Never Changing Pluto Rings Will Eventually Destroy You

It required the greater portion of a calendar year for several of the information from New Horizons to return to Earth, and several months after that to test it, however, the group is currently ready to get in touch with it: The rings really are not there -- or even at least they're overly buoyant to see. "It's a very long paper to say we didn't find anything," says crew member Tod Lauer of this study, published on line September 2-3 in arXiv.org. But the nonresult can help scientists know that the contents of the outside solar method -- and help plan New Horizons' next encounter.

The spacecraft is now on a course to a space rock in the Kuiper Belt, another 1.5 billion kilometers past Pluto.

The staff declared the space craft's trajectory secure, and New Horizons flew drifted firmly beyond Pluto on July 14, 2015 (SN Online: 7/15/15). The team switched New Horizons around to look back in Pluto, also outside the sun. This really was a much superior place to look for rings, as dust particles could pop into perspective once backlit by sunlight like motes of dust from sunlight by the window.

Nine weeks before New Horizons' closest approach to Pluto, a-team jokingly known as the "crow's nest" acted much enjoy a ship's search for potential hazards, says Lauer, an astronomer with the National Optical Astronomy Observatory in Tucson, Ariz.. The group examined pictures shot with all the space craft's Long Range Reconnaissance Imager digital camera, searching for ring particles reflecting stains or sunlight that transferred against a backdrop to the second from 1 set of images.

Nothing turned up. Additionally, it is possible there just wasn't that much dust there to start out with. New Horizons found craters over Pluto and Charon than anticipated, which could mean that there are little bodies in that space out of sunlight turning into Pluto and its moons and kicking up dust. Pluto doesn't have rings -- New Horizons triple-checked. A thorough search for dust particles and rings across the dwarf planet prior to, during and following that the space craft flew past Pluto in 2015 has come up empty.

"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 this SETI Institute in Mountain View, Calif., who analyzed Saturn's rings with the Cassini space craft but was not involved in New Horizons. Searches with the Hubble Space Telescope in 2011 and 2012 turned up two previously unknown moonsorbiting Pluto -- Kerberos and Styx (SN: 11/28/15, p.

14) -- and zero rings. Even so, many researchers expected to encounter rings, or at least some debris. The four outer planets in the solar system have rings, as do other small bodies in the solar system, like the tiny planetoid 10199 Chariklo (SN: 5/3/14, p. 10). 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.
