Voyager 1 has reached the heliosheath as evidenced in the linked article. “Who cares?” you ask, whilst munching popcorn, watching clonetroopers duke it out with Jedi? I do! And you should too, as this is a phen0menal display of engineering acuity.
Voyager 1 was launched 35 miles from my house, in 1977. At least, the house I lived in then. Since that fiery debut, it has passed the gas giants and coasted all the way to the edge of interstellar space. Rumor has it that Nasa wants to cut funding for the Voyager program and turn off the probes. It think that would be a shame at this stage, with no other programs in the works to explore the same regions.
