A Rutgers-led team of scientists has uncovered evidence of how galaxies expand by tracing the invisible scaffolding of the ...

Configurations like these, known as Einstein crosses, typically consist of four distinct points of light. This particular ...

For a quarter century, cosmology has leaned on one framework to explain how the universe expands. Known as the ΛCDM model, it ...

Scientists at Rutgers and collaborators have traced the invisible dark matter scaffolding of the universe using over 100,000 ...

Let me first tell you how mysterious dark energy is. Einstein added a cosmological constant to his equations to keep the universe 'static,' but later regretted it, calling it the biggest mistake of ...

The "dark universe detective" space telescope Euclid has discovered its first Einstein ring in the process, learning about dark matter at the heart of a distant galaxy.
