and how much sun is actually good for us. hello and welcome to in good shape do you know those people who protect themselves from the sun regardless of the weather because sun is bad it harms your body but on the other hand. the sun is good for you it booth your immune system it makes you happy as a family doctor i would like to prescribe you suck but what are the dangers what is the right dosage and what are the side effects. when the weather's nice thomas folks prefer cycling to work he doesn't use u.v. protection happy to expose himself to the sun at specific times of the day he's a professor of dermatology and convinced that the sun is protective benefits also extent to our skin. when he's on a complex mind and if you avoid the sun completely and also use sun blockers and don't take vitamin supplements you're risking a serious vitamin d. deficiency the immediate impact is on your bones with a higher risk of osteoporosis but it also affects our health in general where the risk of cancer increases as opposed to internally t

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

europe's solar orbiter probe will make its first close pass of the sun today.ll track by a distance ofjust over 77 million km. the prone delete my probe was launched in february and it is ona probe was launched in february and it is on a mission to learn what makes the sun behave the way it does. chris, thanks very much for joining us. just talk us through the significance of what is happening today. actually, today is a landmark day for two reasons for those who are associated with the mission. first of all, we are on our first orbit after launch in february. we've reached a point in that orbit where we are closest to the sun. that's a big achievement. i've been watching my instruments getting warmer over the last few weeks. now i expect to see it start to get a little bit colder again. the other reason why it's an important day is today's actually formally the first day of our cruise space. we've spent the few months into launch checking out all the instruments making sure they are working, we completed that exercise. somewhat behind time because of the coron

because it's taking photographs of the sun and the sun is really bright, solar orbiter is not going asg a bit further back, 42 million kilometres away. and there it will use telescopes to take pictures through the heat shield, a heat shield which is partially made of baked animal bones. it's there to help solar orbiter withstand temperatures of up to 600 celsius. that is 1,112 farenheit. it's very important to keep solar orbiter and the instruments as clean as possible, and when there's dust on the lenses of the telescopes, when you expose that to the sun it effectively bakes those particles onto the lenses. once you start doing that you are losing science, so it's essential to keep those instruments as clean as possible. by measuring and capturing images at the same time, solar orbiter is really going to give us a good understanding of how the sun behaves, and how that can affect the technology we use here on earth. in today's world, with all our technology, a coronal mass ejection happens on the sun and affects us here on earth. it's going to have an impact on things like satellites,

every day and he projected the sun in a scream. and many pictures of drawings of the sunspots this black spots that in the surface of the sun where the magnetic field comes out and there were big ones and then he saw a flash of light where these dark spots just rode that and maybe picture it here had the day after that. the communications in in the whole world where perturbed the graphic stations were on fire and they didn't know what was going to non there are of course that people can have an hour we're seeing the northern lights there or us the whole sky was bright with light due to the least charged particles i have seen this current on astronomer in britain here had. travelled the way 2 years and produce this effect and what would happen if that happened today what really happened on the never of course on computers and if if an event injection like the carrington event happen today. g.p.s. will die and all the g.p.s. the. all the planes that now are traveling flying su these automatic pilots and they will be completely blind

up until the 16th century his observations led to the discovery that the planets revolve around the sun not the earth as people thought deed our celestial objects have been observed and studied since the beginning of time the planets and stars have helped us understand the cause of most the way it functions and its impact on our lives then in the 17th century. became the 1st astronomer to use a telescope for his observations the rest is cosmic history to date there's one question that most people want answered is there extraterrestrial life. in human and one of many observatories in a comma desert if the question of extraterrestrial intelligence is ever to be answered it is likely to come from here the is exceptionally blue skies and extremely dry atmosphere make this the ideal location for building the world's largest telescopes in fact so we will soon house 70 percent of global astronomical infrastructure even nasa comes right here to test its robots but what we will all these new facilities help us to discover and how will they change the way that we look at our you. of us 2 of chile

