HOT PLANET DISCOVERY (STSci)
New observations by the Hubble Space Telescope's Cosmic Origins Spectrograph (COS), confirm the existence of a giant scorched extrasolar planet traveling extremely close to its star. Named HD 209458b, it's being called by astronomers a "cometary planet" because it has the components of a planet - but with a trailing tail like a comet, possibly the result of strong stellar winds sweeping off its super heated atmosphere.
Eric Smith: "Mass is being stripped of at the rate of about 100,000 cars per second. So, a typical big car plant on the Earth might make 100, 200, 300-thousand cars a year. That's how many they're making. This planet's losing that much mass per second."
HD 209458B is 153 light years from Earth, weighs slightly less than Jupiter, and speeds around its star in about 3 and1/12 days, which means one of our weeks is equal to two of its years.
Eric Smith: "Up to just recently in human history we've only known about the planets in our own solar system, and can study those and so we developed theories about how stars and planets formed based upon that. Now, there is just this incredible diversity of planet types, different stellar types, different orbits, and it's causing us to have to rethink entirely how we believe stars and planets formed."

im loving the new nasa vid" look" a litle bit vintage with new news ,great
This is why I sub to ScienceMagazine: that little shot of optimistic awesomeness every other day!
That's totally awesome.
So cool !!
Muy interesante.
@julsHz Well said thank you for the specs. I always wondered what a naked Jupiter would look like. wow that came out wrong, lol
@HongKongGhost I may be mistaken, but I believe it was about 0.3 movie seasons ago.
@Kranda123 LMFAO WHAT?
@julsHz I wonder if it is molten mass from the planet or gas from around the planet.
mass, cars, hot planets???? Dont ya just love science :-)
When did we start measuring mass in cars?
@Buzzlybonk
Thanks for the insight, looks like I need an upgrade.. Old Theories past their sell by date ha ha!
Cool, for some. Admittingly it's hard for me to care, but the more we learn the more we know, even if some facts fail to fascinate.
@HongKongGhost It's for a general audience; most people I suppose can visualize a car better than some abstract measurement in a weight they might not have heard of.
I'm curious to know how a planet like that formed. If it loses that much mass per second, how did it form in the first place? Maybe it formed further away from the star, and it is on a spiral orbit with the star?
@DackIsBack By far the best comment here.
"Mass in cars" truly shows there's something wrong going on with NASA. :P
soon or later, we're gonna find a planet that harbors life... when will it be?
@TheBigMclargehuge it is probably easier with the car analogy as 100000 cars probably only represents 0.00000000000000000000000001% the mass of Jupiter.
@firewallx I could be wrong but the only reason they can tell there is a planet there is bcause of it's parent star's wobble, iow there aren't any pictures to show:(
@Kossimer I can imagine the size of one car, three cars. But 100000 doesn't help.
@HongKongGhost We started measuring mass in cars as one more step above measuring speed by horses. Horse power, ya know? (pun intended).
@CO2Junkie
Thank you.
What I meant was that, though the US has the smartest people around, the American public as a whole is on the level of elementary students. Everything has to be labeled, so that thinkerboxes don't hurt, and so that no-one is offended or left out of the loop. That was the point I was driving.
The people who do these clips should trust that their audience has some basic understanding how to do things; not make things so that even simpletons understand. It is insulting.
@commerceskate
Is it?
I've always heard reports that were being drawn towards the Suns Gravity?
I know the Moon is moving away from Earth's Gravitational Pull.. I must go on a knowledge hunt.
Thanks for the info.
@CO2Junkie
I do subscribe a monthly science magazine. To me the vids are merely to inform that something has been found. If I find the subject interesting, I read further.
This is probably happening to our planet as well.. The Gravity of the Sun pulling us in.
@CO2Junkie
contd.
Even though I admit that some of this material IS meant for elementary students, they are often too simplified. E.g. counting mass in cars? Who came up with that?
They should trust their audience to understand things without resorting to neighbourhood analogies and hand-puppets.
Let's colonize it!! XD
Better idea, let's let creationists colonize it!!
@robertwc82
"so you can accurately visualise any measurement in your head?"
I didn't visualize it in my head, I did the math..
We should start shedding cars also, we have too many and the fumes make it hard to breath in cities
100000 cars? How much is that in elefants (which are a way better unit for mass)?
I also didn't get the distance. At how many football fields is the planet orbiting it's star?
@settlefornothink
You would think he's explaining it to a bunch of WOW players, huh?
@crazylegoguys my math is solid dont question it.
@Farf420 how the f@#* do you caluclate that
haha who names these planets. call it bruce
@CO2Junkie
I'm from the most internet-oriented land on earth.
