Finding circumstellar disks in the Wide-Field Infrared Survey Explorer data is a tough job, but fortunately our brains are even better suited to the task than computers! You can help by lending your pattern-recognition skills to Disk Detective, the Zooniverse’s newest citizen science project.
Today’s paper is too awesome to be contained in merely one astrobite, so we’ve split it into two parts. In Part 1, find out how you can keep warm even if you’re far outside your star’s habitable zone (if “you” are a planet or moon, that is). Tune in tomorrow for Part 2: Superhabitability and You!
The Magellan telescope has directly imaged a planetary-mass companion at a projected distance of 650 AU from its star! Read on to find out how the authors detected and characterized this companion, and how they think it got there.
Can life spread from Earth to the moons of Jupiter and Saturn on rock ejected from meteoroid collisions? The authors of this paper start on answering this question by asking if ejected material from Earth can even reach the gas giants’ moons. The answer is yes, so it’s possible that microbial Earthlings have already traveled a lot farther than human ones.
