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 Bullet Cluster, named for its distinctive shape, has long been considered a smoking gun for the existence of dark matter in space. What makes this cluster famous isn’t the violence of it all. It’s ...

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 ...

Using a technique called sonification, NASA has generated two new pieces of music based on data from notable celestial destinations: the Bullet Cluster and the Crab Nebula. As with previous ...

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 ...

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 ...
