Odd planet's extreme global warming: Highs of 2240

A study published in the latest issue of Nature indicates there is a distant planet -- HD 80606b -- which is four times the size of Jupiter and is able to heat up more than 1,200 degrees in just six hours.

"We watched the development of one of the fiercest storms in the galaxy," Lick Observatory astronomer Greg Laughlin said in a statement.  "If you could float above the clouds of this planet, you'd see its sun growing larger and larger at faster and faster rates, increasing in brightness by almost a factor of 1,000."

The NASA Spitzer Space Telescope was used to study the changing weather on HD 80606b -- a first for a planet outside of our solar system. It also has a very distinct orbit, as it comes closer to its sun than Mercury's distance from the Earth's sun, before launching away to be just as far as Earth is from the sun.

When it's closest to the sun, radiation is 800 times stronger than when it is orbiting far away from the sun.  The planet orbits the star in 111 days.  The extremely high heat and severe temperature changes obviously make it unlikely any signs of life exist on the planet.

"The orbit is extremely eccentric," Laughlin said in the NASA statement.  "Of the expolanets that have been detected -- we've observed 300 -- this is the most extreme orbit we've seen so far."

The odd orbit accounts for the planet's extreme temperature change, with the planet normally averaging a temperature around 980 degrees.

Astronomers look forward to learning more about the planet, especially its odd orbit that causes extreme temperature changes.  They also want to try and get a direct image of the planet sometime in the future, and leave behind artist's interpretations.

Nevermind the rediculous amount of pressure and gravity on a planet this massive...

I bet if there is life on something like this it would have to have a crazy dormant period during its planet's/moon's solar revolution.

This bad boy tops the list, but it seems like several of the new planets we are finding have fairly eccentric orbits

Actually gravity and pressure are speculative. Remember for constant density, gravity at the surface of a planet goes like M/r^2. M itself goes like (density)*r^3 [some geometric factors like 4/3 Pi are here as well]. So, for constant density, it is clear that a bigger planet will have higher gravity. But consider if the planet is one fourth as dense as Jupiter. It says this planet is 4x larger than Jupiter; so in this case it would have the same gravity as Jupiter. My point is that even in the simplest case of constant density (which is not true since cores tend to be much denser), you can't know the gravitational acceleration of a planet until you know its density.

As far as pressure goes, this is a proprety of the atmosphere above it. With so little protection from its sun, I would venture a guess and say it has a thin atmosphere.

Also if you consider evolution you'll realize that life generally begins as single celled organisms. If the gravity is so extreme that even these die then there's no hope of life. But if these can thrive, then larger creatures should evolve but would do so in a way so as to withstand the gravity. Humans are very well designed for g=9.8m/s^2 or so. When we get placed on the moon with a gravity of around 1.5m/s^2 we don't work very well -- bouncy, hard to walk, etc. On higher gravity planets we would probably be shorter and break more bones; we also would die from shorter falls.

I see what you're saying. Still, even if it was made up of 100% hydrogen, it would still have at least hundreds of times earth's gravity and pressure, no?

The "atmosphere above it" as you put it is most proportionate to the total mass of the planet. As close as it gets to its sun, im sure some of the atmosphere is lost, but I it would aslo steal back a fair bit of matter from the star.

That is Carbon based life forms, there "could" be other life-forms which aren't carbon based like what we have on earth, something like a Sulfur based life form would be a completely different kettle of fish, where we wont be able to predict it's requirements to sustain it's own life.

The issue is that we are looking for "Carbon" based life forms, if the universe is infinite, and if Aliens exist, there would be more variations.

There could be other life forms which aren't carbon based, anything is possible. But in reality, not probable. The reason why all known life is carbon based is not necessarily because earth is unique, but because of the special properties of the carbon atom that make IT unique, like the fact the they contain 4 valence electrons, that it can form bonds with itself and that it can readily form bonds with other organic elements like hydrogen, nitrogen, and oxygen.

My guess is that whereever we find life outside of our planet (most likely outside of our solar system) they'll be carbon based. Physics and chemistry are universal, so my hunch is that it doesn't matter where in the universe we may find life, it will be similar to life on earth in the sense that it will be carbon based, it will contain organic molecules, and it will thrive in similar conditions as life does here on earth.

My 2 cents.

I remember reading somewhere that on a planet with a high natural temperature, that it would be more likely to evolve Silicon based life forms. Apparently these lifeforms would be more well suited to stand up against higher gravity forces and heat.

