microorganisms all around us. we continually danny moore about the origins of the universe and our planet. the complex ways various parts are interconnected as well as most. he's yet to be solved. welcome to tomorrow today the science show on d w. time has been around for well it seems like forever. the span of even a long human life is but the blink of an eye in terms of the cosmos archaeologists and palin tonnages stick up amazing stuff that reveals that by both our history and prehistory modern humans of the species homo sapiens emerged about 200000 years ago . the earliest traces of animals found so far date back 4000000000 years that's

just 600000000 years or so after our son took shape and roughly 100000000 years after the earth itself formed. and that's nothing compared to our galaxy as a whole the milky way it's more than 13000000000 years old. but it all began about 13800000000 years ago with the big bang at least that's the prevailing theory. a new telescope will soon reveal even more. the james webb space telescope will be able to peer far deeper into space than hubble the primary mirror measure 6.5 meters across that of its predecessor. it's comprised of 18 segments coded in a microscopically thin layer of gold. dominica village salak will be among the 1st

to conduct research using the new space telescope. her team is one of 13 that have been chosen to begin work as soon as it's up and running. with. lemon ah. i think that when you start to really delve into astronomy and realize that what we see with our naked eye when we look up at the starry sky is only a minute part of what is actually there it does something to you. i still get goosebumps when i think about it. as it stands out and. the astrophysicist is interested in super massive black holes embedded at the center of large galaxies as they devour the material around them they blast out powerful radiation and ultra fast winds. she says these winds can promote or prevent the

formation of stars in the galaxy. the link between black holes and the formation of galaxies is one of the most intensely studied fields in astrophysics. them and that's why. when you think about the size of a super massive black hole and the size of the galaxy that hosts it the difference is huge. it's like comparing a one cent coin with the moon. and yet during their active growth phase these super massive black holes are able to exert such an enormous influence on their galaxy. just how they do that is what she wants to understand after all we do live in a galaxy the milky way. even as a child to mimic a village salic began to wonder where the edge of the universe lies and what's

beyond it but during her childhood she never got a satisfactory answer. so she went out to study physics specialize in astronomy and land her dream job. and i thought there's a lot of about others as i'm just so happy to have the privilege of studying the universe as my profession. one about. and that i get to search out the secrets of the universe. and soon thanks to web she'll be able to study galaxies that are so far away that hubble can only make them out in low resolution. the new telescope will provide a much clearer view of these objects the light from the distant worlds has taken more than 12000000000 years to reach us so it dates back to a time when black holes were gobbling up huge amounts of material and blasting out

powerful winds. the data should reveal what effect that had on the galaxies around them. and the data won't just be 2 dimensional picture cut from a larger picture but 3 dimensional. going to die did in other words there is the spectrum hiding behind each and every pixel on that 2 dimensional image for. those spectra will show how much gas is contained in released just in galaxies how fast that gas is moving and eating and what direction it's moving. village salic says that data with allow us to understand better how galaxies are formed a filter wheel like this one is also installed in the camera that she will use to study those faraway galaxies it was developed here at the max planck institute for astronomy. as the launch date approaches the sense of anticipation is rising.

the james webb space telescope is due to start its mission next october 14 years later than originally planned when the thought of the hole to start out on as the launch date gets closer i'll probably start to dream about it right now i'm having nightmares that the whole thing will just blow up. the telescope is so big that both of its so-called. wings will need to be folded so that it can fit into the launch vehicle. there's never been a satellite with so many moving parts it will take 2 weeks to unfold everything in that time nothing make go wrong 6 months after the launch date the new telescope should finally be ready to begin studying the secrets of the universe. humankind has been puzzling over those secrets for millennia schools of smart and

brave people rack their brains and bodies to explore the universe some in space and many behind the scenes nancy grace roman was a leading astronomer at nasa she celebrated as the mother of the hubble space telescope that's yielded breathtaking views from the depths of space. far beyond earth's atmosphere the hubble space telescope has a crystal clear view of the universe from its vantage point it can see much that is not visible from the ground. in the sky has revealed the beauty of space and changed our understanding of the cosmos. yet the project was almost doomed when hubble began life short sighted. the catastrophic flaw was only found after launch when it sent fuzzy pictures back to

