Interstellar Updates

These are items of interest to the interstellar exploration community that we’ve found in our quest for information that will help us advance toward our goals.  If you know of anything we’ve overlooked, or any sources of such information we should monitor, or if you would like to be added to our IRG-updates mailing list and receive these updates in you email every weekday, please send that information to

You can now search our database of interstellar updates and find items of interest to you.
