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 new JCAP study tests an “emulator” to reconstruct the large-scale structure of the cosmos If you think a galaxy is big, compare it to the size of the Universe: it’s just a tiny dot which, together ...

From subatomic particles to galaxies billions of light-years away, the scale of the universe is beyond mind-blowing—yet most of us can barely grasp it. This video breaks down the cosmic vastness step ...

As evidenced by the diagrams that make up the Tree of Knowledge System, I think it is valuable that we teach individuals broad frames to think about the Universe and our place in it. That was why I ...

It’s hard to fathom the size of the universe. But two Stony Brook University professors are part of a project designed to do just that — an effort scientists say is making advances. Researchers in the ...

Observations show the universe appears flat, yet its true size and global shape beyond the observable horizon may remain ...

TACC's Frontera supercomputer helped astronomers develop PRIYA, the largest suite of hydrodynamic simulations yet made of large-scale structures in the universe. Example Lyman-α forest spectra from ...

Space is big. That’s why we call it space. But how big is “big”? That’s relative. When an astronomer says something is nearby, they might mean it’s a few million kilometers away (if they’re talking ...

A new three-volume study explores how quantum physics, gravitation and cosmology may be understood within a unified ...
