Physicists from the ALPHA Collaboration at CERN have detected the Lyman-alpha transition — when the hydrogen electron transitions between the lowest-energy (1S) level and the higher-energy (2P) level, emitting or absorbing ultraviolet light of 121.6 nm wavelength — in the antihydrogen atom, the antimatter counterpart of hydrogen.

Neutron stars are the smallest, densest stars in the Universe. True to their name, neutron stars are composed almost entirely of neutrons. Duer et al suggest that some properties of neutron stars may be influenced not only by their multitude of densely packed neutrons, but also by a substantially smaller fraction of protons -- positively charged particles that make up just 5% of a neutron star. This is an illustration of a neutron star. Image credit: Casey Reed, Penn State University.

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.
