christinetheastrophysicist: Hubble Sees the Remains of a Star Gone Supernova These delicate wisps of gas make up an object known as SNR B0519-69.0, or SNR 0519 for short. The thin, blood-red shells are actually the remnants from when an unstable progenitor star exploded violently as a supernova around 600 years ago.

SNR 0519 is located over 150 000 light-years from Earth in the southern constellation of Dorado (The Dolphinfish), a constellation that also contains most of our neighboring galaxy the Large Magellanic Cloud (LMC). Because of this, this region of the sky is full of intriguing and beautiful deep sky objects. The LMC orbits the Milky Way galaxy as a satellite and is the fourth largest in our group of galaxies, the Local Group. SNR 0519 is not alone in the LMC; the NASA/ESA Hubble Space Telescope also came across a similar bauble a few years ago in SNR B0509-67.5, a supernova of the same type as SNR 0519 with a strikingly similar appearance.

School Bus Driver Fired for Facebook Post About Hungry Student

The actual people who work with our children care a lot more about them than the superintendents and city officials too busy firing people and closing schools to even notice them.

Bus driver Johnny Cook believed he was doing the right thing when he took to his personal Facebook page to recount the story of a middle school student who approached him to complain about having to go without lunch because he was 40 cents short on his pre-paid cafeteria account.

“This child is already on reduced lunch and we can’t let him eat. Are you kidding me?” Cook wrote in the post. “I’m certain there was leftover food thrown away today.”

Many agreed with Cook’s position, sharing his words tens thousands of times.

But his message also struck a negative chord with officials at Georgia’s Haralson County Middle School, who promptly let him go after he refused to take down the post and apologize.

 … Meanwhile, Cook says he’s been receiving messages of support from parents all around the country who say the same thing happened to their child.

We cannot feed our children and get angry when this is mentioned.
