grobi<p>TOPIC> Sounds Of The Universe</p><p>"Hello everyone! In this topic, the visual stimuli are in the background, even if there will certainly be one or two beautiful pictures to see. Rather, it is about special sounds on our planet and elsewhere in space and acoustic representations of astronomical constellations, so-called sonifications. I really hope to bring a little joy to our visually impaired friends of the Fediverse with this collection and I am very grateful for any inspiration or suggestions for improvement from you!"</p><p>2024 March 25</p><p>Sonified: The Jellyfish Nebula Supernova Remnant<br> * Image Credit: X-ray (blue): Chandra (NASA) & ROSAT (ESA); Optical (red): DSS (NSF)<br> * Radio (green): VLA (NRAO, NSF) <br> * Sonification: NASA, CXC, SAO, K.

Although sound is a compression wave in matter and does not carry into empty space, interpretive sound can help listeners appreciate and understand a visual image of a supernova remnant in a new way. Recently, the Jellyfish Nebula (IC 443) has been sonified quite creatively. In the featured sound-enhanced video, when an imaginary line passes over a star, the sound of a drop falling into water is played, a sound particularly relevant to the nebula's aquatic namesake. Additionally, when the descending line crosses gas that glows red, a low tone is played, while green sounds a middle tone, and blue produces a tone with a relatively high pitch. Light from the supernova that created the Jellyfish Nebula left approximately 35,000 years ago, when humanity was in the stone age. The nebula will slowly disperse over the next million years, although the explosion also created a dense neutron star which will remain indefinitely.</p><p><a href="https://apod.nasa.gov/apod/ap240325.html" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">apod.nasa.gov/apod/ap240325.ht</span><span class="invisible">ml</span></a></p><p><a href="https://defcon.social/tags/space" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>space</span></a> <a href="https://defcon.social/tags/nebula" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>nebula</span></a> <a href="https://defcon.social/tags/sonification" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>sonification</span></a> <a href="https://defcon.social/tags/sound" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>sound</span></a> <a href="https://defcon.social/tags/astrophotography" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>astrophotography</span></a> <a href="https://defcon.social/tags/photography" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>photography</span></a> <a href="https://defcon.social/tags/science" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>science</span></a> <a href="https://defcon.social/tags/astronomy" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>astronomy</span></a> <a href="https://defcon.social/tags/nature" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>nature</span></a> <a href="https://defcon.social/tags/education" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>education</span></a></p>
