Today marks the first orbit Neptune has made around the Sun since it was discovered September 23, 1846. In other words, one Neptunian year, that lasts approximately 165 Earth years. NASA has commemorated this anniversary by releasing new Hubble images of Neptune taken on June 25-26. You can read more about the picture (seen above) on NASA's Hubble Telescope page. Or you can just enjoy Neptune in its pale blue glory.
