A swarm of galaxies called the Bullet Cluster is the biggest, best natural laboratory for studying dark matter that astronomers have ever seen ...

The Bullet Cluster as seen by the James Webb Space Telescope (JWST) consists of a larger cluster of galaxies (left) and a smaller cluster (right). The hot gas seen by the Chandra X-ray Observatory is ...

Dark matter is a type of matter that does not emit, absorb, or reflect light, making it invisible to telescopes. Israeli scientists have outlined a groundbreaking method to study dark matter, ...

A new study from Tel Aviv University has predicted, for the first time, the groundbreaking results that can be obtained from ...

Faint hydrogen signals from the cosmic Dark Ages may soon help determine the mass of dark matter particles. Simulations suggest future Moon-based observatories could distinguish between warm and cold ...

Astronomers studying a rare Einstein Cross stumbled upon an impossible “fifth image” that shouldn’t exist — and it revealed ...

Scientists from Rutgers have reported their discovery of a rare "Einstein cross" that helped them localize a large patch of ...

NASA has been studying the galaxies in the Coma Cluster after discovering a galaxy with the same shape of a UFO. Dark matter is once again being considered.

A chance configuration of objects arrayed across deep space has just revealed the hiding place of a giant glob of dark matter ...

NASA’s latest discovery in the heart of our galaxy is raising more questions than answers. For the first time, a mysterious dark halo has been observed in the center of the Milky Way, a finding that ...

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.

When searching for the unknown, classic physics wisdom holds that a bigger detector boosts the chances of discovery. A physicist is taking that advice to heart, advancing a bold plan to use none other ...
