Colonization of the outer Solar System the Solar System's gas giant planets for exploration and possibly mining of helium-3, which could have a very high value per unit mass as a thermonuclear fuel. The Jovian system in general has particular disadvantages for colonization, including its severe radiation environment and its particularly deep gravity well. Its radiation would deliver about 3,600 rems per day to unshielded colonists on Io and about 540 rems per day to unshielded colonists on Europa. Exposure to about 75 rems over a few days is enough to cause radiation poisoning, and about 500 rems over a few days is fatal. Jupiter itself,
OGLE-2014-BLG-0124Lb AUs from it. The two telescopes, OGLE and Spitzer, discovered the planet through gravitational microlensing. This is done by observing when the star passes between Earth and another star. The distance at which the star is seen allows us to observe gravity bending the light and the change of brightness shows the existence of the star. If there is a planet orbiting the star, then the astronomer will also see the same thing twice, which helped astronomers discover OGLE-2014-BLG-0124Lb. OGLE-2014-BLG-0124Lb is known as an exoplanet. These planets are located outside of our solar system. The Kepler telescope has allowed astronomers
