Coldest Star Found—No Hotter Than Fresh Coffee- STARS WITH WATER!!

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. (Related: "Dimmest Stars in Universe Spotted?")

"Over the years there has been steady but slow progress in pushing the boundaries of finding the coldest stars," said study leader Michael Liu, an astronomer at the University of Hawaii.

"But with this latest discovery we have made a big leap forward—besting the previous record holder by at least 150 Kelvin [270 degrees F, or 150 degrees C]," he said.

Coldest Star May Have Watery Atmosphere?

With an estimated mass of only 6 to 15 times that of Jupiter, CFBDSIR 1458 10b is the smaller and dimmer member of a binary system in which two brown dwarfs are locked in close orbit.

Liu and his team spotted the pair's faint infrared signature using the W.M. Keck Observatory and the Canada-France-Hawaii Telescope, both on the summit of Mauna Kea in Hawaii.

The discovery is stretching our understanding of where to draw the line between what is a planet and what is a star, Lui added. (Related: "'Super Earth' May Really Be New Planet Type: Super-Io.")

For instance, although surface temperatures on our solar system's Jupiter sit around -236 degrees F (-149 degrees C), astronomers have found so-called hot Jupiters orbiting other stars with surface temperatures around 1,000 degrees F (538 degrees C).

In star terms, "this new object is so much colder than anything else seen that it now enters the regime where it may actually have an atmosphere with water clouds," Liu said. (Related: "First Proof of Wet 'Hot Jupiter' Outside Solar System.")

This is awesome news, I'd love to see what the surface looks like.

Maybe this will happen to Earth soon

It really just goes to show how little we know about our universe. Nothing is written in stone. Before this article, if someone said "Its a possiblity that water exists on stars" you would have got attacked, called names, and laughed at. The world is not flat....anyone??

This is actually where Starbucks came from.

I can just imagine a mineral shine surface from old processed elements from the old Star phase it was in. And te water who knows the properties and abilities within it.

Thanks

Yes it does appear we are ALL still learning, even scientist. I wonder if there are any other planets that used to be stars.

Thanks

Great find man S&F for proving we don't "know it all"

reply to post by Artorius


Thanks Artorius, it would be nice to have a nice listing of all stars and how they work their influences. But 1 feels thats too much data even for some of the most advanced potentials out there. And they may all be unique..

Your welcome bro. This thread should be buzzing Maybe change the caption to "THE WORLD IS ENDING PROOF HERE!!! coldest star found with water THE WORLD IS ENDING PROOF HERE!!!"

That explains the burned taste.

OT:

A Star that burns at 200 degrees F is an impressive find. I wonder how they found it... The mean temperature of the galactic neighborhood is cold, but it is filled with hot stars and gases in the millions of degrees.

LOL, Yea it is an interesting topic but unfortunately some get vibes from me sometimes like im on some ole evol stuff because they cannot fully understand me, so at least they still scan and get the data and that's all that I try to do. It is only 75 light years away. Its nice to get the Stars and Flags yes but my main objective with ATS is Earth education and beyond understanding.

Be well.

The Earth as a shining star, is a beautiful thought.

One thing that I keep on thinking of is how do we know what we are looking at e.g. how do we know they are natural and not artificial ..... mankind is like an amoeba compared to the alleged civilisations out there that would have massively advanced technology to us

reply to post by blackcat99


It is hard to tell if its all artificial, but it is still part of the current reality many are used too. Especially if within simulator boundries its still reality somewhat. 1 day the reality of it all will be understood but for now we must master this artificial zone and all it offers, if artificial glitches may exist..
Thanks

If, as the article suggests, it is basically a "failed star" with insufficient gravity/mass to start internal stellar
nuclear fusion. How is the small amount of heat (206°F) that it has being generated ?
Logic would suggest that the temperature would be similar to Jupiter at -236°F or so.
Residual heat from original formation ?
Any thoughts ?

I feel its maintaining its cooler temps do to its binary partner possibly absorbing large amounts of its energy related to Heat from when the star was dying and being reborn into its current state. This would inturn prevent this star or advanced star from maintaining all of its heat signature. I would imagine the partner star is a hot one but havent researched to be sure. But I do think its due to its partner being more greedy with the heat absorbsion. Again I am no scientist but is what I think.
Thanks

Awesome News! S&F!
Thanks!

A Brown Dwarf with an atmosphere and water vapor clouds?

LIFE?

reply to post by Noromyxo


It's mass was stated to be as much as 16 times what Jupiter's mass is. However, Jupiter has sufficient mass to generate enough heat for a sea of a liquid metallic hydrogen interior to reach temperatures of 10,000 kelvin deep into it's gravitational pull. Which brings to mind, exactly where do they determine 'the surface' to be? Our Galileo space probe was descending into the Galilean atmosphere for nearly an hour before it was vaporized by what it transmitted to be pressure of 23 atmosphere's on earth, at a temperature over 300º F.

It's the cloud tops of Jupiter that is measured at being around -150º F.

The star with the most gravity, mass, not necessarily size, wins the fuel battle in a binary system, of at least one spent star, or a star of insufficient mass to conduct fusion.

They didn't really explain watery atmosphere very well, hydrogen and oxygen are the two most abundant elements in the universe. They make a leap there just a bit but never stated it's actually water, because it's not boiling temperature, and sufficient mass to contain the elements, and not lose it all to space.
