And entered the space between the stars. >> its really amazing, and i know that there is a disk on board the spacecraft just in case there might be intelligent life out there that encounter voyager 1. tell us about that. >> this was a phonograph record, actually, a long-playing phonograph with grooves, and it does have various greetings from earth in different languages, music from earth in different cultures. it has sounds of earth, both natural and human made sounds, and has a little over 100 ...

And, finally... each correct response will begin with that letter. alex: where do we start? movies for $400. paul. who is tom cruise? correct. "g" for $400. jessica. what is the gallbladder? thats the "g." movies f0. jessica. who is adam sandler? right. movies for $1,200. paul. who is kristen wiig? correct. "g" for $800. jimmy? after radioactive decay, when a nucleus is in a high energy state, the particles and photons known as these rays are released. paul. [ clicks tongue ] what are gamma rays...

>> but the explosion at reactor 1 was just the beginning of things to come. >> theres a lot going on in japan right now. >> at the fukushima daiichi nuclear plant, along japans northeastern coast, four reactors are crippled by the earthquake when their power shuts down. >> they all shut down as theyre designed to immediately. but when a reactor shuts down, theres still radioactive decay going on there. >> making matters worse, back-up generators are designed to keep the water circulation system ...

murray is up to a jury. corporations raking in millions in profits and not paying taxes. sometimes the government is paying them. thats triggering outrage on this "american morning". good morning, everyone. it is friday, my very favorite day of the week besides saturday and sunday. happy friday. its november 4th. welcome to "american morning". >> im christine romans. ali is on assignment. hes still in caane. herman cain still defiant this morning. the republican front-runner push...

Reported this story, it was easy for nevada senator harry reid to tell us nuclear waste was safer right where it was. >> leave it on site, where it is. you dont have to worry about transporting it. it saves the country billions and billions of dollars. >> but japans crisis has democrats wondering if the effort to keep nuclear waste out of his state is really safer? >> i truly believe we must rethink how we manage spent fuel. >> if this was a rail fuel assembly, it would be 13 feet long and weigh...

The emergency electrical power. thats when the troubles began. viewers should know that when the reactors shut down there is still a lot of energy that needs to be taken away, a lot of radioactive materials that are still decaying, and that decay will fall off over time. so all the short-lived radioactive material that will decay over a period of days to a few weeks. we are still in a critical periodment its probably going to take another couple of weeks or so in order to get that radioactive de...

Ultimately flashs to steam and turns a turbine. they immediately install rods to bring the radioactive decay down to subcritical but they have leftover heat and residual radiation that has to be brought under control it will happen naturally within a few days. they are dog the best they can. a total meltdown only occurred at three mile island in 1979. that was a disaster of nuclear plant considered 10 times more serious than fukushima. the rods did meltdown, fell to the floor of the reactor buil...

Or tepko told everyone that they had the fire out. then it started again today. and what tepko is trying to convince us now is that it started today because they never actually but the it out yesterday. that would mean its been burning all along. or that the water levels have dropped so far they cant get enough water in there that its exposed. either one of those is a horrible situation. >> yes. my understanding is that the temperature by this cooling pool is so high that they cant -- they liter...

Create the hot water that ultimately flashs to steam and turns a turbine. they immediately install rods to bring the radioactive decay down to subcritical but they have leftover heat and residual radiation that has to be brought under control it will happen naturally within a few days. they are dog the best they can. a total meltdown only occurred at three mile island in 1979. that was a disaster of nuclear plant considered 10 times more serious than fukushima. the rods did meltdown, fell to the...

Theres huge defense and depth on these plans. they were designed to operate through an 8.2 quake. they survived this earthquake the tsunami took out some of the back-up systems. the ultimate back of up has been the reactor containment which are working. seawater option was built into the plant. this was not anticipated. it is something you dont want to do. you dont want to put seawater into the facility. but it was planned as an ultimate back-up if you needed it and it is working. >> sean: we he...
