APOD: 2024 February 29 - Julius Caesar and Leap Days Discover the cosmos!Each day a different image or photograph of our fascinating universe isfeatured, along with a brief explanation written by a professional astronomer. 2024 February 29 Julius Caesar and Leap Days Image Credit &License: Classical Numismatic Group, Inc.,Wikimedia Explanation: In 46 BC Julius Caesar reformed the calendar system.Based on advice by astronomerSosigenes of Alexandria,the Julian calendar included oneleap dayevery four years to account for the fact that an Earthyear is slightly more than 365 days long.In modern terms, the time it takes for the planet to orbit the Sunonce is 365.24219 mean solar days.So if calendar years contained exactly 365 days they would driftfrom the Earth's year by about 1 day every 4 years andeventually July (named forJulius Caesarhimself) would occur during the northern hemisphere winter.By adopting a leap year with an extra day every four years, the Julian calendar year would drift much less.In 1582 Pope Gregory XIII provided the further fine-tuning that leap days should not occur in years ending in 00, unless divisible by 400.This GregorianCalendar system is the one in wide use today.Of course, tidal frictionin the Earth-Moon system slows Earth's rotation and graduallylengthens the day...

Ingenuity's 72nd landing was a rough one though.During descent it lost contact with the Perseverance roverabout 1 meter above the Martian surface.Ingenuity was able to transmit this image after contact wasre-established,showing the shadowof one of itsrotor blades likely damaged during landing.And so, afterwildly exceeding expectationsduring over 1,000 days of exploring Mars,the history-making Ingenuity has ended its flight operations.Nicknamed Ginny, Mars Helicopter Ingenuity becamethe first aircraft to achieve powered, controlled flight on another planeton April 19, 2021.Before launch, a small piece of materialfrom the lower-left wing of theWright Brothers Flyer1, the first aircraft toachieve powered, controlled flight on planet Earth, wasfixed to the undersideof Ingenuity's solar panel.
