and news from nasa of two planets that aren't unlike our very own it seems these planets can support life create a buzz as to what can be found our t. asks are we really alone. it's monday april twenty second to eight pm in washington d.c. i'm making lopez and you are watching our t.v. well we begin this hour in boston where the manhunt for the suspects responsible for the bombing of the city's annual marathon has ended but the investigation has only just begun the city of boston stopped for a moment of silence at two fifty this afternoon.

has the power to do any obligation to do and that's an alarm for the planet. today there must be there must be the koch brothers setting off the fire alarm in new york. let's get it together you know let's try and take it on let's go to brad johnson tyson slocum to lash out thank you all for joining thank you. coming up after the break there's not much difference between transportation the popular princeton's cartoon in transportation america today i will explain why and how we can change that in tonight's daily to a. potentially deadly blizzard taking aim for the northeast it's expected to hit stunning in a few hours from new york to maine we have team coverage of the storm. but what we're watching is the very heavy snow moving into boston proper earlier today it was very sticky you can see it start to become much more power. and there's still a lot of snow out here and a good place for snowball fight. to. it is kind of a pretty incredible day there and even record snowfall throughout what's it been like nobody's largely driving lessons from emergency vehicle

by planet for lifeforms themselves astronomers are searching for planets that are habitable in the first place now despite the vast expanse of the universe the chances of finding something like that are extremely narrow because most planets can't meet even the minimal requirements in order to sustain life and yet last week was a major breakthrough for astronomers when they located not one not two three habitable planets to talk more about this discovery i'm joined now by ian o'neill he's an astrophysicist and space producer with discovery news dot com. and so what exactly did the scientists discover in the light. constellation and what can we learn from the. well you know you mentioned that security was one star system actually changed two planets that are within the house a bull's eye on star. this system is secure interest school catholic sixty two this is particular interest because these are the smallest planets the full within the houses under the stars are being discovered now this star is a ritual source was kind of different from our star is older and it's smaller and it's less b

well given current climate change projections and the human consequences of a much hotter hotter planet hawking may not be too far off the mark and rather than investing in new science to explore the universe or change the way we use energy at home to slow global warming our lawmakers are pushing austerity and denying science you see the day after stephen hawking a scientist gave that warning about our planet congressman joe barton from texas a politician told us there's no need to worry about global warming because well the bible says so. people like me that support hydrocarbon development don't deny that the climate is changing i think you could have an honest difference of opinion on what's causing that change. without automatically. the end either all in it's all because of man and man candor it's all just natural i think divergence of evidence i would point out that if you're a believer in the bible. one would have to say the great flood is an example of climate change a good bargain is not a scientist stephen hawking is case that's not obvious also not a scientist republican congr

the key thing here is that these planets are in what's called the habital zone. that means distance from their start to be able to support earth like life forms. the third planet, kepler 69c orbits a star that's almost identical to our sun and it's also within the habital zone. these planets are earth...they don't know if they have atmospheres or if 1200 and 2700 light years from the earth. a huge sinkhole swallowed three cars early today. in a south chicago neighborhood. street fell in as the asphalt gave way under them. hole. out of the crater. and was taken to a local hospital. this sinkhole. >> pam:still ahead. the destruction in texas is stilleing assessed after a deadly fertilizer plant explosion. a live report from the scene coming up. plus: president obama and the first lady visit with the victims of the boston marathon bombing today. his words to a city in mourning. >> jacqueline: happening right now. the search continues for victims continues. after a massive fertilizer plant explosion in west, texas last night's blast claimed at least 5 lives. that num

