"We are a way for the cosmos to know itself."

Rage/Meme Comics, Spam links and disrespectful comments will be removed.

Repeat and/or serious offenses will earn you a ban.

Please avoid multiple exclamation marks, excessive CAPS, or editorialize in your submission titles. Nine times out ot ten, the actual article title is perfectly usable.

While we welcome pics to this community, the focus of the sub is tilted towards astronomy as a discipline. As such, we typically remove pictures that are not of an exceptional quality (i.e., no cell phone).

Photos should be original content and include acquisition information or link to the original source (ie, Hubble, NASA, etc...).

If your photos do not meet these guidelines, consider posting in /r/photos or /r/astrophotography.

Remember, keep looking up!
