Dying Star Mimics Our Sun's Death

kdawson posted more than 4 years ago | from the telltale-heart dept.

Space 149

coondoggie writes "In about 5 billion years, our Sun will face a nasty death. Scientists with the Harvard-Smithsonian Center for Astrophysics this week released dramatic new pictures of a dying star much like the Sun, about 550 light-years from Earth. According to the researchers, Chi Cygni has swollen in size to become a red giant star so large that if it were in our solar system it would swallow every planet out to Mars and cook the asteroid belt. The star has started to pulse dramatically, beating like a giant heart with a period of 408 days." The research team produced a video of the pulsating star, using infrared images captured via very long baseline interferometry.

iamacat (583406) | more than 4 years ago | (#30454892)

We'll be long gone - either in spacial or temporal sense - in a tiny fraction of that time. Even if there are no asteroid impact, killer viruses and so on, we will eventually deplete all natural resources - including ones need to make solar cells and wind turbines - and release enough long-lasting pollutants to make life unsustainable. So, an interesting astronomical curiosity, but no impact on our distant descendants. Now lets go work on being gone spacialy.

Huh? I might buy that we could kill ourselves off but it seems to be giving us too much credit to assume that we could kill off all life on this rock. Life has been around in one form or another for billions of years and has survived far more cataclysmic events than anything we could ever hope to dish out.

Disagree. I think a small human population (in the millions) will be around on Earth to witness the event.
    I don't think the planet will be healthy enough for 7 billion of us, but I also don't think it will be poisoned enough to drop the population to 0 before Sol expires.
    I also think we'll be content in sending bacteria to other worlds rather than humans - they are a much more resilient and adaptable species really - humans are too dependent on a tight range of environmental conditions to live in other worlds, we just need to make the best of what we have here.

Even if - there won't be much difference in relation to current faiths (assuming also that there would be any humans left - those are two immense "if"). Just look at our historical record - mythologies don't survive even few thousands years, even when we do have good record of them.

They are just becoming fairytales for adherents of mythologies prevalent at given time (little do they realize that it will be the same with theirs...)

Add to the above that we have no way of determining the state, type of society or even consciousness 5 billion years from now - but it will be most certainly quite alien, not easily falling under our criteria.

Re:Do we care? (2, Insightful)

sznupi (719324) | more than 4 years ago | (#30455242)

I think you have a hard time (as all of us do) imagining the time periods involved. There was even no mammals 1/10th of that 5 billion years ago; heck, life hadn't really colonized land yet.

And anyway, the Sun is slowly becoming brighter as time passes; in around 1 billion years theere will be no oceans left on Earth, no biosphere.

Re:Do we care? (4, Informative)

mrsquid0 (1335303) | more than 4 years ago | (#30455928)

The Sun is slowly getting hotter (over timescales of hundreds of millions of years) due to changes in the composition of its core. In about one billion years this increase in temperature will be enough to have boiled off Earth's oceans making Earth a dead planet. This will happen long before the Sun becomes a red giant, so unfortunately there will be no humans around to witness it, unless if we leave first and pay a visit to watch Sol's demise.

Re:Do we care? (2, Informative)

Anonymous Coward | more than 4 years ago | (#30456214)

I don't think the future humans will call themselves homo sapiens sapiens within a half a million years, let alone few billion. Whatever the species will be which will witness the event form sufficient distance, they need to be able to live past the event for it to have some significance.
Our beloved Milky Way will collide with the Andromeda in about 2 billion years like an intergalactic ejaculation. If the Earth has not been sterilized by asteroids by then, perhaps the radiation resulting from the collision will finish the job.