, a planet with two suns.cience informs science fiction and sometimes science fiction informs science, right. >> reporter: hard to believe but despite the hundreds of trillions of stars in the universe, it wasn't until 1995 that scientists were 100% sure they had found a planet beyond our solar system. since then more than 800 planets have been found including 122 confirmed by kepler. some are freezing cold. think neptune at minus 360 degrees fahrenheit. some are scalding hot. think mercury which can reach 800 degrees. but the hunt is for what scientists call the goldilocks planet, not too hot, not too cold, making them a lot like earth. kepler researcher tom barkley found one of the first goalie locks. did you yell, did you go eureka. >> at some extent it was relief. finally we've done it. >> reporter: it helps to have a telescope in outer space and the use of a $100 million super computer to crunch the numbers. still that hint of dimming so many late years away is beyond miniscule. >> this is much less than,

that is not so, it might be sick as us, but the planet is fine, it can. what is suffering is our place on the planet which is fragile and other organisms will manage and thrive at the higher temperatures, like the mosquitoes that are spreading disease at alarming rates as the temperatures continue to climb. what is in peril is the future on this planet and the future of our children, we must recognize that what is needed to address this crisis is not simply the tunnel vision, but rather a piercing look at the whole and a overhaul of these factors, political social and economic that have put us in the situation in the first place, san francisco is a city that inspires people around the world as a beacon for visionary change and we are behind the times of other cities that have taken more approaches to address in climate crisis, i am asking the city to exist the courage needed to divest the pension funds from fossil fuels and stop to feed the cause and put that money into the sustainable solutions that offer a cure, i am asking the city to say how we can do

off to a distant planet over here. and people on this distant planet are gonna have a telescope all lined up here and they're gonna stand right here and they're gonna watch the flashes of light. and let's suppose a person here emits a flash of light every three minutes. this little flash, flash... i got a question for you. if there's no relative motion between the two planets, it's gonna take some time for that first flash to get up here. but under zero gravity here, boom, sees a flash. how long they're gonna have to wait for another one? three. - and the next one? - three. - and the next one? - three. they'll come at regularly spaced intervals, all right? now, let's suppose i have a rocket ship that's traveling at a very, very high speed between the two planets. now, this rocket ship is traveling away from the planet, the source of light. will that rocket ship see the flashes as often as three minutes apart or more compressed to more often than three minutes apart or kind of stretched out? check your neighbor. see, th

tornados, record temperatures, we go inside one man's desperate race to save our planet. >> we will never give up. >> keep it right here, america. "nightline" is back in 60 >> good evening. and thanks for joining us. we heard the dramatic story for days now, how one man went to check on his cherished boat and got the surprise of his life when he encountered one of the alleged bombing suspects. now for the first time today, that man david henneberry recounts the shocking turn of events. more on the latest developments. >> he is the man who owned the boat that played a starring role in this saga. >> the vessel iron clon named the slipaway 2 seen in this driveway in a backyard in water town with the suspect dzhokhar tsarnaev in a showdown with police. he gave an exclusive internet to the local boston affiliate. >> i look in the boat and i see blood. a good amount of the blood. henneberry stepped outside to check his beloved boat and that's when he saw it. my eyes wept to the other side of the engine box. there's a body. >> at that moment, what did you do? what were you thinking at that momen

. >> first a planet with hawaiian weather, the details about the new discovery. >> and after the break, forcing home owners to pay thousands to fix up their homes, the mandatory new program. >> it is a safety concern. i don't know who should pay for it. >>> former teacher plead no contest to 9 counts of having sex with a former student. she entered the plea. she worked as a math teacher. the abuse happened from december 2010 to may 2011. police say the relationship began through the cell phone app words with friends. >>> 13-year-old is the 6th suspect to be arrested in connection with the shooting death of a paramedic, quinn boyer. he was charged today, just 13 years old. also today a 16-year-old was charged with murder as an adult. he faces special circumstances to make him eligible for the death penalty. he is due in court tomorrow. those two along with four other teens are accused of killing the paramedic two weeks ago in an attempted carjacking. >>> today marks the 107 anniversary of san francisco's 1906 earthquake but a suspicious package prompted organizers to move the ceremony t

