Voyager 1 and 2 traveled billions of miles to reach the heliopause, showing how the Sun's magnetic influence marks the boundary of our solar system.

It may not feel like it, but everything in the universe is in constant motion. Our Sun, with all its planets, orbits the center of the Milky Way, flying through the cosmos at around 450,000 miles per ...

We live in uninteresting times. Since the ructions that created the planets in the solar system’s first 100 million years (see “How was the solar system built?”) – and apart from an early migration of ...

As published in The Astrophysical Journal Letters, theoretical astrophysicists Konstantin Batygin and Jim Fuller of Caltech, ...

According to a new study, the Solar System may break apart within about 6 billion years as the dying Sun’s uneven mass loss destabilizes the outer planets.

For the first time, astronomers have detected radio signals from a planet beyond our solar system, according to a study available on the preprint server arXiv. The landmark observation offers a new ...

Imagine if the planet Jupiter orbited much closer to the Sun. What effect would a so-called hot Jupiter have on our Solar ...

The Solar System is made up of the Sun (our nearest star) and the objects that orbit around it, including planets, asteroids and comets. Planets orbit the Sun in roughly circular paths, and moons ...

The Voyager Interstellar Mission (VIM) is extending Voyager's exploration beyond our solar system's outer planets to interstellar space — the region outside the heliosphere, a protective bubble ...

Even at a glance, the planets in our solar system are wildly diverse. Huge and small, airless and densely packed with atmosphere, they have a wide range of characteristics distinguishing them. But if ...

It is not alien technology, but a colossal magnetic powerhouse.Harvard astronomers have pinpointed repeating radio bursts to ...
