeing right here. now this one was in was yeah, right no

a space probe the can approach the sun close enough to enter its atmosphere. the objective is to examine how solar flares formed. when currents of electronically charged particles hit the earth they threaten sensitive electronics and satellites that's why scientists want to be able to forecast devastating solar storms. the parker solar probe will gather the necessary data with four instruments this means coming closer to the sun than any other space probe has before. and to be successful it has to survive being showered by energy particles and extreme radiation this extremely hostile environment demands highly developed technology a carbon he chilled with the thickness of twelve centimeters on the probe enters the sun scorching atmosphere its surface will heat up to fourteen hundred degrees celcius the onboard computer has to continually readjust the heat shield so that electronic and measuring devices inside can remain at room temperature and keep working if the probe falters in some way unprotected parts will simply melt. with every approach to the sun the p

so i'm coming to work the 3rd, which i sometimes call them the sun gets angry and the sun gets angry in the fries of satellites as conic systems. enough to be said to be saw that the startling constellation losing the dozen or sole satellites in space. thanks to us all. well there are many benefits and not just didn't. yeah. but the we're looking for the data coming from. yeah. as one satellite and this is coming straight on the back of in the successful in somebody on the mission. so it does really of move walk and not in the eyes on a sun box. yes. uh so what is the high end india success and space exploration missions, as we mentioned just a week ago, atlanta to prove on the moon to be very hard work put in by the engine. scientists and engineers will work at the get space and search organization the headquarters. in fact, it's an organization which i was in the island of excellence in the seals, mediocre, the guys. and they have shown the promise that they can make good satellites with rockets. and also do the planning exploration to the mission to study the mission, to study now

the sun but the course or corona. the camera needed to have a view angle that would capture the corona around the sun and for this purpose it had to be placed at a certain position on the probe. here we have a model of the of the whisper instrument and we've wife it to be in this position. of. on the spacecraft. and just just about so. the camera would be very sensitive to light meaning that boatman and how would would have to prevent sunlight from being able to shine on to the camera's lens while it took photos of the corona. i think were said could you switch off a light walker yes and we'll do it all 1st. rate if it's important for the sunlight to be shielded off because the camera is meant to observe structures in the solar wind and the corona that are millions of times less bright as. the heat of the sunlight is also so dangerous that the camera must always be protected by shade. after long consideration an agreement was reached on the concept and construction of the camera could begin. it owes its unusual shank
