Exoplanets Spotted Orbiting Dead Star
astroengine writes "Scientists have found a system of planets that appears to have survived being engulfed by their dying parent star. The discovery raises questions about the ultimate fate of our solar system when the sun runs out of hydrogen gas in about 5 billion years and violently transform into an expanding red giant star. Scientists believe all the planets from Earth inward will be destroyed when the sun expands, but new research suggests that if planets are large enough, they may outlast their parent star's death, even if they are engulfed."
5 billion years from now that could be us!
Don't you want to know how it will end?
No brain, no pain.
So...your grave still exists on whats left of a scorched rock vs being completely destroyed leaving nothing but particles in space? Sounds WAY better!
If reincarnation turns out to be real, you will...
Did they find planets orbiting a white dwarf at orbits that would have been inside the red giant, did they find planets orbiting a red giant or did they find planets orbiting inside the red giant? Is the star dead or dying? TFA doesn't seem to say anything about the former, and conflicts with TFS about the latter.
You're on the wrong site.
... for what's going to happen to us.
We're going to die off and be forgotten because humankind has turned away from space exploration and instead has focused on socialism. Stealing from the productive to give to the lazy is now our final fate.
But... I was hoping humanity would still be around to see the copyrights to "Steamboat Willy" expire!
It's sure been a long time since I've used/seen $TITLE in online conversation.
I'd love to Sun expand again, and devour Oracle.
First a story about a comet flying through the sun unharmed. Now a story about planets surviving an expanding sun. Clearly a new PR strategy of the Climate Change Deniers (tm) !
Who the *beep* cares? Seriously....
Because probability dictates a good chance of a Futurama-like world will exist sometime during that span. If you want to be a part get started on your own stasis chamber, now. Don't forget to take a pizza with you, so you'll have something to eat when you emerge.
In the meanwhile, I'm more worried about the survivors of those dead worlds, who are on their way here.

I do.

That is perfectly okay. They will land a job in a newspaper somewhere...and wear their underwear outside their pants!
...that we're doomed when the Sun starts burning out. There's a certain group of astronomers over in England who've been studying the Sun for the better part of a quarter of a century who've come to the conclusion that even though they know the Sun will not be going red giant and swallowing up the Earth for a very long time (some models are as short as 600,000 years, others up to 4 billion years), one mathematical model of theirs shows that just the simple increased solar output will cause a planet-wide drought that will render the Earth practically uninhabitable by life as we know it in as little as 1800-2200 more years from today. And that model has shown to be dead nuts accurate with the solar output increases recorded on Mars for as long as we've been able to measure the temperatures on Mars. Pretty scary stuff. If we've really only got in the neighborhood of two millenia to get our act together and build some deep-space-faring city-ships, then that ist really very little time left to accomplish that.

Ummmm.... Well done. Just like I do my stake.
Can we please call it the Cajun system?
In my case, I was wondering if somebody would mention if the lack of a "permanent" energy source like the Sun would spell the death of our planet anyway, if the dying, expanding Sun didn't get rid of it first after all.

Then, in many trillion years an intelligence might stumble across that message embedded in the rock that was the Earth. Then they, using some multiverse extra-physics principles of which we're unaware of, they can travel back in time to now. Once here they can establish a connection to our Internet at a local Starbucks, peruse this thread and forever know that the bird is the word.
That is perfectly okay. They will land a job in a newspaper somewhere...and wear their underwear outside their pants!
As a former resident of an exoplanet I must protest. This is an stereotype created by pop culture, not all aliens wear their underwear outside their pants, you insensitive clod!
Climate change is b**ch!
It's also possible that between the expanding star and loss of inner planets, the other planetary orbits were disrupted, one or more planets were ejected from the system and formerly outer planets migrated inward.

That's no moon!
Awww, jeez. The Cubs will never win the series now.
Exoplanets with stripes???
In 800 million year to 1 billion year the sun luminosity will have increased so much as to make existence of life and even water in liquid form a rarity on earth, baring complete extinction.
As for those purporting we should think about earth extinguishing and prepare the way for a futurama like civilisation :
1) we aren't able to even get agreement on something as simple as CO2 and GCC which is a threat *now*
2) we are still eating oil like tehre is no tomorow. And the way I see it : there won't be, because if we don't find an alternative source like fusion, our age of tech will *end* and there won't be another one *ever* (too much research depend on plentyful energy , so to regain back what we had, would be next to impossible)

You did notice that McDonalds latest item is McPopplers, right?
You are much too funny...................I betcha when searching for exo's, popping into veiw will be an un-organic vehical with a smiley face flag and the "Flintstones" theme song being broadcast.

Exoplanets Spotted Orbiting Dead Star
Wait till Emperor Palpatine finds out. Grand Moff Tarkin is gonna blow them the fuck off the spatial plane for orbiting too close to their security perimeter.
Will the surface of the Earth be completely replaced, and if so how many times, before the Sun explodes?
Estimates for the Sun's lifetime are very common, but I've never seen lifetime numbers for the Earth's surface based on plate tectonics, mid-ocean rift spreading, and other crust replacement factors.
