In this article it states that, observations of the dense remnant of an exploded star have provided the first sign of a quantum effect on light passing through empty space. Light from the stellar remnant is polarized, meaning that its electromagnetic waves are oriented preferentially in a particular direction like light that reflects off the surface of water. That polarization is evidence of "Vacuum birefringence," a quantum effect first predicted 80 years ago caused by light interacting with the vacuum of space in a strong magnetic field. According to quantum electrodynamics, empty space isn't really empty. Under strong magnetic fields, light waves that wiggle along the direction of the magnetic field will travel slightly slower than light oscillating perpendicular to the direction of the magnetic field, which rotates the overall polarization of light coming from the star. Horizontally polarized light, for example, is sent to each pixel, but a filter lets only vertically polarized light escape. Using the Very Large Telescope in Chile, the scientists found that visible light from the neutron star was about 16 percent polarized, a result consistent with scientists' theories of vacuum birefringence.

Another crystal has been found inside a Russian meteorite. This crystal is called a quasicrystal and is only the third quasicrystal ever found. All three of the quasicrystals came from the same meteroite and were discovered in a eastern region of Russia. The quasicrystal is composed of aluminum, copper and iron atoms arranged in a pemtagon shaped pattern. The crystals had formed before they hit down in Earth's atmoshpere. Although this crystal is highly rare, companies have tinkered with using lab-made versions in everything from electronics to frying pan coatings.
https://www.sciencenews.org/article/third-kind-quasicrystal-found-russian-meteorite?mode=topic&context=60 Ancient cultures from nothern America gave full moons in each month names bases on the behaviors of their surroundings in that month.
January: Wolf Moon Named after the wolves that would come and feast on the villages food furing the month of January. February: Snow Moon The other names for this month are storm moon and hunger moon. The reason it is called the snow moon is due to the weather during the time of Feburary. March: Worm Moon Named after the worms that would apear on the freshly thawed ground after the month of February's snow. April: Pink Moon Named after the wildflower that began to bloom in April. May: Flower Moon Abundant blooms of flowers resulted in the naming of this moon. During the spring time is when the flowers bloom. April showers bring May flowers. June: Strawberry Moon In North America, June is the harvesting season for the strawberry, hence the name of the moon this month. July: Buck Moon Native male deer begin to regrow their antlers that they had shed in June. Another name for July is the thunder moon for the summer storms. August: Sturgeon Moon Due to the abundance of the sturgeon species in August, native American fishing tribes names the moon after the species. Also, called the red moon due to the color from the summer haze. September: Harvest Moon This is the most commonly known moon name due to the fact that it goes along with the auntumn equinox after the crops are gathered. October: Hunters Moon Due to anicent native American hunters, they named the october moon after the best time to hunt summer- fattened aminals such as, deer and fox. November: Beaver Moon There is no certain answer on how this month got it's name. The debate is between the season of beavers building their damns and the season of Native Americans heavily settign up beaver traps during November. Another name is the Frost Moon. Personally, I think the Frost Moon fits November better. December: Cold Moon Nothing fits December better, the coming of winter tops off the last month of the years full moon. The Cold Moon suits december nicely, not only because it is a cold month but because it is the ending of another year. The Blue Moon Last but not least, the blue moon. There is no known reason as to why it is called BLUE moon. However, the reason that there is an additional moon name is for the time that you see two full moons in one month. These moon happen every two and a half years or so and they typically are not constantly with in the same month. http://science.nationalgeographic.com/science/space/solar-system/full-moon-article/ |
