A woman sits at an exhibit booth for “SciX” with a large black backdrop showing colorful space and Earth images and the website “SciXplorer.org.” In front of the backdrop is a table covered with swag items, water bottles, and flyers, plus a large monitor displaying a webpage. The woman, wearing a blazer and conference badge, sits to the right of the table next to an open laptop, smiling toward the camera in a busy conference setting.

For those who observe, remember that the new commandment given this night is to love one another. #LastSupper ( #MaundyThursday) is associated w/ a #Passover seder observed by Jesus hence the " #fullmoon after #vernalequinox" part of dating #Easter Sunday #calendar #timekeeping #astrophysics 🍎

thirteen bearded men in robes sit and lean around a white‑clothed table in a dim interior. The central figure stands slightly behind the table, raising one hand as he speaks, while the others react with animated gestures and varied expressions, some turning toward him, some arguing among themselves. Plates of bread, a fish, cups of wine, and glass flasks are scattered on the table, with bare feet and legs visible beneath. At the bottom of the scene sit a brass basin, a metal flask, and a small dog curled on the floor near the right corner.

An open medieval Hebrew manuscript with two facing pages of large black calligraphic text on aged, yellowed parchment, lightly stained and worn. Along the bottom margin runs a colorful illustrated scene: on the left page, a figure in a pointed hat bakes round flatbreads in a brick oven while another figure carries a tray of three yellow round loaves. On the right page, several similarly dressed figures in pointed hats and robes stand behind or push carts piled with the same round loaves, one holding up a cup as if making a blessing.

This captivating image showcases the journey of the Sun through the sky during the winter solstice (bottom), equinox (middle), and summer solstice (top) in Bursa, Turkey, between 21 December 2007 and 20 June 2008. Using a fisheye lens, the photographer captured the Sun's positions at regular intervals from sunrise to sunset on three different days, illustrating the changing lengths of day and night throughout the year. The variations in the Sun’s daily path across the sky, its height at midday, and the positions of sunrise and sunset, as well as the length of a day, depend on Earth’s axial tilt relative to its orbit around the Sun. The series was taken from a rooftop in Bursa, where the local terrain adds its own unique touch by occasionally obstructing the horizon. Oriented with north at the top and south at the bottom, this visual diary serves as a stunning representation of the Sun’s path for those residing in mid-northern latitudes.
