to protect the american people by tracking down and eliminating terrorist who seek to do us harm. scientists have produced further evidence that climate change is causing a sharp decline in bumblebee numbers in europe and north america. the creatures are key pollinators, playing a vital role in agriculture, but with current trends, there could be a mass extinction of bumblebees within a few decades. the research on the paper at the research on the paper at the university of ottawa told me the fall in number is astonishing. it really is quite drastic. when we first got the numbers, i could not believe them and had to run them at least seven times because they
and cools off and drops back down beneath the surface. and as part of the motion, magnetic fields are generated and you see those in the images as little bright features, little bright points which, for the first time, we have been able to resolve at their intrinsic scale. and that scale is extraordinary, isn t it? obviously you knew what you are trying to get. when you first saw the images what was your reaction? oh, i wasjust very, very happy. we have spent 25 years of work on this telescope. a whole team of engineers and scientists have basically put their life s work into this and seeing the images was the reward after all this work. we were just very, very happy. so, in more detail, what are the images telling you? these images let us resolve the magnetic fields which the sun generates
the workings of the sun. freya cole spoke to the director of the observatory. babbling away on the sun s surface are cell like structures known scientifically as solar granulation. never before have they been seen this close and for astronomers, this discovery is a big step towards unravelling many mysteries. i was just very, very happy. we have spent 25 years of work on this telescope. the whole team of engineers and scientists have basically put their lives work into this. the gold nuggets might look small under the telescope, but in reality they are about the size of texas. the bright centre is very hot plasma, the dark cracks are where it goes to cool. this is the machine inside the telescope used to capture the images. experts hope it will hold the information needed to predict the sun s
very, very happy. we have spent 25 years of work on this telescope. a whole team of engineers and scientists have basically put their life s work into this and seeing the images was the reward after all this work. we were just very, very happy. so, in more detail, what are the images telling you? these images let us resolve the magnetic fields which the sun generates on these very small scales, the size of manhattan. and we are looking at those from 93 million miles away. what we really want to accomplish with this telescope is to precisely measure the magnetic field, not only on the surface of the sun, but also in the upper atmosphere, in particular in the corona of the sun, so the corona is the outer atmosphere of the sun that you can see with your naked eye during an eclipse. what we currently cannot do is measure the magnetic field in the corona. and this telescope will let us do that. that s incredibly important
paul farnes, who‘s died at the age of 101. astronomers have revealed never before seen images of the sun. the striking high resolution images of our closest star‘s surface were captured by a solar telescope in hawaii. images showing what looks like a collection of gold nuggets will allow scientists to study the workings of the sun. freya cole spoke to the director of the observatory. babbling away on the sun‘s surface are cell like structures known scientifically as solar granulation. never before have they been seen this close and for astronomers this discovery is a big step towards unravelling many mysteries. i was just very, very happy. we have spent 25 years of work on this telescope. the whole team of engineers and scientists have basically put their lives work into this.
