We will survive?
I am pleased that you think the earth may survive. I plan to live forever, and so far so good.
Earth may survive longer than we expect - scientists have stumbled across two deep-fried planets orbiting the glowing embers of a dying star. The two flame-grilled planets, dubbed KOI 55.01 and KOI 55.02, are slightly smaller than the Earth and have been spotted in a very tight orbit around a subdwarf B star - one that has …
I'm not sure this finding gives much hope for Earth. From what I've heard these planets were once gas giants, with only their charred iron cores surviving the cremation. Any process that can strip a Jupiter down to a sub-terrestrial sized husk is not going to do wonders for the Earth's habitability!
Oh, no not again!
This is observational confirmation of an alternative model of the solar system that represents a paradigm shift second only to the Copernican Revolution of 1543. Snowball Solar System suggests that our solar system formed with a binary star whose components merged in a luminous red nova (LRN) at 4.567 Ga to form our solitary sun. And the red giant phase of the LRN engulfed the inner planets out to Jupiter, resulting in their present volatile depletion (planetary volatility trend) and their metallic-iron cores.
If so, Earth and Venus may have originally formed as ice giants like Uranus and Neptune before their direct exposure to solar plasma.
"Earth's fate is precarious. As a red giant, the Sun will have a maximum radius beyond the Earth's current orbit, 1 AU (1.5×1011 m), 250 times the present radius of the Sun. However, by the time it is an asymptotic giant branch star, the Sun will have lost roughly 30% of its present mass due to a stellar wind, so the orbits of the planets will move outward. If it were only for this, Earth would probably be spared, but new research suggests that Earth will be swallowed by the Sun owing to tidal interactions. Even if Earth should escape incineration in the Sun, still all its water will be boiled away and most of its atmosphere will escape into space." (Wikipedia)
But no more large heating bills in the winter.
