BOULDER, Colo. (KDVR) – A team of some 1,000 undergraduate students at the University of Colorado Boulder were recruited by a team of physicists to help solve a mystery about the sun.The question has long puzzled even veteran astrophysicists: How can the surface of the sun be cooler than its outermost atmosphere?Students at CU Boulder contributed an estimated 56,000 hours researching, and what they found challenged a popular astrophysics theory.The contradicting theoryTelescopic evidence suggests the outermost atmosphere, or corona, burns at temperatures in the millions of degrees Fahrenheit. Yet, the surface of the sun is much cooler at only thousands of degrees, according to CU Boulder.“That’s like standing right in front of a campfire, and as you back away, it gets a lot hotter,” said James Mason, the lead author of the study and an astrophysicist at the Johns Hopkins University Applied Physics Laboratory.

COVID-19 public health emergency in Massachusetts to end on Thursday

Published Tue, 04 Mar 2025 12:55:56 GMT

The COVID-19 public health emergency in Massachusetts will end on Thursday, the same day the federal government’s emergency order is set to expire. The end of the public health emergency will mean individuals will no longer have to wear a mask in hospitals or other health care settings.While the emergency is ending, officials from the state Department of Public Health have said it is still important for people to understand how to protect themselves from COVID-19 in the future. “People should continue to look around their communities and understand how they can protect themselves in the ways that they may want to layer in prevention strategies like masks and testing,” said DPH Commissioner Robert Goldstein. Gov. Maura Healey announced in March that she would lift the state’s modified public health emergency on May 11 to match the day the federal emergency ends. Massachusetts has been operating under the public health emergency status since 2021, when a previous ...

Buck Showalter gets ejected for the 1st time as Mets manager during team’s 7-6 loss to Reds

Published Tue, 04 Mar 2025 12:55:56 GMT

The Mets continued their dreadful play with a 7-6 loss against the Cincinnati Reds on Tuesday night. The team got another short start from David Peterson. But batters came alive later in the game in attempt to spark a late rally.To make matters worse, manager Buck Showalter got ejected from the game in the fifth inning with his team losing, 4-1, which served as a microcosm of frustration during the early struggles for his club this season.Before the Reds extended the lead to 7-1, Showalter was tossed after arguing that Reds outfielder Will Myers interfered with a live ball in the infield. Reds shortstop Kevin Newman hit the ball up the middle near second base, as Myers slid with his right arm extended into the direction of Francisco Lindor. Myers’ arm obstructed the star shortstop from making a clean play, justifying Showalter’s frustration.Showalter voiced his displeasure with the umpires in an angry rant, leading to his first ejection as the Mets skipper. Myers’ ...

Grayson Rodriguez, Adley Rutschman bounce back in Orioles’ 4-2 win over MLB-best Rays

Published Tue, 04 Mar 2025 12:55:56 GMT

Grayson Rodriguez learned a valuable lesson after his start last week.Pitching against the lowly Kansas City Royals, Rodriguez had the worst outing of his nascent big league career, as a lineup with few recognizable major leaguers tagged the top prospect for eight hits and six runs in 3 2/3 innings.“Really it doesn’t matter who you face, what their record is,” Rodriguez said. “They’re all big league hitters.”Rodriguez didn’t have those same issues Tuesday.Substitute the Royals for the MLB-best Tampa Bay Rays and the ineffective version of Rodriguez for a resolute version, as the right-hander battled through a career-high 5 2/3 solid innings to lead the Orioles to a 4-2 win over their division foe.Rodriguez (2-0) wasn’t as dominant as he was in Detroit in late April or throughout his minor league career, but he also didn’t unravel in any inning as he did in most of his previous starts this season. The 23-year-old scattered seven h...

Column: Willson Contreras has a lot to learn about being a true villain at Wrigley Field

Published Tue, 04 Mar 2025 12:55:56 GMT

It’s not hard to become a villain at Wrigley Field, especially when you’re wearing a St. Louis Cardinals uniform.The formula is pretty simple.Be a star player. Have some big moments against the Cubs in Chicago. Rub it in their faces. Bonus points if you’ve ever been suspected of cheating.Former Cubs catcher Willson Contreras happily accepted the challenge this week in his return to his old home, waving his arms in the air after getting on base Monday to coax Cubs fans into booing him louder.It was entertaining to watch, unless perhaps you were the Cubs manager.“Every team has a different celebration — that could be to his teammates,” a grumpy David Ross said after the game. “I don’t know who that’s for, so that’d be stupid to comment on.”Baseball is entertainment, so kudos to Contreras for playing along and trying to breathe some life into a rivalry that has seen better days. Since Ryan Braun retired from the Milwauke...

Elvis Andrus came up with two on and one out in the fifth inning Friday against the Cincinnati Reds. The Chicago White Sox trailed by three runs at Great American Ball Park.That changed with one swing as Andrus homered to left on a 2-2 pitch to tie the game.Not only was it Andrus’ first home run of the season, it was also his first time getting to wear the team’s home run jacket that he was instrumental in bringing to the Sox dugout.“It was awesome,” Andrus told the Tribune on Saturday of slipping on the jacket. “It was my idea. I was one of the few guys without a homer. I was like, ‘OK, I like putting it on (a teammate), but I want to put it on myself too.’“Very happy I was able to get the feeling with the jacket on.”Team home run celebrations are all the rage. The Toronto Blue Jays had a jacket, which reportedly was retired recently. The Minnesota Twins have a version that serves as a nod to fishing.Teammates are liking the Sox...
