They have found an ultraviolet glow at the edge of the solar system. It is further out than they expected.
....glow at the solar system’s edge
"New Horizons is the first spacecraft in a position to double-check the Voyagers’ observations. It scanned the ultraviolet sky seven times from 2007 to 2017, space scientist Randy Gladstone of the Southwest Research Institute in San Antonio and colleagues report. As the spacecraft travelled, it saw the ultraviolet light change in a way that supports the decades-old observations. All three spacecraft saw more ultraviolet light farther from the sun than expected if there is no wall. But the team cautions that the light could also be from an unknown source farther away in the galaxy."

The Voyager space craft is considered by some to have left the solar system. There seems to be some doubt though..
"The sun, planets and Voyager probes sit inside the tiny yellow dot at right, within a giant sphere called the Oort cloud. This reservoir of trillions of ice chunks extends 100,000 astronomical units out, tethered to the sun by gravity. Astronomers believe these objects got thrown out of the inner solar system as the planets took shape 4.5 billion years ago. Occasionally these castaways pass near Earth: The comet ISON, which may light up the night sky this November, started out in the Oort cloud. The Voyagers would have to travel another 30,000 years before clearing this broadest definition of the solar system."

I have called the solar system and area the fishbowl, to try and get some perspective on the size in this universe.
The pic linked to above shows a little yellow dot representing the solar system and area. Ha.
