Today is the Hubble Space Telescope's birthday — it's been exactly 24 years since it was launched into orbit. The optical telescope captures drop-dead gorgeous images of space, and is a constant source of both new science and new computer wallpapers.

The Hubble Space Telescope was launched on April 24th, 1990. It was released in orbit the following day.

The first photos back from Hubble were underwhelming. A crucial flaw in the main mirror was producing fuzzy images, breaking the hearts of astronomers everywhere.

After ground-based modelling and testing, corrective optics were developed to compensate for the mirror. The first service mission to the Hubble installed these optics — yes, that means the Hubble Space Telescope wears glasses. After that, it was beautiful picture after beautiful picture, in a stream of breathtaking astronomy.

Later servicing missions added additional instruments, and replaced gyroscopes and batteries. A final servicing mission was almost cancelled after the Columbia disaster, but was rescheduled after public pressure to repair the beloved telescope.
