Voyager 1 has officially crossed the heliosphere, left our solar system and entered interstellar space. 35 years in the making!!!

Congratulations mankind and NASA!!!
Support NASA.
Update: Top of the Rec List? LOL! Thank you!! My wife, Shaking The Tree is jealous. On another note, the consensus of the team is that it probably hasn't left. However, I have first hand info from a buddy at JPL that this wasn't unanimous. There were some great pics of the components of the heliosphere and both voyager locations but I couldn't post them due to them being on the NASA site.
Here is a good one, though a tad old. Here's another. I can't get enough of them tbh. I'd post more but I just got home from the datacenter and I have to do some remote work for a couple hours.
Update2: Cool pics linked to above. Joan McCarter is persistent and doesn't appreciate my laziness.
If the bright blue area were a basketball, the sun would be the size of a mustard seed. Space is big.
