SATURN'S RINGS--A natural-color image of Saturn from space, the first in which Saturn, its moons and rings, and Earth, Venus and Mars, all are visible, is seen in this NASA handout taken from the Cassini spacecraft July 19, 2013 and released November 12, 2013. The image captures 404,880 miles (651,591 kilometers) across Saturn and its inner ring system, including all of Saturn's rings out to the E ring, which is Saturn's second outermost ring. Cassini's imaging team processed 141 wide-angle images to create the panorama. REUTERS/NASA/JPL-Caltech/SSI/Handout via Reuters (OUTER SPACE - Tags: SCIENCE TECHNOLOGY TPX IMAGES OF THE DAY)

Seems like we're always hearing about Saturn's moons; their weird features, unexplained mysteries and, of course, their possibility of hosting life.

Now, we could have a new chunk of Saturn rock to speculate about. Scientists think they may have just witnessed a tiny moon being born in the planet's rings.

They noticed a bump toward the outer edge of the rings in a photo snapped by the Cassini probe last year. The working theory is that the bump is a dust cloud clumping around a half-mile wide baby moon. (Via NASA)

The study's lead author said: "We hadn't seen anything like this before. ... We may be looking at the act of birth, where this object is just leaving the rings and heading off to be a moon in its own right." (Via Queen Mary University of London)

The new moon joins at least 60 brothers and sisters orbiting Saturn, all with unique characteristics. Not much is known about the new moon, but it does have a unique nickname: Peggy.

If confirmed, Peggy could help scientists understand how Saturn's moons form, which in turn could help them understand how the planets formed back at the dawn of the solar system. It's thought the two processes are similar. (Via European Space Agency)

But here comes the splash of cold water on the story: Slate's astronomer Phil Plait points out later pictures of that area of the ring show the tiny moon may have crumbled apart already. And at any rate, Saturn's rings are pretty much done making moons at this point. There's just not enough material left.

Another possibility is that the baby moon just drifted out of the Cassini probe's field of vision. We won't know for sure until the probe gets a closer look in 2016.

