Multi-wavelength observations of the Ophiuchus star-forming region reveal interactions between clouds of star-forming gas and radionuclides produced in a nearby cluster of young stars. The top image (a) shows the distribution of aluminum-26 in red, traced by gamma-ray emissions. The central box represents the area covered in the bottom left image (b), which shows the distribution of protostars in the Ophiuchus clouds as red dots. The area in the box is shown in the bottom right image (c), a deep near-infrared color composite image of the L1688 cloud, containing many well known prestellar dense-gas cores with disks and protostars.

An artist’s impression of a thermonuclear supernova: the material ejected by the supernova will initially expand very rapidly, but then gradually slow down, forming an intricate giant bubble of hot glowing gas; eventually, the charred remains of the white dwarf that exploded will overtake these gaseous layers, and speed out onto its journey across our Milky Way Galaxy.

An artist’s impression of the collision of two stars, like the ones that formed CK Vulpeculae. The inset illustrates the inner structure of one red giant before the merger. A thin layer of 26Al (brown) surrounds a helium core. An extended convective envelope (not to scale), which forms the outermost layer of the star, can mix material from inside the star to the surface, but it never reaches deep enough to dredge 26Al up to the surface. Only a collision with another star can disperse 26Al. Image credit: NRAO / AUI / NSF / S. Dagnello.
