Observational history[edit] The Pleiades are a prominent sight in winter in both the Northern Hemisphere and Southern Hemisphere, and have been known since antiquity to cultures all around the world, including the Māori, Aboriginal Australians, the Persians, the Arabs (known as Thurayya), the Chinese, the Japanese, the Maya, the Aztec, and the Sioux and Cherokee. In Tamil culture this star cluster is attributed to Lord Murugan (Lord Murugan raised by the six sisters known as the Kārththikai Pengal and thus came to be known as Kārtikeyan). In Sanskrit he is known as Skanda. The Nebra sky disk, dated c. 1600 BC. The Babylonian star catalogues name the Pleiades MUL.MUL or "star of stars", and they head the list of stars along the ecliptic, reflecting the fact that they were close to the point of vernal equinox around the 23rd century BC. In Japan, the constellation is mentioned under the name Mutsuraboshi ("six stars") in the 8th century Kojiki and Manyosyu documents. ). Distance[edit] Related:  Collection

Chimera (genetics) A chimera (also spelled chimaera) is a single organism composed of genetically distinct cells. This can result in male and female organs, two different blood types, or subtle variations in form.[1] Animal chimeras are produced by the merger of multiple fertilized eggs. In plant chimeras, however, the distinct types of tissue may originate from the same zygote, and the difference is often due to mutation during ordinary cell division. Normally, chimerism is not visible on casual inspection; however, it has been detected in the course of proving parentage. Another way that chimerism can occur in animals is by organ transplantation, giving one individual tissues that developed from two different genomes. For example, a bone marrow transplant can change someone's blood type. This condition is either inherited or it is acquired through the infusion of allogeneic hematopoietic cells during transplantation or transfusion. Tetragametic chimerism is a form of congenital chimerism.

Arcturus Arcturus is a type K1.5 IIIpe orange giant star, with an absolute magnitude of −0.30. It has likely exhausted its hydrogen from the core and is currently in its active hydrogen shell burning phase. It will continue to expand before entering horizontal branch stage of its life cycle. Observational history[edit] As one of the brightest stars in the sky, Arcturus has been significant to observers since antiquity. According to the Hipparcos satellite, Arcturus is 36.7 light years (11.3 parsecs) from Earth, relatively close in astronomical terms. Visibility[edit] Arcturus has a visual magnitude of −0.04, making it the brightest star north of the celestial equator, and the fourth brightest star in the night sky.[9] However, Alpha Centauri is a bright binary star, whose unresolved components to the naked eye are both fainter than Arcturus. Arcturus is visible from both Earth's hemispheres as it is located 19° north of the celestial equator. Physical properties[edit] Oscillations[edit] China[edit]

Universal Time Universal Time (UT) is a time standard based on the rotation of the Earth. It is a modern continuation of Greenwich Mean Time (GMT), i.e., the mean solar time on the Prime Meridian at Greenwich, and GMT is sometimes used loosely as a synonym for UTC. In fact, the expression "Universal Time" is ambiguous (when accuracy of better than a few seconds is required), as there are several versions of it, the most commonly used being UTC and UT1 (see below). Universal Time and standard time[edit] Prior to the introduction of standard time, each municipality throughout the civilized world set its official clock, if it had one, according to the local position of the Sun (see solar time). Standard time zones of the world since September 20, 2011, instructions for converting UTC to or from local times are on the bottom, using addition or subtraction During the period between 1848 to 1972, all of the major countries adopted time zones based on the Greenwich meridian.

Crab Nebula Chandra, Hubble, and Spitzer image NGC 1952 At X-ray and gamma ray energies above 30 keV, the Crab is generally the strongest persistent source in the sky, with measured flux extending to above 10 TeV. Located at a distance of about 6,500 light-years (2 kpc) from Earth, the nebula has a diameter of 11 light years (3.4 pc, corresponding to an apparent diameter of some 7 arc minutes) and expands at a rate of about 1,500 kilometers per second (0.5% c). At the center of the nebula lies the Crab Pulsar, a neutron star 28–30 km across with a spin rate of 30.2 times per second, [6] which emits pulses of radiation from gamma rays to radio waves. Origins and history of observation[edit] Reproduction of the drawing by Lord Rosse (1844), the first depiction of the nebula (color-inverted in order to appear white-on-black) The creation of the Crab Nebula corresponds to the bright SN 1054 supernova recorded by Chinese astronomers in AD 1054.[9] Physical conditions[edit] The Crab Nebula video by NASA

Brotherhood of the Snake When the Earth descended into the third dimension and the 'Planetary Logos' (the soul of the Earth) entered a new cycle of experience, humans reached their zenith in polar consciousness. To this day, the cycle of opposites and '- the feeling of separation has prevailed. ~One could say that when Atlantis and its continent sank, the ,Earth left the fourth and fifth dimensions to enter the realm of -the three dimensional material structure. With the descent into the third dimension, the remaining human race .lost consciousnes's of the Oneness of all things. Polarity ,awareness took over and instead of harmony, more and more opposites entered the consciousness and the actions of .human beings. Shambhala was the seat of the Evocation of the Masters of Wisdom,, Agartha was the seat of the Invocation of the Masters of Wisdom. In the outer world, each Brotherhood thought of the other one as the dark Brotherhood, the Black Magicians. World politics and religions have the same objective.

