Grand Stellar Nursery NGC 604
Finally decided to stop frustrating myself with some 3D galaxy illustrations and got back to some Hubble processing I've been meaning to do for a while now. Last year, HST finished the PHAT survey of nearby galaxy M33, or the Triangulum galaxy. There are massive mosaics of this available, but the survey also enabled me to create a much more complete image of a nebula which is of particular interest. Let me just quote from Wikipedia since the sentence is so evocative already:
"It is over 6,300 times more luminous than the Orion Nebula, and if it were at the same distance it would outshine Venus."
Impressive as it is, the Orion Nebula can't compete with NGC 604. Orion is just lucky to be so close to us. NGC 604 is where the star-formation party is really at. It only takes a few million years for light from this cosmic rave party to reach us.
Note that the PHAT data alone wasn't enough to make this image. I went back and made use of older WFPC2/WFC data to really make this cloud of gas pop in bright pink colors. Otherwise it would have looked blueish since the nebula is most apparent within the F475W observations.
This image was made possible by the following Hubble programs:
Red: WFC3/IR F160W
Yellow-Green: ACS/WFC F814W
Cyan: ACS/WFC F475W
Blue: WFC3/UVIS F336W
F673N, F658N, and F656N combined together into a pinkish "screen" layer
North is NOT up. It is 90° clockwise from up.
