*New study challenges popular theory about dwarf galaxies Existing hypothesis about how dwarf galaxies are spread across the universe is being challenged following the discovery of a plane of dwarf galaxies orbiting around Centaurus A. The findings challenge the long-held idea there are thousands of dwarf galaxies in all directions around large galaxies -- like bees swarming around a hive.

*A new theory to explain the discovery of matter in hostile black hole winds Scientists have developed a new hypothesis to try to explain the origins of molecules discovered in the destructive cosmic outflows produced by supermassive black holes. If correct it could explain how stars form in extreme environments. 

*Arianespace places satellites into wrong orbits Arianespace has set up an independent investigation commission chaired by ESA’s General Inspector after its first launch for the year placed two telecommunications satellites into the wrong orbits.

*New eye in the sky to watch for enemy missiles The United States has launched a new missile early warning satellite from the Cape Canaveral Airforce base in Florida.

*China launches three new spy satellites Beijing has launched three more signals intelligence spy satellites for the Chinese military. Beijing describes the satellites as part of a remote sensing mission used to conduct electromagnetic and other experiments. What they’re actually doing is searching for signals intelligence data from foreign powers.