about my future and our future, at this very moment, the economic and environmental future of our planet and country are far from certain and now many refuse to acknowledge the nature of the climate crisis and the industry responsible for creating students and concerned citizens across the nation are getting organized and using the tactics at our disposal to leverage our voice and our demand for climate justice and we call on you to join us by moving this bill forward. as students at one of the top research institutions in the world, we will continue to work with the board and collaborate in the effort to move the assets away from the industry into clean and just technologies and companies that will bring the bay area and sf in particular close to a vibrant sustainable future, thank you for your time. >> thank you. >> next speaker please? >> my name is david seed and members of san francisco, tomorrow, citizen climate and lobby and as board members, we are at 1000 residents community in district five in the stone throw from the chamber, i would like to see it, my community, redevelop to

a hard day today to leave this lovely planet. >> absolutely. we had almost every type of climate you could want. 60s on the coast with some sunshine. cool conditions. 90s inland. let's take you outside right now, give you a sample of the microclimates around the bay area right now. san francisco, free of the low clouds. high clouds going by there. nice sunshine. south bay, same story. san jose, nothing but sunshine right now. it's not too breezy. we're seeing temperatures warming most places into the 80s inland. as you just saw, san francisco into the 60s. current temperatures around trivalley still a little toasty. stay in the 80s i think through the evening. ans t there towards dining pleasantton. 85 in santa rosa. all locations today really warming up compared to this time yesterday. at least 12 degrees warmer. 15 degrees warmer in santa rosa. we'll probably add another five degrees of warming to tomorrow's temperatures. the winds will be the story a little bit later this week. right now we still have a little sea breeze getting into the inn

let's build a smarter planet.: coming back for the hole-by-hole playoff. it will start here at 18 and if it's not settled at that point, they'll head over to 10, where it ended a year ago, and where cabrera won back in 2009 on that very green. and if it goes beyond those two holes, it's back to 18. that would be the rotation over and over again. there's never been, in all these playoffs since it went hole by hole, starting with fuzzy's win. a playoff here has never gone before -- beyond two holes. there's charlie s on the right. he's known cabrera for most of his life. he's a longtime pro at houston country club and longtime mentor to lange mcallister. a professional who had five ins here in america. harlie first met angel down at where de golf course charlie was working as the head pro. and somehow charlie has prepared angel for championship golf. nick: and both men are seriously motivated. adam scott, the whole country pulling for him. tough whole of argentina pulling for cabrera. and with roberto celebrating hi

we're fighting for the future of the planet. we're talking about more and more sandies and irenes, which cost huge amounts of money in terms of rebuilding those communities, not to mention the future disasters that we'll see. >> yet, here strikes me as the problem. on march 22nd, a symbolic vote in your august body, the senate, 72-37 against a symbolic resolution calling for approval of the keystone pipeline including democrats, quite a few, baucus, casey, connelly, and senator pryor of the great state of arkansas. >> i don't know how the president walks away considering he's appeared in the election period in front of the pipelines. he said he was waiting for the governor of alaska to approve routing. he's gotten studies. i don't know how he says no to keystone. even though he probably should. >> i want to ask after the break, how do you say no to keystone? and i want to hear your thoughts on your senator and how this might change his mind right after the break. >>> i have led the efforts in the house to support the keystone xl

and in 2006 as a graduate student, i was on a reporting team that branched out across the planet and went in to places where the impacts of climate change were being experienced by human beings up to that point much of the reporting and climate change was reported on the science and we had not heard much from the people, i went to an island called kirabos and met a man who was a village elder and they described a number of the facts that they have been experiencing as a result of climate change. that with the obvious ones like the sea level rise which causes the intrusion on the fresh water, where they get the fresh water from which is the corral nations. and also we saw a coastal erosion and disruptions to the patterns of migratory fish and that was in 2006 and since then we have seen so much in the united states from the super storms and fires and droughts and more. and you think that with such obvious evidence, staring our culture in the face that it would be less of a disconnect in this country, but unfortunately there still is. one piece of intrusion is there is a recent poll th

