>> all i saw was a few seconds of the meteor going by. didn't really leave a trail but it was really bright. >> all right so let's talk about it in studio. our chief meteorologist dan henry, the science guy and u.t. arlington astronomer lavont, both with us you. thank you, gentlemen, for offing your expertise. dan, let me -- offering your expertise. dan, let me start with you. this thing, unusual occurrence? >> no. this happens all the time. we just don't see it sometimes they happen but they're less bright. they may happen during the daylight. if you look at the globe as a whole, over 70% of the earth is covered by water, much of it uninhabited. >> mostly happens over water? >> yeah. we see these things and there are no people living there to actually witness it. >> lavont, where did it come from you suppose? space, i guess but do we know? >> particularly there's a lot of space debris out there, and earth is moving all the time. every day. every movement. and space debris, too. sometimes they collide. but we havour air surrounding our earth and predicting us, actually, -- protecting us, actually from the impact because air burns it. it came from space. it was probably i would gues guess -- i don't think it was a very big object though. um -- >> i want to just tell our viewers, we're working on the microphone. it's a little hard to hear. we can hear you through mine but your microphone is acting up a bit. i think we might have it now. >> ok. >> ok so now there's been some -- nasa thinks this was as big as a bus or a car or a truck? you don't agree with that? just a probability? yeah. yeah. >> to me, from the -- from my testimonials, if it was a size or a car or a school bus let's say, at the time the people see it, then that would actually make a crater impact on the ground. but some have said it was -- at one point it was maybe a size of a car before it entered the atmosphere describe and it degrades, right? burns off. >> yes. -- atmosphere. >> and it degrades, right? burns off? >> yes, they travel fast. they travel at 6,000 miles per hour speeds. and at that speed, they may burn off completely. they may break into pieces, or they may make it to the ground. >> if it made it to the ground the size of a bus, we would know because there'd be a big cratener east texas. dan, another thing we talked about -- crater in east texas. dan, another thing we talked about was a sonic boom thing. >> the e-mails and phone calls i got, folks described this meteor this fireball going across the sky and then perhaps, you know, two, three, as many as four or five minutes later, we heard a sonic boom and, um, kind of like the science of meteorologist, there are still things that we don't know, for instance, about tornado formation. you made an interesting point. we don't know exactly, precisely why in some cases like this there's a sonic boom after these things explode in the atmosphere. >> that's true. a lot of people reported sonic booms and also scientists confirmed their existence. but one nasa scientist explained it as it may be a meteor moving in the air it may be a lot of static charge and li a lightning bolt, static charge may be just releasing its energy through bushes and plants. that may create sound. we're not sure about that. >> we joked about that earlier. that's the picture the scientists want. the lightning bolt coming off of this fireball impacting and making the sonic boom noise. quickly, we have to go. what might people find the particles of this thing? i don't know. have you taken a look at the track? >> kind of like probably finding a need until a haystack, i would imagine. >> it may not be possible to find because it may be too small. if anything, fall on the ground or it may be completely evaporated. we don't know but i'm sure to my planetarium, i'll get a lot of people showing up with rocks. >> i know it is. >> it may be very difficult though. >> this is not the typical thing because the earth actually gets 40 tons of space debris every day. that -- collected altogether, that would make the weight of two 18-wheelers. >> don't freak out. happens all the time. thank you, dan henry and -- >> i'll be looking at it. for the rocks! >>
