In April 2017, scientists used a global network of telescopes to see and capture the first-ever picture of a black hole, according to an announcement by researchers at the National Science Foundation Wednesday morning. They captured an image of the black hole at the center of a galaxy known as M87."We have seen what we thought was unseeable," said Sheperd Doeleman, director of the Event Horizon Telescope Collaboration. "We have seen and taken a picture of a black hole."The Event Horizon Telescope Collaboration, called EHT, is a global network of telescopes that captured the first-ever photograph of a black hole.In their attempt to capture an image of a black hole, scientists combined the power of eight radio telescopes around the world using Very-Long-Baseline-Interferometry, according to the European Southern Observatory, which is part of the EHT. This effectively creates a virtual telescope around the same size as the Earth itself.What is a black hole?Black holes are made up of huge amounts of matter squeezed into a small area, according to 1071

It sounds like a scene from a monster movie.Children from a church group were playing in a creek in West Alexandria, Ohio, on Wednesday evening when one of their leaders spotted a 7-foot-long crocodile swimming nearby.There were 16 kids -- all first- through sixth-graders -- playing in Bantas Fork Creek, and adults were in the water and on a small bridge to keep an eye on them, according to Rick Turnbull, who helps teach the children.Another adult "saw something in the water, a shadowy object moving, and he yelled down to the person on that side of the bridge and shouted 'get the kids out of the water,' " Turnbull said.Rich Denius was in the water with one of his sons and helped get the children to safety."Give Jesus all the glory for protecting these kids," Denius said.The crocodile was about 20 feet away by the time everyone got out of the creek. Turnbull said it swam right under the bridge they were standing on."He wasn't afraid of us. He swam under it, popped his head up and looked at us," he said.A wildlife officer was called in and shot the animal. Turnbull said the kids had been taken out of the area before that happened.It was probably a petCrocodiles are not native to Ohio, and the state's veterinarian said it was probably a pet that someone dumped when it got too big."This was the first sighting, so he probably hadn't been in there very long," Dr. Tony Forshey said.The crocodile was 7? feet long and weighed 171 pounds, he said.Forshey said officials scanned the animal for a microchip ID but didn't find one, and there weren't any signs of other crocodiles in the area.It's an unforgettable lessonTurnbull said the church group takes the children down to the creek a couple of times each summer, when the water's warm, to study nature as part of their religious lessons.On Wednesday, they discussed how some fish will gather together near a light source to protect themselves from predators."It was wild that we'd had a lesson about predators lurking in the shadows," he said.West Alexandria is about 20 miles west of Dayton, so they also talked about the need to be aware of their surroundings -- especially after last week's shooting in a popular Dayton nightlife district.Turnbull also stressed the importance of obeying people in authority, which really paid off because when the time came, the children climbed out of the creek without complaint."It's a lesson that these kids will never forget," he said. 2456

ocally because she says we don't know enough about health effects. Some studies claim 5G transmissions can contribute to a variety of health problems, and a number of cities are attempting to stop the towers and slow the rollout."As a registered nurse, I am very much about informed consent," Krinsky said, "which is the right to choose, the right to decline." But she says community residents were never given an option when it came to the towers.How do you know if 5G is coming?Here's telltale sign your community is about get 5G towers: You'll see white PVC tubes, typically with an orange cap, popping out of the ground. These pipes contain fiber lines that then connect all the 5G towers as they have to be connected with fiber line to reach their promised high speeds.The 5G towers that follow are much smaller than typical cell towers.Verizon corporate spokesman David Weissmann confirms that the small black tubular towers are new, small cellular Verizon towers, installed to "ease network congestion" and help with video streaming in areas with weaker service. He says they currently broadcast 4G LTE but can be converted to 5G in the future, whenever 5G service arrives. The Federal Communications Commission and Federal Aviation Administration say there are no proven links between 5G cell service and health effects and local residents have no reason to fear these new towers.As always, don't waste your money.__________________________Don't Waste Your Money" is a registered trademark of Scripps Media, Inc.

It's Opening Day for Major League Baseball! That means it’s time for warmer weather, baseball and…long lines at the ball park.But to shorten waiting times, stadiums around the country are using CLEAR, the biometric screening you see at the airports. At the Colorado Rockies Coors Field, fans typically wait on average about 15 to 20 minutes before getting into the stadium. With the new addition of CLEAR, the wait time is cut down to about 5 minutes. “They can really come to the ball park whenever and experience that expedited entry,” explains Walker Monfort with the Colorado Rockies. The team partnered with CLEAR to give fans the opportunity to get priority into the ballpark. Signing up for CLEAR at a stadium is free, but you can only use your membership at that stadium. But if you sign up for the 9/year membership at an airport, it will give you a priority at both locations. “You use your fingerprints, just like you would at the airport. You get into the ballpark,” says Ed O’Brien, head of sports at CLEAR, of the process. “We will then check your ticket. Then, you will go through the screening process, whether with a metal detector or with a wand.” More than a dozen stadiums across the country are using CLEAR. O'Brien says Clear is planning to expand the number of stadiums and how the technology is used. In Seattle, Seahawks and Mariners fans can link their driver’s license and credit card to their CLEAR account to grab a beer at the concession stand with their finger print. CLEAR is working to one day allow fans to use their fingertip as a ticket. 1593

Just hours after a heated interview aired on CBS where musician R. Kelly declared his innocence on charges of sexual abuse, he was back in custody on Wednesday for failing to pay child support. According to the Chicago Tribune, Kelly has failed to pay more than 1,000 in back child support. A Cook County, Illinois judge said that Kelly must pay the 1,000 in full in order to be released. He had previously been out on bond after spending four days in jail on charges of sexual abuse. Kelly had a friend help him pay the 10 percent of the million bond he needed in order to get out of jail. Kelly's publicist, Darryll Johnson, told the Chicago Tribune that Kelly had ,000 to ,000 ready to pay on Wednesday, but the judge wanted the full amount. “As you know, he hasn’t worked in a long time,” Johnson told the Tribune. Kelly will next appear in court on March 13. 892
