catherinerhyde<p>The bright star here is Sadr. The Sadr region is home to a massive field of nebulosity often called the Butterfly.

grobi<p>Tour: <br>A New Panorama of Our Galactic Center</p><p>Credit: <br>NASA/CXC/A. Hobart</p><p>A new panorama from NASA's Chandra X-ray Observatory and the MeerKAT radio telescope provides a stunning view of the center of our Milky Way galaxy. It also reveals threads of superheated gas and magnetic fields, which are weaving a tapestry of energy near the supermassive black hole that resides there.</p><p>Over the course of its mission, Chandra has taken many observations of the Galactic Center. This latest expands Chandra's high-energy view farther above and below the plane of the galaxy — that is, the disk where most of the galaxy's stars reside — than previous imaging campaigns. In the image, we see X-rays with different energies from Chandra in different colors. These have been combined with radio data from MeerKAT, a radio telescope in South Africa.</p><p>The result is intricate to the eye and also contains a wealth of scientific information to explore. For example, researchers identified long and narrow bands of X-rays that they call "threads". These features are bound together by thin strips of magnetic fields. One of these threads points perpendicular to the plane of the galaxy and is about 20 light-years long but only one-hundredth that size in width. (That's about five times the distance between the Sun and the nearest star.) These threads may have formed when magnetic fields aligned in different directions, collided, and became twisted around each other in a process called magnetic reconnection. This is similar to the phenomenon that drives energetic particles away from the Sun and is responsible for the space weather that sometimes affects Earth.</p><p>A detailed study of these threads teaches us more about the galactic space weather astronomers have witnessed throughout the region. <br>[...] <br>More information in ALT-Text</p><p><a href="https://chandra.harvard.edu/photo/2021/gcenter/animations.html" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">chandra.harvard.edu/photo/2021</span><span class="invisible">/gcenter/animations.html</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/galaxy" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>galaxy</span></a> <a href="https://defcon.social/tags/milkyway" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>milkyway</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/physics" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>physics</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/EHT" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>EHT</span></a> <a href="https://defcon.social/tags/CHANDRA" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>CHANDRA</span></a> <a href="https://defcon.social/tags/NASA" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>NASA</span></a> <a href="https://defcon.social/tags/education" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>education</span></a></p>

To help find out, a newly detailed panorama has been composed that explores regions just above and below the galactic plane in radio and X-ray light. X-ray light taken by the orbiting Chandra Observatory is shown in orange (hot), green (hotter), and purple (hottest) and superposed with a highly detailed image in radio waves, shown in gray, acquired by the MeerKAT array. Interactions are numerous and complex. Galactic beasts such as expanding supernova remnants, hot winds from newly formed stars, unusually strong and colliding magnetic fields, and a central supermassive black hole are all battling in a space only 1000 light years across. Thin bright stripes appear to result from twisting and newly connecting magnetic fields in colliding regions, creating an energetic type of inner galactic space weather with similarities to that created by our Sun. Continued observations and study hold promise to not only shed more light on the history and evolution of our own galaxy -- but all galaxies. <br><a href="https://arxiv.org/abs/2010.02932" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="">arxiv.org/abs/2010.02932</span><span class="invisible"></span></a></p><p><a href="https://apod.nasa.gov/apod/ap210602.html" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">apod.nasa.gov/apod/ap210602.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/galaxy" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>galaxy</span></a> <a href="https://defcon.social/tags/milkyway" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>milkyway</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/physics" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>physics</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/EHT" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>EHT</span></a> <a href="https://defcon.social/tags/CHANDRA" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>CHANDRA</span></a> <a href="https://defcon.social/tags/NASA" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>NASA</span></a></p>
