A planet circling at a sharp 90-degree angle to the orbits of its two host stars has now been confirmed. This discovery challenges long-standing ideas about how planets form and orbit in the cosmos.

Studying the orbits of thousands of exoplanets shows that large planets tend to have elliptical orbits, while smaller planets tend to have more circular orbits. This split coincides with several other ...

Most astronomers would love to find a planet, but Mike Brown may be the only one proud of having killed one. Thanks to his research, Pluto, the solar system’s ninth planet, was removed from the ...

Everything that has a beginning will have an end. From organisms to planets, the arc remains the same for all parts of the universe, even for one of t.