Re:Do we care? (0)

Anonymous Coward | more than 4 years ago | (#30455110)

I don't see why we would be gone. Even after our sun goes boom, provided we manage to get some of ourselves off this rock on a permanent basis, parts of our solar system will still be livable, such as some of the moons of the gas giants, floating cities in the atmosphere of the gas giants at an elevation where the air pressure is one atmosphere (Jupiters surface gravity is 2 1/2 times ours which would be a problem for normal humans, but for Saturn and Uranus the surface gravity is actually slightly less than that of Earth and Neptunes is about 10% more than Earth, so there's not much of a problem there), any of the hundreds or thousands of dwarf planets and other massive objects past Neptune, not to mention any of the millions or billions of artificial human habitats humans could construct in the given time frame, even with current technology if we stopped dithering and got around to it. As for depletion of natural resources, there are plenty out there, the only really important resource is energy, and we'll still be getting lots of that from the sun even after it turns into a red giant. For cases where that isn't true and there's some rare element that we need for some vital purpose, we will probably eventually be able to just make more (at high energy cost) if the need is urgent enough. We've achieved part of the goal of the alchemists and been able to make gold from lead (easier to make gold from platinum though, or lead from gold) for decades now, the costs just aren't worth the returns. To my knowledge, there's no natural barrier to making any element we want even with current technology, it just has to be valuable enough to warrant the massive expenditure.

Yeah, the crime of the modern educational system is that it produces people who know all the answers and have no sense of wonder. That "older than dirt" guy probably looks at a computer and only sees a white box.

You should look at a computer and see the thread of execution hopping between kernel routines and pausing at mutexes. You should see the electrons whooshing through the silicon, underneath an overhanging crystalline gate electrode. You should feel the electric field sucking at you: it's almost strong enough to rip electrons out of the SiO2 dielectric. And back up at higher level, those spin locks should be like an amusement park ride: puke your guts out if you go around in one for more than a few microseconds. :)

Yah, we knew stars became red giants. But that's not the right way to look at it.

Dunbal (464142) | more than 4 years ago | (#30455796)

we humans would destroy the earth lot before by global warming

      Apparently we're going to have to work a lot harder to do that because the Earth has been through (and shrugged off) far worse [liveleak.com] changes than the current one.

      Now consider that along with the fact that recently Dr. Maslowski confirmed that Al Gore was misusing and misquoting data supplied by him to support his political agenda. Consider the mere fact that the push for the idea of "global warming" is coming from the POLITICAL, not the scientific, end of society. Consider the fact that "global warming" has opened up a multi-billion dollar a year "carbon offset" market, and new taxation revenue streams for government.

      There is a motive to convince you that the world is going to end. People are willing to believe the world will end for any reason, from the arrival of comets, to planetary alignments and eclipses, to the "return" of "the son of man" (who is coming soon - any day now...). If politicians start clamoring for it, and misuse scientific data to "back up" their claims, there are any number of sheep who will bleat to that tune. To the point where people are already turning violent at "protests" - which can only represent a certain degree of fanaticism about the subject. But simply believing something to be true DOES NOT MAKE IT TRUE.

      Still, don't worry. The oil won't last forever. In fact, once we reach peak oil, its availability will diminish dramatically due to exorbitant prices (look what happened when oil reached a mere $150/bbl, now imagine it at $1500/bbl) as countries compete for the last drops of oil and society has NO CHOICE but to switch to alternative energy. Since the Earth has already demonstrated that it has returned from far worse temperatures/CO2 levels than today, even if global warming was "man-made", the Earth will purge itself of "our pollution" in a few hundred years once we stop "polluting the atmosphere with our CO2".

      However if it's not man-made, well, temperatures are going to rise even when the oil is gone. That will have a lot of people scratching their heads and wondering why they're paying all those carbon taxes in 100 years or so, when oil production/consumption is diminished or negligible. And they will stay at their peak for a hundred years or so. I can imagine some politicians in the far future patting themselves on the back when temperatures return to normal...

Re:Worst case (3, Interesting)

francium de neobie (590783) | more than 4 years ago | (#30455196)

Again, what's up with the negativity?

First, why would other intelligent life bother to stop us? Because resources in the universe is scarce? Last time I checked we haven't discovered any Dyson Sphere built around any of the stars in the Milky Way. And why has nobody scooped up all the intergalactic medium in outer space? Have our telescopes seen anybody moving stars around for energy transport? People using the beam from active galactic nuclei as weapons? No? If those ultra-intelligent life are really as good as they're hyped up to be, why aren't we seeing some totally amazing stuff happening all around us?

