Star and planet formation has largely been considered separate, sequential processes. But in a new study, scientists at Southwest Research Institute (SwRI) have modeled a different scenario where ...

As planetary systems evolve, gravitational interactions between planets can fling some of them into eccentric elliptical orbits around the host star, or even out of the system altogether. Smaller ...

A recent massive stellar explosion has fundamentally reshaped our understanding of how such cosmic events impact planetary ...

If you were to perfectly follow the steps in An Idiot's Guide to Making a Solar System, you should eventually find yourself with a star surrounded by a flat disc of planetary material orbiting in ...

For the first time ever, the James Webb Space Telescope has discovered an exoplanet by directly imaging it. The newfound world has a mass roughly similar to Saturn and orbits inside the debris disk ...

One hundred light years away, a handful of planets are circling a star in the same configuration as when they formed. By Katrina Miller Astronomers have discovered six planets orbiting a bright star ...

Astronomers gazing upon a star system not too far from Earth were recently treated to a marvelous discovery: a group of six planets moving around a sun-like star in a seemingly perfect cosmic dance ...

Theorbits of Jupiter, Saturn, Uranus and Neptune may have been altered by the fly-by of an enormous object from deep space, billions of years ago. According to a pre-print research paper, which is yet ...

Because their orbits are unstable, a possibility exists that the asteroids could break off from their current trajectory and one day head on a collision course for Earth. The Venusian space rocks are ...
