Using a radar-like scan, the sonification begins at the 12 o'clock position and sweeps clockwise. Changes in volume represent the differences in brightness the EHT observed around the event horizon of Sgr A*. The material that is closer to the black hole and hence moving faster corresponds to higher frequencies of sound. This sonification was processed in a special way to allow a listener to hear the data in 3D stereo sound, in which the sounds seem to start directly ahead and then move clockwise to one ear then the other as the sweep is made. </p><p>About the Sound:</p><p>This is a radar-like scan, starting from 12 o'clock and moving clockwise.</p><p>The brightness controls the volume and the radial position controls the frequencies that are present.</p><p>The emission from material closer to the black hole (which orbits faster) is mapped to higher frequencies.</p><p>The sound is rendered in binaural audio.

It is sucking in matter from a swirling disk -- a disk that is magnetized, it has now been confirmed. Specifically, the black hole's accretion disk has recently been seen to emit polarized light, radiation frequently associated with a magnetized source. Pictured here is a close-up of Sgr A*, our Galaxy's central black hole, taken by radio telescopes around the world participating in the Event Horizon Telescope (EHT) Collaboration. Superposed are illustrative curved lines indicating polarized light likely emitted from swirling magnetized gas that will soon fall into the 4+ million solar mass central black hole. The central part of this image is likely dark because little light-emitting gas is visible between us and the dark event horizon of the black hole. Continued EHT monitoring of this and M87's central black hole may yield new clues about the gravity of black holes and how infalling matter creates disks and jets<br><a href="https://pwg.gsfc.nasa.gov/Education/Imagnet.html" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">pwg.gsfc.nasa.gov/Education/Im</span><span class="invisible">agnet.html</span></a><br><a href="https://apod.nasa.gov/apod/ap140323.html" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">apod.nasa.gov/apod/ap140323.ht</span><span class="invisible">ml</span></a><br><a href="https://www.youtube.com/watch?v=60qnTvDbOZ0" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">youtube.com/watch?v=60qnTvDbOZ</span><span class="invisible">0</span></a><br><a href="https://eventhorizontelescope.org/science" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">eventhorizontelescope.org/scie</span><span class="invisible">nce</span></a><br><a href="https://eventhorizontelescope.org/blog/astronomers-unveil-strong-magnetic-fields-spiraling-edge-milky-way%E2%80%99s-central-black-hole" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">eventhorizontelescope.org/blog</span><span class="invisible">/astronomers-unveil-strong-magnetic-fields-spiraling-edge-milky-way%E2%80%99s-central-black-hole</span></a></p><p><a href="https://apod.nasa.gov/apod/ap240401.html" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">apod.nasa.gov/apod/ap240401.ht</span><span class="invisible">ml</span></a></p><p><a href="https://defcon.social/tags/space" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>space</span></a> <a href="https://defcon.social/tags/galaxy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>galaxy</span></a> <a href="https://defcon.social/tags/milkyway" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>milkyway</span></a> <a href="https://defcon.social/tags/astrophotography" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>astrophotography</span></a> <a href="https://defcon.social/tags/photography" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>photography</span></a> <a href="https://defcon.social/tags/science" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>science</span></a> <a href="https://defcon.social/tags/nature" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>nature</span></a> <a href="https://defcon.social/tags/EHT" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>EHT</span></a> <a href="https://defcon.social/tags/NASA" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>NASA</span></a></p>

Stars are observed to orbit a very massive and compact object there known as Sgr A* (say "sadge-ay-star"). But this just released radio image (inset) from planet Earth's Event Horizon Telescope is the first direct evidence of the Milky Way's central black hole. As predicted by Einstein's Theory of General Relativity, the four million solar mass black hole's strong gravity is bending light and creating a shadow-like dark central region surrounded by a bright ring-like structure. Supporting observations made by space-based telescopes and ground-based observatories provide a wider view of the galactic center's dynamic environment and an important context for the Event Horizon Telescope's black hole image. The main panel image shows the X-ray data from Chandra and infrared data from Hubble. While the main panel is about 7 light-years across, the Event Horizon Telescope inset image itself spans a mere 10 light-minutes at the center of our galaxy, some 27,000 light-years away. <br><a href="https://www.nasa.gov/image-article/sagittarius-nasa-telescopes-support-event-horizon-telescope-studying-milky-ways-black-hole/" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">nasa.gov/image-article/sagitta</span><span class="invisible">rius-nasa-telescopes-support-event-horizon-telescope-studying-milky-ways-black-hole/</span></a><br><a href="https://apod.nasa.gov/apod/ap070114.html" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">apod.nasa.gov/apod/ap070114.ht</span><span class="invisible">ml</span></a><br><a href="https://www6.slac.stanford.edu/research/physics-of-the-universe" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">www6.slac.stanford.edu/researc</span><span class="invisible">h/physics-of-the-universe</span></a><br><a href="https://eventhorizontelescope.org/blog/astronomers-reveal-first-image-black-hole-heart-our-galaxy" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">eventhorizontelescope.org/blog</span><span class="invisible">/astronomers-reveal-first-image-black-hole-heart-our-galaxy</span></a></p><p><a href="https://defcon.social/tags/space" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>space</span></a> <a href="https://defcon.social/tags/galaxy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>galaxy</span></a> <a href="https://defcon.social/tags/milkyway" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>milkyway</span></a> <a href="https://defcon.social/tags/astrophotography" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>astrophotography</span></a> <a href="https://defcon.social/tags/photography" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>photography</span></a> <a href="https://defcon.social/tags/science" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>science</span></a> <a href="https://defcon.social/tags/nature" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>nature</span></a> <a href="https://defcon.social/tags/EHT" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>EHT</span></a> <a href="https://defcon.social/tags/NASA" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>NASA</span></a></p>

