Which galaxies are the poorest in gas and dust? Which galaxies have the fewest bright stars? Is it accurate to describe the physical universe as composed of only matter and energy? If most of the light travels through a material, the material is said to be what?
“The hunt for continuous gravitational waves is one of the top challenges in gravitational wave science,” said Andrew Melatos, an OzGrav Chief Investigator whose research group at the University of Melbourne has been chasing these tiny signals for more than a decade. “Pulsars ar...
the collapsed remnants of burned-out stars, and it produces mind-boggling densities—one teaspoon of such material weighs several hundred billion kilograms.
black holes are even denser, but they are certainly far from normal. In fact, scientists believe that the strongest material in the Universe, referred to as “nuclear pasta,” can be found deep inside the crust ofneutron stars.
Two undergraduates at San José State University have discovered two galaxies that are the densest known. Similar to ordinary globular star clusters but a hundred to a thousand times brighter, the new systems have properties intermediate in size and lumi
