Old supernova remnants are cooler and thus can emit some optical radiation, but the ratios of the strengths of one spectral line to another (like sulfur to hydrogen) are different from those seen ...

Two astrophysicists have finally solved a 20-year-old astrophysical puzzle concerning the lower-than-expected amounts of the element sulphur found in Planetary Nebulae (PNe) in comparison to ...

Some diffuse nebulae are more obvious not for how they reflect or emit light, but how they block it. Perhaps the most famous example of a dark nebula, the Horsehead Nebula, is visible only as a ...
