Astronomers Locate Geidi Prime, House Atredies Put on Alert

The Jupiter-sized gas giant named TrES-2b was found using NASA’s Kepler spacecraft, which has the capacity to measure light, even in extremely distant objects. However, TrES-2b reflects less than one percent of light shined upon it, making it the darkest planet or moon ever discovered thus far.
“TrES-2b is considerably less reflective than black acrylic paint, so it’s truly an alien world,” said lead author and astronomer David Kipping of the Harvard-Smithsonian Center for Astrophysics (CfA).
TrES-2b is heated up to temperatures greater than 1,800 degrees Fahrenheit by its star, which it orbits from a mere distance of 3 million miles. This planet is unique as it does not have any clouds similar to planets like Jupiter, cloaked by clouds of ammonia. Rather, high temperatures prohibit any clouds from forming, causing a mystery as to why the planet is so dark and unreflective.
What said astronomers forgot to mention, it’s Giedi Prime. All of you who haven’t read or watched DUNE(David Lynch or SyFy miniseries style) need to get caught up on this.
In the meantime, science has found House Harkonnen lurking in The Black. This means, we’ve got to get on that traveling without moving business and bring the rain to Arrakis.*

FOUND: Super Earth, ‘Goldilocks,’ is Better than Porridge

She has a possiblity of holding Earth-like atmosphere. Which means water and all those good things. And she has a red dwarf star to boot.
For the first time, astronomers have spotted a cosy alien planet that might be hospitable to life. The planet is not much bigger than the Earth, and it enjoys balmy temperatures of about 20° C (68° F) as well as spectacular scarlet sunsets.
“It’s the smallest, lightest planet known at this time,” says Stéphane Udry from the Geneva Observatory in Switzerland. “And it’s just at the right distance from its star for liquid water to possibly exist on its surface.”

“If you take an average value for the amount of starlight heating the planet, you get something like 20° C,” Udry told New Scientist. That’s similar to the average temperature in New York City, US, in June.
Astronomers have discovered “super-Earths” slightly larger than this one before. However, they are either too hot or too cold for liquid water to exist. The smallest world circling Gliese 581 is a “Goldilocks” planet with the conditions just right for potential life.
Whether DEADLY SPACE BEARS are present is not yet known.
