Gravitoelectromagnetism
Videos
Gravitoelectromagnetism, abbreviated GEM, is a set of formal analogies between the equations for electromagnetism and relativistic gravitation. More specifically, it is an analogy between Maxwell's fi

An astrophysical jet is an astronomical phenomenon where ionised matter is expelled at high velocity from an astronomical object, in a pair of narrow streams aligned with the object's axis of rotation
The starburst galaxy Centaurus A, with its plasma jets extending over a million light years, is considered as the closest active radio galaxy to Earth. The 870-micron submillimetre data, from LABOCA on APEX, are shown in orange. X-ray data from the Chandra X-ray Observatory are shown in blue. Visible light data from the Wide Field Imager (WFI) on the MPG/ESO 2.2 m telescope located at La Silla, Chile, show the background stars and the galaxy's characteristic
