Transcript for Rare 'Blood Moon' on the Rise
Well what I'm -- Cutler in New York a blood moon. On the rise the first total -- -- clips from North America in more than two years will reveal itself early Tuesday morning bringing with it. Haunting display that some say. When actually -- bringing with some evil -- -- for more on the site and superstitious I don't want to bring in scientists from NASA doctor Michelle Boller at the Goddard Space Flight Center in Greenbelt Maryland -- thought thanks for being with us we appreciate it. Great debater show some folks are calling tonight's event a blood moon doomsayers calling it an evil -- What exactly is happening. Well -- total lunar eclipses I think they're absolutely beautiful. What's happened tonight is that the mood in the lineup it just right angled pass to the shadow of the -- And that's gonna block the sun's -- from reaching the moon. Actually see the Earth's shadow creek across the full -- Now at the deepest part of the eclipse the moon does action look -- it really cuts. But we caught justice this happening because the -- like it's reaching the moon isn't just some light bending through the Earth's atmosphere. And this isn't the sunset is way ahead the Earth's atmosphere scatters away blue light but let's red light through. So all of the sun rises and sunsets around the earth that red light is reaching the moon and bouncing off it. And I think it's absolutely beautiful to how often -- something like this happen. Well as -- -- should we haven't had a total lunar eclipse visible from North America for a few years now. Now there have been others they're visible and other parts of the world. So well this is really wonderfully fortunate for -- it's it's durable all the way across North America and for some reason you miss it tonight there's also another one coming up in October -- -- OK all right so we'll -- caller's case we have submitted due tonight but if in fact we can now. This is part of a series called -- -- -- what -- is that. So what the lunar eclipse is the angle has to be just right. You see the sun is actually project and the shadow of the earth. And the moon orbits the earth in a bit of -- inclined angle and and -- is that shadow and sometimes it lines up just right. So just tend to come and seasons -- tend to get more than one at a time. And in this case north America's especially lucky because were in for four within the next eighteen months. Pretty -- who brought by the Mets got to after having even have a dry stuff that's the funny little action -- -- so what parts of the country than what were -- or North America would deal the best viewing. The wonderful thing is that this is all the way across North America -- doesn't you on the East Coast tonight the selection start about 2 o'clock in the morning. And that he want to see that beautiful red movement. It will be -- -- -- about 3:45. AM so -- public and the setting my alarm clock for about 3 in the morning get a cup of coffee. And then buyout by 30 in the morning it'll be back to be peaceful mood again everything look back to normal. So this -- -- kind of a fun maybe -- less scientific angle all of this is that these lyric that is oftentimes. Have been tied to calamitous events. The end of the world a lot of these kind of doomsday predictions why is that what is our fascination. With these kinds of cosmic occurrences. Some years ago people thought of space is being very and changing very terminal. And so when something was different you know it it does seem kind of frightening. -- argued that the sun goes away during a solar eclipse a balloon entered -- and -- -- owner clips. But hope for several thousand years now we haven't really been bothered by this we do understand what's going on. An -- the -- Greeks 2300 years ago. -- lunar eclipses to calculate the correct science and a distribution -- -- system. That she proved the sun was in the middle of the solar system that long ago just by looking at lunar eclipses -- have been wonderful scientific resource is as well. So we're really hit some great shots and a for some kids that's a good excuse to stay up late or at least you know set the alarm as bad as you and the -- -- -- be doing as well. But scientifically the what do we still learning about these lunar eclipse is when they do occur. These days isn't much new -- of the lunar eclipse but it sure I think to really appreciate the beauty of the cosmos and think about the -- With satellite -- the lunar reconnaissance orbiter that is returning gorgeous images of the noon all the time. And us this the features on the moon really impressed me this is that a crater Tyoka in the middle of -- there's a mountain and if you noticed a sort of a lit up boulder at the very top of that mountain the -- lighting it up. That boulder is as big as a huge football stadium. So that the scale of the mountains the -- of the landscape. Every time you take these images as scientists we ask ourselves how did become that way how -- the moon -- how to evolve over time. So there's so much more to discover about the noon LRO was recording that there's more water or ice in the soil and we had expected some would there's a lot -- left to learn. -- -- and -- ends and we can also maybe pick up some lessons about Mars correct from these lunar eclipses. You know there's so learn about Mars that we're actually doing in many different ways -- -- -- we have the with the Mars -- we we just launched may even. Which is -- mission to actually study the atmosphere of Mars now that's changed over time. -- doesn't really give us a chance to study Mars but I would say Mars is very bright because it's very close to the earth right now so when the windows dark Mars I think look all the more brighter to us in the sky tonight a beautiful chance to need to do -- -- aster photography -- look at -- through a telescope. Something that -- authority set the alarm very early doctor Michelle Fowler at the Goddard Space Flight Center in Greene a Maryland go get and -- you can have a very early. And that fund viewing of that -- -- -- as well. Thanks appreciate that of course you can keep up with this story in real time by downloading ABC news out starring this story for exclusive updates on the go and look to the skies early Tuesday morning so you don't miss that rare sight of that blood. For now though I'm -- -- New York.
