Cataloged as NGC 7635, it is also known simply as The Bubble Nebula. Although it looks delicate, the 7 light-year diameter bubble offers evidence of violent processes at work. Above and left of the Bubble's center is a hot, O-type star, several hundred thousand times more luminous and some 45 times more massive than the Sun. A fierce stellar wind and intense radiation from that star has blasted out the structure of glowing gas against denser material in a surrounding molecular cloud. The intriguing Bubble Nebula and associated cloud complex lie a mere 7,100 light-years away toward the boastful constellation Cassiopeia. This sharp, tantalizing view of the cosmic bubble is a composite of Hubble Space Telescope image data from 2016, reprocessed to present the nebula's intense narrowband emission in an approximate true color scheme.<a href="https://apod.nasa.gov/apod/ap180419.html" rel="nofollow noopener" translate="no" target="_blank">https://apod.nasa.gov/apod/ap180419.html</a><a href="https://defcon.social/tags/space" class="mention hashtag" rel="nofollow noopener" target="_blank">#space</a> <a href="https://defcon.social/tags/nova" class="mention hashtag" rel="nofollow noopener" target="_blank">#nova</a> <a href="https://defcon.social/tags/supernova" class="mention hashtag" rel="nofollow noopener" target="_blank">#supernova</a> <a href="https://defcon.social/tags/astrophotography" class="mention hashtag" rel="nofollow noopener" target="_blank">#astrophotography</a> <a href="https://defcon.social/tags/photography" class="mention hashtag" rel="nofollow noopener" target="_blank">#photography</a> <a href="https://defcon.social/tags/science" class="mention hashtag" rel="nofollow noopener" target="_blank">#science</a> <a href="https://defcon.social/tags/physics" class="mention hashtag" rel="nofollow noopener" target="_blank">#physics</a> <a href="https://defcon.social/tags/astronomy" class="mention hashtag" rel="nofollow noopener" target="_blank">#astronomy</a> <a href="https://defcon.social/tags/nature" class="mention hashtag" rel="nofollow noopener" target="_blank">#nature</a> <a href="https://defcon.social/tags/NASA" class="mention hashtag" rel="nofollow noopener" target="_blank">#NASA</a> <a href="https://defcon.social/tags/ESA" class="mention hashtag" rel="nofollow noopener" target="_blank">#ESA</a>

Rare, massive Wolf-Rayet stars are so tumultuous and hot that they are slowly disintegrating right before our telescopes. Glowing gas globs each typically over 30 times more massive than the Earth are being expelled by violent stellar winds. Wolf-Rayet star WR 124, visible near the featured image center, is thus creating the surrounding nebula known as M1-67, which spans six light years across. Details of why this star has been slowly blowing itself apart over the past 20,000 years remains a topic of research. WR 124 lies 15,000 light-years away towards the constellation of the Arrow (Sagitta). The fate of any given Wolf-Rayet star likely depends on how massive it is, but many are thought to end their lives with spectacular explosions such as supernovas or gamma-ray bursts. <a href="https://apod.nasa.gov/apod/ap250203.html" rel="nofollow noopener" translate="no" target="_blank">https://apod.nasa.gov/apod/ap250203.html</a><a href="https://defcon.social/tags/space" class="mention hashtag" rel="nofollow noopener" target="_blank">#space</a> <a href="https://defcon.social/tags/nova" class="mention hashtag" rel="nofollow noopener" target="_blank">#nova</a> <a href="https://defcon.social/tags/supernova" class="mention hashtag" rel="nofollow noopener" target="_blank">#supernova</a> <a href="https://defcon.social/tags/astrophotography" class="mention hashtag" rel="nofollow noopener" target="_blank">#astrophotography</a> <a href="https://defcon.social/tags/photography" class="mention hashtag" rel="nofollow noopener" target="_blank">#photography</a> <a href="https://defcon.social/tags/science" class="mention hashtag" rel="nofollow noopener" target="_blank">#science</a> <a href="https://defcon.social/tags/physics" class="mention hashtag" rel="nofollow noopener" target="_blank">#physics</a> <a href="https://defcon.social/tags/astronomy" class="mention hashtag" rel="nofollow noopener" target="_blank">#astronomy</a> <a href="https://defcon.social/tags/nature" class="mention hashtag" rel="nofollow noopener" target="_blank">#nature</a> <a href="https://defcon.social/tags/NASA" class="mention hashtag" rel="nofollow noopener" target="_blank">#NASA</a> <a href="https://defcon.social/tags/ESA" class="mention hashtag" rel="nofollow noopener" target="_blank">#ESA</a>

