    The Zwicky Transient Facility sees “first light”: a new era in the study of the dynamic sky

    The Zwicky Transient Facility is now ready to start operations. A new robotic camera with the ability to capture hundreds of thousands of galaxies in a single shot has taken its first image of the sky. The recently installed camera is part of a new automated sky-survey project based at the Palomar Observatory in California and a revolutionising tool for the study of rapidly varying cosmic phenomena

    The most energetic transient events : supernovae or stars disrupted by black holes?

    A new type of energetic transient has been discovered in the center of active galaxies. There are two potential causes for these events : the explosion of a massive star or the tidal disruption of a star by the galaxy's central, supermassive black hole.

    Gravitational waves from the merger of two neutron stars have been detected for the first time. Scientists around the world pinpointed the source to a galaxy 130 million light years away.
