Three planets -- each orbiting its own giant, dying star -- have been discovered by an international research team led by a Penn State University astronomer.

An international team, including NASA-funded researchers, using radio telescopes located throughout the Southern Hemisphere has produced the most detailed image of particle jets erupting from a supermassive black hole in a nearby galaxy.

Astronomers at the European Southern Observatory (ESO) have discovered five planets orbiting a star in what is being called "the biggest discovery of so-called exoplanets since the first was logged 15 years ago."

An international group of astrophysicists has determined that a massive planet outside our Solar System is being distorted and destroyed by its host star – a finding that helps explain the unexpectedly large size of the planet, WASP-12b.

An international team of scientists has observed four super-massive black holes at the center of galaxies, which may provide new information on how these central black hole systems operate.
