In December 1972, Apollo 17 astronauts explored the Moon's Taurus-Littrow valley. They discovered unique orange soil near Shorty Crater, which provided valuable clues about the Moon's volcanic past. These astronauts remain the last people to walk on the lunar surface.
๐ก Finding orange soil on the Moon is like finding a new color in a familiar painting - it changes how we understand the whole picture.
Why it matters: This mission reminds us of a pivotal moment in human history and highlights the incredible discoveries made on the Moon, inspiring future generations to explore and learn about our solar system.
The European Space Agency (ESA) released its weekly collection of stunning space images captured between December 1st and 5th, 2025. These images offer a glimpse into the ongoing work of space exploration and the breathtaking beauty of our universe.

Why it matters: These images remind us of the incredible advancements in space technology and give us a visual connection to the universe beyond Earth. They inspire curiosity and demonstrate the importance of continued scientific exploration.
The Hubble Space Telescope has snapped another picture of interstellar comet 3I/ATLAS, a cosmic wanderer from beyond our solar system. This icy object, currently 286 million km away, is being closely monitored by astronomers to learn more about the building blocks of other star systems.
