... Simulation: A Disk Galaxy Forms . ... U. Washington ), N-Body Shop , NASA Advanced Supercomputing Explanation: How do galaxies like our Milky Way form? ... For our Milky Way Galaxy , however, big mergers may not be over -- recent evidence indicates that our large spiral disk Galaxy will collide and coalesce with the slightly larger Andromeda spiral disk galaxy in the next few billion years. ...

... Armagh Planetarium . ... Universe . ... October . ... Posted on October 21, 2010 | No Comments Galaxies, distant from us in space and time, have been in the news recently. ... No Comments If you love great articles on space and astronomy you are probably already following the Carnival of Space. ... Hello, IтАЩm Colin, welcoming you to Astronotes, the PlanetariumтАЩs official blog. Here you will find the latest news and views from the fascinating worlds of astronomy and space exploration. ...

... 2011 June 5 . Another Nearby Supernova in the Whirlpool Galaxy . ... Explanation: One of the brightest supernovas in recent years has just been recorded in the nearby Whirlpool galaxy (M51). Surprisingly, a seemingly similar supernova was recorded in M51 during 2005, following yet another one that occurred in 1994. ... Pictured above are two images of M51 taken with a small telescope: one taken on May 30 that does not show the supernova, and one taken on June 2 which does. ... About APOD | ...

... January 8, 2007 . ... SENTINEL CORRESPONDENT . Astronomers at UC Santa Cruz have discovered a surprisingly massive halo of bright, old stars around our galactic neighbor Andromeda, pushing the outer limits of the galaxy to 1.5 million light years, and teaching them how spiral galaxies behave. ... Younger stars may be remnants of a galaxy devoured, but older stars could have formed with the birth of the galaxy. ... http://www.santacruzsentinel.com/archive/2007/January/08/local/stories/03local.htm . ...

The Big Bang was not an explosion from a single point, with a center and an edge. ... Each dot represents a "galaxy". Two of the galaxies have a ring of red photons moving out from them. Most of the photons are cosmic microwave background photons that were present since the Big Bang but which have been traveling freely only since 0.0003 Gyr after the Big Bang. ... However, all parts of the Universe started with CMBR photons, not just the two green galaxies. ... FAQ | ...

... Confirm Dark Galaxy Existence . ... New evidence from NASA's Hubble Space Telescope and the Westerbork Synthesis Radio Telescope in the Netherlands has been used to rule out all but one of the ideas put forward to explain the existence of VIRGOHI 21, an intergalactic gas cloud 50 million light-years from the Earth. ... Are there more such dark galaxies out there? ... Credit: R. Minchin / Arecibo Observatory / Cardiff University / Isaac Newton Telescope / Westerbork Synthesis Radio Telescope . ...

... Galaxies in the Local Volume . ... Accurate distances are now available for the majority of these nearby galaxies, allowing us to visualise the Local Volume in 3D, study the local Hubble flow and its dispersion, the (baryonic) Tully-Fisher relation, the local star formation density, etc. Individual galaxies in the Local Volume can be studied in amazing detail across a large range of wavelengths (some stunning examples are compiled in the Multiwavelength Astronomy pages). ...

... June 24, 1999 . NGC 1365: A Nearby Barred Spiral Galaxy . ... Explanation: Many spiral galaxies have bars across their centers. Even our own Milky Way Galaxy is thought to have a bar , but perhaps not so prominent as the one in NGC 1365, shown above . ... NGC 1365 is a member of the Fornax Cluster of Galaxies . Because NGC 1365 is relatively nearby, simultaneous measurements of its speed and distance are possible, which help astronomers estimate how fast our universe is expanding . ...

... Armagh Observatory, College Hill, Armagh BT61 9DG, +44 (0)28 3752 2928 . ... The Sun has an activity cycle of around 11 years; at the peak of this cycle many solar storms occur, each one ejecting mass into the solar system greater than that of Earth's Mount Everest. ... It might seem strange, but astronomers think that most of the matter in our Galaxy does not emit light as our Sun does but instead comprises so-called "dark matter". ...

... It isn t often that astronomers look into space and see another pair of eyes staring back at them, but that s what we have here. These aren t the eyes of an alien, but a pair of galaxies nicknamed The Eyes because they look like a pair of white eyeballs glowing in the dark! ... At first view, the galaxies don t look a lot like eyes in this photo, but that s because this picture was taken with a very powerf
