When students across the US walk out of class for 17 minutes today, many of them will be wearing orange.It's more than just a simple choice in clothing — it's meant to send a powerful message.The color choice dates back to at least 2013 when 15-year-old Hadiya Pendleton was shot and killed in Chicago. Hadiya was an honor student who was killed in a case of mistaken identity -- a week after she performed at one of the events surrounding President Obama's second inauguration.Her parents, Cleopatra Cowley-Pendleton and Nathaniel Pendleton, picked the color orange to honor her and to call for gun reform.Why? It's what hunters wear to protect themselves — from other hunters.This is how their organization, We are Orange, explains it:"Orange is what hunters wear in the woods to protect themselves and others from harm. Orange is a bright, bold color that demands to be seen. Orange expresses our collective hope as a nation — a hope for a future free from gun violence."The group published a video that ends with the quote "So tell me, can you see me now?"Everytown for Gun Safety, a gun-control advocacy nonprofit, learned of the movement and brought it to the national level.The movement and choice of color has not gone without criticism, however. The National Rifle Association called the campaign "pointless" and a "thinly veiled anti-gun stunt" in a statement in its journal, America's 1st Freedom.It's not just students who have been wearing orange since the Parkland shooting. Celebrities at the Oscars this year also wore orange pins. 1565

When a Minnesota teacher learned that her school's custodian was in dire need of a new kidney, she didn't hesitate to step up to the plate.According to the Minneapolis Star Tribune and CNN, teacher Erin Durga and custodian Part Mertens have been co-workers at Kimball Elementary School in Kimball, Minnesota, for nine years.The two were well acquainted — they often exchanged pleasantries in the hall, and Durga's children attended a daycare ran by Merten's wife.Recently, Mertens had been leaving school early three days a week to attend dialysis treatments. Earlier this year, the school organized a "Hats for Pat" fundraiser to help pay for his treatments. But school officials didn't realize how dire Mertens' situation was until his daughter posted a plea for help on Facebook.According to Mertens' daughter, Kayla Matten, none of her fathers' relatives was a match for a kidney transplant."We are now in the process of trying to find someone with an O blood type and someone who is willing to donate their kidney," she wrote, according to CNN.When Durga saw the post, she didn't hesitate. She knew she wanted to donate her kidney to a co-worker in need."Why wouldn't you [do it]?" she told the Star Tribune.In late spring, Durga and Mertens found out they were a match."It brought a few tears to my eyes," Mertens told the Star Tribune. "I'm not much for expressing myself."Despite the COVID-19 pandemic, the two underwent the transplant surgery on July 3. Months later, Mertens is doing well, and the Star Tribune reports that he is no longer "tethered" to dialysis treatments."I can live again," Mertens told the Star Tribune. 1642

When Hurricane Michael barreled through Florida's Mexico Beach, it reduced the beachside town to pile of rubble, mangled structures and splintered houses.These aerial images from NOAA offer a stark look at how there's nothing left in some parts where houses once stood.Most houses in the northern section of Mexico Beach, where the canal and marina start, aren't there anymore.The pier toward the bottom of the image, isn't either.Zooming in closer on the marina, the debris from houses is piled up on the northern shore of the canal.The boat moorings, gone. And the debris field extends into the trees beyond the canal. 628

Will be going to Georgia for a big Trump Rally in support of our two great Republican Senators, David and Kelly. They are fantastic people who love their Country and love their State. We must work hard and be sure they win. #USA— Donald J. Trump (@realDonaldTrump) December 2, 2020 289

What does it look like when galaxies collide? The Hubble Telescope captured a unique sight as two galaxies are in the process of merging.NASA says the galaxy, called NGC 1614, is about 200 million light-years from Earth and is the result of a “galactic merger” which has created a unique appearance. They call it “eccentrically shaped” and “ablaze with activity” in a statement on NASA’s website. It sits in the constellation of Eridanus.The result of the cosmic collision is a flow of interstellar gas from the smaller galaxy into the nucleus of the larger one, “resulting in a burst of star formation that started in the core and has slowly spread outward through the galaxy,” NASA says.Astronomers say NGC 1614 is one of the most luminous objects in the local universe. 780
