This new Hubble image shows the spiral galaxy Messier 83, otherwise known as the Southern Pinwheel Galaxy. This galaxy is dramatic and mysterious; it has hosted a large number of supernova explosions, and is thought to have a double nucleus lurking at its core. http://spacetelescope.org/news/heic1403/ AND http://infinity-imagined.tumblr.com/post/73545042127/spiral-galaxy-m83
Os cálculos batem: nosso universo pode ser um holograma
But, on the other hand, every one who is seriously involved in the pursuit of science becomes convinced that a spirit is manifest in the laws of the Universe—a spirit vastly superior to that of man, and one in the face of which we with our modest powers must feel humble. ~ Albert Einstein
Crab Nebula, by Hubble Space Telescope - This is a mosaic image, one of the largest ever taken by NASA's Hubble Space Telescope of the Crab Nebula, a six-light-year-wide expanding remnant of a star's supernova explosion. Japanese and Chinese astronomers recorded this violent event nearly 1,000 years ago in 1054, as did, almost certainly, Native Americans. - Portal:Space/Featured.
Astronomers have found evidence for what is likely one of the most extreme pulsars, or rotating neutron stars, ever detected. The source exhibits properties of a highly magnetized neutron star, or magnetar, yet its deduced spin period is thousands of times longer than any pulsar ever observed. For decades, astronomers have known there is a dense, compact source at the center these remains of a supernova explosion located about 9,000 light years from Earth. Image credit: X-ray…
