What It Looks Like When A Massive Black Hole Devours A Star
In the figure we see a cross section of what happens when the material from the disrupted star is devoured by the black hole. An accretion disk is formed (disk) by the material. There is too much material for it to pass into the black hole at once. It is heated up in the process and emits vast amounts of light and radiation, visible from Earth (Double arrow).

ETH Astronomers Identify Six 'Dark Galaxy' Candidates
One of the new dark-galaxy candidates, identified through a combination of spectral information (left) and images reflecting the emission of gas (middle) and stars (right). The position of the dark-galaxy candidate is marked by the red circle. R. A. Marino / MUSE

Scientists Discover New Magnetic Process in Turbulent Space
In a turbulent magnetic environment, magnetic field lines become scrambled. As the field lines cross, intense electric currents (shown here as bright regions) form and eventually trigger magnetic reconnection (indicated by a flash), which is an explosive event that releases magnetic energy accumulated in the current layers and ejects high-speed bi-directional jets of electrons.

Scientists Discover Gigantic Solar Rossby Waves on the Sun
Vortex on the sun: The Rossby waves propagate in the direction opposite to rotation of the Sun. Near the equator, their amplitude (the maximum deflection of the vibration, so to speak) is the greatest. © MPS / NASA / HormesDesign