the sun has poles. i didn't know that and tell us more about these polls why is it important to locate them. so you know just like the air send all planets and the sun is a huge sphere. that is turning its rotating around itsts center so it does have pulled the north pole and the south pole. and we have never fleww above them with the telescope so this is the first time so this is why we want to go to see them. it's just likeke the e earth's boulders. as the post of the errors they are much different from thehe rest of the planets. and we didn't know that before going there. so it's's kinind oa new w exploratioion we want to . and i'm sorry to the region a region that we have never seen bebefore. absoluty amazing- you must feel like- a great pioneer the universe with what you have right now. well of my self. uniquely so we are thousands of engineers and s scientists workining coming north on the mission and w will work in the future. soo we are yeah we are modern explorers and pioneers. are discovering

even after a few minutes in the sun people with docs can sense it if to the sun and they do not need as intense sun protection fortunately ever what also counts is the cumulative sun exposure which people have to wring their life because this predispose us to skin cancer the greatest dangers of black and white skin cancers the so-called really no more than almost getting cancer. types at risk. no patience with fast skin this is skin type one and skin type 2 are at increased risk of both white skin cancer and black skin cancer malignant melanoma the most common types of skin cancer. types of skin cancer basal cell carcinoma. well ignat melanoma is less common but also more aggressive and unfortunately the incidence is increasing people with docs can develop may also develop malignant melanoma but sometimes at other parts of the body which are not so much exposed to the skin such as the fingernails the foot soldiers and the membranes what signs and symptoms should be watch out for white skin cancer often manifests quiet and suspiciously it looks like a red pepper to. which may grow and

so this mission will tell us about the sun...ally beautiful effect, but also it can be really damaging for satellite infrastructure and indeed, seven some of the infrastructure on the ground. so this mission is so important to space science and two space missions, but it is also very important to our everyday lives. give us a sense then, of the technical challenges involved in getting ourselves, you know, across several years getting ourselves, you know, across several yea rs into getting ourselves, you know, across several years into this precise position in relation to the sun. and so hot, and surviving that... yeah, exactly. it is quite a long way. so nearly 1 exactly. it is quite a long way. so nearly1 million miles to get to the sun and we are going about three quarters of the way there. from that position, we think we are getting the best vantage point and also, whilst we still have the capability to resist some of those tremendous temperatures that will be there, so we estimate temperatures of up to about 550 degrees, so t

our sun is seen in remarkable close—up detail.s taken by a solar orbiter reveal something we'd never seen before, small solar flares across the whole surface, which scientists have called campfires. seeing these images for the first time was breathtaking and when we look at the sun in these images we are able to see explosions happening all throughout the sun's atmosphere and we weren't expecting to see that, and that's the beauty of it, finding new things for the first time, seeing the sun in a new way, in a way we couldn't have imagined. clear the tower. the spacecraft started its mission in february. built in the uk, it's designed to cope with extreme temperatures as it nears our star. the earth is about 93 million miles from the sun and other missions have taken solar pictures from just above our planet. but on its first path, solar orbiter got much closer, within 48 million miles. and over the next two years it is heading closer still, within 25 million miles of the sun. this will give us a totally new view. in the next few y

compared to the earth the sun may be gigantic but among stars it's classified as a dwarf. astronomers classify stars based on the spectral characteristics of the light they emit. on a plot of their luminosity versus their color most stars appear in a continuous band known as the main sequence in the midst of it is our sun a fairly average star. the smallest stars are called red dwarfs. they use up their hydrogen so slowly that they're likely to continue burning for trillions of years our sun by contrast is expected to shine for just 12000000000 years. this nebula contains the heaviest star identified by astronomers to date researchers are mystified by how it could accumulate so much mass this colossal star is 265 times as massive as the sun and 10000000 times brighter. once it's exhausted its nuclear fuel it may explode in a supernova while its core collapses to form a dense neutron star or even a black hole all the chemical elements of the jets during this process are the building blocks for everything all the planets and even life everything we're made of including the i
