For decades, science fiction writers have tried their best to prepare us for eventual contact with aliens. Their efforts are dominated by several recurrent tropes. There's the invasion by a warlike species, there's the highly-evolved species trying to communicate with our primitive species, there's the benevolent aliens come to save us from ourselves, and there's the mischievous anal-probers and medical experimenters.

The cosmos is populated with many puzzling, gigantic, and awe-inspiring objects. Supermassive black holes billions of times more massive than the Sun reside in the center of massive galaxies. Huge stars explode in cataclysmic collisions whose light reaches us from more than 10 billion light-years away. Enormous galaxies collide and merge, leading to tremendous bursts of star formation.

If you read enough articles about planets in binary star systems, you’ll realize almost all of them make some sort of reference to Tatooine, the fictional home of Luke Skywalker (and Darth Vader) in the Star War saga. Since that obligatory reference is now out of the way, we can talk about the new “super-Jupiter” that researchers from two separate research teams, including one at Northwestern University and one at the University of Exeter, simultaneously found in old data from the Gemini Planet Imager (GPI).
Smooth filaments stretching for many light-years, seen by the powerful space telescope, could indicate what the right "recipe" is for dark matter.
