In an extraordinary leap forward for astrophysics, astronomers have achieved a momentous breakthrough with the first direct ...

Matter in intergalactic space is not randomly scattered - it forms a vast network of filamentary structures that make up the ...

These cosmic filaments contain 12 trillion solar masses of 10-million-degree gas, helping solve the "missing matter" mystery.

Astronomers have captured an unprecedented image of the galaxy cluster Abell 2255, revealing intricate, radio-emitting tendrils that stretch for over 360,000 light-years across intergalactic space.

Abell 2255 is a cluster containing between 300 and 500 constituent galaxies, many of which are merging. It's located around ...

Astronomers have discovered a huge filament of hot gas bridging four galaxy clusters. At 10-times as massive as our galaxy, the thread could contain some of the Universe’s ‘missing’ matter, addressing ...
