Europa’s Plate Tectonic Activity Is Unlike Earth’s

The moon of Jupiter has likely experienced intermittent, regional plate tectonic activity in the past, although the plates are currently dormant.

Researchers discover black hole jet pointing at Earth

A group of international astronomers, including scientists from the University of Southampton and the Massachusetts Institute of Technology (MIT), have discovered a signal that is likely from a relativistic jet of matter, streaking out from a supermassive black hole at close to the speed of light.

A titanic collision could have formed the moon within hours, new simulation shows

Bob McDonald's blog: A Mars-sized object hitting a proto-Earth formed a new moon surprisingly quickly

NASA Goddard Scientists Create Black Hole Jetswith NCCS Discover Supercomputer

New simulations carried out on the NASA Center for Climate Simulation (NCCS) Discover supercomputer show how weaker, low-luminosity jets produced by a galaxy's monster black hole interact with their galactic environment. Because these jets are more difficult to detect, the simulations help astronomers link these interactions to features they can observe, such as various gas motions and optical and X-ray emissions.
