Mystery, Nature’s Awe. Blue hole, under ocean? Black hole, sky above sky
The first reports of blue holes came from fishermen and recreational divers, not scientists or researchers. In general, the holes appear to host diverse biological communities full of marine life, including corals, sponges, mollusks, sea turtles and sharks.
The glowing mystery hole, about 155 feet below the water’s surface, is similar to the sinkholes seen on solid land, according to the National Oceanic and Atmospheric Administration.
Black hole at the centre of the massive galaxy M87, about 55 million light-years from Earth, as imaged by the Event Horizon Telescope (EHT). The black hole is 6.5 billion times more massive than the Sun.
In March 2018, this black hole’s corona briefly shined extra bright, a 40-fold increase in brightness. After the AGN lit up, it dimmed suddenly. The black hole at its center — which can be seen best using X-ray telescopes — seemed to get 10,000 times less bright in less than a year.
