The moon is slowly shrinking over time, which is causing wrinkles in its crust and moonquakes, according to photos captured by NASA's Lunar Reconnaissance Orbiter.Unlike Earth, the moon doesn't have tectonic plates. Instead, as the moon's interior has cooled over the last several hundred million years, it has caused the surface to wrinkle as it shrinks. Unlike the flexible skin of a grape when it shrinks into a raisin, the moon's brittle crust breaks. This creates stair-step cliffs called thrust faults as part of the crust is pushed up and over another close part of the crust.There are now thousands of cliffs scattered across the moon's surface, averaging a few miles long and tens of yards high. The orbiter has taken photos of more than 3,500 of them since 2009. In 1972, Apollo 17 astronauts Eugene Cernan and Harrison Schmitt had to ascend one of these cliffs, the Lee-Lincoln fault scarp, by zig-zagging the lunar rover over it.Today the moon is 50 meters "skinnier" because of this process. And as it shrinks, the moon actively produces moonquakes along the faults. Researchers re-analyzed seismic data they had from the moon to compare with the images gathered by the orbiter.Data from the seismometers placed on the moon during the Apollo 11, 12, 14, 15 and 16 missions revealed 28 moonquakes recorded between 1969 and 1977. Researchers compared the location of the epicenters for those quakes with the orbiter imagery of the faults. At least eight of the quakes occurred due to activity along the faults. This rules out the possibility of asteroid impacts or rumblings from the moon's interior.This means that the Apollo seismometers recorded the moon shrinking, the researchers said. The study of Apollo seismic data and analysis of more than 12,000 of the orbiter's photos were published Monday in the journal 1841

The dog who played Cheddar on "Brooklyn Nine-Nine" has died. He was 13 years old. "We went to the beach (his favorite place) where he frolicked in the surf and then enjoyed a picnic lunch of In & Out burgers. We relaxed in the sun and just enjoyed each other's company," the dog's owner said on Instagram. Our veterinarian met us there later and Stewart went to sleep peacefully in my arms while listening to the sounds of the ocean."Stewart wasn't the only dog to take on the role, but he played the part the longest, according to TMZ. "My precious boy Stewart crossed the rainbow bridge today," his owner shared on Instagram.Cheddar was pet to Captain Raymond Holt and his husband on the show. 712

The convenience stores of Westeros have done good business in recent weeks.Just two weeks after eagle-eyed viewers spotted a rogue takeaway coffee cup in an episode of "Game of Thrones," the show's highly anticipated finale left fans bemused once again.This time, a plastic water bottle made a cameo appearance. Eight years of fighting for the Iron Throne can leave you a bit parched, after all.The bottle debuted in a tense scene as characters discussed the fate of Westeros.Viewers spotted it tucked behind Samwell Tarly's foot, and the show was in hot water on Twitter just moments later.Some viewers said they spied a second water bottle later in the episode.The latest gaffe creates a new headache for HBO, which handled the coffee cup incident deftly, with a lighthearted statement."The latte that appeared in the episode was a mistake. Daenerys had ordered an herbal tea," the company said.The final season of the worldwide phenomenon has received underwhelming reviews and a frosty reception from many longtime fans, who complain the show has been rushed.For some, this latest modern intrusion only made things worse.More than a million people have 1169

The biggest shopping holiday of the year, Black Friday, is mere weeks away, and many retailers are gearing up for a shortened holiday shopping season.Because Thanksgiving will be on the latest possible day, Nov. 28, there will only be 26 shopping days between Thanksgiving and Christmas. There were 32 such days in 2018. Because of the compressed holiday shopping season, this could be a busier-than-usual Black Friday.Although many large retailers are now expected to be open on Thanksgiving evening, in recent years, the trend of stores opening even earlier on Thanksgiving has subsided. That means customers should be able to have time to eat some turkey before getting in line to score big deals.At some retailers, customers were able to shop all night after Thanksgiving and into the morning on Black Friday at some retailers. Old Navy and Kohl's are among a handful of retailers that will remain open all night. Target, Sears and Best Buy are among a number of retailers that will close for a few hours and reopen early on Black Friday. 1055