And typing w w w is basically default when it comes to internet use. Firefox and other browsers AFAIK add the dubyas if it is the only option that fits. Try on your browser just typing nasa.gov. Go ahead, see that I'm right.
oh cmon guys he's just trying to put the mass in context, if you say "10 billion lbs per second" you don't really get the idea.. Go watch penn and teller's numbers.
@commerceskate
Gives us a chance of a good tan. ;-)
Stripped off by 100,000 cars per second A full on double scorched planet! It's almost a triple scorched planet! OMG. What does this mean!
ONE HUNDRED-THOUSAND CARS!!!!!!
@tommytalks77 generalization is your first mistake - you should be smart enough to know that the average is only average and that there will alwayz be those who give any category a bad name and then there will all be those who stand out from the crowd
Whats with the cheesy music? Its hard to enough to show the plebs that science is cool ... the cool facts speak for themselves, no need to make it sound like a cheesy infomercial
And are the cars the Gas Giant is shedding Impalas? or the smart and stylish Chevy Aveo Sedan,with better fuel economy than a Hyundai Accent? Scientists speculate that the next generation of telescopes will be able to detect planets that shed Hybrid vehicles, but there is no hope of detecting planets that shed beanie babies, pop tarts or dental floss without some sort of technological breakthrough.
@brianl9944 Most of us have found one allready! :)
{"rethink entirely how we believe stars and planets formed"}
I don't see why it must be such a mystery. Anybody being simply of average intelligence & degree of scientific knowledge, should realize that the answer is scientifically elementary... obviously, they formed in the complete absence of Entropy... how else?
@Tounushi - I'm not doubting that you're right. I was wondering why the prejudice against a whole nation :D
And I think I've come across some instances when putting in the w w w after the h t t p actually caused a problem for locating the site. But that's me. Maybe it was an old browser.... and now we're off the topic of the video. So take the last word if it makes you feel better.
I only use units of Eiffel Tower masses per hour...anyone know the calculation?
@settlefornothink You do realize that NASA is an American organization, and the scientist featured was probably American? Not everyone is familiar with the metric system or the american system, but almost everyone can easily imagine the size of a car. That would be the reason for it.
herp derp cars
@Farf420
Man, stop being so unscientific. You know that for such huge numbers we don't use paper clips, we measure it in the big office paper clips, which surely would be 4157217156
@JesterAzazel how did you cheat?
@CO2Junkie
I have no training in medicine (beyond battlefield first-aid), so curing cancer would not be up to me.
The car analogy is too nebulous to function well. Do the mean small peugeuts or huge humvees? Why not use some other well-established heavy object with little ambiguity? Such as a large liquid container (e.g. barrel, tanker, etc.).
Or how'bout just give a straight tonnage.
@dbx2soha lol, and you can picture 100 000 cars in your head? it makes no difference, cars, grams, if its not a number you can count on your fingers and toes you wont be able to picture it
"w w w"
Really? Still with w w w? And this is coming from NASA, no less.
I'm surprised he didn't finish that line with "via the Interwebs".
its a tiny DOOMED planet ..
@settlefornothink so you can accurately visualise any measurement in your head?
tell me how many sqaure metres would 3489 tons of golf balls cover?
.....yeah thats what i thought!
@commerceskate How about a brazilian, who's lived in the IUS for a while, went to school there, and also who lived in a few countries in Europe for almost a decade? Am I a stereotypical brazilian if I too say that americans do need to have things dumbed down for them in order for them to half understand it?
Sorry mate, but compared to an average european, the average american is like a door...
To put their numbers in a better perspective, think of it this way. A car is equal to about 1000 bicycles and a bicycle is equal to about 4 unicyles and a unicyle is equal to about 100,000 paper clips. So the planet is losing about 12098414981234190234812391823492394823904202412894398234234.234934 paper clips a second!!!
saying "dubya dubya dubya" is very redundant these days..
Just say nasa.gov, and ppl will find it.
OH, I forget, this is for the usual american audience. And they have to be walked hand-in-hand through everything. Please...
the sun is the most hottest planet ever but Jupiter is was equally to hot to the solar system the sun began to make more more sun like hot species ever....
@Tounushi - Why hate on Americans? What population of above average primate are you from?
Anyway... doesn't w w w & h t t p sometimes give different results? Walk me through it, oh great oracle.
@Tounushi - You ever heard of an IQ curve? A standard distribution? What would be so horribly wrong with dumbing something down as to make it informative to a larger segment of society?
If you're such a genius - AGAIN I ASK YOU - WHY ARE YOU GETTING INFO ON UA-cam? Go pick up a current peer-reviewed journal on astronomy or physics. Go work on publishing your latest research... or just go. Go go go, away.
I have other sheep, which are not of this fold; I must bring them also, and they will hear My voice; and they will become one flock with one shepherd. John 10:16
Now we know why Jesus hasn't been around; he is probably collecting sheep on other planets.
