On the 24th of April, 1990, Space Shuttle Discovery launched the telescope into orbit.
Hubble

Since then, Hubble has operated for nearly _ years, capturing the most stunning images of distant stars and galaxies.

In order to observe the furthest and dimmest objects in the universe, you need a telescope with an extremely high and the ability to capture as much light as possible.

When observing visible light of about 500nm, Hubble has an angular resolution of about 0.05 arcseconds.
This beats the human eye’s resolution by a factor of

When light travels through the universe, its wavelength is stretched with the expansion of space.
This means that by the time the light arrives at Hubble, the wavelength of the light is longer than when it left the object. This is known as
shifting.

One of the main goals of the Hubble telescope was to find the most distant Galaxy in the known universe.
It achieved this in 2016, when it discovered Galaxy

Galaxy GN-Z11 is located 32 billion light-years away and the light we see from it shows the Galaxy as it was billion years ago.

Since the Shuttle program ended in 2011, we no longer have the ability to maintain Hubble, which is starting to take its toll on the telescope.
Hubble has 6 gyros onboard which it uses to maneuver and point its telescope precisely towards its target.
In the last 5 years, 3 of these gyros have failed.
Even if Hubble continues to function over the next decade, its orbit is constantly decaying, and in the 2030’s Hubble will crash into the _ and burn up.
