Astronomers have made the first direct observation of a spinning black hole twisting the very fabric of spacetime, a ...

Abstract: There have been considerable interests in the lunar-based synthetic aperture radar (LBSAR) for monitoring large-scale geoscience phenomena. However, the signal distortions given rise by ...

When a star gets too close to a black hole, the gravity of the black hole changes what happens next in really big ways. They give us a chance to see h.

The equation of motion of a classical charged particle in a homogeneous, static electromagnetic field is solved exactly in terms of a Lorentz transformation. All higher‐order corrections to the motion ...

Earth is not a still point in space, but a planet hurtling through the cosmos at incredible speeds. This video breaks down the complex layers of our motion: the 66,000 mph orbit around the sun, the ...
