*Fourth gravitational wave detection Astronomers have achieved a fourth gravitational wave detection of merging stellar mass black holes. The new discovery was a combined effort between the existing LIGO Laser Interferometer Gravitational-Wave Observatory detectors in Livingston, Louisiana, and Hanford, Washington together with the New European VIRGO detector near Pisa in Italy.

*Discovery of a pitch black planet that eats light. NASA's Hubble Space Telescope has observed a planet outside our solar system that looks as black as fresh asphalt because it eats light rather than reflecting it back into space. This light-eating prowess is due to the planet's unique capability to trap at least 94 percent of the visible starlight falling into its atmosphere.

^New Pluto mission proposal NASA has received a new proposal for a surface mission to Pluto. The new plan would follow on from the highly successful New Horizons spacecraft which undertook an historic close flyby of Pluto its binary partner Charon, and their five moons back in July 2015.

*New Earth Observation satellite The CSIRO has joined a project developing and operating one of the world’s most sophisticated Earth observation satellites. The 430 kilogram Synthetic Aperture Radar remote sensing satellite – known as the NovaSAR -- will launch later this year on an Indian PSLV rocket.

*NROL-42 spy satellite launched An Atlas V rocket has blasted into orbit from the Vandenberg Air Force Base in California carry a secret National Reconnaissance Office satellite. The NROL-42 mission blasted off into black late-night skies which seemed more than appropriate for such a clandestine flight.

*Russian Navigation satellite launched Russia has launched the latest member of its Glonass satellite navigation system. The Russian Military Air and Space Forces Soyuz 2.1b rocket carrying the Glonass-M satellite was launched from the Plesetsk Cosmodrome north of Moscow.

*The Science Report A new clue in combating aggressive brain tumours. A nine week expedition to the lost continent of Zealandia returns to port in Hobart. A new study finds that teens get their bad moods from their friends. New evidence claims modern humans were settling in the America’s some 13 thousand years ago. People who tend to trust their intuition are more likely to hold inaccurate beliefs.