. >> my name iser on and thank you so much for taking the time to sponsor this our planet is at a cross roads, just last year the world bank agreed with the findings of the international payment on climate change from the united nations, and stated that we have about 3 years to enact sweeping legislation on climate change before we reached a tipping point downed which there is nothing to do. and in 2006 as a graduate student, i was on a reporting team that branched out across the planet and went in to places where the impacts of climate change were being experienced by human beings up to that point much of the reporting and climate change was reported on the science and we had not heard much from the people, i went to an island called kirabos and met a man who was a village elder and they described a number of the facts that they have been experiencing as a result of climate change. that with the obvious ones like the sea level rise which causes the intrusion on the fresh water, where they get the fresh water from which is the corral nations. and also we saw a coastal erosion and disrup

these kittens are so cute that this week animal planet is launching animal planet live, an entire networkam channels online. talk about zero production cost, people. the ten new channels allow you to watch cute animal porn all day, puppies, penguins, ants, birds, even cockroaches. some are cute. and animal planet hopes to make money paw over fist. they're running commercials every eight minutes. why are sponsors so excited to sign up? the average kitten cam viewer watches the page for 18 minutes and 50 seconds. that's right almost 20 minutes watching kittens sleep. we would kill for that here at cnn. and now we know the recipe, we have our own animal cam and it's not cute kittens or puppies. animal planet already cornered the market on that. tonight because it's hump day and this is "outfront," we're introducing the erin camel camera. for a full hour enjoy the sight of cam medicals in all their hump alicious dplo glory. tonight's essay is up next. a new property tax cap... and the lowest middle class income tax rate in 60 years... and a billion dollars in tax breaks and incentives. new op

this time both the planet and the population of it stood the impact. today we can say that this is the stone meteorite or a so-called right. type of meteorite is rather fragile and splits into fragments of all possible sizes. it was hit several times on its way to earth there's a lot of evidence for this. happened a long time ago. we're not aware of any cases of radiation related to meteorites as for microbes this is not the kind of meteorite that contains organic matter i would think it's full of earthly microbes from. the people of will have to face space threats many times in the future. a few days off the. american astrophysicist reportedly spotted six small asteroids approaching the. truth that it could be tomorrow or in twenty years i don't know his roots in theory humanity if it wants to live a long happy life or just live for us to think about it and the most advanced countries are already thinking about it and working on it. as a discussing the high probability of disaster in twenty thirty six when the doomsday asteroid will cross the bridge i

if there are to be benefits, it should benefit everyone on the planet. just like we did on the genome project which i happen to know a little bit about. >> yes, you do. thank you for joining me. you are watching "bbc world is america," still to come -- the world's largest particle accelerator is about to get more. we go inside to take a look. thethe residents of moscow, metro is a great way to avoid traffic jams and beat the cold. it is also an underground art museum. >> it is the morning shift on the metro. to anotherhis way world. beneath moscow, there are platforms. stations like museums. more than six and a half million journeys are made here every day. it is one of the busiest underground in the world. the metro is the lifeblood of moscow. this is what gets the russian capital moving. certain there is traffic jams and gridlocks above. the only reliable way to get around is out of the ground. -- reliable way to get around is underground. the metro is my home like every housewife, i like order. that is why if i see anyone dropping litter or vandalizin

the same thing you'd expect with planets in the universe. planets far--very, very massive, more force of gravity, close together, more force of gravity. same type thing with electrical forces. any questions at this point? wouldn't a minus be part of the constant or proportionality for the electrical force? class, i haven't even talked about constant and proportionality, but it-- do you know what lee was talking about when he talks about the constant or proportionality, gang? no. remember the constant or proportionality for force of gravity? if you took the force and divided it by this, you'd always get the same number, and that was that big g, 6.67 times 10 to the minus 11, okay. that was the constant or proportionality. over here, if you take the force between a couple of charge particles and divide that force by the charges and the distance between, you will get the same darn ratio no matter what set up you talk about. and that's the constant of proportionality and we call it k. over here we call the constant g. now we don't talk about a p
