Scientists have discovered an Earth-sized planet about 39 light-years away.
The planet’s average temperature, they estimate, is about 500 degrees Fahrenheit, meaning that it almost certainly cannot sustain water, which is necessary for the existence of life. The planet is being dubbed GJ1132b and most likely has another issue regarding its habitability: one half of the planet permanently faces its star, similar to the way the moon faces Earth.
It was discovered during routine telescope observation at MEarth-South Observatory. The Harvard University led array of telescopes is in Chile. The robotic telescopes have been regularly scanning the area of GJ1132b since [...]
