Researchers have claimed that the size of Saturn’s outermost ring is much bigger than originally thought. Astrophysicist Douglas Hamilton used infrared images from NASA’s Spitzer Space Telescope to discover the Phoebe ring in 2009.
Phoebe can’t be seen with the naked eye because of its dark color. Researchers used the Wide-field Infrared Survey Explorer NASA telescope to get a good view of Phoebe. Findings of the study have been published in the journal Nature. The scientists were able to see just how big it is.
Phoebe is 200 times as big across as Saturn. This study was also led by Hamilton and helped the researchers know that Phoebe is made up of small particles and grains of dust that are quite far apart. It was also reported tat that the particles are so much apart that an agile spacecraft could probably traverse the ring without hitting any particles.
