Planetary scientists recently simulated an alternate version of our solar system: one with a super-Earth causing climate chaos on Earth, Mars and Venus. If our solar system had a super-Earth, it's ...

Earth's climate has swung between ice ages and warmer periods for millions of years, driven by subtle changes in our planet's orbit and axial tilt. These variations, known as Milankovitch cycles, ...

Recent simulations and research have unveiled a fascinating new insight into the history of the solar system’s terrestrial planets. For years, scientists speculated about how the rocky planets—Earth, ...

Earth’s climate is not only shaped by smokestacks, forests, and oceans. It is also quietly tuned by the slow choreography of the planets, with Mars acting as a distant partner that nudges our world’s ...

A newly identified planet candidate, HD 137010 b, looks strikingly Earth-like in size and orbit — but it may be colder than Mars due to its dimmer star. If it has a thick enough atmosphere, though, ...
