    Blog 65: Comets, Part 1
    Earthlings should be treated to a beautiful holiday surprise in December, Comet Wirtanen 46P. Dr. P. Clay Sherrod, the researcher, educator and author whose Arkansas Sky Observatories are renowned as "America's oldest private research science and observatory facility," wrote, "As this comet is slowly closing in on perihelion this December 16 (closest pass by the sun) it will also swing closely by Earth four days later in December and it perhaps might be as bright as 3rd magnitude, or even a bit

    Blog 64: Nature's laws
    During my years as a newspaper science reporter, I sometimes asked astronomers and physicists a question that still puzzles me: natural laws govern everything from radiation released by atomic bombs to the combinations of molecules, from galaxy shapes to ripples in a pond -- were these rules present at the time of the Big Bang, before a single atom had formed?

    Blog 62: Astronomy in the time of fire
    Utah is suffering the worst summer in many years, in terms of conditions for astronomy. Wildfires that are exacerbated or caused by global warming have been burning up the West, including this state, contributing to a sometimes-dangerously smoky atmosphere. Smoke will soften astronomy images into blurred messes and throw off color balance. When I found sites where the smoke had cleared, by an unfortunate coincidence windy skies made the stars twinkle and bounced my telescope around too wildly
