 On May 20th in the world of astronomy, one of the most exciting events occurred back in 1990: the Hubble Space Telescope transmitted its first image from orbit!

Picture this: after years of anticipation, delays, and a nail-biting launch aboard the Space Shuttle Discovery on April 24, 1990, astronomers around the world were holding their breath. Would this ambitious $1.5 billion project actually work? Would we finally have our unobstructed window to the universe?

As the clock ticked past midnight and May 20th dawned, the Hubble team at NASA's Goddard Space Flight Center in Greenbelt, Maryland, was abuzz with excitement. The moment of truth had arrived. With a series of commands sent to the orbiting telescope, Hubble's aperture door opened, allowing starlight to flood its main mirror for the first time in space.

The target? A humble cluster of stars in the constellation Carina, about 1,260 light-years away. Nothing too flashy, but perfect for testing the telescope's capabilities.

As the data began streaming down to Earth, the team huddled around their monitors, eager to see the results. And then, there it was – Hubble's first image! While it wasn't the crystal-clear view they had hoped for (later discovered to be due to a flaw in the primary mirror), it was still sharper than any ground-based telescope could achieve.

This moment marked the beginning of a new era in astronomy. Despite its initial setbacks, Hubble would go on to revolutionize our understanding of the cosmos, capturing breathtaking images of distant galaxies, nebulae, and even helping to determine the age of the universe.

So, as you go about your day on May 20, 2025, take a moment to look up at the sky and think about Hubble. It's still up there, 35 years after that first image, continuing to unveil the secrets of our vast and beautiful universe. Who knows what wonders it might reveal next?
