An international group of researchers has discovered the first 'lighting' from a black hole, with variations in brilliance more powerful than ever observed in an extragalactic object. The emission, the researchers suggest in their study, "is associated with pulsar-like particle acceleration by the electric field across a magnetospheric gap at the base of the radio jet."

The new MUSE instrument on ESO's Very Large Telescope has provided researchers with the best view yet of a spectacular cosmic crash. The new observations reveal for the first time the motion of gas as it is ripped out of the galaxy ESO 137-001 as it ploughs at high speed into a vast galaxy cluster. The results are the key to the solution of a long-standing mystery — why star formation switches off in galaxy clusters.

Research scientists have demonstrated a new technique for generating electrical energy. The new method can be used in harvesting energy from mechanical vibrations of the environment and converting it into electricity. Energy harvesters are needed, for example, in wireless self-powered sensors and medical implants, where they could ultimately replace batteries. In the future, energy harvesters can open up new opportunities in many application areas such as wearable electronics.

Astronomers have used radio telescopes in Australia and Chile to see inside the remains of a supernova. The supernova, known as SN1987A, was first seen by observers in the Southern Hemisphere in 1987 when a giant star suddenly exploded at the edge of a nearby dwarf galaxy called the Large Magellanic Cloud. In the two and a half decades since then the remnant of Supernova 1987A has continued to be a focus for researchers the world over, providing a wealth of information about one of the Universe's most extreme events.
