Watch out - the planet rises from the dead! Sort of. Well, they like to say it has risen from the dead (maybe) but in reality, the scientists just don't know and can't agree.
Fomalhaut b (okay, okay, so I already wrote about this planet) was thought to be just a cloud of dust. Then someone said, "No! I think there's a planet in there!" So they started looking, searching, gazing into the vast expanse of night - until a third party replied, "Well, there's no heat signature. It's just a dust cloud."
Op. Now it's dead. A dead planet.
Well... then they changed their minds. At least, somebody did. They decided that they were seeing a planetary object embedded in a cloud of dust, instead of just, well, a cloud of dust.
So this planet has come back to life via the aid of red tape and limited scientific equipment.
Humans are great. So are Zombie Planets.
In conclusion, Happy Halloween, Fomalhaut b!
