An international team of astronomers has identified two new tidal streams in the Andromeda Galaxy, the remnants of dwarf galaxies consumed by our large galactic neighbor. Analysis of the stars in ...

We know that interstellar objects occasionally visit our solar system. So far, we have only discovered two interstellar objects (ISOs), but that's mainly because we can only distinguish them from ...

A day before world leaders meet at COP26 to discuss the importance of clean energy, scientists from across the UK say that harnessing the power of the ocean's tidal streams can provide a predictable ...

Tidal power is a fantastic source of clean, predictable energy – if you can harness it. It's proven immensely difficult due to a range of factors, but engineering giant SKF says it's making major ...

The thesis and its corollary have been proposed by Campbell that streams flowing essentially at and below tidal level have no power to meander, and that meanders in such streams are indicative of ...

In a tidal disruption event, an unfortunate star passes too close to a dormant supermassive black hole and gets torn apart by tidal forces, feeding the black hole for a short time. Astronomers use ...
