An accidental discovery in an astronomy show offers researchers a new clue about the mysterious Oort Cloud, a large expanse of icy bodies revolving around the sun.

Astronomers have discovered a massive gas giant, TOI-6894b, orbiting the red dwarf star TOI-6894, a pairing that defies current planetary formation th ...

In particular, there is the long-standing question of whether or not the planets' orbits will remain stable over time. However, these studies have generally treated the solar system as an isolated ...

Over millions of years, these objects grew larger, sweeping up material in their orbits and becoming the planets we know today. This model of solar system formation is known as the nebular hypothesis.

This may explain the strange properties of the orbits of our solar system's planets, which are not quite perfectly circular, and all lie on slightly different planes. NASA artist’s conception of ...
