A new study suggests Uranus’ moon Miranda may harbor a water ocean beneath its surface, a finding that would challenge many assumptions about the moon’s history and composition and could put it in the company of the few select worlds in our solar system with potentially life-sustaining environments.

Though there are no firm plans for a crewed mission to Mars, we all know one’s coming. Astronauts routinely spend months at a time on the ISS, and we’ve learned a lot about the hazards astronauts face on long missions. However, Mars missions can take years, which presents a whole host of problems, including astronaut […]

A team of scientists have invented a new technique to determine the dynamics of microscopic interacting particles by using image recognition to count the number of particles in an imaginary box. By changing the size of the observation box, such counting enables the study of the dynamics of the collective system, even for a dense […]
While many smoking rooms in U.S. airports have closed in recent years, they are still common in other airports around the world. These lounges can be ventilated, but how much does it actually help the dispersion of smoke?

Water and oil, and some other simple fluids, respond in the same way to all levels of shear stress. These are termed Newtonian fluids, and their viscosity is constant for all stresses although it will vary with temperature. Under different stresses and pressure gradients, other non-Newtonian fluids exhibit patterns of behavior that are much more […]

The Island of Sardinia, west of the Italian Peninsula in the Mediterranean Sea, holds many ancient secrets. Today, ancient astronaut theorists are most interested in the monumental tombs and other sites that seem to indicate a race of giants who used advanced technology. If not giants, it’s still unexplainable using […]
