Get Better Pluto Rings Results By Following Five Simple Steps

"If you really want to know for sure whether there's any dust there, the viewing geometries where you're looking past the dust with the sun in the background, that's the gold standard," states Matthew Tiscareno of the SETI Institute in Mountain View, Calif., who researched Saturn's rings with all the Cassini space craft but wasn't engaged in New Horizons. That is somewhat surprising, Lauer states. Nevertheless, the chaotic gravity of Pluto's group of moons could make it too tricky for rings to discover orbits.

Or even the slight pressure generated by particles streaming out of sunlight could constantly blow shark particles off. And some studies suggest that Pluto probably had rings at one point in its past, left over from the collision that formed its largest moon, Charon. Pluto does not have any bands -- New Horizons triple-checked. An exhaustive search for dust and rings particles across the dwarf planet prior to, during and following the spacecraft flew past Pluto in 2015 has come up vacant.

New Horizons noticed craters over Pluto and Charon than expected, that might mean there are less smaller bodies in the space out of sunlight turning in to Pluto and its moons and wrapped dust up. The group declared that the spacecraft's trajectory secure, and New Horizons flew drifted firmly past Pluto on July 14, 2015 (SN Online: 7/15/15). Subsequent to the flyby, the team flipped New Horizons around to look back in Pluto, also towards the sun.

This has been a much better position when emptied from the sun like motes of dust to start looking for rings, so as dirt particles would burst into view. Before New Horizons arrived at Pluto, the possible existence of rings was an urgent matter of safety. Hitting a particle as small as a sand grain could have damaged the spacecraft. This can be good information for New Horizons' next act. After five months in hibernation, the spacecraft woke up on September 11 and has set its sights on a smaller, weirder and more distant object: a space rock about 30 kilometers long called 2014 MU69 (SN Online: 7/20/17).

Initial observations suggest it might be a double object, with two bodies orbiting closely or touching lightly. "It's a very long paper to say we didn't find anything," says team associate Tod Lauer of this analysis, posted online September 23 in arXiv.org. But the nonresult could help scientists know that the contents of their outer solar program -- and also help plan New Horizons' next encounter. Nine weeks before New Horizons' closest approach to Pluto, a team jokingly referred to as the "crow's nest" acted substantially like a ship's lookout for possible threats, states Lauer, an astronomer using the National Optical Astronomy Observatory in Tucson, Ariz.
