 On May 20th in Science History, a significant event took place in 1990. On this day, the Hubble Space Telescope sent its first photographs from space, marking a major milestone in the field of astronomy and our understanding of the universe.

The Hubble Space Telescope, named after the renowned astronomer Edwin Hubble, was launched into orbit by the Space Shuttle Discovery on April 24, 1990. After a few weeks of testing and calibration, the telescope captured its first images on May 20th. The images were of the star cluster NGC 3532, also known as the Football Cluster or the Wishing Well Cluster, located in the constellation Carina.

These initial images were not as clear as expected due to a flaw in the telescope's primary mirror, which caused spherical aberration. Despite this setback, the telescope still provided astronomers with valuable data and insights. The flaw was later corrected in 1993 during a servicing mission by NASA astronauts.

Since its launch, the Hubble Space Telescope has revolutionized our understanding of the cosmos. It has captured breathtaking images of galaxies, nebulae, and planets, and has helped astronomers make groundbreaking discoveries, such as the accelerating expansion of the universe and the existence of supermassive black holes at the centers of most galaxies.

The Hubble Space Telescope's contributions to science have been immense, and its first photographs on May 20, 1990, marked the beginning of a new era in astronomy. The telescope continues to operate today, over three decades later, providing scientists with invaluable data and inspiring the public with its stunning images of the universe.
