Instead, astronomers rely on a star'sphotosphereto determine its size. The photosphere is where the star becomes transparent to light and the particles of light, or photons, can escape the star. "As far as an astrophysicist is concerned, this is the surface of the star, as this is the...
The biggest single entity that scientists have identified in the universe is a supercluster of galaxies called the Hercules-Corona Borealis Great Wall. It's so wide that light takes about 10 billion years to move across the entire structure. For perspective, the universe is only 13.8 billion yea...
It all depends on what you mean by a "thing". The biggest physical object is probably a star. The largest possible red giant star could be as big as 2,100 times the size our Sun. Placed inside our own Solar System, a monster star like this would extend out past the orbit of Saturn...

Star jelly sounds like it could be some sort of cosmic spread for toast -- complete with a flashy label boasting, "Now with 50 percent more universe!" Unfortunately, the real story of star jelly is far less tasty -- and far more terrestrial.
We should not think of the universe in the same way. The universe doesn't have an outer perimeter, and nothing exists outside it, because there isn't an outside. As an analogy, consider the shape of our galaxy, the Milky Way. We can infer that it is a spiral based on maps of th...
