Astronomers have discovered a rare group of five dwarf galaxies located relatively close to Earth; these galaxies exist in a near-perfect alignment, resembling a string of cosmic pearls in the sky.

NEW YORK (AP) — NASA’s Hubble Space Telescope got a rare look at the aftermath of two cosmic collisions — and helped scientists solve a decades-old mystery. National Science Foundation reverses ...

An astronomer at the University of Hawaiʻi at Hilo is using data from the Canada–France–Hawaiʻi Telescope (CFHT) on Maunakea to help reconstruct a slow-motion cosmic collision, one that has been ...

Cosmic strings are artifacts of what the universe looked like in the moments before it rapidly changed from a high-energy to low-energy environment—the Big Bang. Today, scientists believe cosmic ...

The international network of gravitational wave detectors LIGO in the United States, Virgo in Italy and KAGRA in Japan (LVK) announced the publication of an updated catalogue of all gravitational ...

Cosmic strings are hypothesised one-dimensional topological defects formed during symmetry-breaking phase transitions in the early Universe. As these strings evolve, they intersect and form loops ...
