Why it's so special: Galaxy clusters act as a magnifying lens, shining light on the faintest and most distant objects — a phenomenon known as gravitational lensing. On the rarest of occasions, galaxy ...

The James Webb Space Telescope (JWST) has provided groundbreaking insights into the Bullet Cluster, a cosmic collision zone located 3.8 billion light-years from Earth. The JWST’s enhanced imaging ...

NASA's James Webb Space Telescope recently zeroed in on the Bullet Cluster—delivering highly detailed images that show a greater abundance of extremely faint and distant galaxies than ever before.

The two clusters of galaxies, called Bullet Cluster, are in the process of moving through each other. The red curves show gravitational measurements of the combined mass that consists of partly the ...

Analysis of the Bullet Cluster, which was formed after two large clusters of galaxies collided, supports the existence of dark matter. X-ray: NASA / CXC / CfA / M. Markevitch et al.; Optical: NASA / ...

Using a combination of powerful observatories in space and on the ground, astronomers have observed a violent collision between two galaxy clusters in which so-called normal matter has been wrenched ...