  • It led to road closures, right around rush hour Thursday afternoon.   The Jacksonville Sheriff's Office is investigating after a triple shooting in the Magnolia Gardens neighborhood in Northwest Jacksonville.   Police say they were called about multiple people shot at the intersection of New Kings Road and Edgewood Avenue and when they arrived they found three victims with what appeared to be non-life threatening injuries.   According to JSO, it's believed the suspect(s) pulled up next to the vehicle the victims were in and fired several shots into the car.   At this time, there's no information or description of the suspect(s). 
  • Prior to Monday’s premiere of “Dancing with the Stars” Season 24, former figure skater and “DWTS” champion Kristi Yamaguchi took to Twitter to wish fellow former figure skater Nancy Kerrigan good luck in the worst way possible. >> Read more trending news Hours before Kerrigan took the stage, Yamaguchi tweeted, “So excited for you @NancyAKerrigan ! Can’t wait to see you grace that ballroom floor, break a leg!” Yes, that’s right. She told Kerrigan, victim of the famous 1994 attack, in which she was assaulted with a police-style baton to the knee, to “break a leg.” Just before the U.S. Figure Skating Championships in Detroit that year, a man, who had been paid by Kerrigan rival Tonya Harding’s ex-husband, struck her on the right knee, injuring her leg. While it wasn’t broken, Kerrigan did suffer cuts, bruises and swelling and walked with a limp. Twitter responded with generally surprised reactions. Of course, Yamaguchi was just employing a common -- if ill-fitting, considering Kerrigan’s history -- phrase, but that didn’t stop the internet from freaking out over it. Yamaguchi has not clarified her comment, nor has she deleted the tweet. Kerrigan took the joke in stride, tweeting, “Thank you @kristiyamaguchi for the advise (sic)! It definitely is helping!”
  • For two years, Mitch Comer’s mother and stepfather, Sheila Comer and Paul Comer, kept him locked inside a bedroom in his family’s rental home in Georgia. He was shut off from the outside world and even his two younger sisters until September 2012. By then, Comer, who was 18 at the time, was loaded on a bus and sent to Los Angeles with some cash and pamphlets from a homeless shelter. He was spotted by a former security guard, st the Los Angeles bus station, who called police. When he was returned to Georgia, Comer was severely malnourished with translucent skin — evidence of his ordeal. The story made national headlines. >> Read more trending news Nearly five years after his mother and stepfather were sentenced to 15 years in prison as part of a plea deal, the two could be up for parole, according to the Paulding County District Attorney. In his first public interview since his ordeal, Comer said Thursday he doesn’t want that to happen. “I don’t think that’s right,” he said. “I don’t like it at all.” Mitch Comer, who now goes by Mitt, said Paul and Sheila Comer should serve more prison time, and DA Dick Donovan agrees. “Letting them out after just five years just doesn’t … it offends me as a prosecutor and I’m sure it would offend the people of Paulding County if they knew about it,” Donovan said. Despite the two years of his life that was taken from him, Comer has flourished, completing high school and now studying at Kennesaw State University. His passion is electronics, and one day, he’d like to be inventor. Until then, he’s like any other college student, he says. He’s managed to put his abuse behind him. “A long time ago, I heard about a dude that was left in a closet and he came out happy, and I said I’m going to be that dude, too,” Comer said.
  • An inmate in a Pennsylvania jail the Allegheny County Jail is accused of plotting the murders of five juveniles who accused him of sexual assault. Michael Scherbanic, 29, a prisoner in the Allegheny County Jail and is now charged with 27 new criminal counts, including solicitation to commit criminal homicide.  >> Read more trending news Allegheny County police said they uncovered an elaborate criminal plot to intimidate victims, recruit witnesses to perjure themselves and to try to prevent the trial against Scherbanic on sexual-assault charges.  According to a criminal complaint, Scherbanic told his cellmate he’d pay him as much as $1 million to carry out the plan.   The five targets of the alleged murder plot were five separate victims of sexual assault cases filed against Scherbanic in 2016, police said.  Those cases involve juvenile male students of Scherbanic’s karate dojo, the “Tang Soo Do Karate College' in North Versailles. The complaint said Scherbanic drew diagrams of one of the target’s homes to show his cellmate where a propane tank was that could “be exploded to kill multiple residents.” >> Got a question about the news? See our explainers here  Scherbanic also identified people that his cellmate could recruit to help carry out the plot as well as hide the bodies, the complaint said. There were also plans to destroy the creditability of someone who was going to testify against Scherbanic in the sex-assault trial. Sherbanic told his cellmate to “plant drugs, or a gun or possibly child porn,” the complaint said.  Scherbanic was charged with involuntary deviate sexual intercourse, unlawful contact with a minor, indecent assault, endangering the welfare of children, corruption of minors and indecent assault in those cases. The complaint also alleged Scherbanic had been stashing ground up pain pills in his cell in case the plan did not work, so he could commit suicide.  The investigation was conducted with the assistance of the Jail Administrative Investigators and detectives from the district attorney’s office.
  • More than 100 structures were saved by fire crews in Nassau County, while two homes were destroyed by the wildfire near Bryceville this week. Fire officials maintain this destruction could have been avoided.  “The two (homes) that were destroyed didn’t have any defensible space; they had woods and flammable brush very close to the home,” said Annaleasa Winter, a wildfire mitigation specialist for the Florida Forest Service. “The homes that were saved had a good, clear defensible space where it’s drivable all the way around the structure.” Simply clearing dry brush and wood from around your home, trimming tree limbs and keeping the lawn mowed and irrigated, can alleviate much of the fire risk for your home. By installing metal or fiberglass shingled roofs, you can take additional steps to protect your home structurally from fires.  Winter suggests keeping dry materials and brush, at least, 30 feet from the home. If that’s not possible, because of challenges with space, work out a plan with your neighbor or the business you live next to.  The Florida Forest Service also offers many free services to home owners, like mechanical fuel reduction and the mowing, mulching and chopping of brush around a property.
