This Map Shows Just How Little We Know About Our Own Galaxy


So, you think you know the Milky Way? Well you don't. This latest Milky Way map from NASA displays the exo-planets we've discovered so far, including the newly established exoplanet 13,000 light years gone from Earth, catchily-named OGLE-2014-BLG-0124L. It's about half as far away as the farthest exoplanet still found, one of only a few handfuls to be discovered beyond Kepler's range.

The popular of exoplanets that have been discovered were the work of the Kepler,
but the very furthest ones that have been found — like this recent one — owe their discovery to microlensing methods. Like gravitational lensing, where gravity bends space and light to generate a natural "zoom lens" that lets us see further afield, microlensing also make use of certainly happening bends in space. In microlensing, however, that enlargement procedure is triggered by a fainter star transitory in front of an additional distant star, creation the space around the distant star new easily observable.
