Known as the Bullet Cluster, it showcases two galaxy ... not with the intra-cluster matter. Hence, dark matter must exist. According to the standard line of reasoning, the clusters are composed ...

Dark matter just got a shade more mysterious ... Observatory to study galaxy cluster mergers, particularly the “bullet cluster” collision, a projectile-shaped structure resulting from two ...

Ever since, the search for other lines of evidence for dark matter has been an interesting one. One of the biggest successes appeared to be a collision of galaxy clusters called the Bullet Cluster.

Whereas for me, I say dark matter doesn't exist. It's the gravity that's changed." Using images of the Bullet Cluster made by the Hubble, Chandra X-ray and Spitzer space telescopes and the ...

One of the most famous smoking guns for dark matter is the Bullet cluster (see image above). Here, a small galaxy cluster swept through a larger one about 100 million years ago. The galaxies ...

The Bullet Cluster, and a myriad of observations of similar objects, tie together our picture of dark matter along with other lines of evidence like stellar velocities in galaxies, the cosmic ...

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 another ...

Such decoupling of dark and normal matter has been seen before, most famously in the Bullet Cluster. In that collision, the hot gas can be seen clearly lagging behind the dark matter after the two ...

collisions between clusters of galaxies provide a great testing ground. We learned quite a bit about dark matter from observations of the Bullet Cluster, and now a new study provides further ...
