Sirius Sirius appears bright because of both its intrinsic luminosity and its proximity to Earth. At a distance of 2.6 parsecs (8.6 ly), as determined by the Hipparcos astrometry satellite, the Sirius system is one of Earth's near neighbors; for Northern-hemisphere observers between 30 degrees and 73 degrees of latitude (including almost all of Europe and North America), it is the closest star (after the Sun) that can be seen with the naked eye. Sirius is gradually moving closer to the Solar System, so it will slightly increase in brightness over the next 60,000 years. After that time its distance will begin to recede, but it will continue to be the brightest star in the Earth's sky for the next 210,000 years. Sirius A is about twice as massive as the Sun and has an absolute visual magnitude of 1.42. It is 25 times more luminous than the Sun but has a significantly lower luminosity than other bright stars such as Canopus or Rigel. Observational history Kinematics
Aurignacian - Wikipedia Entrance to the Potočka Zijalka, a cave in the Eastern Karavanke, where the remains of a human residence dated to the Aurignacian (40,000 to 30,000 BP) were found by Srečko Brodar in the 1920s and 1930s. It was the first high-altitude Aurignacian site to be discovered that significantly influenced the knowledge of the culture The Aurignacian (/ɔːrɪɡˈneɪʃən/) is an archaeological tradition of the Upper Palaeolithic. It is associated with the earliest modern humans in Europe and their migration from the Near East. The type site is Aurignac, Haute-Garonne, south-west France. The oldest undisputed example of human figurative art, the Venus of Hohle Fels, comes from the Aurignacian. Main characteristics Association with modern humans Art Typical statuettes consist of women that are called Venus figurines. Aurignacian finds include bone flutes.

Cygnus (constellation) Cygnus contains Deneb, one of the brightest stars in the night sky and one corner of the Summer Triangle, as well as some notable X-ray sources and the giant stellar association of Cygnus OB2. One of the stars of this association, NML Cygni, is one of the largest stars currently known. The constellation is also home to Cygnus X-1, an distant X-ray binary containing a supergiant and unseen massive companion that was the first object widely held to be a black hole. Many star systems in Cygnus have known planets as a result of the Kepler Mission observing one patch of the sky, the patch is the area around Cygnus. Cygnus as depicted in Urania's Mirror, a set of constellation cards published in London c.1825. Surrounding it are Lacerta, Vulpecula and Lyra. In Polynesia, Cygnus was often recognized as a separate constellation. Cygnus culminates at midnight on 29 June, and is most visible in the evening from the early summer to mid-autumn in the Northern Hemisphere.
THE EGYPTIAN STAR OF BETHLEHEM. Excerpt from the book Secret Chamber The brightest of all the fixed stars is Sirius. Known to astronomers as Alpha Canis Major, it is the principal star of the constellation Canis Major (the Big Dog). The ancient Egyptians called it Septit, the Hebrews knew it as Sihor, to the Greeks as Sothis and also as the "the Dog Star" that followed Orion the Hunter. Sirius has a magnitude of -1.42, which makes it nine times more brilliant than a standard first magnitude star. It can even been seen in daylight with a telescope having an aperture of 12 mm. Plate 1: The star Sirius A in Canis Major Its colour is a brilliant white with a tinge of blue and purple. Plate 2: Sky region of the Duat Throughout recorded history, and probably long before, Sirius was the subject of much veneration and myth making throughout the world. Since earliest times the ancient Egyptian paid particular attention to Sirius, which they identified to the 'soul' of the Goddess Isis.

Is NASA Covering Up the 100-Year Starship? - FoxNews.com NASA appears to be debating a way to permanently colonize another planet, boldly going where no one has ever gone -- and where no one could come back, some fear.Paramount A NASA official may have made a 35-million-mile slip of the tongue. The director of NASA's Ames Research Center in California casually let slip mention of the 100-Year Starship recently, a new program funded by the super-secret government agency, DARPA. In a talk at San Francisco's Long Conversation conference, Simon “Pete” Worden said DARPA has $1M to spend, plus another $100,000 from NASA itself, for the program, which will initially develop a new kind of propulsion engine that will take us to Mars or beyond. There's only one problem: The astronauts won't come back. The 100-year ship would leave Earth with the intention of colonizing a planet, but it would likely be a one-way trip because of the time it takes to travel 35 million miles. But what is the Hundred Year Starship? Dr.
