Sleep Plan

 Voracious, bizarre, and bewitching, supermassive black holes are thought to haunt the mysterious hearts of perhaps every large galaxy in the observable Universe--including our own Milky Way. Our Galaxy's resident dark heart is named Sagittarius A*--Sgr A* , for short (pronounced saj-a-star), and it is dormant now, but still manages to awaken from its slumber now and then to dine on an unlucky star or cloud of gas that has wandered too close to its gravitational embrace. Sgr A *, despite its currently quiet nature, still has enough "life" left to surprise astronomers with a sudden and dramatic episode of turbulent activity. In October 2019, a team of astronomers announced that they had found evidence of a recent cataclysmic flare that exploded so far out of the Milky Way that its destructive influence was felt 200,000 light-years from its origins. This enormous, expanding beam of energy erupted close to Sgr A* only a "mere" 3.5 million years ago--which is only a

 With its enticingly secretive surface blanketed by a dense golden-orange fog, Titan--the largest moon of Saturn--was long regarded as a mysterious, frigid moon-world. However, the Cassini-Huygens mission changed all that when the Huygens lander floated down to the foggy moon's surface in 2004, and gazed at Titan's well-hidden face behind its strange orange mask. Although the Cassini-Huygens mission ended in 2017, planetary scientists are still pouring over the treasure trove of information that it sent back to Earth before it was intentionally destroyed by mission scientists. In October 2019, a team of scientists led by a University of Hawaii (Manoa) chemistry professor and researcher, announced that they have been able to provide answers to important questions about the strange surface of Titan. The researchers say that they have unraveled the origin and chemical composition of Titan's alien dunes. Physical chemist, Dr. Ralf I. Kaiser, and his colleagues, examined remot
