Designations of stars (and other celestial bodies) is mediated by the International Astronomical Union (IAU). Many of the star names in use today were inherited from the time before the IAU existed. Other names, mainly for variable stars (including novae and supernovae), are being added all the time.
Approximately 10,000 stars are visible to the naked eye. Pre-modern catalogues listed only the brightest of these. Hipparchus in the 2nd century BC enumerated about 850 stars. Johann Bayer in 1603 listed about twice this number. Only a minority of these have proper names; all others are designated by numbers from various catalogues. Only in the 19th century did star catalogues list the naked-eye stars exhaustively. The most voluminous modern catalogues list on the order of a billion stars, out of an estimated total of 200 to 400 billion in the Milky Way.
Several hundred of the brightest stars have traditional names, most of which derive from Arabic, but a few from Latin.

The Let's Move! Cities, Towns and Counties (LMCTC) program celebrated a significant achievement today as the City of McAllen, Texas, became the first city nationwide to earn an "All-Star Community" designation. All-Star Communities are LMCTC participants that have instituted new evidence-based policy strategies after completing the five LMCTC goals. McAllen was recognized by the National League of Cities (NLC) — the nation's largest and most representative organization for city officials across America, and the lead partner for LMCTC — due to the bold steps the city has taken to create a healthier community. LMCTC is a major component of First Lady Michelle Obama's comprehensive Let's Move! initiative to ensure that kids can grow up healthy.

With a size of 2600 solar radii, it is the largest known star and also one of the most luminous known. It is located about 1.5 kiloparsecs (4.6×1016 km) or about 4,900 light years away from Earth. Unlike most stars, which occur in either binary or multiple star systems, VY CMa is a single star. It is categorized as a semiregular variable and has an estimated period of ...

Variable stars are designated using a variation on the Bayer designation format of an identifying label combined with the Latin genitive of the name of the constellation in which the star lies.See List of constellations for a list of constellations and the genitive forms of their names.The current naming system is: Stars with existing Greek letter Bayer designations are not given new designations..Otherwise, start with the letter R and go through Z..

In this gameplay video, you will see all 3 phases of the new game mode "Battle Station", played as the rebels. Attacking and taking out a Star Destroyer in Phase 1, playing as and rescuing R2-D2 from the Death Star during intense infantry combat in Phase 2 and lastly, blowing up the Death Star itself with no other than Luke Skywalker's Red Five in Phase 3. How much more iconic can it get? ^^ During the Capture Event for the Death Star DLC, a bunch of different (Star Wars related) YouTubers and I had the chance to play this upcoming expansion pack early.

Sirius is the brightest star in the night sky with a visual apparent magnitude of −1.46, almost twice as bright as Canopus, the next brightest star. The name Sirius is derived from the Ancient Greek Σείριος.The star has the Bayer designation α Canis Majoris (α CMa, or Alpha Canis Majoris). What the naked eye perceives as a single star is actually a binary star system, consisting of a white main sequence star of spectral type A1V, termed Sirius A, and a faint white dwarf companion of spectral type DA2, termed Sirius B. Sirius appears bright due to both its intrinsic luminosity and its closeness to the Earth. At a distance of 2.6 parsecs (8.6 light years), the Sirius system is one of our near neighbors. Sirius A is about twice as massive as the Sun and has an absolute visual magnitude of ...
My Review of the only good Borg figure I know of, besides the 2 variations (Hirogen and Cardassian).

Sirius is the brightest star in the night sky. With a visual apparent magnitude of −1.46, it is almost twice as bright as Canopus, the next brightest star. The name "Sirius" is derived from the Ancient Greek: Σείριος Seirios ("glowing" or "scorcher"). The star has the Bayer designation Alpha Canis Majoris (α CMa). What the naked eye perceives as a single star is actually a binary star system, consisting of a white main-sequence star of spectral type A1V, termed Sirius A, and a faint white dwarf companion of spectral type DA2, called Sirius B. The distance separating Sirius A from its companion varies between 8.2 and 31.5 AU. 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 astro...
Valley's Cardiac Surgery program has once again been recognized with a three-star rating - the highest designation of quality and clinical excellence - by the Society of Thoracic Surgeons. The 3 Stars were achieved in both isolated bypass and Aortic Valve Replacement categories. Only 12-15% of programs nationwide achieve this distinction in isolated bypass surgery, only 6% for AVR surgery, and only 2.4% received the three-star rating in both categories. Valley's Cardiac Program has now received this recognition in both 2012 and 2013.
"An ancient Hopi Indian prophecy states, "When the Blue Star Kachina makes its appearance in the heavens, the Fifth World will emerge". This will be the Day of Purification.

Become a Terral’s 2016 Newsletter Subscriber with all the benefits by subscribing at http://terral03.com Seismic, volcanic and magnetic North Pole migration indicators say Earth is moving through the final stages of the second earth change lull period for the 2015 Earth Orbit Cycle relative to the inbound Black Star now moving through the Libra Constellation just below the ecliptic plane. Contrary to what many critics are saying, year-over-year seismicity is actually lower than last year with 5-mag quake events remaining about the same. For those wondering, the 7.1 magnitude Alaskan Quake Event (USGS info) took place on Sunday and will be posted for Week 53 once the Seismic Chart is updated next Thursday for Volume 5 of Terral’s 2016 Newsletter.
