Image: When a large nearby object, such as a galaxy, blocks a distant object, such as another galaxy, the light can detour around the blockage. But instead of taking a single path, light can bend ...

A group of researchers has released a new map that brings science closer to an accurate estimation of the true size and age of the universe. The new research was published in The Astrophysical Journal ...

Astronomers have recently discovered that the Hercules–Corona Borealis Great Wall, a massive cosmic superstructure, might be much larger and closer to Earth than previously estimated. This remarkable ...

Space. It's really, really big. How big is it? Well, according to astronomers, the observable universe is around 92 billion light-years in diameter, but that's all we can see (hence the word ...
