Winds from black holes that PUSH gas out into the cosmos may come to stop dwarf galaxies making as many stars

Google Science Feeds - Mon, 10/14/2019 - 17:42
Galaxies which have a black hole at their centre may be slower to create stars because they produce winds which push vital gas into intergalactic space. Researchers were 'surprised' by the strength of the winds produced by the black holes, which are ...

Black hole caught flickering violently WITHIN our galaxy

Google Science Feeds - Mon, 10/14/2019 - 16:43
A black hole located within Earth's Milky Way galaxy is voraciously consuming its neighboring star with such ferocity that it is literally flickering with visible light, in what is perhaps the cosmic equivalent of drooling. The black hole, named MAXI J1820+070, ...

How well has China's ultra low-emissions policy worked?

Google Science Feeds - Mon, 10/14/2019 - 16:35
In 2014, China introduced an ambitious policy to rapidly reduce air pollution from coal-fired power stations. How well did that work? A paper published in Nature Energy last week analyzed data from pollution monitoring systems and found dramatic changes.
