Is this galaxy too hot for its own good?S

Check out this brilliant image of spiral galaxy NGC 2841, from the Hubble Space Telescope's Wide Field Camera 3. This galaxy has an unusually low rate of star creation — you can tell by the absence of the pinkish glow of emission nebulae, which would indicate new star birth. What's going on? NASA explains:

It is likely that the radiation and supersonic winds from fiery, super-hot, young blue stars cleared out the remaining gas (which glows pink), and hence shut down further star formation in the regions in which they were born. NGC 2841 currently has a relatively low star formation rate compared to other spirals that are ablaze with emission nebulae.
