The Universe: The constellations 2 - History channel. Video imported from 'leosupercluster' YouTube channel: www.youtube.com Text imported from 'leosupercluster' YouTube channel: " In modern astronomy, a constellation is an internationally defined area of the celestial sphere. Historically, the term was also used to refer to a perceived pattern formed by prominent stars within apparent proximity to one another, and this practice is still common today. A constellation is a group of celestial bodies, usually stars, which appear to form a pattern in the sky. Astronomers today still utilize the term, though the current system focuses primarily on constellations as grid-like segments of the celestial sphere rather than as patterns. A star-pattern that is not offically classed as a constellation is refered to as an asterism. Typically, the modern constellations share the names of their greco-roman predecessors, such as Orion, Leo and Scorpius. While such celestial formations were originally linked to a mythical event, creature or person, the categorization of the night sky into recognizable patterns was important in early land and naval navigation prior to the invention of the compass during the Age of Discovery. With the technical advancement of astronomy, it became important to move from a pattern-based system of constellations to one based on area-mapping, which led to several historic formations becoming obsolete.

!9# Fifty New Alien Worlds Revealed - September 12, 2011

HARPS www.eso.org "European astronomers have announced the discovery of more 50 new planets beyond our solar system, including 16 that are just a notch above our own planet in mass. They say their record-breaking findings suggest that more than half of the stars like our sun possess planets, and that many of those worlds are lighter than Saturn. The pick of the litter is a planet that's already attracted a big share of the spotlight: HD 85512 b, a world at least 3.6 times as massive as Earth that's located 36 light-years away in the constellation Vela. HD 85512 b is the only one of the 16 super-Earths on today's list that is located in its star system's habitable zone. That's the area around a star where scientists believe water could exist in liquid form, which would make a rocky planet potentially livable. HD 85512 b's status came to light a couple of weeks ago in a paper submitted to the journal Astronomy and Astrophysics, but the team behind the discovery provided more details about that super-Earth and the dozens of other worlds in papers presented today at the Extreme Solar Systems II conference in Wyoming. The findings came from the team behind the High Accuracy Radial Velocity Planet Searcher, or HARPS, which is installed at the European Southern Observatory's 11.8-foot (3.6-meter) La Silla Observatory in Chile. "The detection of HD 85512 b is far from the limit of HARPS, and demonstrates the possibility of discovering other super-Earths in the habitable zones ...

A month-by-month guide to the night sky in the year 2004, together with a starfinder to make skywatching easier. The booklet features 12 monthly charts showing the night sky objects visible above the horizon late in the evening, whilst notes opposite each chart describe the visibility of the planets and the phases of the moon. The guide includes information on sunset, sunrise and nautical twilight times, in addition to a table highlighting the principal meteor showers in 2004, and notes on other important events in the astronomical calendar. The starfinder or planisphere is a device which can tell you the positions of the stars at any time, on any day of any year. It works in a very simple way: just dial in the date and time by rotating the inner plastic disk, the time, until it lines up with the relevant month and day of the year calibrated on the outer ring. The portion of sky shown on the starfinder will show the arrangement of the stars above you. An essential piece of kit for any skywatcher.
