Video from the U.S. Geological Survey showed Kilauea volcano spewing lava more than 800 feet into the air in its latest eruption on Hawaii's Big Island. USGS said the eruption began around 4:15 p.m.

Learn the physics behind Ja Morant's incredible 360 layups! Discover the science of angular momentum and how it makes his moves possible.

The momentum of an object is the product of its mass and its velocity. There is an equivalent law for rotating objects. A rotating object tends to remain rotating with a constant angular momentum ...

Close-in, planet-like formation followed by scattering to the current location would likely disrupt the disk and is disfavored. Furthermore, we find no additional companions, though we could detect ...

Abstract: An Eulerian finite-difference method solving the Vlasov equation is developed with a static, non-uniform momentum grid. The computational cost of this transformation differs negligibly from ...

We derived rotation curves from our observations, which we use here to construct mass models. We model the total mass distribution as the sum of a generalized Navarro-Frenk-White (NFW) dark matter ...
