NGC 4666

NGC 4666 is a spiral galaxy in the constellation Virgo. It is noteworthy for its vigorous star formation, which creates an unusual “superwind”[3] of out-flowing gas. This wind is not visible at optical wavelengths, but is prominent in X-rays, and has been observed by the ESA XMM-Newton space telescope.[4]
