Juno spacecraft reveals a complex Jupiter-NASA’s Juno spacecraft swooped within 5000 kilometres of Jupiter’s cloud tops on August 27, 2016, giving scientists their first intimate look at the gas giant. The data are revealing surprising details about Jupiter’s gravity, powerful magnetic field and ammonia-rich weather system. The findings, which appear in two studies in the May 26thScience, suggest researches may not only revamp their views of Jupiter but also their ideas about how planetary systems from and evolve.
Barrier reef suffers huge coral loss- According to officials, Australia’s Great Barrier Reef has lost nearly a third of its corals in the past year.
