grobi<p>2025 July 31</p><p>Supernova 2025rbs in NGC 7331<br> * Image Credit: Ben Godson (University of Warwick)<br><a href="https://warwick.ac.uk/fac/sci/physics/research/astro/people/bengodson/" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">warwick.ac.uk/fac/sci/physics/</span><span class="invisible">research/astro/people/bengodson/</span></a></p><p>Explanation: <br>A long time ago in a galaxy 50 million light-years away, a star exploded. Light from that supernova was first detected by telescopes on planet Earth on July 14th though, and the extragalactic transient is now known to astronomers as supernova 2025rbs. Presently the brightest supernova in planet Earth's sky, 2025rbs is a Type Ia supernova, likely caused by the thermonuclear detonation of a white dwarf star that accreted material from a companion in a binary star system. Type Ia supernovae are used as standard candles to establish the distance scale of the universe. The host galaxy of 2025rbs is NGC 7331. Itself a bright spiral galaxy in the northern constellation Pegasus, NGC 7331 is often touted as an analog to our own Milky Way. <br><a href="https://goto-observatory.org/bright-supernova-2025rbs-discovered-by-goto/" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">goto-observatory.org/bright-su</span><span class="invisible">pernova-2025rbs-discovered-by-goto/</span></a><br><a href="https://www.wis-tns.org/object/2025rbs" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="">wis-tns.org/object/2025rbs</span><span class="invisible"></span></a><br><a href="https://rochesterastronomy.org/supernova.html" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">rochesterastronomy.org/superno</span><span class="invisible">va.html</span></a></p><p><a href="https://apod.nasa.gov/apod/ap250731.html" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">apod.nasa.gov/apod/ap250731.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/supernova" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>supernova</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/NASA" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>NASA</span></a> <a href="https://defcon.social/tags/ESA" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ESA</span></a> <a href="https://defcon.social/tags/education" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>education</span></a></p>

cafuego 🔭🤦🏼‍♂️<p>Lights of Downtown</p><p>After the very very pretty crescent Moon had set last night, I was convinced to go out and make use of the clear sky and the center of our galaxy being directly overhead.</p><p>I got a lot of nice and sharp photos, but decided to also do a defocused one, so I could catch the colours of the stars. (When an image is in focus, generally the light from a tiny star saturates all the sensor pixels it falls on and you end up with them looking white)</p><p>The bright orange star at lower left is Antares, and you can just make out the shape of Scorpius. The orange patch above center is Baades Window, the stars behind the dust in the spiral arm and the bright patch just right of the middle is the Sagittarius Star Cloud.</p><p>This is a single 30 second exposure with a Nikon D750 and Sigma Art 35mm f/1.4 lens at f/2.5.</p><p><a href="https://misanthrope.social/tags/space" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>space</span></a> <a href="https://misanthrope.social/tags/astrophotography" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>astrophotography</span></a> <a href="https://misanthrope.social/tags/astrodon" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>astrodon</span></a></p>
