what some think america needs to do. that is, write a new constitution. and then he ll speak to one of the top scientists responsible for the web 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 ukrainian government 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, a national security and military analyst for cnn. good to have you on this morning. great to be on this morning, jim. first, let s speak about these attacks in crimea, territory controlled by russia for some eight
i told people, if that sun shield were sun tan lotion, you would say it has an spf of about 10 million. wow. when you think about what this will help us learn, you know, how should we think about what a telescope like this teaches us? again, i hear it and 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 infrinferences of the bag and how that early universe fostered galaxy formation. and the other big question that webb is able to answer is looking for planets around other stars that may have signs of biomarkers, signs of elements or compounds that either are
out there, we re going to see this. what strikes me is extraordinary about this telescope is on the one side, it faces the sun and has this the heat that it s facing is extraordinary. on the other side, it s facing cold temperatures like you can t imagine. describe how that works. the sun shield blocks out the sun and lets the cold side passively cool down to almost the temperature of cold space, to the temperature of the telescope, the three metric tons of that telescope has to get down to about 55 degrees kelvin, which is about minus 361 degrees fahrenheit. it has to do that because we re looking in infrared wavelengths. anything that has a temperature like our body temperature would glow. so we don t want the telescope glowing brighter than the images it s looking at. so that big sun shield that we have keeps us in the shade and allows us to cool.