In Jules Verne's science fiction classic, A Journey to the Center of the Earth, Professor Liedenbrock and his fellow explorers encounter many strange and exciting wonders. Astronomers already know of some of the bizarre objects that exist at our Galactic Center, including vast cosmic dust clouds, bright star clusters, swirling rings of gas, and even a supermassive black hole. Much of the Galactic Center is shielded from our view in visible light by the intervening dust and gas, but it can be explored using other forms of electromagnetic radiation. The featured video is actually a digital zoom into the Milky Way's center which starts by utilizing visible light images from the Digitized Sky Survey. As the movie proceeds, the light shown shifts to dust-penetrating infrared and highlights gas clouds that were recently discovered in 2013 to be falling toward the central black hole.<br><a href="https://apod.nasa.gov/apod/ap100831.html" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">apod.nasa.gov/apod/ap100831.ht</span><span class="invisible">ml</span></a><br><a href="https://en.wikipedia.org/wiki/Galactic_Center" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">en.wikipedia.org/wiki/Galactic</span><span class="invisible">_Center</span></a> <br><a href="https://apod.nasa.gov/apod/ap011229.html" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">apod.nasa.gov/apod/ap011229.ht</span><span class="invisible">ml</span></a><br><a href="https://en.wikipedia.org/wiki/Sagittarius_A" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">en.wikipedia.org/wiki/Sagittar</span><span class="invisible">ius_A</span></a>*</p><p><a href="https://apod.nasa.gov/apod/ap241124.html" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">apod.nasa.gov/apod/ap241124.ht</span><span class="invisible">ml</span></a></p><p><a href="https://defcon.social/tags/space" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>space</span></a> <a href="https://defcon.social/tags/galaxy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>galaxy</span></a> <a href="https://defcon.social/tags/milkyway" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>milkyway</span></a> <a href="https://defcon.social/tags/astrophotography" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>astrophotography</span></a> <a href="https://defcon.social/tags/photography" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>photography</span></a> <a href="https://defcon.social/tags/science" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>science</span></a> <a href="https://defcon.social/tags/nature" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>nature</span></a> <a href="https://defcon.social/tags/ESA" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>ESA</span></a> <a href="https://defcon.social/tags/GAIA" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>GAIA</span></a> <a href="https://defcon.social/tags/NASA" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>NASA</span></a></p>

grobi<p>TOPIC></p><p>Gaia Reconstructs a Top View of our Galaxy<br> * Illustration Credit: ESA, Gaia, DPAC, Stefan Payne-Wardenaar</p><p>Explanation:<br>What does our Milky Way Galaxy look like from the top? Because we are on the inside, humanity can’t get an actual picture. Recently, however, just such a map has been made using location data for over a billion stars from ESA’s Gaia mission. The resulting featured illustration shows that just like many other spiral galaxies, our Milky Way has distinct spiral arms. Our Sun and most of the bright stars we see at night are in just one arm: Orion. Gaia data bolsters previous indications that our Milky Way has more than two spiral arms. Our Galaxy's center sports a prominent bar. The colors of our Galaxy's thin disk derive mostly from dark dust, bright blue stars, and red emission nebula. Although data analysis is ongoing, Gaia was deactivated in March after a succession mission.<br><a href="https://science.nasa.gov/resource/the-milky-way-galaxy/" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">science.nasa.gov/resource/the-</span><span class="invisible">milky-way-galaxy/</span></a><br><a href="https://en.wikipedia.org/wiki/Orion_Arm" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">en.wikipedia.org/wiki/Orion_Ar</span><span class="invisible">m</span></a><br><a href="https://en.wikipedia.org/wiki/Milky_Way#Spiral_arms" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">en.wikipedia.org/wiki/Milky_Wa</span><span class="invisible">y#Spiral_arms</span></a><br><a href="https://apod.nasa.gov/apod/ap050825.html" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">apod.nasa.gov/apod/ap050825.ht</span><span class="invisible">ml</span></a></p><p><a href="https://apod.nasa.gov/apod/ap250513.html" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">apod.nasa.gov/apod/ap250513.ht</span><span class="invisible">ml</span></a></p><p><a href="https://defcon.social/tags/space" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>space</span></a> <a href="https://defcon.social/tags/galaxy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>galaxy</span></a> <a href="https://defcon.social/tags/milkyway" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>milkyway</span></a> <a href="https://defcon.social/tags/astrophotography" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>astrophotography</span></a> <a href="https://defcon.social/tags/photography" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>photography</span></a> <a href="https://defcon.social/tags/science" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>science</span></a> <a href="https://defcon.social/tags/nature" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>nature</span></a> <a href="https://defcon.social/tags/ESA" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>ESA</span></a> <a href="https://defcon.social/tags/GAIA" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>GAIA</span></a> <a href="https://defcon.social/tags/NASA" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>NASA</span></a></p>

