Interesting news segment from Russia concerning two suns seen over Moscow Oblast November 25, 2012. (Unconfirmed Location) Could this be lense flare, a Sun dog or perhaps Nibiru, as always you decide.

Using the CFBDSIR wide field survey for brown dwarfs, we identified CFBDSIRJ214947.2-040308.9, a late T dwarf with atypically red J-Ks colour. We obtained an X-Shooter spectra, with signal detectable from 0.8 to 2.3 micron, which confirmed a T7 spectral type with an enhanced Ks-band flux indicative of a potentially low-gravity, young, object. The comparison of our near infrared spectrum with atmosphere models, for solar metallicity, shows that CFBDSIRJ214947.2-040308.9 is probably a 650-750 K, log g=3.75-4.0 substellar object. Using evolution models, this translates into a planetary mass object, with an age in the 20-200 Myr range. An independent Bayesian analysis from proper motion measurements results in a 87% probability that this free-floating planet is a member of the 50-120 Myr old AB Doradus moving group, which strengthens the spectroscopic youth diagnosis. By combining our atmospheric characterisation with the age and metallicity constraints arising from the probable membership to the AB Doradus moving group, we find that CFBDSIRJ214947.2-040308.9 is probably a 4-7 Jupiter masses free-floating planet with an effective temperature of ~700K and a log g of ~4.0, typical of the late T-type exoplanets that are targeted by direct imaging. We stress that this object could be used as a benchmark for understanding the physics of the similar T-type exoplanets that will be discovered by the upcoming high contrast imagers.

Astronomers have spotted a “rogue planet” – wandering the cosmos without a star to orbit – 100 light-years away.
Recent finds of such planets have suggested that they may be common, but candidates have eluded close study.
The proximity of the new rogue planet has allowed astronomers to guess its age: a comparatively young 50-120 million years old.
The planet, dubbed CFBDSIR2149-0403, is outlined in a paper posted online to appear in Astronomy and Astrophysics.
Rogue planets are believed to form in one of two ways: in much the same way as planets bound to stars, coalescing from a disk of dust and debris but then thrown out of a host star’s orbit, or in much the same way as stars but never reaching a full star’s mass.
One tricky part is determining if rogue planet candidates are as massive as the “failed stars” known as brown dwarfs, further along in stellar evolution but without enough mass to spark the nuclear fusion that causes starlight.
Either way, the objects end up free of a host star’s gravity. Given that most planets we know of are found through the effects they have on their host star’s light, pinning down rogue planets has proven difficult.
An international team went on a vast hunt for the planets using the Canada France Hawaii Telescope on Hawaii’s Mauna Kea and the Very Large Telescope (VLT) in Chile and came up with just one candidate.
VLT studies allowed first guesses as to the planet’s composition, as seen in this artist’s impression“This object was discovered during a scan that covered the equivalent of 1,000 times the [area] of the full moon,” said study co-author Etienne Artigau of the University of Montreal.
“We observed hundreds of millions of stars and planets, but we only found one homeless planet in our neighbourhood.”
But crucially, the new find appears to be moving along with a similarly itinerant group of celestial objects, called the “AB Doradus moving group” – a collection of about 30 stars which are of roughly the same composition and are believed to have formed at about the same time.
Because CFBDSIR2149-0403 appears to be moving with the group – to a certainty of 87% – astronomers believe it too formed with the stars, about 50 -120 million years ago.
It is this estimate of age that allows astronomers to use computer models of planet evolution to make further guesses as to the planet’s mass and temperature.
The team believe it has a temperature of about 400C and a mass between four and seven times that of Jupiter – well short of the mass limit that would make it a likely brown dwarf.
What remains unclear is just how the planet came to be – the tiny beginnings of a star, or planet launched from its home? Study co-author Philippe Delorme of the Institute of Planetology and Astrophysics of Grenoble, said that the latter implied a great many planets like it.
“If this little object is a planet that has been ejected from its native system, it conjures up the striking image of orphaned worlds, drifting in the emptiness of space,” he said.

While searching the Neumayer Live Camera in Antarctica, I noticed a secondary light source on the opposite side of the station. When the sun rises in Antarctica it is different then when we see it here in the states because Antarctica is on top of the world. The sun does not rise up and over, it rises and travels left if you can picture that in your head, so if you have (WWT) World Wide Telescope or Google Sky you can go to that view and rotate the eart around the sun and get a better picture of what I am saying. The South Pole is where we built a major Telescope to track Nibiru as it is on a Southern approach, no where else in the world will you see Nibiru any pictures or videos coming from anywhere else are photo shop that 100% fact. So here in Antarctica we have 2 light sources on opposite sides of the building . This can only be from a second sun Binary star in our system known as Nibiru or Planet X

This new Footage is captured on 1 September 2012 in the sky over Groningen, Holland at 09:20 AM. This amazing phenomenon last for almost 30 min.
