Types of solar and lunar eclipsesAn eclipse is an astronomical event where one celestial body partially or totally covers another celestial object. This happens when the eclipsing body comes between the observer and the eclipsed object like in the case of a solar eclipse, or when the eclipsing body temporarily cuts off the source of illumination of the eclipsed object, like during a lunar eclipse. Types of Eclipses With Animations: All Eclipses 1900-2099 Observers from Earth can see two types of eclipses – eclipses of the Sun (solar eclipses), and eclipses of the Moon (lunar eclipses). The term eclipse also finds its roots in ancient Greek – it comes from the word ékleipsis, meaning to fail or abandoned. Eclipses, solar and lunar, have fascinated scientists and lay people for centuries. Solar Eclipses Infographic: Types of solar eclipses. With Animations: Solar Eclipses 1900-2099 There are 3 kinds of solar eclipses: total, partial, annular. Total Solar Eclipses With Animations: Total Solar Eclipses 1900-2099 Lunar Eclipses
The Incredible Beauty of the Orion NebulaLearn about the beauty of the Orion Nebula. Photo: NASA Goddard Space Flight Center The Orion Nebula is one of the brightest in the night sky and lies south of Orion’s Belt. Photo: NASA, ESA, M. The area in the image above is a called the Trapezium and is an area of very young stars; six of the main stars that can often be seen from earth on a clear night. Photo: NASA, ESA, M. The Orion Nebula has been seen from earth for thousands of years. Photo: NASA/JPL-Caltech/STScI The Orion Nebula includes neutral clouds of gas and dust, ionized gas, associations of stars and reflection nebulae, which are clouds of dust reflecting the light of stars. Photo: Steve Black Orion is a stellar nursery where stars are born, and there are about 700 stars in various stages of birth within it.

2011 Solar & Lunar Eclipse Skywatching Guide | Eclipses, Moon & Sun Photos | Skywatching, Amateur AstronomyThere will be two total lunar eclipses and four partial solar eclipses in 2011. January 4 Partial Solar Eclipse This partial eclipse will be visible at sunrise in northwestern Europe and northwestern Africa, at midday in northeastern Africa and the Middle East, and at sunset in central Asia. Times of maximum eclipse and magnitudes at major cities: June 1 Partial Solar Eclipse This partial eclipse is visible mainly in the high Arctic. Times of maximum eclipse and magnitude at major cities: June 15 Total Lunar Eclipse This will be an almost central total lunar eclipse. July 1 Partial Solar Eclipse This partial eclipse is visible only in a small area of ocean near Antarctica, south of Africa November 25 Partial Solar Eclipse This partial eclipse will be visible from southern South Africa, Antarctica, and New Zealand. December 10 Total Lunar Eclipse This total eclipse is well placed for observers in eastern Asia, Australia, and northwestern North America. Source: RASC Observer's Handbook 2011
Stephen Hawking: 'There is no heaven; it's a fairy story' | ScienceA belief that heaven or an afterlife awaits us is a "fairy story" for people afraid of death, Stephen Hawking has said. In a dismissal that underlines his firm rejection of religious comforts, Britain's most eminent scientist said there was nothing beyond the moment when the brain flickers for the final time. Hawking, who was diagnosed with motor neurone disease at the age of 21, shares his thoughts on death, human purpose and our chance existence in an exclusive interview with the Guardian today. The incurable illness was expected to kill Hawking within a few years of its symptoms arising, an outlook that turned the young scientist to Wagner, but ultimately led him to enjoy life more, he has said, despite the cloud hanging over his future. "I have lived with the prospect of an early death for the last 49 years. "I regard the brain as a computer which will stop working when its components fail. The book sold a reported 9 million copies and propelled the physicist to instant stardom.
Galaxy Zoo: HubbleThe Solar System: The Sun, Planets, Dwarf Planets, Moons, Asteroids, Comets, Meteors, and Solar System FormationOur solar system is filled with a wide assortment of celestial bodies - the Sun itself, our eight planets, dwarf planets, and asteroids - and on Earth, life itself! The inner solar system is occasionally visited by comets that loop in from the outer reaches of the solar system on highly elliptical orbits. In the outer reaches of the solar system, we find the Kuiper Belt and the Oort cloud. Still farther out, we eventually reach the limits of the heliosphere, where the outer reaches of the solar system interact with interstellar space. Solar system formation began billions of years ago, when gases and dust began to come together to form the Sun, planets, and other bodies of the solar system.
The Nine Planets Solar System TourMoon Phases SoftwareDear Friend, f you are interested in ... (Check any that apply to you.) ... and you want to predict, research, or track the moon, you will love this software! Thousands of people from around the world -- people with the same interests, hobbies or careers you selected -- have taken advantage of the benefits QuickPhase Pro provides. In the past, finding the phases of the moon or position of the moon was either inconvenient, or time-consuming, or hard to understand ... or all three. You can view all kinds of past or future moon data without complicated, expensive programs, technical jargon, or slow, tedious Internet research. I'll tell you all about the features of QuickPhase Pro in a minute, but first... Here's What I Discovered When I started looking for moon phase data, I immediately jumped on the Internet looking for free info. ... none of what I found was a real solution for viewing moon phases. What is the "Ideal Moon Phase Program"? If you are like me, you want a solution that: Nope! P.S.
Evolution of the Universe - GigaPan Time MachineJump to: From GigaPan Time Machine Direct Cosmological Simulations of the Growth of Black Holes and Galaxies This timelapse shows the distribution of matter in a simulated universe on large scales. The density of matter is shown on a false color scale, with the densest regions in yellow and the least dense in red and black. As the universe evolves from early times (it starts at an age of 10 million years after the Big Bang) the initially small fluctuations grow through the action of gravity until in the last frame (which represents the universe 14 billion years later, at redshift z=0, the present day) there are large clusters of galaxies present with vast, mostly empty spaces in between. To carry out the simulation the equations of gravity, hydrodynamics, radiative cooling, and models for star formation and black hole growth were solved in parallel on a system of 100 million particles.
