A new image of the Eta Carinae system captured by the Hubble space telescope offers new details of this truly special star system. The Wide Field Camera 3 (WFC3) instrument has in fact made it possible to observe the area in ultraviolet light as well revealing the glow of the magnesium embedded in the hot gas in places where it wasn’t seen before. Every new detail helps to understand the violent processes observed from the Earth for the past two centuries, since the event known as the Great Eruption began.
