The Cosmic Microwave Background (CMB) is the afterglow of the Big Bang, providing a snapshot of the universe when it was just 380,000 years old. Captured by the COBE satellite in 1992 and later refined by the WMAP and Planck missions, the CMB image is a map of the universe's earliest light. This image has been instrumental in confirming the Big Bang theory and understanding the universe's age, composition, and development. The CMB's uniformity and slight fluctuations offer clues about the universe's initial conditions and the formation of large-scale structures.

6. The Black Hole in M87: Visualizing the Invisible

In 2019, the Event Horizon Telescope (EHT) collaboration unveiled the first-ever image of a black hole, located in the center of the galaxy M87. This groundbreaking image shows a glowing ring of hot gas orbiting the black hole's event horizon, providing direct evidence of these enigmatic objects' existence. The image confirmed predictions of Einstein's General Theory of Relativity and opened new avenues for studying black holes and their role in galaxy formation. It also demonstrated the power of global scientific collaboration, as the EHT network spanned multiple continents.

7. Saturn's Rings: The Cassini Legacy