Evolutionary origin of religions The evolutionary origin of religions theorizes about the emergence of religious behavior during the course of human evolution. Nonhuman religious behaviour Humanity’s closest living relatives are common chimpanzees and bonobos. These primates share a common ancestor with humans who lived between four and six million years ago. Marc Bekoff, Professor Emeritus of Ecology and Evolutionary Biology at the University of Colorado, Boulder, argues that many species grieve death and loss. Setting the stage for human religion Increased brain size In this set of theories, the religious mind is one consequence of a brain that is large enough to formulate religious and philosophical ideas. During human evolution, the hominid brain tripled in size, peaking 500,000 years ago. Robin Dunbar argues that the critical event in the evolution of the neocortex took place at the speciation of archaic homo sapiens about 500,000 years ago. Tool use Development of language
Alien City Lights Could Signal E.T. Planets | Search for Extraterrestrial Intelligence & Civilizations | Artificial Lights on Alien Planets Astronauts in orbit around the Earth often gaze down on a world lit at night by city lights. Now researchers suggest that scientists could detect alien civilizations from similarly bright lights. Science fiction has long imagined entire planets covered with cities. Assuming that aliens need light to see at night much as we do, theoretical astrophysicist Abraham Loeb at Harvard University and astronomer Edwin Turner at Princeton University reasoned that extraterrestrial civilizations would switch on city lights during the hours of darkness on their world. "Both Ed and I were attending a conference in Abu Dhabi about novel ways to detect life, and we had a tour guide on a trip to the nearby emirate of Dubai who bragged that it was so bright at night that you could see it easily from space — that's what gave us the idea," Loeb told Astrobiology Magazine. Decline of radio Outer solar system searches "There are other things we could discover from such a search," Loeb said.
Inca Gods : The Gods of Incan Mythology Viracocha The supreme deity or god of Incan Mythology was the creator Viracocha. Viracocha was both the god who created the world and also a man who traveled the earth doing great deeds. Viracocha created the world and the sky with all it's stars and he brought the sun and the moon out of an island in lake Titicaca to light it. He then went to Tihuanaco and formed people and animals out of clay. According to Incan mythology, after travelling through the country instructing his people, Viracocha set off across the Pacific from the shores of Ecuador, walking on the waves. His form was that of a man and he was thus represented in images in temples. In additions to worshipping he deities, the Inca worshipped the numerous huacas -sacred places -which were everywhere throughout the Inca Empire.
Alien Civilizations in Universe Introduction This calculation is just a rough one because galaxies vary a lot. There are also things called globular clusters that can contain hundreds of thousands of stars. I will be talking about type 0, type 1, type 2 and type 3 civilizations here. Kardashev scale civilizations, type 0,1,2,3 civilizations and beyond Shortened link to video: ⊗ Kardashev scale civilizations, type 0,1,2,3 civilizations and beyond [our possible future, video + music]: The Number of Civilizations in Our Galaxy & the Universe To calculate the numbers of advanced alien civilizations in a galaxy that want to communicate with us we use a thing called the Drake Equation. I have seen a few worrying directions to the Fermi Paradox. In one scenario if we discover life on other planets in our solar system it would be bad news for up since it means a “filter” (of extinction) lies ahead of us. I don’t agree with either of these ideas. ☉ Quick snap shot of the life cycle of our sun Summary
Orion The constellation of stars called Orion is one of the most recognizable patterns of stars in the northern sky (i.e. look up, for example). According to Ancient Myths, Orion is named after the hunter who was in love with Merope, one of the Seven Sisters of the Pleiades. Merope, unfortunately, would have nothing to do with him, and thereafter Orion added misery to heartbreak by stepping on Scorpius, the scorpion. [The rule is: never cross a Scorpio!]. < has the traditional, uncontroversial information about the constellation. “Hanging down from Orion’s belt is his sword that is made up of three fainter stars. Other views include the fact that inasmuch as the Orion Nebula is a star-making factory of the first order < then perhaps a more appropriate description of that which is hanging down below Orion’s waist is that of a phallus.
