The Eridanus Void. This area shows almost no signs of cosmic matter, meaning no stars, planets, solar systems or clouds of cosmic dust. Researchers couldn't even find dark matter, which is invisible but measurable by its gravitational pull. There were also no signs of black holes that might have gobbled up the matter once present in the region.

Who’s visiting who? This chart of solar system exploration shows every robotic space probe currently exploring (or about to explore) a major solar system object… except for the Earth and Sun of course, because there are way to many of those to show on one chart.
