SpacePorn is a subreddit devoted to high-quality images of space. As long as the focus of the image is of the stars or related to space in some way then it is allowed. This includes artwork as well as photography.
/r/EverythingScience is the sister subreddit to /r/science. With a broader rule set that /r/science, it is the place for high quality scientific content that doesn't necessarily reference a peer-reviewed paper from the last 6 months.
The aim of /r/Physics is to build a subreddit frequented by physicists, scientists, and those with a passion for physics. Papers from physics journals (free or otherwise) are encouraged. Posts should be pertinent, meme-free, and generate a discussion about physics. Please report trolls and intentionally misleading comments.
