For as long as humans have walked the Earth, the great endless sky and the countless stars that fill it have left us in a state of awe-inspired wonderment. Similarly, the study and exploration of space have been a priority for humankind for millennia. From the ancient Assyrians and Greeks, to the greatest minds of the Renaissance, and up to the billionaire space explorers of the 21st century, incredible amounts of time and effort have gone into better understanding our celestial surroundings. And yet, despite all of the great strides that have been made to understand the great beyond, it's estimated that 95% of the universe is still undiscovered.
Thanks to NASA's newly unveiled James Webb Space Telescope, mankind can now discover a little more. The monumental telescope (which cost US$10 billion) has been in development for decades and is the size of a tennis court. On July 12, it was deemed ready for scientific exploration, and the first images were shared with the world. The telescope has been tuned to see the sky in infrared which means we'll be able to see more than ever before. In fact, it can observe cosmic events that occurred much further back in time, 13.5 billion years to be exact!
The initial images have captured never-before-seen nebulae and clusters of galaxies that are millions of light-years away. Click through the gallery to see more, and learn about some of the other greatest discoveries of astronomy and our universe.
