Saturn's C and B Rings From the Inside Out On July 1, 2004, NASA's Cassini spacecraft arrived at Saturn, marking the end of the spacecraft's nearly seven-year journey through the solar system as well as the beginning of its tour of Saturn, its rings, moons and magnetosphere.
The NASA/ESA Hubble Space Telescope has captured many breathtaking images of the Universe, but one snapshot stands out from the rest: the Eagle Nebula’s Pillars of Creation. Description from I searched for this on
Oct 2010 Globular Star Cluster NGC 6934 Credit: NASA, ESA, Hubble Space Telescope Globular star clusters roam the halo of r Milky Way Galaxy. Gravitationally bound, these spherical groupings of typically several 100,000 stars r ancient, older than the stars of the galactic disk. In fact, measurements of globular cluster ages constrain the age of the Universe (it must be older than the stars in it!) & accurate cluster distance determinations provide a rung on the astronomical distance ladder.
The Cassini spacecraft captures a rare family photo of three of Saturn's moons that couldn't be more different from each other! As the largest of the three, Tethys (image center) is round and has a variety of terrains across its surface. Meanwhile, Hyperion (to the upper-left of Tethys) is the "wild one" with a chaotic spin and Prometheus (lower-left) is a tiny moon that busies itself sculpting the F ring.
