Get Deep With the Hubble eXtreme Deep Field

The Hubble Space Telescope has had a remarkable impact on space science and humanity. From observations of the outer planets of our solar system to exploring other stars and nebulae in our galaxy, Hubble has been an impressive mission and has produced some of the most incredible images of the cosmos to date. One series of incredible images are the Hubble Deep Field (HDF), the Hubble Ultra-Deep Field (HUDF), and the Hubble eXtreme Deep Field (HXDF).

The picture above shows the HXDF in all of its glory. Released in 2012, this picture shows a smattering of galaxies, something in the range of 5,500 of them, and some of them are as far away as 13.2 billion lightyears (meaning that some of those blobs of colored light in this image sent their shine our way some 13.2 billion years ago!).

Just looking at this image should make one wonder about the immense vastness of our universe and the potential things that may be happening in any of those thousands of galaxies far, far away. Now that have evidence to show that many stars in our galaxy have planets, it makes me wonder about how many worlds are out there in just this one region of space from the HXDF alone. Could there be other inhabited worlds? Are there species of beings out there who are turning their own instruments our way and seeing our light from long ago flashing at them? I'd like to think so.
