How did the Butterfly Nebula get its wings? It"s complicated
Planetary nebulae form when red giant stars expel their outermost layers as they run out of helium fuel—becoming hot, dense white dwarf stars that are roughly the size of Earth. The material that was shed, enriched in carbon, forms dazzling pattern.....»»

Genetic analysis uncovers shared evolutionary history of fish fins and vertebrate limbs
All vertebrates have the same basic body plan: Head, spine, four appendages. Those appendages vary greatly in size, shape, and function, of course—from fins to wings, arms, and legs—but a new genetic analysis shows that genes that control develop.....»»

Hubble images colorful planetary nebula ringed by hazy halo
NGC 2438 is a planetary nebula, formed after the death of a Sun-like star. The medium-sized star would have expelled its outer layers of gas into space as it died, leaving behind a white-dwarf core. A halo of glowing gas over 4.5 light-years across s.....»»
