The Big Chandra Picture The Big Chandra Picture In more than a decade of operation, NASA's Chandra X-ray Observatory has transformed our view of the high-energy Universe with its ability to make exquisite X-ray images of star clusters, supernova remnants, galactic eruptions, and collisions between clusters of galaxies. As Chandra expands the realm of the known, it continues to raise new questions and point the way for future exploration. This photo blog presents some of Chandra's most spectacular images in a large and shareable format.

Two Suns? Twin Stars Could Be Visible From Earth By 2012 - StumbleUpon By Dean Praetorius | HuffingtonPost.com Earth could be getting a second sun, at least temporarily. Dr. Brad Carter, Senior Lecturer of Physics at the University of Southern Queensland, outlined the scenario to news.com.au. Betelgeuse, one of the night sky’s brightest stars, is losing mass, indicating it is collapsing. It could run out of fuel and go super-nova at any time. Pluto's Orbit This is a drawing showing the orbit of Pluto and the outer planets. It shows the planets on June 1, 1997. In the larger version at least, you can see dots next to the names indicating planet position. In 1997, Pluto was closer to the Sun than Neptune.

Experiment with Nature - StumbleUpon Definition: Refraction : re·frac·tion – [ri-frak-shuhn] The change of direction of a ray of light in passing obliquely from one medium into another in which its wave velocity is different Markus Reugels of Deutschland uses the properties of refraction to create beautiful miniature worlds inside drops of water.

The Pentagon has been working for nearly a decade on an audacious plan to strike anywhere on the planet in less than an hour. Thursday could prove to be the do-or-die moment for that plan.

Eight planets Mike Brown On August 24th 2006 the word "planet" was given its first-ever scientific definition by a vote of the International Astronomical Union. With the raising of a few yellow cards in Prague, Pluto was demoted from full-fledged planet to "dwarf planet." Eris, originally called 2003 UB313, sometimes called Xena, sometimes called the "10th planet," which in many ways precipitated this final debate, becomes the largest known dwarf planet. Stunning Images of Paint Being Dropped in Water The images that you see before you appear to be different things to different people. Because of my obsession with the National Geographic and the Discovery Channel, to me, the images below appear to be some newly discovered creatures from the deep sea or images released by NASA of newly discovered galaxies. These stunning images are taken by British photographer, Mark Mawson, who has been taking pictures for over 22 years and specializing in shooting under water scenes. For his Aqueous Series, he takes several drops of colored paint and drops it into a tank of water. As gravity goes to work, so does Mark Mawson.

Ensign Software - ESPL: Dances of the Planets The planets in the heavens move in exquisite orbital patterns, dancing to the Music of the Cosmos. There is more mathematical and geometric harmony than we realize. The idea for this article is from a book Larry Pesavento shared with me. Earth As Seen from Mars - Marvin the Martian's front lawn Marvin the Martian's front lawn - Franny Wentzel - Saturday, April 24th, 2010 : goo [previous] :: [next] This is the first image ever taken of Earth from the surface of a planet beyond the Moon. It was taken by the Mars Exploration Rover Spirit one hour before sunrise on the 63rd Martian day, or sol, of its mission. (March 8, 2004) The image is a mosaic of images taken by the rover's navigation camera showing a broad view of the sky, and an image taken by the rover's panoramic camera of Earth.

The most recent change was in 2006 when scientists reclassified Pluto as a new kind of object - a dwarf planet. Dwarf Planets: This new class of worlds helps us categorize objects that orbit the Sun but aren't quite the same as the rocky planets and gas giants in our solar system. There could be hundreds more of these small worlds far out there waiting to be discovered.

Mars as big as the Moon: No. Just, no. Oh, is it August already? That means it’s time for the nonsense that is the “Mars will be as big as the Moon” claims once again. Yup. I saw this is getting spread around on Facebook: August 27 at 00:30 Lift up your eyes and look up at the night sky. On this night, the planet Mars will pass just 34.65 million miles from the earth.
