Although considered part of our Local Group of dozens of galaxies, WLM stands alone at the group\u2019s outer edges as one of its most remote members. In fact, the galaxy is so small and secluded that it may never have interacted with any other Local Group galaxy \u2014 or perhaps even any other galaxy in the history of the Universe.","src":"https:\/\/i0.wp.com\/hobbyspace.com\/Blog\/wp-content\/uploads\/2016\/03\/eso1610a1-1024x760.jpg?resize=350%2C200","width":350,"height":200},"classes":[]},{"id":13217,"url":"https:\/\/hobbyspace.com\/Blog\/?p=13217","url_meta":{"origin":16522,"position":4},"title":"ESO: Secrets of a giant space blob uncovered","author":"TopSpacer","date":"September 21, 2016","format":false,"excerpt":"A new report from the European Southern Observatory (ESO): ALMA Uncovers Secrets of Giant Space Blob\u00a0 An international team using ALMA, along with ESO\u2019s Very Large Telescope and other telescopes, has discovered the true nature of a rare object in the distant Universe called a Lyman-alpha Blob.

This simulation tracks the evolution of gas and dark matter using one of the latest models for galaxy formation running on the NASA Pleiades supercomputer. This view shows the distribution of gas within the dark matter halo, colour coded so that cold gas (mainly neutral hydrogen) appears red and hot gas appears white. Embedded at the centre of this system are two strongly star-forming galaxies, but these are surrounded by hot gas and many smaller satellite galaxies that appear as small red clumps of gas here. Lyman-alpha photons escape from the central galaxies and scatter off the cold gas associated with these satellites to give rise to an extended Lyman-alpha Blob.","src":"https:\/\/i0.wp.com\/hobbyspace.com\/Blog\/wp-content\/uploads\/2016\/09\/eso1632a1.jpg?resize=350%2C200","width":350,"height":200},"classes":[]},{"id":10930,"url":"https:\/\/hobbyspace.com\/Blog\/?p=10930","url_meta":{"origin":16522,"position":5},"title":"ESO: New galactic survey measuring dark matter distribution","author":"TopSpacer","date":"July 9, 2015","format":false,"excerpt":"Here's the latest\u00a0ESO\u00a0(European Southern Observatory) report: Huge New Survey to Shine Light on Dark Matter The first results have been released from a major new dark matter survey of the southern skies using ESO\u2019s VLT Survey Telescope (VST) at the Paranal Observatory in Chile.
