If the "brown dwarf" planet X is the same planet X that was allegedly messing with orbits, that was disproved IIRC.
The colour thing isn't too uncommon, I've seen it happen a few times when looking through telescopes and generally put it down to heatwaves (doesn't have to be hot, any difference in temperature can produce them, particularly relevent when looking at distant objects and/or through a scope) and/or other problems with having an atmosphere.
I haven't the foggiest idea how something could rist in the southwest and set in the west. That can't be natural. Note: not alien, just not natural

I think that's a load of utter nonsense personally - either that or an airplane. Or possibly a seagull carrying an LED keychain.
