Parker Solar Probe by the Helios 2 spacecraft. The "Parker Solar Probe" concept originates from a predecessor "Solar Orbiter" project conceived in the 1990s. Similar in design and objectives, the "Solar Probe" mission served as one of the centerpieces of the eponymous Outer Planet/Solar Probe (OPSP) program formulated by NASA. The first three missions of the program were planned to be: the "Solar Orbiter", the Pluto and Kuiper belt reconnaissance mission "Pluto Kuiper Express", and the "Europa Orbiter" astrobiology mission focused on Europa. The original "Solar Probe" design used a gravity assist from Jupiter to enter a polar orbit which dropped almost directly
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
