In the search to discover the origins of our solar system, an international team of researchers has compared the composition of the sun to the composition of the most ancient materials that formed in our solar system: refractory inclusions in unmetamorphosed meteorites.
The mysterious dark vacuum of interstellar space is finally being revealed by two intrepid spacecraft that have become the first human-made objects to leave our Solar System.
Scientists study the chemical composition of meteorites.
Most scientists thought it would be comet-shaped.
Scientists think a planet larger than Earth lurks in the far reaches of the solar system. Now a new telescope could confirm their belief and change solar system science
A new study explains how a stellar engine can be used to move the Solar System away from cosmic threats.

Here, off the northern coast of Greenland, the Arctic Ocean is masquerading as land, a snowy patchwork of smooth ice floes and abrupt, jagged piles of crystalline debris. Only
A grain of dust forged in the death throes of a long-gone star was discovered by a team of researchers led by the University of Arizona.
Just as dust gathers in corners and along bookshelves in our homes, dust piles up in space too. But when the dust settles in the solar system, it’s often in rings. Several dust rings circle the Sun. The rings trace the orbits of planets, whose gravity tugs dust into place around the Sun, as it drifts by on its way to the center of the solar system.
The strange orbits of some objects in the farthest reaches of our solar system, hypothesized by some astronomers to be shaped by an unknown ninth planet, can instead be explained by the combined gravitational force of small objects orbiting the sun beyond Neptune, say researchers.
