Because it doesn't interreact with light or electromagnetism, dark matter exists to us only through its influence on visible ...

How astronomers used gravitational lensing, a space-time trick predicted by Einstein, to detect a black hole measuring 30 billion times the mass of the sun.

This initiative is in turn driven by my frustration with the status quo, namely the notion of dark matter’s existence despite ...

To understand gravitational lensing and dark matter, James Jee, a professor at Yonsei University, says to think of a pond ...

Webb’s new images of the Bullet Cluster reveal the most detailed dark matter map yet, shedding light on cosmic collisions and ...

NASA's James Webb Space Telescope recently zeroed in on the Bullet Cluster—delivering highly detailed images that show a ...

The James Webb telescope has made another stunning discovery -- this time of a massive planet that could potentially sustain ...

"We will push the limits of what we can observe, and use every gravitational lens we detect with Roman to pin down the ...

For years, scientists have worked to chart the universe’s massive structure, aiming to test key models of cosmology. These ...

A new paper claims astronomers discovered an ultramassive black hole heavier than any other black hole we've ever measured.

Researchers say there are far more supermassive black holes out there than we previously suspected, and they're starting to ...
