Scientists say that there is a wall separating the solar system from the rest of the galaxy. The famous New Horizons spacecraft finally gets a glimpse of this boundary, according to a new study.
The planet Uranus is another interesting object in the Solar System because of its strange rings. But a recent study suggests that it's not the only surprising thing about the planet as there were signs of two hidden moons uncovered.
Astronomers reexamining data from Voyager 2 has observed evidence indicating the existence of two tiny, never-before-seen moons lurking within the dark rings of Uranus.

NASA's Voyager 2 spacecraft has taken unprecedented views of Neptune's moon Triton, describes a new study.
