An accidental discovery in an astronomy show offers researchers a new clue about the mysterious Oort Cloud, a large expanse of icy bodies revolving around the sun.

If our solar system seems stable, it's because our short lifespans make it seem that way. Earth revolves, night follows day, the moon moves through light and shadow, and the sun hangs in the sky. But ...

Now, in three papers that together exceed 150 pages, Guàrdia and two collaborators have proved for the first time that instability inevitably arises in a model of planets orbiting a sun. “The result ...

With 3.2 billion pixels and a decade-long search, the Rubin Observatory will reveal what’s been hiding in plain sight.

Activity 1: Solar System Model (30 minutes) Hands-on Activity : Students will create a model of the solar system using Styrofoam balls, paint, and string. Assign each student or group a planet to ...

Wanderers CU is a responsive sound experience delivered via a mobile app that responds to the visitor’s movement as sensed by GPS. A complement to the Colorado Scale Model Solar System represented by ...

If this is the case, Beer and his colleagues argue in their research paper, it is unreasonable to base our understanding of all planetary systems on the one around the Sun. They go on to speculate ...

The Arizona Scale Model Solar System is a collection of 10 informational signs stretching from the Kuiper Space Sciences Building on the UA Mall to Main Gate at the west edge of campus.

In that paper, they predict a 50 percent chance that our solar system will be pushed away from the galactic core by three times its current distance of 26,660 light-years.
