Previous observations have revealed curling filaments that stretch out from its main body and carve out a cosmic question mark in the sky (<a href=\"http:\/\/www.spacetelescope.org\/news\/heic1013\/\" target=\"_blank\">heic1013<\/a>), the dark tendrils encircling a brightly glowing centre.<\/p>\n<p>An international team of scientists, led by astronomers from the University of Cambridge, UK, have now used new observations from the NASA\/ESA Hubble Space Telescope to explore this thread-like structure in more detail. They found that each of the dusty filaments has a width of about 200 light-years, and a density some 10 times greater than the surrounding gas. These filaments knit together and spiral inwards towards the centre of NGC 4696, connecting the galaxy\u2019s constituent gas to its core.<\/p>\n<p><span class=\"embed-youtube\" style=\"text-align:center; display: block;\"><iframe loading=\"lazy\" class=\"youtube-player\" width=\"1600\" height=\"900\" src=\"https:\/\/www.youtube.com\/embed\/jUOMvp10pUo?version=3&#038;rel=1&#038;showsearch=0&#038;showinfo=1&#038;iv_load_policy=1&#038;fs=1&#038;hl=en&#038;autohide=2&#038;wmode=transparent\" allowfullscreen=\"true\" style=\"border:0;\" sandbox=\"allow-scripts allow-same-origin allow-popups allow-presentation allow-popups-to-escape-sandbox\"><\/iframe><\/span><\/p>\n<p style=\"padding-left: 30px;\"><em>This video pans over NASA\/ESA Hubble Space Telescope observations of the massive galaxy NGC 4696, which lies about 150 million light-years from Earth.\u00a0Credit: ESO\/L.

At the centre of NGC 4696 lurks an active supermassive black hole. This floods the galaxy\u2019s inner regions with energy, heating the gas there and sending streams of heated material outwards.<\/p>\n<p>It appears that these hot streams of gas bubble outwards, dragging the filamentary material with them as they go. The galaxy\u2019s magnetic field is also swept out with this bubbling motion, constraining and sculpting the material within the filaments.<\/p>\n<p><figure id=\"attachment_13576\" aria-describedby=\"caption-attachment-13576\" style=\"width: 500px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/www.spacetelescope.org\/images\/heic1621b\/\" target=\"_blank\"><img loading=\"lazy\" decoding=\"async\" data-attachment-id=\"13576\" data-permalink=\"https:\/\/hobbyspace.com\/Blog\/?attachment_id=13576\" data-orig-file=\"https:\/\/hobbyspace.com\/Blog\/wp-content\/uploads\/2016\/12\/heic1621b1.jpg\" data-orig-size=\"700,657\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;NASA, ESA, Digitized Sky Survey&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;This ground-based image shows the galaxy NGC 4696 and its surroundings.&quot;,&quot;created_timestamp&quot;:&quot;1480608000&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;Wide-field image of NGC 4696 (ground-based image)&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"Wide-field image of NGC 4696 (ground-based image)\" data-image-description=\"\" data-image-caption=\"&lt;p&gt;This ground-based image shows the galaxy NGC 4696 and its surroundings.&lt;\/p&gt;\n\" data-large-file=\"https:\/\/hobbyspace.com\/Blog\/wp-content\/uploads\/2016\/12\/heic1621b1.jpg\" class=\"wp-image-13576\" src=\"http:\/\/hobbyspace.com\/Blog\/wp-content\/uploads\/2016\/12\/heic1621b1.jpg\" alt=\"This ground-based image shows the galaxy NGC 4696 and its surroundings.\" width=\"500\" height=\"469\" srcset=\"https:\/\/hobbyspace.com\/Blog\/wp-content\/uploads\/2016\/12\/heic1621b1.jpg 700w, https:\/\/hobbyspace.com\/Blog\/wp-content\/uploads\/2016\/12\/heic1621b1-300x282.jpg 300w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><\/a><figcaption id=\"caption-attachment-13576\" class=\"wp-caption-text\"><em>This ground-based image shows the galaxy NGC 4696 and its surroundings.
