Presolar Dust Stardust

There are many who believe that Earth came into existence at (or very near) the same time the known universe was born.  However, recent research suggests that this may actually not be the case.  Scientists have gathered evidence that indicates solids existed before planet Earth was an actual object.  One such piece of evidence is stardust.

Large Celestial Bodies: What is the Largest Object in Space?

Celestial Bodies

Space is vast – our own planet, which basically consists of everything most of us know, understand, and are familiar with, makes up a very tiny part of the entire universe.  In fact, the entire galaxy (the Milky Way Galaxy) makes up far less than 1% of the universe.  The sun, the biggest celestial body in our own solar system, is nothing compared to some of the largest celestial objects that exist.  That begs the question – what is the largest celestial object in outer space?

Our Universe: Expanding, Evolving, and Massive in Scale

It encompasses dimensions like height, width and length. It is everything!
