- Lord of the Rings: Astronomers Pinpoint the Location of a Mysterious Neutron Star with Superlative Rings of X-ray Light
- 23 June 2015 — The largest and brightest set of cosmic rings resulting from echoes of X-ray light has been discovered by a science team that includes a Penn State astronomer. The team used NASA's Chandra X-ray Observatory to discover the beautiful and extraordinary rings, which were produced by an intense burst of energy from a neutron star. Rings of this type give astronomers a rare chance to determine the distance from Earth to an object in our Milky Way Galaxy.

- A First: Exoplanet smaller than Earth gets its size and mass measured
- 16 June 2015 — A team of astronomers has measured the mass and size of a Mars-sized planet orbiting a red dwarf star about 200 light years from our solar system. The planet, named Kepler-138b, is the first exoplanet smaller than the Earth to have both its mass and its size measured. A paper by the team, which includes astronomers at Penn State University, NASA Ames Research Center, the SETI Institute, and the University of Chicago, will be published in the journal Nature on 18 June 2015.
