New observations support the idea that hot, diffuse threads of gas called cosmic filaments connect clusters of galaxies ...

A vast filament of gas stretching across the cosmos may help solve the mystery of the Universe’s missing matter. Astronomers ...

Two studies fill in gaps about the cosmos’s ordinary matter. One maps it all, even the “missing matter.” The other details one of its hiding spots.

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 ...

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 ...

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

The team used two X-ray space telescopes: the Japanese Suzaku and the European XMM-Newton. They published their findings recently in the journal Astronomy and Astrophysics. The astronomers analysed a ...

Astronomers using the NASA/ESA Hubble Space Telescope have studied a giant filament of dark matter in 3-D for the first time. Extending 60 million light-years from one of the most massive galaxy ...

A massive solar filament erupted today (May 7), producing a stunning display that spanned the sun's eastern limb and reached deep into the solar disk. Filaments are cooler, dense ribbons of solar ...
