With a diameter of 88,846 miles at its equator, Jupiter is the biggest planet in our solar system. It’s eleven times larger than Earth, so big in fact that its gravitational forces are thought to be ...

Jupiter is already the biggest planet by far in our solar system, but new research suggests it was somehow once even larger than it is now. Twice as large, in fact. To put that into context, those ...

We live on a planet that seems motionless, yet Earth orbits the Sun at a dizzying speed, and our entire Solar System moves through the galaxy. But how fast exactly are we traveling through the cosmos?

The sun rises and sets every day. We plan our lives around it. It's ironic, then, that "we know so little about the star at the center of our solar system," says Matina Gkioulidou, a space physicist ...

The workings of our solar system are roughly the same now as they have been for millions of years. Moons circle their planets, the planets circle the sun, the sun’s magnetic fields and sunspots wax ...

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 ...

As detailed in a paper to be published in the journal Nature Astronomy, the international team of researchers spotted the crescent-shaped gas cloud, dubbed Eos, on the edge of the Local Bubble, an ...

The Interstellar Mapping and Acceleration Probe (IMAP) is being launched later this month to study the outer reaches of the heliosphere which defines where our solar system ends and interstellar space ...

The shocking findings were part of a recent study in which astronomers effectively peered back in time to discover what Jupiter was like in its early years. Jupiter is not only the largest in the ...
