XF9Meet Bode's (M81) and the Cigar galaxy (M82). The larger M81 passed the smaller M82 quite some million years ago, leaving it deformed. This also causes the dust and gases inside to collide much frequently, making this a starburst region where stars are born at a much higher rate than usual. This also causes the ejection of the bright red hydrogen. For this image I took ~14 hours of RGB data and another 10 hours of just the hydrogen. I still struggle a bit with star shapes in the corners, but nothing BlurX can't fix.

grobiSwirling Magnetic Field around Our Galaxy's Central Black Hole * Image Credit: EHT Collaboration <a href="https://eventhorizontelescope.org/organization" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://eventhorizontelescope.org/organization</a>Explanation: What's happening to the big black hole in the center of our galaxy? 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 <a href="https://pwg.gsfc.nasa.gov/Education/Imagnet.html" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://pwg.gsfc.nasa.gov/Education/Imagnet.html</a> <a href="https://apod.nasa.gov/apod/ap140323.html" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://apod.nasa.gov/apod/ap140323.html</a> <a href="https://www.youtube.com/watch?v=60qnTvDbOZ0" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://www.youtube.com/watch?v=60qnTvDbOZ0</a> <a href="https://eventhorizontelescope.org/science" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://eventhorizontelescope.org/science</a> <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">https://eventhorizontelescope.org/blog/astronomers-unveil-strong-magnetic-fields-spiraling-edge-milky-way%E2%80%99s-central-black-hole</a><a href="https://apod.nasa.gov/apod/ap240401.html" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://apod.nasa.gov/apod/ap240401.html</a><a href="https://defcon.social/tags/space" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#space</a> <a href="https://defcon.social/tags/galaxy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#galaxy</a> <a href="https://defcon.social/tags/milkyway" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#milkyway</a> <a href="https://defcon.social/tags/astrophotography" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#astrophotography</a> <a href="https://defcon.social/tags/photography" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#photography</a> <a href="https://defcon.social/tags/science" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#science</a> <a href="https://defcon.social/tags/nature" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#nature</a> <a href="https://defcon.social/tags/EHT" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#EHT</a> <a href="https://defcon.social/tags/NASA" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#NASA</a>

grobiThe Milky Way's Black Hole * Image Credit: X-ray - NASA/CXC/SAO, IR - NASA/HST/STScI; Inset: Radio - Event Horizon Telescope Collaboration <a href="https://eventhorizontelescope.org/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://eventhorizontelescope.org/</a> <a href="https://www.stsci.edu/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://www.stsci.edu/</a> <a href="https://chandra.harvard.edu/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://chandra.harvard.edu/</a>Explanation: There's a black hole at the center of the Milky Way. 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. <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">https://www.nasa.gov/image-article/sagittarius-nasa-telescopes-support-event-horizon-telescope-studying-milky-ways-black-hole/</a> <a href="https://apod.nasa.gov/apod/ap070114.html" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://apod.nasa.gov/apod/ap070114.html</a> <a href="https://www6.slac.stanford.edu/research/physics-of-the-universe" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://www6.slac.stanford.edu/research/physics-of-the-universe</a> <a href="https://eventhorizontelescope.org/blog/astronomers-reveal-first-image-black-hole-heart-our-galaxy" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://eventhorizontelescope.org/blog/astronomers-reveal-first-image-black-hole-heart-our-galaxy</a><a href="https://defcon.social/tags/space" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#space</a> <a href="https://defcon.social/tags/galaxy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#galaxy</a> <a href="https://defcon.social/tags/milkyway" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#milkyway</a> <a href="https://defcon.social/tags/astrophotography" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#astrophotography</a> <a href="https://defcon.social/tags/photography" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#photography</a> <a href="https://defcon.social/tags/science" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#science</a> <a href="https://defcon.social/tags/nature" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#nature</a> <a href="https://defcon.social/tags/EHT" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#EHT</a> <a href="https://defcon.social/tags/NASA" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#NASA</a>

grobiGaia Reconstructs a Top View of our Galaxy * Illustration Credit: ESA, Gaia, DPAC, Stefan Payne-WardenaarExplanation: 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. <a href="https://science.nasa.gov/resource/the-milky-way-galaxy/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://science.nasa.gov/resource/the-milky-way-galaxy/</a> <a href="https://en.wikipedia.org/wiki/Orion_Arm" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://en.wikipedia.org/wiki/Orion_Arm</a> <a href="https://en.wikipedia.org/wiki/Milky_Way#Spiral_arms" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://en.wikipedia.org/wiki/Milky_Way#Spiral_arms</a> <a href="https://apod.nasa.gov/apod/ap050825.html" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://apod.nasa.gov/apod/ap050825.html</a><a href="https://apod.nasa.gov/apod/ap250513.html" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://apod.nasa.gov/apod/ap250513.html</a><a href="https://defcon.social/tags/space" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#space</a> <a href="https://defcon.social/tags/galaxy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#galaxy</a> <a href="https://defcon.social/tags/milkyway" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#milkyway</a> <a href="https://defcon.social/tags/astrophotography" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#astrophotography</a> <a href="https://defcon.social/tags/photography" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#photography</a> <a href="https://defcon.social/tags/science" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#science</a> <a href="https://defcon.social/tags/nature" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#nature</a> <a href="https://defcon.social/tags/ESA" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ESA</a> <a href="https://defcon.social/tags/GAIA" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#GAIA</a> <a href="https://defcon.social/tags/NASA" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#NASA</a>
