Over the past decade, researchers have been puzzling through Pluto’s mysteries. Meanwhile, the New Horizons probe heads for interstellar space.

Sedna, a distant dwarf planet three-quarters the size of Pluto, is inching toward the brightest star in our sky — and in 2076, it will reach its closest point in more than 11,000 years. Astronomers ...

Astronomers spotted an object speeding at 133,200 miles per hour (about 214,364 kilometres per hour), which is too fast to be from our solar system ...

In 1992, astronomers spotted the minor planet 15760 Albion, the first object ever spotted beyond Pluto and the first official member of the Kuiper Belt.

Sedna will reach its closest approach to the Sun in 2076, providing a remarkable space-faring opportunity that won’t come again for another 11,400 years.

Scientists have proposed two experimental spacecraft that could reach one of the farthest known objects in the solar system in as little as seven years. The team of researchers, from Italy, believes ...

For NASA's New Horizons spacecraft, though, the relative position of the stars is beginning to shift because it has now traveled way beyond our planetary neighborhood on its way to interstellar space.
