NGC 4858 is special. Rather than beingness a uncomplicated spiral, it is something called a "galaxy aggregate," which is, every bit the advert suggests, a key galaxy surrounded past times a handful of luminous knots of cloth that seem to stalk from it, extending too violent away too adding to or altering its overall structure.
It is likewise experiencing an extremely high charge per unit of measurement of star formation, maybe triggered past times an before interaction amongst to a greater extent than or less other galaxy. As nosotros encounter it, NGC 4858 is forming stars too thence frantically that it volition piece of occupation upwardly all of its gas long before it reaches the destination of its life. The coloring of its brilliant knots indicates that they are formed of hydrogen, which glows inwards diverse shades of brilliant scarlet every bit it is energized past times the many young, hot stars lurking within.
This scene was captured past times the NASA/ESA Hubble Space Telescope's Wide Field Camera iii (WFC3), a powerful photographic goggle box camera designed to explore the development of stars too galaxies inwards the early on universe.
