with a country that some think is what america needs to do, that is write a new constitution. and he will speak to one of the top scientists responsible for the webb telescope and those awesome images it has captured. these videos show explosions that have happened in the last two weeks at russian military facilities in crimea, which has been occupied by russian forces since 2014. one attack at an air base destroyed at least seven russian warplanes. ukraine has claimed responsibility for that attack and two others according to an internal document obtained by cnn. is this evidence that kyiv is launching a counteroffensive against russia and could it gain back territory illegally overtaken by moscow? joining me now is retired u.s. army general mark hurtling. and general grks tohave good to have you on. great to be with you. let s talk about the attacks inside crimea, this territory has been controlled by russia for some eight years now. does ukraine s ability to strike beh
knew whatever is out there, we ll see it. when i think of it as a layman, what strikes me as extraordinary about this telescope is on the one side, it faces the sun and has this the heat that is facing is extraordinary. on the other side, it s facing cold temperatures like you can t imagine. describe how that works. the sun shield blanks out the sun and lets it cool down to almost the temperature of cold space. the temperature of the telescope. the 3 metric tons has to get to about 55 degrees kelvin, about minus 361 degrees fahrenheit. we can do that because we re looking at infrared wave lengths. anything that has a temperature like our bodies, ambient temperature, would glow. so we don t want it glowing brighter than the images that it is looking at. so that big tennis size sun
shield we have keeps it in the shade and allows it to cool. if that sun shield were sun tan lotion, you would say it had an spf of about 10 million. when you had about what this will help us learn, how should we think about what a telescope like this teaches us? again, i hear it as a layman. i think, are we going to learn a lot more about the big bang? because we re going back so far in time? well, it could potentially tell us some of the conditions in the early universe that could make some inferences as to the big bang. it will certainly tell us what the early universe was like. how that early universe fostered galaxy formation. the other big question that webb is fully capable of answering is looking for planets around other stars. exo planets that may have signsr