Second thing, it didn't really take much time for life to appear on Earth on a cosmic timescale. If you look at the time it took for our solar system and life to form, it is actually on the same order of magnitude to the whole history of the whole universe itself [wikipedia.org]. If we're one of the late-comers, shouldn't we find that the universe has formed 1 trillion years ago, our solar system has only formed in the last 5 billion years, and life only in the last 2 billion years? Instead, what we're seeing now is, the universe formed some 13 billion years ago, our solar system formed 9 billion years ago, and life appeared in the last 3.5 billion years [wikipedia.org]. There's actually a pretty decent chance that we're one of the earliest intelligent life in the universe.

You know, if immortality is within reach of my generation, I'm totally looking forward to have an AGN as my toy.

It has nothing to do with TFA but it just occured to me - do we know of any system where the central body is not a star (or a more massive object), for example let's imagine Jupiter in place of the Sun?
Would it be possible to detect this kind of system at all?

Re:Just a thought (1)

Jkasd (1663231) | more than 4 years ago | (#30455734)

In a binary star system, the center of mass could be relatively empty if the stars are close to the same mass. But since gravity is what keeps the whole system together, the most massive object will tend to be in the center. If you somehow switched the sun and Jupiter, the sun would become the new center again, while everything else would chaotically fall back into new orbits around it.

i think what he is trying to say is "what if there was no star in the system?" as in the center of mass would be a large planet like jupiter or maybe a black hole. We would have no way of detecting these unless they some how blocked/warped the light of other known stars

Being that the star is Chi Cygni, I suppose this is its 'swan song'...

Electric Universe (-1)

Anonymous Coward | more than 4 years ago | (#30455812)

In the Electric Universe model this is actually a young unstable star! The reason why it can expand and contract, in a way that seems completely at odds with the broken fusion model, is that it's reacting to the local(galactic) electrical conditions trying to maintain electrical stability by expanding and contracting the surface area of the anode (the photoshphere as we would know it). Our sun is mature and stable and reacts in a more modest way.
A lot of the editorial the goes with images like this mentions plasma, magnetic fields etc, all clues.
Supernovae are when it goes horribly wrong...
It's an interesting theory anyhow, makes our universe a lot less exotic and mysterious but it's still really beautiful!

Baited with title... And no pictures (0)

Anonymous Coward | more than 4 years ago | (#30456230)

Articles like this piss me off. They bait you with a really juicy title like, "Close-Up Photos of Dying Star Show Our Sun's Fate"... And then not only don't have any of these close-up pictures for me to check out, but there's not even a link or sentence that tells me if there's a website I can go to look at them.

Of course, Science Daily is notorious for this.

Disfactual SD FUD (3, Interesting)

DynaSoar (714234) | more than 4 years ago | (#30456452)

The folks at Harvard-Smithsonian and IOTA did some fine work. It could have been reported as they presented it and been very interesting science. When it gets filtered through a fake science reporting agent like Science Daily, and rewritten by one of said agent's fiction writers with only enough relevant background to make them capable of finding FUDish material that wouldn't be entirely inapplicable, the result is something that should have been rejected by the only places to which it should have been submitted: Hollywood movie producers.

The sun is a nearly a dwarf star. It will undergo a very mild death compared to larger stars. They will nova or supernova, but the sun will placidly swell to a red giant, pulse as it burns out, then shrink to white dwarf. Only true dwarf stars will undergo a milder demise, skipping the red giant phase. No amount of mediocre Hollywood scifi horrification and awfulism will change the fact that our mild mannered stellar companion has no evil supervillian alter ego waiting to take over at its end of days. Adding such extraneous comic book (as opposed to the more respectable graphic fiction) "reporting" is only done by a writer, or at the behest of an editor or publisher, who have no confidence in the science itself or their reportage of it being sufficiently interesting. rather than risk being factual for a readership interested in such things, they attempt to draw in a greater audience with an interest and education in science equal to that of the author's writing style, with the assumption that by adding the pseudo-scientific car wreck material they can get that larger audience to slow down and rubber neck at the bloody mess of hyperbole spray painted over the facts.

