According to a new study, a star discovered 75 light-years away is no warmer than a freshly brewed cup of coffee.

Dubbed CFBDSIR 1458 10b, the star is what's called a brown dwarf. These oddball objects are often called failed stars, because they have starlike heat and chemical properties but don't have enough mass for the crush of gravity to ignite nuclear fusion at their cores.

With surface temperatures hovering around 206 degrees F (97 degrees C), the newfound star is the coldest brown dwarf seen to date.

If this was already posted sorry.

This is pretty damn cool, no pun intended(because that would be retarded). That shit's big enough to vaporize all the bud in the world at once. Safe stoning for all!
 
That is pretty crazy! I wonder if we discovered this brown dwarf at the very end of its life-cycle. Literally as the last remaining entropy dissipates. speaking of which, i looked around and must be crazy but isnt enthropy considered the amount of heat in an system and entropy the amount of dis-order in a system?


all i found was that Entropy is both? lol my IB chem 2&3 teacher was wrong! lol..or maybe just my memory. %)

Brown dwarfs don't really have a life cycle; they simply cool over billions of years at a rate inversely proportional to their mass. This could be an old but massive brown dwarf, but more likely it's a young, low-mass, quickly-cooling example.

Enthalpy is what you are thinking about. Entropy is the trend towards the lowest energy state (equilibrium within an isolated system) which also happens to be the least ordered.

no you're right, however i was more talking about the entire life cycle of a star itself even though this particular brown dwarf never actually achieved Star status as we classify it today. either way its an astonishing observation from something that we normally think about as completely inhospitable and a complete conflagration. however, just as i typed that i thought about the idea of life existing ON this dwarf star due to its lower temerature. I wonder if thats possible? Im not sure what kind of radiation brown dwarfs emit...except for limited infrared in this case.

Oh, and Shimmer im pretty sure your spot on. Its been years since i was in a physics or chemistry classroom and i think its about time i go back to the community college for a brush up on my sciences. :)
