After analyzing four years of Kepler space telescope observations, astronomers from the University of Toronto, and of the University of Cambridge have given us our clearest understanding yet of a class of exoplanets called “warm Jupiters”, showing that many have unexpected planetary companions

Gravitational vortex provides new way to study matter close to a black hole

An international team of astronomers has proved the existence of a ‘gravitational vortex’ around a black hole, solving a mystery that has eluded astronomers for more than 30 years. The discovery will allow astronomers to map the behaviour of matter very close to black holes. It could also open the door to future investigation of Albert Einstein’s general relativity.

With its very first observation, the Hitomi X-ray observatory has discovered that the gas in the Perseus cluster of galaxies is much less turbulent than expected. This is a surprise because the Perseus cluster is home to NGC 1275, a highly energetic active galaxy.
