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 Dow fell more than 800 points Wednesday after the bond market, for the first time in over a decade, flashed a warning signal that has an eerily accurate track record for predicting recessions.Here's what happened: The 10-year Treasury bond yield fell below 1.6% Wednesday morning, dropping just below the yield of the 2-year Treasury bond. It marked the first time since 2007 that 10-year bond yields fell below 2-year yields.US stocks fell as investors sold stock in companies and moved it into bonds. The Dow was about 2.8% lower. The broader S&P 500 was also down 2.8% and the Nasdaq sank 3.1% Wednesday.CNN Business' Fear and Greed Index signaled investors were fearful. The VIX volatility index spiked 26%.Investors are on edge because the German economy shrank in the second quarter, and the US-China trade war still looms large over markets despite the latest truce. Industrial production in China grew at the weakest rate in 17 years in July.As the global economy sputters, investors are plowing money into long-term US bonds. The 30-year Treasury yield fell to 2.05%, the lowest rate on record.Government bonds — particularly US Treasuries — are classic "safe-haven" assets that investors like to hold in their portfolios when they're nervous about the economy. Stocks, by contrast, are riskier assets that tend to be more volatile during economic slowdowns.Gold, another safe-haven asset, rose 1% Wednesday.Here's what this all means: Normally, long-term bonds pay out more than short-term bonds because investors demand to be paid more to tie up their money for a long time. But that key "yield curve" inverted on Wednesday. That means investors are nervous about the near-term prospects for the US economy. Bonds and yields trade in opposite directions, so yields sink when investors buy bonds.Part of the yield curve has been inverted for several months. In March, the yield on the 3-month Treasury bill rose above the rate on the 10-year Treasury note for the first time since 2007. It inverted again on July 24 and has remained negative. But Wednesday marked the first time in over a decade that the "main" yield curve — the 2-year / 10-year ratio — had inverted.That spooked Wall Street, because an inversion of the 2/10 curve has preceded every recession in modern history. That doesn't mean a recession is imminent, however: The Great Recession started nearly two years after the December 2005 yield-curve inversion.William Foster, Moody's lead US analyst, predicts the US economy will avoid a recession in 2019 and in 2020, despite the yield curve inversion's warning sign. He expects growth to slow in the second half this year into 2020.The US economy remains strong: Unemployment is historically low, consumer spending is booming, and the financial system is healthy."Even though we're discouraged by the yield curve's shape right now, we see few signs of danger ahead," said John Lynch, LPL Research chief investment strategist, in a blog post.Stocks have grown volatile lately, with the Dow plunging and rising more than 350 points in each session this week. But the yield curve inversion doesn't mean the stock market is about to collapse. The S&P 500 has rallied 22% on average between the first time a yield curve inverts and the start of a recession, Lynch noted.Following the last yield curve inversion in 2005, stocks rose for 12 straight months. 3400

The House of Representatives is expected to vote on Wednesday to hold Attorney General William Barr and Commerce Secretary Wilbur Ross in criminal contempt over a dispute related to the Trump administration's efforts to add a citizenship question to the 2020 census.The latest escalation in tensions between House Democrats and the administration comes after the House Oversight Committee approved a resolution last month recommending that the House find Barr and Ross in contempt "for refusal to comply with subpoenas" 532
