Trail of the Returner : Familiar stars of a northern winter’s night shine in this night skyview, taken near Zhangye, Gansu, China and the border with Inner Mongolia. During the early hours of December 17 Orion is near center in the single exposure that captures a fireball streaking across the sky, almost as bright as yellowish Mars shining on the right. Splitting Gemini’s twin bright stars Castor and Pollux near the top of the frame, the fireball’s trail and timing are consistent with the second skipping atmospheric entry of the Chang'e 5 mission’s returner capsule. The returner capsule was successfully recovered after landing in Inner Mongolia, planet Earth with about 2 kilograms of lunar material on board. The lunar sample is thought to contain relatively young material collected near the Mons Rumker region of the Moon’s Oceanus Procellarum. Launched on November 23 UT, China’s Chang'e 5 mission is the first lunar sample return mission since the Soviet Union’s Luna 24 mission in 1976. via NASA
Bruce Ackerson - Spaghetti Night, 2020
“After thirty years of intensive research, we can now answer many of the questions posed earlier. The recycle rate of a human being is around sixteen hours. After sixteen hours of being awake, the brain begins to fail. Humans need more than seven hours of sleep each night to maintain cognitive performance. After ten days of just seven hours of sleep, the brain is as dysfunctional as it would be after going without sleep for twenty-four hours. Three full nights of recovery sleep (i.e., more nights than a weekend) are insufficient to restore performance back to normal levels after a week of short sleeping. Finally, the human mind cannot accurately sense how sleep-deprived it is when sleep-deprived.”

Jupiter s Swimming Storm : A bright storm head with a long turbulent wake swims across Jupiter in these sharp telescopic images of the Solar System’s ruling gas giant. Captured on August 26, 28, and September 1 (left to right) the storm approximately doubles in length during that period. Stretching along the jetstream of the planet’s North Temperate Belt it travels eastward in successive frames, passing the Great Red Spot and whitish Oval BA, famous storms in Jupiter’s southern hemisphere. Galilean moons Callisto and Io are caught in the middle frame. In fact, telescopic skygazers following Jupiter in planet Earth’s night have reported dramatic fast moving storm outbreaks over the past few weeks in Jupiter’s North Temperate Belt. via NASA
