Astrophysicists have discovered a series of telltale shell-like formations of stars in the vicinity of the Virgo constellation, evidence of a radial merger between a dwarf galaxy and the Milky Way, ...

Researchers previously focused on the roles of these complex structures in resisting pressure on the shell, but new researchers provide evidence for a different hypothesis. Complex sutures, they found ...

Abstract: Pressure vessels are closed structures containing liquids or gases under pressure. Familiar examples include fuel tanks, pipes, and pressurized cabins in aircraft and space vehicles. When ...
