Asteroids floating through our solar system are debris left over from when our planetary neighborhood formed 4.6 billion ...

For astrobiologists, the search for life beyond our solar system could be likened to where one would look in a vast ...

A pair of planetary scientists simulated how our solar system might have evolved if it had a super-Earth orbiting where the asteroid belt is today. The results are enough to make you grateful that ...

“Lack of progress in solar and space physics over the next decade could have devastating consequences to society, in part because it would inhibit our ability to predict and mitigate against ...

The size of the solar system is defined by the volume of space over which the sun’s influence exceeds those of other nearby stars in the Milky Way galaxy.

None of this has improved my dimensia to the point that I can relate to the size of the solar system or the Milky Way, much less the universe.
