NGC 604 is an H II region inside the Triangulum Galaxy. It was discovered by William Herschel on September 11, 1784. It is among the largest H II regions in the Local Group of galaxies; at the galaxy's estimated distance of 2.7 million light-years, its longest diameter is roughly 1,520 light years (~460 parsecs) (14.38031 exameters), over 40 times the size of the visible portion of the Orion Nebula. It is over 6,300 times more luminous than the Orion Nebula, and if it were at the same distance it would outshine Venus. Its gas is ionized by a cluster of massive stars at its center with 200 stars of spectral type O and WR, a mass of 105 solar masses, and an age of 3.5 million years; however, unlike the Large Magellanic Cloud's Tarantula Nebula central cluster (R136), NGC 604's one is much less compact and more similar to a large stellar association.

 NGC 604 is an H II area inside the Triangulum Galaxy. It was discover by William Herschel on September 11, 1784. It is among the largest H II regions in the Local Group of galaxy; at the galax's estimated distance of 2.7 million light - years, its long diameter is roughly 1,520 light old age (~460 parsecs) (14.38031 exameters), over 40 times the size of the visible share of the Orion Nebula. It is over 6,300 times more luminous than the Orion Nebula, and if it were at the like distance it would outshine Venus. Its gas is ionized by a cluster of massive stars at its center with 200 stars of spectral character O and WR, a mass of 105 solar masses, and an age of 3.5 million long time; however, unlike the Large Magellanic Cloud's Tarantula Nebula central bunch (R136), NGC 604's one is much less compendious and more similar to a large stellar association.
