Dougal Robertson (1924–1992) was a Scottish author and sailor born in Edinburgh who survived with his family being adrift at sea for 38 days after their 43-foot schooner, the Lucette, was sunk by a pod of killer whales in 1972 while on circumnavigation of the world trip. He recounted the ordeal in his books “Survive the Savage Sea” and "Sea Survival – A Manual" More

Comet McNaught, the Great Comet of 2007, grew a spectacularly long and filamentary tail. The magnificent tail spread across the sky and was visible for several days to Southern Hemisphere observers just after sunset. The amazing ion tail showed its greatest extent on long-duration, wide-angle camera exposures. During some times, just the tail itself was visible just above the horizon for many northern observers as well. Comet C/2006 P1 (McNaught), estimated to have attained a peak brightness of magnitude -5 (minus five), was caught by the comet's discoverer in the featured image just after sunset in January 2007 from Siding Spring Observatory in Australia. Comet McNaught, the brightest comet in decades, then faded as it moved further into southern skies and away from the Sun and Earth. Over the next month, Comet Tsuchinshan–ATLAS, a candidate for the Great Comet of 2024, should display its most spectacular tails visible from the Earth.

While hunting for comets in the skies above 18th century France, astronomer Charles Messier diligently kept a list of the things encountered during his telescopic expeditions that were definitely not comets. This is number 27 on his now famous not-a-comet list. In fact, 21st century astronomers would identify it as a planetary nebula, but it's not a planet either, even though it may appear round and planet-like in a small telescope. Messier 27 (M27) is an excellent example of a gaseous emission nebula created as a sun-like star runs out of nuclear fuel in its core. The nebula forms as the star's outer layers are expelled into space, with a visible glow generated by atoms excited by the dying star's intense but invisible ultraviolet light. Known by the popular name of the Dumbbell Nebula, the beautifully symmetric interstellar gas cloud is over 2.5 light-years across and about 1,200 light-years away in the constellation Vulpecula. This impressive color image highlights details within the well-studied central region and fainter, seldom imaged features in the nebula's outer halo.

Comet C/2023 A3 (Tsuchinshan–ATLAS) is growing brighter in planet Earth's sky. Fondly known as comet A3, this new visitor to the inner Solar System is traveling from the distant Oort cloud. The comet reached perihelion, its closest approach to the Sun, on September 27 and will reach perigee, its closest to our fair planet, on October 12, by then becoming an evening sky apparition. But comet A3 was an early morning riser on September 30 when this image was made. Its bright coma and already long tail share a pre-dawn skyscape from Praia Grande, Santa Catarina in southern Brazil with the waning crescent Moon just peeking above the eastern horizon. While the behaviour of comets is notoriously unpredictable, Tsuchinshan–ATLAS could become a comet visually rivaling C/2020 F3 (NEOWISE). Comet NEOWISE wowed skygazers in the summer of 2020.

"In the spring of 2022, Gary Bent underwent surgery to remove a bleeding lesion in his brain resulting from melanoma. The procedure left him with severe mobility and cognitive impairments — he couldn’t walk or remember how to read a calendar.
Bent’s physicians said he needed intensive rehabilitation. Luckily, there was a spot available at one of only three facilities in the state that provide that level of care. Then, Bent’s Medicare Advantage plan denied the prior authorization." More at The Connecticut Mirror ➜

"In September, the U.S. Geological Survey Cascades Volcano Observatory (CVO) and Pacific Northwest Seismic Network (PNSN) located six earthquakes at Mount Adams, ranging from magnitudes 0.9 to 2.0. Typically, earthquakes at this volcano are located at a rate of about 1 earthquake every 2-3 years. With just one seismic station near the volcano, monitoring capabilities are currently limited. CVO and PNSN plan to install temporary seismic stations in the Mount Adams area, which will allow detection of smaller earthquakes and better estimates of size, location, and depth, information necessary to assess the significance of the activity. Currently, there is no indication that the level of earthquake activity is cause for concern, and the alert level and color code for Mount Adams remain at GREEN / NORMAL. CVO and the PNSN will continue to monitor earthquake activity and release further updates as the situation warrants". More

The second solar eclipse of 2024 began in the Pacific. On October 2nd the Moon's shadow swept from west to east, with an annular eclipse visible along a narrow antumbral shadow path tracking mostly over ocean, crossing land near the southern tip of South America, and ending in the southern Atlantic. The dramatic total annular eclipse phase is known to some as a ring of fire. Still, a partial eclipse of the Sun was experienced over a wide region. Captured at one of its earliest moments, October's eclipsed Sun is seen just above the clouds near sunrise in this snapshot. The partially eclipsed solar disk is close to the maximum eclipse as seen from Mauna Kea Observatory Visitor Center, Island of Hawaii, planet Earth.