earth. fortunately hubble's construction allowed the problem to be rectified. a total of 5 servicing mission to corrected the optics and installed new instruments. that not only extended the life of the orbiting telescope the drilling missions made hubble. the world's best known telescope and help to sharpen the awesome images that captured. hubble's silent gaze open the way to trail blazing astronomical discoveries. it showed us that the universe is expanding at a constantly increasing rate a discovery that won the nobel prize for physics in 2011 thanks to hubble we also

know the universe is about 12 to 13000000000 years old. by looking deeper into space than ever before couple helped our understanding of how galaxies evolve. the data from the telescope reveals that most large galaxies have a supermassive black hole lurking at their center. hubble has given us new insights into the life of stars. how inside clouds of dust they are born. and how they die. images have enabled us to reconstruct these turbulent processes. more recently public has helped find exoplanets planets orbiting distant stars and even analyzed their atmospheres. if all goes according to plan the hubble

space telescope will continue to scan the cosmos until 2025 and perhaps enrich us with more exciting discoveries. hubble can actually be seen with the naked eye but only from certain regions of the end of . the space telescope delivers masses of data. respect to one of the people who uses that data to create stunning pictures. you could almost feel the scale and the size of the spillers and even on the images transforming into what we are a nation. you feel so much happening then you feel the light from the stars sculpting these pillars you see the different layers you see stars on the back row you see stars or on the screen these pillars in between it's really

a stunning setting out. of this little structures of this little. fingers in the gas it's bizarre that from from the stars being born which are shaping and carving the gas wrong. it's so absolutely stunning. it has that amaze but also inspire awe. they were created by martin kahn massa and luis posada a combination of science and art. oh you have them we wanted to know just how it's done so we set up an interview with luis posada which due to the coronavirus pandemic was conducted remotely.

and the cameras are not like there is no a photographic memories in the sense that they snap and it's a beautiful color for the image of the universe now the hubble gets the data of sort of the universe through this field they're going to build there is like a little leds that you put in front of the camera that only lets light of a certain wavelength or color passed through. and usually if you want to serve the full object we use many many films there's one of them in the other and then we combine the filters to make a color image. the colors are very very tightly connected to the real physical processes. after this we start fine tuning in a little bit. that's where the artist part comes in of course this is kind of like the real they come out and then strongly start adding a little bit more of. a contrast adjustments here and there there's

a lot of creative freedom we start with a real date that we combine ins with the real science but then of course there's ways in which we can try to combine this in a more aesthetically pleasing way. the main objective 99 percent of the time it's a is to collect danger that scientists are going to are going to research on it is not to make beautiful images. that's a side that's a side product you know what i mean. sometimes the images are not very aesthetically pleasing when we get the data the image can come. damaged a little bit with artifacts which the scientists don't care so to speak because they want to they care more about the data they care about the numbers. but we want to use these images for the public want to show these beautiful images for the public sometimes to make this little bridge between what the start of us need and

want and what b.n. public needs and that's about to be a bit of a challenge. i can hear him martin saying oh if only they would have composed it like this the other service their own thing you might get is just on the data from this region but sometimes we think act it's a clear what if b. image was a little bit more composed like this one tends. to move. and sometimes when we capture some of these images it feels like oh it's yeah it's just just something which is static but but just the spam scales are a bit different from what we humans are used to so whereas a kind of looks like oh just just stop the nose actually just violently you're.

changing. in mars a lot as it's actually interesting in just the course of a few years then 20 years we actually see a very beautiful light and because of the light is going through the gas it's around the year this binary stars and it's actually shining through and it's revealing more of this kind of like blossoming flower. it's really interesting to see that the entire life of human kind is a very very tiny blip in the history of the universe. they're filmed of gas the sun is setting like a bull so it's the n. l world is full of nationally occurring shapes patton's and symmetry both below and above was him. it may seem random but nature has its own intrinsic geometry i'll feel it from sydney wants to know more about one shape in particular. one are so many things in nature

