Gas cloud collisions during galaxy mergers compress interstellar material, triggering new star formation, as observed in interacting systems studied by NASA and reported by Universe Today.

Gas density is frequently estimated indirectly by gas pressure sensors. Because the pressure in a tightly sealed compartment fluctuates greatly with temperature, such systems require temperature ...

The "missing baryons problem," the discrepancy between the predicted and observed amount of normal matter in the universe, has persisted for over two decades. Scientists have previously located only ...

In the mid-2010s it became common to say that natural gas would be a bridge fuel to a zero-carbon future, in which solar, wind and other renewable technologies provide all of our energy without any ...

Powder is a collection of single solid particles, which in most cases may be considered a basic unit. Powder is typically comprised of solid particles, interparticle voids, as well as open and closed ...
