Trepanning

​

Trepanning, also known as trepanation, trephination, trephining or making a burr hole is a surgical intervention in which a hole is drilled or scraped into the human skull. The intentional perforation of the cranium exposes the dura mater to treat health problems related to intracranial diseases or release pressured blood buildup from an injury. It may also refer to any "burr" hole created through other body surfaces, including nail beds. A trephine is an instrument used for cutting out a round piece of skull bone to relieve pressure beneath a surface.

"Astronomers have discovered new auroras over Jupiter's four largest moons: Io, Europa, Ganymede, and Callisto, observable at visible wavelengths. The new auroras reveal in greater detail the composition of the thin atmospheres of these Jovian moons, including traces of oxygen and sodium, but only minimal water vapor. "

Never expected that moons could have auroras

"Radiation from a jet of ultrafast particles powered by a supermassive black hole suggests that the particles are accelerated by shock waves propagating along the jet, making them shine with the brightness of 100 billion Suns."
