Last week, the Japanese meteorological satellite Himawari-8 snapped a pretty cool image of Australia from space. The image shows an enormous gravity wave sweeping through the atmosphere off the ...

A research team has discovered a new type of sound wave: the airborne sound wave vibrates transversely and carries both spin and orbital angular momentum like light does. The findings shattered ...

Since energy is conserved (the gravitational force is conservative), we can use the work/energy equation to determine the speed of the satellite as a function of the distance R from O to P. Since the ...

All binary systems — massive bodies orbiting around each other, irrespective of what the bodies are — generate gravitational waves. Roughly speaking, the strength of the gravitational waves depends on ...

Using the supersharp radio “vision” of the National Science Foundation’s Very Long Baseline Array (VLBA), astronomers have made the first detection of orbital motion in a pair of supermassive black ...
