The universe has two types of matter. There is an invisible dark matter, known only because of its gravitational effects on large scale. And there is a common matter, such as gas, dust, stars, planets. Scientists estimate that the average matter is only about 15% of all matter, but they have long tried to document where it is all, about half of which is still unknown. With the help of powerful rays from which radio from 69 locations of the cosmo…

Mysterious gas: Only a few days ago astronomers reported the detection of "missing" cosmic matter, now a second team provides further confirmation. Because for the first time they have detected and measured the matter in a huge filament of hot gas, which connects four clusters of galaxies. The filament extends over 23 million light years and is ten million degrees hot. Its properties and gas structure are in line with the predictions of the stan…

Astronomers have discovered a huge filament of hot gas connecting four clusters of galaxies within Shapley's superamas. Ten times more massive than our galaxy, this filament appears to contain part of the "missing" barionic matter of the Universe, confirming the predictions of cosmological simulations that were going in this direction. They publish their discovery in Astronomy&Astrophysics.It is recalled that today, more than a third of the norm…