SD is as useful and accurate a source for science as The Economist, which has also been quoted here for similarly poor reasons. Slashdotters are for the most part sophisticated enough to be able to appreciate the facts without having to viddy the horrorshow while sipping a bit of the moloko plus (obSFref, Clockwork Orange). Th remainder, while not so inclined to factualism in science, are still so invariably capable when it comes to traditional /. reply banter that an article consisting of raw data would likely end up in a verbal tsunami repleat with references to Microsoft, Google and MafIAA (blaming them for the stellar death no doubt) and welcoming our Red Giant Overlords and their Soviet Russian Beowulf Clusters.

The very worst part of this example of poor writing in lieu of science journalism is being kept separate because it has nothing to do with science. Something that is happening now (or being observed now, relatively speaking) does not and can not mimic something that will happen in the future, whether that be in 5 billion years, or next week when you accept a job writing equally badly for an outlet equally unwilling to risk actual factual journalism. Unless, of course, one an say that one's present insufficient income from writing such trash mimics the income one will receive in the future when one continues of a career path of writing badly for outlets intentionally presenting said trash. All the more reason to stay in school, kids, and if you quit, go back.

Now, I don't expect /. readers to follow Astrophysical Journal and the like in order to get unadulterated science to report on here. But I would hope that the submitters and editors would at least acknowledge the quality of the sources by presenting them such as "With their typical crunchy coating of fiction, fact mangling and FUD surrounding a center of creamy scientific nougat still untouched by science journalists' hands, Science Daily reassures us that it is 'an excellent driver' while setting fire to and waving madly an interesting article" dot dot dot.

Lol, you think we really are going to read everything carefully? We are busy people with real jobs; science, IT, etc. If you dont like it go somewhere else. And dont start about getting new editors..this job is a lot harder than one would think and we do a nearly excelelent job at what we do.

I panicked for a moment - I thought it said five million.

The homo sapiens species has only been around roughly 500,000 years [wikipedia.org]. Human civilization, from its absolutely earliest form, has only been around for about 14,000 years. [wikipedia.org]

Even if it said five million, I dont think that would be reason to panic. That's a really, really long time. Although maybe that's the joke you were trying to make, and I'm too dense to get it.

Not very long baseline interferometry (2, Informative)

ogre7299 (229737) | more than 4 years ago | (#30457076)

Just a minor correction. the scientists did use interferometry but it was not "very long baseline interferometry". The "very long" term applies to the telescopes being separated by extreme distances, say over the entire United States as is the case of the VLBA. Also, the VLBA can only function in radio wavelengths because the data can be taken at the individual telescopes an recombined later. With near-infrared interferometry, what the authors of this study were using, requires that the light from each telescope be sent down an optical tube with mirrors and recombined at a central location which constrains the IOTA telescopes to be close together.

IOTA was dismantled a few years ago, geiven that a new optical/near-infrared interferometry was coming online, CHARA http://www.chara.gsu.edu/CHARA/ [gsu.edu]

Re:Not very long baseline interferometry (1)

radtea (464814) | more than 4 years ago | (#30457262)

Thanks for the info! The article was unclear on that, as on much else. I particularly liked that "stars are really far away" was given as the second reason for this kind of imaging being difficult, as if the extreme distances didn't make this sort of thing completely impossible until a decade or so ago.

The video is wonderful, and accounting for the persistent asymmetry in the early expansion phase will no doubt result in a more detailed understanding of the oscillation mechanism of these stars. First rate science, badly mangled as usual by /. and the tabloid science press.

"thin gas" by time sun xpands to earth orbit (2, Interesting)

peter303 (12292) | more than 4 years ago | (#30457312)

A hugely expanded sun would be a hot, tenuous gas by the time it expands to earth orbit. People could acutal live in it with minor protection. But the hot gas would relentlessly erode anything on the earth's surface. And eventually it would corrode away the earth itself after millions of years.

It's not "mimics" (1)

HikingStick (878216) | more than 4 years ago | (#30457726)

A presently dying star cannot mimic the death of our own star, since it has not happened yet. How about using "foreshadows" instead?