Unfortunately, while it seems silicon is chemically very similar to carbon, it has a fatal flaw which makes it different, and thus unsuitable for the basis of life.

Excerpt from website http://www.daviddarling.info/encyclopedia/S/silico...

quote:
When carbon is oxidized during the respiratory process of a terrestrial organism, it becomes the gas carbon dioxide – a waste material that is easy for a creature to remove from its body. The oxidation of silicon, however, yields a solid because, immediately upon formation, silicon dioxide organizes itself into a lattice in which each silicon atom is surrounded by four oxygens. Disposing of such a substance would pose a major respiratory challenge.

quote:
Life-forms must also be able to collect, store, and utilize energy from their environment. In carbon-based biota, the basic energy storage compounds are carbohydrates in which the carbon atoms are linked by single bonds into a chain. A carbohydrate is oxidized to release energy (and the waste products water and carbon dioxide) in a series of controlled steps using enzymes. These enzymes are large, complex molecules (see proteins) which catalyze specific reactions because of their shape and "handedness." A feature of carbon chemistry is that many of its compounds can take right and left forms, and it is this handedness, or chirality, that gives enzymes their ability to recognize and regulate a huge variety of processes in the body. Silicon's failure to give rise to many compounds that display handedness makes it hard to see how it could serve as the basis for the many interconnected chains of reactions needed to support life.

quote:
The absence of silicon-based biology, or even silicon-based prebiotic chemicals, is also suggested by astronomical evidence. Wherever astronomers have looked – in meteorites, in comets, in the atmospheres of the giant planets, in the interstellar medium, and in the outer layers of cool stars – they have found molecules of oxidized silicon (silicon dioxide and silicates) but no substances such as silanes or silicones which might be the precursors of a silicon biochemistry.


That's not to say we won't find artificial "electronic" life based on silicon, but it seems physically and chemically impossible for biological life to be based on silicon.

If I remember correctly Jupiter is on the upper end of what size a gas giant can achieve. Increased mass will just increase density and at about 10 Jupiter masses it will ignite into a brown dwarf.

The force between two objects due to gravity is proportional to mass. You only need the density by virtue of the fact you can work out the mass from it... if you also know the size.

something about problems with constantly overheating.

ATI has released a statement stating, "We are looking into the inquiries about our HD80606b series experiencing extreme heatsink failures when specific applications are launched. We seem to have...misplaced our data on the HD80606b series, but we assure our customers that we stand by the quality of our products and will work around the clock to address the problem and to fix it via firmware update as soon as we can figure out what an HD80606b is.

What's a degree?

For the record, 1200/980 degrees is meaningless; degrees what?

I realize that Fahrenheit was indicated in the title, and so a moderately intelligent gerbil could infer that Fahrenheit is used throughout the article, but it's still kind of lazy not to throw an "F" or other indicator into the text.

The original article had temperatures in Kelvin (with F equivalents included for the non-scientific reader). Why did the post on DT omit the much more meaningful Kelvin temperatures. Besides, for everyday usage, it is a lot easier to convert temperatures from Kelvin to Celsius, than it is to convert Fahrenheit to Celsius.

(n) sun (any star around which a planetary system revolves)

While our sun does not have a proper scientific name it is referred to as the Sun or also Sol (hence Solar System). Other planetary systems would have their own unique star but one can refer to other stars as the sun of planet xyz. For example, the star Gliese 581 can be referred to as the sun of Gliese 581 d, the third planet in that planetary system.

As you are saying, I believe Sol is the 'name' of our sun. Of course Sol means sun in Spanish.

Similarly our moon is named Luna but we all call it 'the moon'. There are plenty of moons out there. Just like how there are billions of 'moms' out there, but if someone is talking about their mom, they are only describing one person.

Nah, sun in lowercase refers to the nearest star to a given object. The uppercase Sun refers to Earth's sun.

It's kind of like god vs God. The first is a generalized creator, whereas the latter is the Christian god.

While the relative importance and magnitude of both contributions WRT climate change is an interesting and important debate, I'm very, very tired of seeing useless broadsides like this in every article that even remotely relates to the subject.

I'm not taking a side on the man made part of global warming but I'll go ahead and say your particular argument is flawed.

The albedo of Mars is changing fairly proportionate to it's temperature. Not so on Earth.

Also, neither are falling into the Sun.
