A convenient solar flare helped stir up the plasma and allow surrogate instruments to determine the spacecraft was in fact in interstellar space.

This is obviously terrific news! We're halfway there (just kidding...more like a thousandth of a way there) to making Star Trek and/or Star Wars a reality. Congrats to NASA JPL and the Voyager team!

Good to see this currently the most read story on the BBC news website.

RELEASE 13-280
NASA Spacecraft Embarks on Historic Journey into Interstellar Space
Quote
NASA's Voyager 1 spacecraft officially is the first human-made object to venture into interstellar space. The 36-year-old probe is about 12 billion miles (19 billion kilometers) from our sun.

So, at long last it has been confirmed and Voyager 1 truly enters something that has been theoretically postulated but never actually sampled by any human-made tool - the interstellar medium.  From this moment forward, the team at JPL are literally in the unknown.  Every bit of data will be unprecedented.

It said that for a long time already.

Haven't looked for a little while.

I wonder when it is calculated to encounter the Oort Cloud.

The Oort Cloud is a highly speculative region of space. A region of shared material between neighboring stars. It has not even been shown to exist. So until there is positive verification, I wouln't put much into it.

It's official.  Voyager 1 is humanity's first starship.  Congratulations!

It's on a trajectory to reach within 1.7 light years of star - AC+79 3888 40,000 years from now. 

And here's an image of Voyager 1 "out there" from the NRAO:

Today is a historic day.  Our first reach into interstellar space.
I'll even excitedly look forward to "flags and footprints" and suborbital missions. Just fly...somewhere.

Oort Cloud question. If the Oort cloud is actually there, why hasn't any of it's material eclipsed any visual observations of stars? If all this material is there it should have shown up in observations by now.

It's incredibly diffuse and far away, up to a light year.

That's if it exists at all. I'm not so sure.

It's based on studying the orbits of long-period comets.

I found my answer on this & it appears to be 300 years. Interestingly I noticed a number of the articles about this news were updated to include a mention of the Oort Cloud as the actual boundary point of the Solar System & also where the influence of gravity from other stars overtakes that of the Sun.

Voyager 1 should arrive at the Oort Cloud in 300 years, and exit it in 30,000 years. Obvious comment of the day: Space is huge.

What the theory also states is the that the Oort cloud is made up of shared material with other neighboring stars so if you were traveling to the nearest star system you would not pass through a boundary instead it would be shared between star systems. I have a feeling that long period comets do not make up enough material to make up a "cloud" of material. How do we know that there is a cloud at all. It could be that interstellar space is littered with space junk from the formation of stars and our galaxy and once our sun's gravitational pull intersects with those objects they are captured.

The comets would be going FAR faster if you were right. So far, pretty much everything seems to be coming in at about solar escape velocity, not with extra velocity due to the Sun's motion with respect to nearby stars (which is about 20km/s).
