New research has offered a tantalizing new possibility in the realm of interstellar molecules and diffuse interstellar bands: these mysterious molecules may be silicon-capped hydrocarbons like SiC3H, SiC4H and SiC5H. The team of scientists presents data and theoretical arguments to back that hypothesis in The Journal of Chemical Physics.

Hubble Spots Spiral Bridge of Young Stars Linking Two Ancient Galaxies

p1426aw.jpg

NASA's Hubble Space Telescope has photographed an unusual structure 100,000 light-years long, which resembles a corkscrew-shaped string of pearls and winds around the cores of two colliding galaxies. The unique structure of the star spiral may yield new insights into the formation of stellar superclusters that result from merging galaxies and gas dynamics in this rarely seen process.
