RAIN & ROSES

"The brain is a complex system, but that doesn’t mean it’s incomprehensible. Our neural circuits were carved by natural selection to solve problems that our ancestors faced during our species’ evolutionary history. Your brain has been molded by evolutionary pressures just as your spleen and eyes have been. And so has your consciousness. Consciousness developed because it was advantageous, but advantageous only in limited amounts."

Chandra X-ray Observatory Celebrates 15th Anniversary

To celebrate, the Chandra team released four newly processed images of supernova remnants.

TYCHO
More than four centuries after Danish astronomer Tycho Brahe first observed the supernova that bears his name, the supernova remnant it created is now a bright source of X-rays. The supersonic expansion of the exploded star produced a shock wave moving outward into the surrounding interstellar gas, and another, reverse shock wave moving back into the expanding stellar debris. This Chandra image of Tycho reveals the dynamics of the explosion in exquisite detail. The outer shock has produced a rapidly moving shell of extremely high-energy electrons (blue), and the reverse shock has heated the expanding debris to millions of degrees (red and green). There is evidence from the Chandra data that these shock waves may be responsible for some of the cosmic rays - ultra-energetic particles - that pervade the Galaxy and constantly bombard the Earth.

THE CRAB NEBULA
In 1054 AD, Chinese astronomers and others around the world noticed a new bright object in the sky. This “new star” was, in fact, the supernova explosion that created what is now called the Crab Nebula. At the center of the Crab Nebula is an extremely dense, rapidly rotating neutron star left behind by the explosion. The neutron star, also known as a pulsar, is spewing out a blizzard of high-energy particles, producing the expanding X-ray nebula seen by Chandra. In this new image, lower-energy X-rays from Chandra are red, medium energy X-rays are green, and the highest-energy X-rays are blue.

3C58
3C58 is the remnant of a supernova observed in the year 1181 AD by Chinese and Japanese astronomers. This new Chandra image shows the center of 3C58, which contains a rapidly spinning neutron star surrounded by a thick ring, or torus, of X-ray emission. The pulsar also has produced jets of X-rays blasting away from it to both the left and right, and extending trillions of miles. These jets are responsible for creating the elaborate web of loops and swirls revealed in the X-ray data. These features, similar to those found in the Crab, are evidence that 3C58 and others like it are capable of generating both swarms of high-energy particles and powerful magnetic fields. In this image, low, medium, and high-energy X-rays detected by Chandra are red, green, and blue respectively.

G292.0+1.8:
At a distance of about 20,000 light years, G292.0+1.8 is one of only three supernova remnants in the Milky Way known to contain large amounts of oxygen. These oxygen-rich supernovas are of great interest to astronomers because they are one of the primary sources of the heavy elements (that is, everything other than hydrogen and helium) necessary to form planets and people. The X-ray image from Chandra shows a rapidly expanding, intricately structured, debris field that contains, along with oxygen (yellow and orange), other elements such as magnesium (green) and silicon and sulfur (blue) that were forged in the star before it exploded.

Things that Will Make You Feel Old - MOP UP #2 by the1janitor

Just a fun video for you guys this time ^_^

I thoroughly enjoyed this. The one thing that made gasp was Eminem’s age. Holy shit, didn’t he was more than 30.

edwardspoonhands:

The whole SciShow office is so freaking stoked about this it’s adorable. To be clear, I also have not been this excited about a movie (that wasn’t based on my brother’s book) since Deathly Hallows.

Something for us to watch.

Meet Biddy, The Travelling Hedgehog

Those of us who want to travel but do not have the time or the money finally have a solution – we can travel in spirit together with Biddy the hedgehog, a little guy on Instagram whose travel photos are becoming insanely popular.

Toni DeWeese and Tom Unterseher, Biddy’s two loving owners in Oregon, take him on adventures almost every week throughout the Pacific Northwest. He visits mountains, forests, waterfalls, and the occasional donut shop.

"Show me Atheists doing this." Ok, here you go.



Between 1966 and 1976, The People’s Republic of China launched their “Cultural Revolution” which sought to demolish “old” ways of thinking to make way for the new Maoist Communist thought. Temples were defaced, ancient scrolls and statues burned, all by atheists under the banner of Maoist Communism.

People who confuse communism with being an atheist.

Wrong answer coeus-corporation.  Try understanding the Cult of Personality which all religions start out as.  Mao was just another form of god, like yahweh, jesus, allah, mohammed, zeus, jehovah…….
