A jet flying almost directly overhead joined the already crowded skies in Gemini tonight, including the Moon, Jupiter, and the stars Castor and Pollux. These two frames were taken 28 seconds apart.

Celestial traffic jam in Gemini tonight . . . high overhead! Tonight, the 86% lit Moon is positioned beside Castor and Pollux, the two brightest stars of Gemini. The Moon essentially becomes a third (and very bright) brother. 😁 And bright Jupiter stands nearby. #astronomy

Tonight's Great Rectangle overhead . . . with corners marked by the Moon, Jupiter, Castor and Pollux (stars in Gemini). Two of Jupiter's moons can be seen by zooming in on the lower right "star." Olympus camera; zoom lens set at 53 mm.

I enjoy explaining across my interests: 🪐 Astronomy — what’s in the sky 🇺🇸 Civil War — citizen soldiers & history 🪙 Coins & stamps — history in objects 🚴🏻‍♂️ Cycling — trails & observations • Retired planetarium director • Astrophotographer Accurate, calm explanations across topics.

12 Days of Lincoln Day 12 — Second Inaugural Lincoln’s Second Inaugural Address may be his greatest speech. Delivered in March 1865 as the Civil War neared its end, its famous line “With malice toward none; with charity for all” emphasized reconciliation over triumph. #CivilWarHistory

12 Days of Lincoln Day 11 — The Lincoln Cent In 1909, on the centennial of Lincoln’s birth, the U.S. replaced the Indian Head Cent with the Lincoln Cent — the first circulating coin to feature a real person. 117 years later, its obverse design hasn’t changed. #CivilWarHistory

Today I enjoyed my first bike ride in 4 weeks! It reached a balmy 45 degrees, with traces of snow still clinging to the less traveled streets.

12 Days of Lincoln Day 10 — Places Named Lincoln Only one town named “Lincoln” existed during his lifetime — Lincoln, Illinois. In the 1850s, Abraham Lincoln helped design the town, practiced law there, and helped shape its future. All others were named for him after his death. #CivilWarHistory

12 Days of Lincoln Day 9 — Lincoln’s Height In the 1850s, the average American man stood about 5’ 7”. At 6’ 4”, Lincoln physically towered over his contemporaries — including Stephen Douglas, who stood a full foot shorter. The contrast became part of his legend. #CivilWarHistory
