Doomed Planet Foreshadows Earth's Fate

% of readers think this story is Fact. Add your two cents.


A group of astronomers that includes Amelia Bayo and Luigi Mancini of the Max Planck Institute for Astronomy has found a doomed planet that within 55 million years – a mere blink of the eye on astronomical scales – will be swallowed whole by its host star.

The evolution of planetary systems is intimately linked to the evolution of their host star. Our understanding of the whole planetary evolution process is based on the large planet diversity observed so far. To date, only few tens of planets have been discovered orbiting stars ascending the Red Giant Branch. Although several theories have been proposed, the question of how planets die remains open due to the small number statistics, making clear the need of enlarging the sample of planets around post-main sequence stars.

This is a fate similar to that facing the earth in roughly 5 billion years. The planet, known as Kepler 91b, is currently orbiting its host star a mere 3 times the radius of the sun. The star, a red giant with a radius currently 6 times that of our sun, will swell to engulf the unhappy satellite.

The team leader is Jorge Lillo of the Center of Astrobiology (CAB) in Madrid. The initial discovery was made with NASA’s Kepler Space Telescope based on observations taken in 2009–2012, but the object was only unambiguously identified as a planet when Lillo and his colleagues followed up on the initial observations, using the 2.2m telescope at Calar Alto Observatory in Andalusia. precarious.

      if th esun is so big how come it takes keplar only 220 days to go around it.?

        hahahahahahahaha…. it is called velocity and distance… good grief, do some research!

      Unfortunately, the entirety of “main sequence” astrophysics is in error.
      Sir Arthur Eddington originated the idea that stars are thermonuclear processes; but he had the sense to point out that many of the corollaries of this wonderful theory were simply not being observed as might have been expected. However, as people tend to be very slavish and parrot-like in how they approach all the great and little questions of life; his caveats were soon forgotten.
      Big mistake.
      Here is a small but perfectly-formed objection to the Standard Model. Our sun is a star. At its surface, its temperature is about 5K degrees. Quite cool, really. But 200 km above its surface, the temperature is tens of millions of degrees K. No normal fiery mass displays this sort of entirely unexpected temperature inversion. It is completely illogical. Therefore, a better hypothesis would be that the sun’s energy arrives at its surface not from within, but from without. The universe is criss-crossed with visible and often glowing streams of high-energy plasma; these are called Birkeland Currents, and they provide the sun with the energy it then focuses upon its dark core. You will be aware that sunspots are darker than the surrounding surface; this indicates that the interior of the sun is a cold object.
      Thus stars do not have a sequential and predictable lifespan. Several have been observed going through evolutionary changes entirely out of keeping with expectations; but this is just ignored by the mainstream, including these wonderful people at the Max Planck Institute.
      Stars are really more like lightbulbs; they can be switched on and off, and they sit in electromagnetic orbitals whose radii can be changed in a moment by varying the charge distribution in their local areas.
      The Bible tells us the truth. Amos 8 verse 9, “And it shall come to pass in that day, saith the Lord God, that I will cause the sun to go down at noon, and I will darken the earth in the clear day”. This is a clear reference to switching the sun off; we find a further reference at Joel ch 2 v 10, “The sun and the moon shall be dark, and the stars shall withdraw their shining, for the Day of the Lord is great and very terrible, and who can abide it?”
      This absolute control over such vast forces is to be expected of the Lord God who made these objects.
      “For thus saith the Lord who created the heavens, God Himself who formed the earth and made it…”
      “Mine hand also hath laid the foundation of the earth, and My right hand hath spanned the heavens, when I call unto them, they stand up together”.
      The crucifixion of the Lord Jesus Christ was accompanied by a darkness over the whole earth. Now you know, I hope, that this darkness was not as the result of a purely local eclipse phenomenon.
      The One who was being judged by His Father was the very One who had created the once-fiery orb gazing down upon Him, but which was now cloaked in darkness.
      “The fear of the Lord is the beginnin g of wisdom, and to depart from iniquity is understanding”.
      The Electric Universe w/s has all the data you could wish for in support of these ideas.