grobi<p>Spirals On Edge<br> * Credit & Copyright: Robert Gendler</p><p>Explanation: <br>Spiral galaxies viewed face-on display a grand design, with graceful spiral arms traced by bright star clusters and glowing stellar nurseries. When seen edge-on, their appearance is very different but no less striking as their central regions bulge and dark cosmic dust lanes appear silhouetted against starlight from flattened galactic disks. This masterful mosaic of digital images shows nine prominent edge-on spirals arranged as follows: top; NGC2683, M104, NGC4565, middle; NGC891, NGC4631, NGC3628, and bottom; NGC5746, NGC5907, and NGC4217. Perhaps the best known of these is M104 (NGC4594) whose more descriptive moniker is the Sombrero Galaxy. Notably, the edge-on perspective of these galaxies allows a measurement of their galactic rotation speed using the Doppler effect. Plotting rotation speed versus distance from the center determines a galaxy's gravitational mass and historically led to premier evidence for mysterious Dark Matter.</p><p><a href="https://apod.nasa.gov/apod/ap010427.html" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">apod.nasa.gov/apod/ap010427.ht</span><span class="invisible">ml</span></a></p><p><a href="https://defcon.social/tags/space" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>space</span></a> <a href="https://defcon.social/tags/galaxy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>galaxy</span></a> <a href="https://defcon.social/tags/milkyway" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>milkyway</span></a> <a href="https://defcon.social/tags/astrophotography" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>astrophotography</span></a> <a href="https://defcon.social/tags/photography" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>photography</span></a> <a href="https://defcon.social/tags/science" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>science</span></a> <a href="https://defcon.social/tags/nature" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>nature</span></a> <a href="https://defcon.social/tags/NASA" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>NASA</span></a></p>

Michael KingThe Milky Way rising over the Victorian coast at Flinders Blowhole last Friday night. It was very peaceful watching the moon set and the stars move, with the sounds of the waves below. The orange glow of Aurora Australis wasn't visible to the naked eye, but clear in the viewfinder.

SpikyynOn May 4th from last year, we had a scheduled power outage that went from 12am to 8am. That night, I woke up hearing my dad failing to start the generator in the garage just to get our electric fans and chargers work again in our bedroom.<br>
<br>
Me and my parents decided to walk to our terrace with my tripod in upstairs, checking to see if the sky is clear so I can do astrophoto stuff that time, while my dad sleeps there for a cool, fresh air. To my surprise, there were no lights around our street so some of the stars and satellites we haven't seen before are now visible than usual (except we had a bright solar light that lighted our terrace's door, aswell as the moon being visible in its Waning Crescent phase but they don't affect my astrophotography by much). Also, bortle scale here was around 2-3 scale that night (normally it is around 5 with power on).<br>
<br>
And then me and my mom noticed this dark grey-ish cloud in the sky above our heads, next to the moving clouds being in the way. It was really barely visible to our eyes. I thought I saw a Milky Way for the first time... but it actually is after I opened the Stellarium app on my phone and pointed at it!<br>
<br>
Got me excited. So I mounted my phone to my tripod and took several pics of the galactic core before we went back to sleep at 5am, waiting for the electricity to be back. I was amazed by my wonderful photos of it from my phone after checking them :D<br>
<br>
I only picked the first and the last on this post because they are the best. For now, these are also my last Milky Way pics I have only seen clearly like that from it. <a href="https://pixelfed.social/discover/tags/ThrowbackThursday?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#ThrowbackThursday</a><br>
