Our sun is about five times less magnetically active than other sunlike stars—effectively a special case. The reason for this could reside in the planets in our solar system, say researchers at the ...

Astronomers are closing in on one of the most tantalizing possibilities in planetary science, evidence that a previously unknown world may be lurking in the outer reaches of the solar system. The ...

The Sun is an incandescent but benevolent dictator. For billions of years, it’s kept our star system well organized through the influence of its powerful gravity. All the planets revolve around it on ...

Our solar system is a smashing success. A new study suggests that from its earliest period — even before the last of its nebular gas had been consumed — Earth’s solar system and its planets looked ...

Our solar system passed through a vast wave of gas and dust around 14 million years ago, dimming Earth’s view of the night sky. The wave may even have left traces in our planet’s geological record.

Dark matter refers to material that does not absorb, reflect, or emit any electromagnetic radiation. Astronomers have ascertained the existence of dark matter through the gravitational influence it ...
