One of the biggest successes appeared to be a collision of galaxy clusters called the Bullet Cluster. It provided one of the most spectacular and intuitive indications that seemed to show that ...

The Bullet Cluster is a massive collection of two large groups of galaxies some 3.8 billion light-years distant. The two groups appear to have collided in one of the most energetic events known in ...

Known as the Bullet Cluster, it showcases two galaxy clusters that have recently collided. The individual galaxies present within the clusters, like two guns filled with bird shot fired at one ...

The scientists used data from NASA’s Hubble Space Telescope and Chandra X-ray Space Observatory to study galaxy cluster mergers, particularly the “bullet cluster” collision, a projectile ...

That leads us to the “Bullet Cluster,” one of the most important systems in astronomy. First described in 2006, it’s actually a pair of galaxy clusters observed in the act of colliding.

This collision, which has been collectively nicknamed the Bullet Cluster, consists of a smaller “bullet” galaxy cluster, which has passed through an exceptionally large galaxy cluster. The trick to ...

Slow decay Scientists proposed the half-life — about 150,000 times longer than the current age of the universe — after looking at X-rays from the Bullet Cluster, a cosmic collision of galaxies ...

Observations from Europe's XMM-Newton X-ray space telescope reveal that the bullet galaxy blasted through a galaxy cluster called Abell 4067 at 814 miles (1,310 kilometers) per second. The cosmic ...

The bullet-shaped clump on the right is hot gas from one cluster, which passed through the hot gas from the other larger cluster. Other telescopes were used to detect the bulk of the matter in the ...

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 ...
