“Thor’s Helmet, or NGC 2359″
NGC 2359 is an emission nebula in the constellation Canis Major.
The 8 planets of the solar system in order from the Sun: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.
And I’m putting Pluto in here too so sftu.

Shockwaves of Star Formation - Galaxy M106
Galaxy M106 has mysterious “invisible” spiral arms that only become visible when you observe its X-rays. While the spiral arms propagate like shockwaves around M106, they create bursts of star formation with heat equivalent to 10 million suns. Astrophysicists believe that there is a supermassive black hole at the center of M106. It is theorized that this supermassive blackhole is jetting out high-energy particles into the galaxy’s shockwaves and causing these high energy emissions.

photos of the geminid and perseid meteor shower by (click pic) jeff dai, jeffrey sullivan, michael menefee, jia hao, kenneth brandon, rick whitacre and andrew curtis.
meteor showers are named after the constellation from which the meteors seems to radiate, meaning that if one were to draw the tracks off all the meteors backwards, they would cross at a point in that constellation.
the perseid meteor shower, which peaks around mid august, occurs when the earth passes through the rubble trail left behind by comet 109p/swift-tuttle. the comet has an orbital period of about 120 years, but its debris is spread out fairly evenly along it orbital path, making the perseids a relatively reliable shower.
worth noting, the term meteoroid is used when the object is passing in space, meteor while plunging through our atmosphere, and meteorite if it survives the fall and lands on our planet without vaporizing.
the glow of the meteor comes from atmospheric friction, which heats them up when about fifty miles above the earth’s surface, and slows them down from an initial velocity of about 24,000 mph to a terminal velocity of only 300 mph.
Seriously what has the world come to
Now do not fucking tell me these people are Muslim and represent Islam. Don’t you fucking dare! These monsters don’t represent anything but pure evil. What kind of ppl would have the heart to burn these innocent souls alive in a cage?These devils don’t fear God in any way. They don’t have the slightest idea of what Islam is and represents! No religion in the world would teach you hate and to kill people. I don’t know what else to say except that my heart just shattered into pieces.
Ya Allah !!

First human head transplant could happen in two years
IT’S heady stuff. The world’s first attempt to transplant a human head will be launched this year at a surgical conference in the US. The move is a call to arms to get interested parties together to work towards the surgery.
The idea was first proposed in 2013 by Sergio Canavero of the Turin Advanced Neuromodulation Group in Italy. He wants to use the surgery to extend the lives of people whose muscles and nerves have degenerated or whose organs are riddled with cancer. Now he claims the major hurdles, such as fusing the spinal cord and preventing the body’s immune system from rejecting the head, are surmountable, and the surgery could be ready as early as 2017.
Canavero plans to announce the project at the annual conference of the American Academy of Neurological and Orthopaedic Surgeons (AANOS) in Annapolis, Maryland, in June. Is society ready for such momentous surgery? And does the science even stand up?
The first successful head transplant, in which one head was replaced by another, was carried out in 1970. A team led by Robert White at Case Western Reserve University School of Medicine in Cleveland, Ohio, transplanted the head of one monkey onto the body of another. They didn’t attempt to join the spinal cords, though, so the monkey couldn’t move its body, but it was able to breathe with artificial assistance. The monkey lived for nine days until its immune system rejected the head. Although few head transplants have been carried out since, many of the surgical procedures involved have progressed. “I think we are now at a point when the technical aspects are all feasible,” says Canavero.
This month, he published a summary of the technique he believes will allow doctors to transplant a head onto a new body (Surgical Neurology International, doi.org/2c7). It involves cooling the recipient’s head and the donor body to extend the time their cells can survive without oxygen. The tissue around the neck is dissected and the major blood vessels are linked using tiny tubes, before the spinal cords of each person are cut. Cleanly severing the cords is key, says Canavero.
The recipient’s head is then moved onto the donor body and the two ends of the spinal cord – which resemble two densely packed bundles of spaghetti – are fused together. To achieve this, Canavero intends to flush the area with a chemical called polyethylene glycol, and follow up with several hours of injections of the same stuff. Just like hot water makes dry spaghetti stick together, polyethylene glycol encourages the fat in cell membranes to mesh.
Next, the muscles and blood supply would be sutured and the recipient kept in a coma for three or four weeks to prevent movement. Implanted electrodes would provide regular electrical stimulation to the spinal cord, because research suggests this can strengthen new nerve connections.
When the recipient wakes up, Canavero predicts they would be able to move and feel their face and would speak with the same voice. He says that physiotherapy would enable the person to walk within a year. Several people have already volunteered to get a new body, he says.
The trickiest part will be getting the spinal cords to fuse. Polyethylene glycol has been shown to prompt the growth of spinal cord nerves in animals, and Canavero intends to use brain-dead organ donors to test the technique. However, others are sceptical that this would be enough. “There is no evidence that the connectivity of cord and brain would lead to useful sentient or motor function following head transplantation,” says Richard Borgens, director of the Center for Paralysis Research at Purdue University in West Lafayette, Indiana.
If polyethylene glycol doesn’t work, there are other options Canavero could try. Injecting stem cells or olfactory ensheathing cells – self-regenerating cells that connect the lining of the nose to the brain – into the spinal cord, or creating a bridge over the spinal gap using stomach membranes have shown promise in helping people walk again after spinal injury. Although unproven, Canavero says the chemical approach is the simplest and least invasive.
But what about the prospect of the immune system rejecting the alien tissue? Robert White’s monkey died because its head was rejected by its new body. William Mathews, chairman of the AANOS, says he doesn’t think this would be a major problem today. He says that because we can use drugs to manage the acceptance of large amounts of tissue, such as a leg or a combined heart and lung transplant, the immune response to a head transplant should be manageable. “The system we have for preventing immune rejection and the principles behind it are well established.”

Happy 15th Birthday Chandra X-Ray Observatory
Fifteen years ago, NASA’s Chandra X-ray Observatory was launched into space aboard the Space Shuttle Columbia. Since its deployment on July 23, 1999, Chandra has helped revolutionize our understanding of the universe through its unrivaled X-ray vision.
Chandra, one of NASA’s current “Great Observatories,” along with the Hubble Space Telescope and Spitzer Space Telescope, is specially designed to detect X-ray emission from hot and energetic regions of the universe.
With its superb sensitivity and resolution, Chandra has observed objects ranging from the closest planets and comets to the most distant known quasars. It has imaged the remains of exploded stars, or supernova remnants, observed the region around the supermassive black hole at the center of the Milky Way, and discovered black holes across the universe. Chandra also has made a major advance in the study of dark matter by tracing the separation of dark matter from normal matter in collisions between galaxy clusters. It is also contributing to research on the nature of dark energy.
Chandra orbits far above Earth’s X-ray absorbing atmosphere at an altitude up to 139,000 km (86,500 mi), allowing for long observations unobscured by Earth’s shadow. When it was carried into space in 1999, it was the largest satellite ever launched by the shuttle.
To celebrate this incredible instrument’s 15th birthday, the Sifter has compiled 15 standout photos Chandra helped capture over the years. Click here to see more Chandra X-ray Observatory images.
