The Hubble Space Telescope, which turned 25 on Friday, doesn't travel through space. It's in a fairly low orbit -- 353 miles high, just around 100 miles higher than the space station -- and never leaves Earth's side. But over the past quarter of a century, its increasingly impressive resolution has brought us to strange new places.

The Open University is celebrating the Hubble's birthday with a set of adorable, retro-style travel postcards. Humankind may not have physically made it to the beautiful celestial getaways shown, but thanks to the Hubble and the scientists who use it, we've seen them clearly and learned lots about them.

In a few million years, scientists estimate that the Red Rectangle nebula will actually bloom into a shell of diffuse gas, known as a planetary nebula. (Open University)

Sometimes we even get to enjoy a 3-D birds-eye view:

The Sombrero galaxy is one of the biggest objects in its cluster, equivalent to 800 billion suns. (Open University)

The online postcards aren't for sale, unfortunately, but the puns are pretty delightful:

The entire Cone Nebula (made of gas and dust) is seven light-years long. (Open University)

The globular cluster of stars known as Messier54 was discovered by astronomer Charles Messier way back in 1778. (Open University)
