Bolshoi Simulation Introduction: The Bolshoi Simulation Watch version with music Visualization of the dark matter in 1/1000 of the gigantic Bolshoi cosmological simulation, zooming in on a region centered on the dark matter halo of a very large cluster of galaxies. Visualized by Chris Henze, NASA Ames Research Center. This visualization was narrated in the National Geographic TV special "Inside the Milky Way". It was used with the piece "Dark Matter" in Bjork's Biophilia concert. MACS J0717- New Image Exposes Violent Collision of Galaxies - Physics-Astronomy Astrophysicists at the National Radio Astronomy Observatory (NRAO) have collected data from a variety of devices to generate a stunning compound image of crashing galaxy clusters mutually identified as MACS J0717. MACS J0717 is about 5.4 billion light years away from Earth in the Auriga constellation. The composite makes this the record well-studied galaxy cluster, and the photo was issued at the 224th Meeting of the American Astronomical Society.
Speed of the Milky Way in Space As we all know, a galaxy is a massive ensemble of hundreds of millions of stars. The galaxy where we live in today is called the Milky Way. The name itself came from the ancient Greek galaxies kyklos, or ring of milk, due to its faint milky appearance. Our Milky Way is a large spiral galaxy. Sun Orbit Everything’s orbiting something it seems. The Moon goes around the Earth, and the Earth orbits the Sun. But did you know that the Sun orbits the Milky Way galaxy? Astronomers have calculated that it takes the Sun 226 million years to completely orbit around the center of the Milky Way. Planck reveals an almost perfect Universe / Planck / Space Science Cosmic microwave background seen by Planck Planck reveals an almost perfect Universe 21 March 2013 Acquired by ESA’s Planck space telescope, the most detailed map ever created of the cosmic microwave background – the relic radiation from the Big Bang – was released today revealing the existence of features that challenge the foundations of our current understanding of the Universe. The image is based on the initial 15.5 months of data from Planck and is the mission’s first all-sky picture of the oldest light in our Universe, imprinted on the sky when it was just 380 000 years old.
Wandering Stars - How to Calculate the Positions of the Planets How to Calculate the Positions of the Planets: An Overview This brief explanation describes the methods used in the simulation above to determine the Right Ascension (RA) and Declination (Dec) of the Sun, Mercury, Venus, Mars, Jupiter, and Saturn. It assumes some background in astronomy. However, there is a reasonably verbose glossary linked to what may be unfamiliar terms. Four Surprises in Planck’s New Map of the Cosmos : Out There By now you’ve probably heard about the amazing new cosmic snapshot from the European Space Agency’s Planck spacecraft. It is one of those scientific achievements so mind-boggling that you have to spend a bit of time with it to truly appreciate what you are seeing. This is relic radiation from when the universe was 370,000 years old, still all aglow from the Big Bang. The radiation has been traveling 13.8 billion years since then, across ever-expanding stretches of space, before landing in Planck’s detectors. Then it took a tremendous feat of imagination and insight to translate that noisy signal into a comprehensible map of what the universe looked like in its infancy. Lopsided universe: Planck’s new skymap shows that one half of the microwave background is brighter than the other, and the universe has a large cold spot.
Astronomers Find First Evidence Of Other Universes Our cosmos was “bruised” in collisions with other universes. Now astronomers have found the first evidence of these impacts in the cosmic microwave background. December 13, 2010 Is our universe merely one of billions? Evidence of the existence of 'multiverse' revealed for the first time by cosmic map Scientists studied radiation data gathered by Planck telescope Claim anomalies show gravitational pull from other universesCould be the first real evidence to support controversial theory By Rosie Taylor for the Daily Mail Published: 13:15 GMT, 19 May 2013 | Updated: 13:15 GMT, 19 May 2013 The first 'hard evidence' that other universes exist has been found by scientists. Cosmologists studying a map of the universe from data gathered by the Planck spacecraft have concluded that it shows anomalies that can only have been caused by the gravitational pull of other universes.