around could it be some kind of pan galactic code the stars the planets including our own everywhere you look spears and circles are inches coconuts round lentils tomatoes to our eyes blood cells drops of water fear of the ground across the universe there's no getting around 3rd round thanks to fundamental physical phenomena. first gravity this is what enables large bodies like planets or stars to hold other objects in their orbit. but the larger the mass the greater the gravitational force and gravity pulls everything towards the center of a mass so when an object has a lot of mass it will tend to form a sphere where all points on the surface are at the same distance away from the

center so even our highest mountains will eventually flatten out and literally be brought back down to earth by gravity. another factor in the physics of round miss is the relation between surface area and volume a sphere is the most compact shape there is posting the smallest surface to volume ratio. in other words small on packaging big on context strictly speaking round shaped packets would be far more efficient. everything from flower stems to tree trunks have a round cross-section of the minimize surface area translates into better energy retention and less water evaporation plus less exposure to the elements roundness means stability which is why so many precious things in nature are more

or less round. eggs for example the start of life for countless animals. nature once again delivering an elegant marriage show form and function. as if you know you can't break a rule eg by squeezing it's the force dissipated even the a round the elliptical form and the fluid inside exists accounts of force if you don't believe us try it. and. many processes in nature are all cyclical. they sustain organisms and the environment but things can get out of sync. with we humans do and fail to understand what appears to be a self regulating system. the cycle of life takes us from the cradle to the

grave but what may seem like an end can be part of the beginning for other new value. animals die all the time and everywhere in german forests the corpses of larger animals are usually removed if they're found by hunters or foresters ecologist christiane fun herman is interested in what happens when they're left to rot as part of his. research he places dead animals in the forest at a good distance from any hiking trail. this roebuck was hit by a car and has been here for almost a week in the heat strong smell of decay spreads far and wide most humans find it disgusting many other species find it most appealing and come brushing the 1st arrivals or flies.

to comment that say they come from up to 3 kilometers away they really can smell it from such a great distance their mail a large batches of eggs these white specks 200 to 250 eggs in each batch. each female lays a batch of and a larva or maggot hatches from each egg each maggot eats 2 grams of flesh before it turns into a fly so if the conditions are right it doesn't take long for a deer to be entirely consumed with this is that when there are loads of maggots on a corpse there rub up against each other the temperature and the mass of maggots gets really high up to 30 degrees hotter than the air we once measured $47.00 degrees on a red deer the maggots create their own microclimate in which they develop that they can. come on lays insect traps next to the dead animals in order to find out which species come to visit. he often find some that

had never before been identified here and the bavarian forest national park. we found $112.00 species of beetle not usually found in traps with no corpse nearby we call this dark biodiversity the species you don't normally catch. beetles tend not to hang around a carcass they come devours. maggots then move on. the maggots congregate in the the corpse. and. only species that are already at home in the ecosystem find their way to corpses they only remain there however if there is an adequate supply of dead animals.

in the. sun burying beetles for example disappear very rapidly from areas where courses are absent or where there's a lot of human activity. her man has made a surprise discovery here dead flies with fuzzy backsides they've fallen victim to a toxic fungus and i'm off there must die. in german it's simply known as fly killer fungus if you get what the fungus infects the fly and kills it then the fungus grows out of the flies body so that its rare and looks bigger you can see that with the yellow rings male flies prefer larger females because they lay more eggs so a male copulates with an infected female gets contaminated with fungal spores and spreads them further into the ecosystem right up. also sets up camera traps near the corpses they reveal the larger animals which come by our robot for

a meal. links frequent corpses as to wolves and wild boar. some birds come for the beetles and maggots. raisins go for the flesh as do other carrion eaters and birds of prey. we've seen $800.00 species of large bird scavenging off a single corpse all in all including the insects this constitutes an incredible nutritional boost to the ecosystem a dead tree lying in the forest is an extremely important resource over the long term corpses an extremely important short term resource but one that recurs regularly on the entire system benefits of. dead wood and dead animals they all play their part in the ecosystem giving themselves so that others may flourish. the term

ecosystem can be applied even to communities of minuscule creatures in tiny spaces . if few drops of water in a garden hosts so much life. single celled organisms nematodes insect larvae mites elstree and bacteria to name but a few. some species eat the algae. one creatures excrement is another's dinner. which in turn nourishes the algae. they return the favor by producing oxygen which is lapped up by other microorganisms and so the carousel of life keeps turning.
