What would the sky or even a sunset on Gliese 581g look like, considering a Red dwarf star with a surface temperature of 3700 F?
Purple and the clouds would create a Purple Haze or mist, with rain falling in a purple darkened sky.
Seriously, no joke.
The sunset would be that region between the light side and the dark side of the tidally locked planet with the sun overhead, just if one was wondering or asking the question "Wait, how can there be a sunset or twilight region on a tidally locked planet?"

Is there a planet, is there not a planet, is there a planet, is there not a planet, pulling petals off the Daisy.

At this point in time, why not call it "Daisy World", pardon the pun.
"I stand by our data and analysis," Vogt, an astronomer at the University of California, Santa Cruz, said in an e-mail interview with SPACE.com."I feel confident that we have accurately and honestly reported our uncertainties and done a thorough and responsible job extracting what information this data set has tooffer. I feel confident that anyone independently analyzing this data set will come to the same conclusions."
Vogt added that he looks forward to reading the other team's results when they're published in a peer-reviewed journal. He's not necessarily expectingGliese581g to be yanked off the list of extrasolar planets, though.
"In 15 years of exoplanet hunting, with over hundreds of planets detected by our team, we have yet to publish a single false claim, retraction orer ratum," Vogt said. "We are doing our level best to keep it that way."
In the process of validation of the planet by various teams and making further observations, then the next phase would consist of the question to habitability; Vogt indicates it does exist in the "Goldilocks Zone". Yet, Venus or Mar's are in the fringes of the habitable zone in this solar system.
