Animations show the evolution of density and flow in simulations of a planet embedded in the envelope of a giant star, showing the interactions of the inspiralling planet with the gas in its vicinity.

Astronomers have confirmed the existence of a massive planet in the Nu Octantis binary star system, first suspected in 2004. Using advanced tools like the HARPS spectrograph, researchers found that ...

Retrograde mean motion resonances occur when orbiting bodies, moving in directions opposite to the dominant sense of motion, experience periodic gravitational interactions that can stabilise their ...

The planets of our solar system move in ellipses. We've known this, so we are told, ever since Johannes Kepler devised his laws of planetary motion in the early 1600s. While it's true that orbits are ...

A computer simulation that traces the moon’s formation in high resolution may explain the mystery of why it is so chemically similar to Earth. The conventional story for the moon’s origin is that a ...

What would we do if we knew an asteroid would hit Earth in 2027? That's what NASA personnel will explore during a simulation taking place next week. The project will play out as a tabletop exercise ...

Asteroid experts have been simulating a large asteroid heading towards Earth. Friday is the conclusion to the realistic simulation and will reveal how well planetary defense efforts work in this ...
