But gravity isn&#8217;t the only force at work. Both turbulence and magnetic fields battle gravity, either by stirring things up or by channeling and restricting gas flows, respectively. New research focusing on magnetic fields shows that they influence star formation on a variety of scales, from hundreds of lightyears down to a fraction of a lightyear.<br \/>\n<\/em><em>Science Daily: www.sciencedaily.com\/releases\/2015\/03\/150330122613.htm<br \/>\n<\/em><em>Nature: http:\/\/www.nature.com\/nature\/journal\/vaop\/ncurrent\/full\/nature14291.html<\/em><\/p>\n<p><strong>\u00a04\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 How Slippery Is Dark Matter?<\/strong>\u00a0Mar 30, &#8217;15<br \/>\n<a href=\"http:\/\/abergavennyas.org.uk\/wp-content\/uploads\/2015\/04\/How-slippery.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-1235\" src=\"http:\/\/abergavennyas.org.uk\/wp-content\/uploads\/2015\/04\/How-slippery.jpg\" alt=\"How slippery\" width=\"538\" height=\"436\" srcset=\"http:\/\/abergavennyas.org.uk\/wp-content\/uploads\/2015\/04\/How-slippery.jpg 538w, http:\/\/abergavennyas.org.uk\/wp-content\/uploads\/2015\/04\/How-slippery-300x243.jpg 300w, http:\/\/abergavennyas.org.uk\/wp-content\/uploads\/2015\/04\/How-slippery-150x121.jpg 150w, http:\/\/abergavennyas.org.uk\/wp-content\/uploads\/2015\/04\/How-slippery-400x324.jpg 400w\" sizes=\"auto, (max-width: 538px) 100vw, 538px\" \/><\/a><\/p>\n<p><em>Dozens of galaxy cluster collisions confirm that dark matter particles probably slip right past each other within messy cluster mergers.<br \/>\nSky &amp; Telescope: http:\/\/www.skyandtelescope.com\/astronomy-news\/how-slippery-is-dark-matter-0330201534\/<\/em><\/p>\n<p><strong>5\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Dark matter even darker than once thought\u00a0<\/strong>\u00a0 Mar 26, &#8217;15\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 ESA\/Hubble Information Centre<br \/>\n<em>Astronomers have studied how dark matter in clusters of galaxies behaves when the clusters collide.

A European research team has found that the rotation axes of the central supermassive black holes in a sample of quasars are parallel to each other over distances of billions of light-years. The team has also found that the rotation axes of these quasars tend to be aligned with the vast structures in the cosmic web in which they reside.<\/p>\n<p><b>\u00a0&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;<\/b><\/p>\n","protected":false},"excerpt":{"rendered":"<p>2015 Cosmology Posts News Items discussed at the November 9th Cosmology Meeting Comets &#8211; Lovejoy &amp; alcohol Date 24th October;\u00a0 \u00a0Source NASA\/Goddard Space Centre;\u00a0\u00a0 Links:\u00a0 Science Daily\u00a0 :\u00a0 ZME Science Comet &#8211; Rosetta &amp; oxygen Date \u00a029th October;\u00a0\u00a0 Source University of Bern;\u00a0\u00a0 Links:\u00a0 Science Daily\u00a0 :\u00a0 ZME Science Chemicals &#8211; Common chemical makeup at largest [&hellip;]<\/p>\n","protected":false},"author":46,"featured_media":0,"parent":200,"menu_order":0,"comment_status":"open","ping_status":"open","template":"","meta":{"_s2mail":"no","ngg_post_thumbnail":0,"footnotes":""},"class_list":["post-1492","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"http:\/\/abergavennyas.org.uk\/index.php?rest_route=\/wp\/v2\/pages\/1492","targetHints":{"allow":["GET"]}}],"collection":[{"href":"http:\/\/abergavennyas.org.uk\/index.php?rest_route=\/wp\/v2\/pages"}],"about":[{"href":"http:\/\/abergavennyas.org.uk\/index.php?rest_route=\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"http:\/\/abergavennyas.org.uk\/index.php?rest_route=\/wp\/v2\/users\/46"}],"replies":[{"embeddable":true,"href":"http:\/\/abergavennyas.org.uk\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=1492"}],"version-history":[{"count":3,"href":"http:\/\/abergavennyas.org.uk\/index.php?rest_route=\/wp\/v2\/pages\/1492\/revisions"}],"predecessor-version":[{"id":1496,"href":"http:\/\/abergavennyas.org.uk\/index.php?rest_route=\/wp\/v2\/pages\/1492\/revisions\/1496"}],"up":[{"embeddable":true,"href":"http:\/\/abergavennyas.org.uk\/index.php?rest_route=\/wp\/v2\/pages\/200"}],"wp:attachment":[{"href":"http:\/\/abergavennyas.org.uk\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=1492"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