C/2010 X1 Comet C/2010 X1 (Elenin) is a long-period comet discovered by Russian amateur astronomer Leonid Elenin on December 10, 2010, through remote control of the International Scientific Optical Network's robotic observatory near Mayhill in the U.S. state of New Mexico. The discovery was made using the automated asteroids discovery program CoLiTec. At the time of discovery, the comet had an apparent magnitude of 19.5,[2] making it about 150,000 times fainter than can be seen with the naked eye.[5] The discoverer, Leonid Elenin, originally estimated that the comet nucleus was 3–4 km in diameter,[6] but more recent estimates place the pre-breakup size of the comet at 2 km.[7] Comet Elenin started disintegrating in August 2011,[8] and as of mid-October 2011 was not visible even using large ground-based telescopes.[9] Brightness[edit] Original and future orbit[edit] References[edit] External links[edit]

Erinyen Zwei Rachegöttinnen (Zeichnung aus dem 19. Jahrhundert nach einer antiken Vase) Die Erinyen oder Erinnyen ( griechisch Ἐρīνύς , Pl.: Ἐρινύες ) – bei den Griechen auch als Maniai , „die Rasenden“, später als Eumeniden (Εὐμενίδες), bei den Römern als Furien bezeichnet – sind in der griechischen Mythologie drei Rachegöttinnen: Alekto ( Ἀληκτώ ), „die (bei ihrer Jagd) Unaufhörliche“ Megaira ( Μέγαιρα , deutsch auch „Megäre“), „der neidische Zorn“. Im übertragenen Sinne wird ihr Name auch für eine böse, wütende Frau verwendet, eben für eine Furie (römisches Pendant einer Erinye). Sie stellen die personifizierten Gewissensbisse dar.

Taurus (constellation) Taurus is one of the constellations of the zodiac, which means it is crossed by the plane of the ecliptic. Its name is a Latin word meaning "bull", and its astrological symbol is a stylized bull's head: (Unicode ♉). Taurus is a large and prominent constellation in the northern hemisphere's winter sky. It is one of the oldest constellations, dating back to at least the Early Bronze Age when it marked the location of the Sun during the spring equinox. This constellation forms part of the zodiac, and hence is intersected by the ecliptic. The recommended three-letter abbreviation for the constellation, as adopted by the International Astronomical Union in 1922, is "Tau".[2] The official constellation boundaries, as set by Eugène Delporte in 1930, are defined by a polygon of 26 segments. The constellation Taurus as it can be seen by the naked eye.[9] The constellation lines have been added for clarity. A degree to the northwest of ζ Tauri is the Crab Nebula (M1), a supernova remnant.

99942 Apophis 99942 Apophis (/əˈpɒfɪs/, previously known by its provisional designation 2004 MN4) is a near-Earth asteroid that caused a brief period of concern in December 2004 because initial observations indicated a probability of up to 2.7% that it would hit Earth in 2029. Additional observations provided improved predictions that eliminated the possibility of an impact on Earth or the Moon in 2029. However, a possibility remained that during the 2029 close encounter with Earth, Apophis would pass through a gravitational keyhole, a small region no more than about 800 m (half a mile) wide,[7] that would set up a future impact on April 13, 2036. This possibility kept the asteroid at Level 1 on the Torino impact hazard scale until August 2006, when the probability that Apophis would pass through the keyhole was determined to be very small. During the short time when it had been most concerning, Apophis set the record for highest rating on the Torino Scale, reaching level 4.[8] Close approaches[edit]

Proper motion Relation between proper motion and velocity components of an object. At emission, the object was at distance d from the Sun, and moved at angular rate μ radian/s, that is, μ = vt / d with vt = velocity transverse to line of sight from the Sun. (The diagram illustrates an angle μ swept out in unit time at tangential velocity vt.) Introduction[edit] This motion is caused by the true movement of the stars relative to the Sun and solar system through space. The Sun travels in a nearly circular orbit (the solar circle) about the center of the Milky Way at a speed of about 220 km/s at a radius of 8 ± 0.65 kpc from the center,[4][5] which can be taken as the rate of rotation of the Milky Way itself at this radius.[6][7] The proper motion is measured by two quantities: the position angle and the proper motion itself. Proper motion may also be given by the angular changes per year in the right ascension (μα) and declination (μδ). where δ is the declination. Usefulness in astronomy[edit]

The Stellar Sisters Happy Matariki everyone! It’s that time of the year when we approach the shortest day and Matariki appears low in the East in our morning sky just before the sunrise. To find it follow the line of the stars from Orion’s belt (Tautoru in Maori) towards the North – past a red star (Aldebaran) and to a small clump of stars; the “Eyes of God” or Matariki. Matariki as seen by Spitzer Space Telescope Depending on eyesight and viewing conditions people are usually able to make out between 7 and 14 stars within this cluster with the naked eye, although in reality there are over 1000 members. Known as the Pleiades, the daughters of the titan Atlas in greek folklore and as Subaru in Japan, this cluster is almost always associated with celebrations of rebirth and regeneration, most likely due to its appearance’s proximity to the Northern solstice (shortest day), when the tide of Winter turns and we begin to move towards warmer months once again. Main Matariki stars So why do I include this?
