Look up at the night sky and it is easy to believe that stars and galaxies are where the universe keeps almost all of its substance. Precision measurements of the cosmos tell a different story. Most ...

Nearly all stars are found inside or around galaxies, because that's where the conditions are right for stars to form. Within galaxies, stars form inside cold, dense molecular gas clouds like those ...

Add Yahoo as a preferred source to see more of our stories on Google. Half The Universe's Matter Was Missing. Astronomers Just Found It. A new analysis of the sky has finally confirmed where the ...

"By reproducing relativistic plasma conditions in the lab, we can measure processes that shape the evolution of cosmic jets and better understand the origin of magnetic fields in intergalactic space." ...

"They look like a [developing] butterfly or something in this young state that kind of grows wrapped in some sort of gas that ...

Using CERN’s Super Proton Synchrotron, researchers generated plasma fireballs to simulate blazar jets. The beams stayed stable, suggesting plasma instabilities aren’t responsible for missing gamma ...

The vast majority of stars form and reside within galaxies due to the presence of cold, dense molecular gas clouds conducive to star formation. True intergalactic space, characterized by low-density ...
