Guiding Questions 1. What makes up the universe? 2. How does the size of Earth compare to the size of other objects in the Universe? For all of human history humans have looked up at the night sky in wonder and curiosity. Galileo Galilei was the first person to use the newly invented telescope to observe the night sky 410 years ago, in 1610. In April, 1990, only 30 years ago, NASA launched the Hubble Space Telescope. Our knowledge of the universe was greatly expanded with the data and images that the Hubble Space Telescope sent back to the NASA scientists. The most spectacular image from this telescope is called the eXtreme Deep Field, or XDF, released in 2012. To me, this Hubble image below looks like a field of jewels glittering in the night sky! The "jewels" are really galaxies that are 13 billion light years away from Earth. Hubble eXtreme Deep Field (HXDF) taken in 2012, By NASA; ESA; G. Illingworth, D. Magee, and P.

The scientists Use one object to call eXtreme deep field image or XDF and this object is used to see the universe and the scientist study the universe this way.

Samuel, nice job! I like that you included information in your comment about the image taken by the Hubble Space Telescope.