grobiType Ia supernovaFrom Wikipedia, the free encyclopediaAt the core of a planetary nebula, Henize 2-428, two white dwarf stars slightly under one solar mass each are expected to merge and create a Type Ia supernova destroying both in about 700 million years (artist's impression).A Type Ia supernova (read: "type one-A") is a type of supernova that occurs in binary systems (two stars orbiting one another) in which one of the stars is a white dwarf. The other star can be anything from a giant star to an even smaller white dwarf.Physically, carbon–oxygen white dwarfs with a low rate of rotation are limited to below 1.44 solar masses (M☉). Beyond this "critical mass", they reignite and in some cases trigger a supernova explosion; this critical mass is often referred to as the Chandrasekhar mass, but is marginally different from the absolute Chandrasekhar limit, where electron degeneracy pressure is unable to prevent catastrophic collapse. If a white dwarf gradually accretes mass from a binary companion, or merges with a second white dwarf, the general hypothesis is that a white dwarf's core will reach the ignition temperature for carbon fusion as it approaches the Chandrasekhar mass. Within a few seconds of initiation of nuclear fusion, a substantial fraction of the matter in the white dwarf undergoes a runaway reaction, releasing enough energy (1×1044 J) to unbind the star in a supernova explosion.The Type Ia category of supernova produces a fairly consistent peak luminosity because of the fixed critical mass at which a white dwarf will explode. Their consistent peak luminosity allows these explosions to be used as standard candles to measure the distance to their host galaxies: the visual magnitude of a type Ia supernova, as observed from Earth, indicates its distance from Earth.

grobi10 Years ago ..2016 February 9The Rise and Fall of Supernova 2015F * Video Credit & Copyright: Changsu Choi & Myungshin Im (Seoul National University) <a href="https://physics.snu.ac.kr/en" rel="nofollow noopener" translate="no" target="_blank">https://physics.snu.ac.kr/en</a>Explanation: Sit back and watch a star explode. The actual supernova occurred back when dinosaurs roamed the Earth, but images of the spectacular event began arriving last year. Supernova 2015F was discovered in nearby spiral galaxy NGC 2442 by Berto Monard in 2015 March and was unusually bright -- enough to be seen with only a small telescope. The pattern of brightness variation indicated a Type Ia supernova -- a type of stellar explosion that results when an Earth-size white dwarf gains so much mass that its core crosses the threshold of nuclear fusion, possibly caused by a lower mass white-dwarf companion spiraling into it. Finding and tracking Type Ia supernovae are particularly important because their intrinsic brightness can be calibrated, making their apparent brightness a good measure of their distance -- and hence useful toward calibrating the distance scale of the entire universe. The featured video tracked the stellar disruption from before explosion images arrived, as it brightened, and for several months as the fission-powered supernova glow faded. The remnants of SN2015F are now too dim to see without a large telescope. Just yesterday, however, the night sky lit up once again, this time with an even brighter supernova in an even closer galaxy: Centaurus A.<a href="https://apod.nasa.gov/apod/random_apod.html" rel="nofollow noopener" translate="no" target="_blank">https://apod.nasa.gov/apod/random_apod.html</a><a href="https://defcon.social/tags/space" class="mention hashtag" rel="nofollow noopener" target="_blank">#space</a> <a href="https://defcon.social/tags/nova" class="mention hashtag" rel="nofollow noopener" target="_blank">#nova</a> <a href="https://defcon.social/tags/supernova" class="mention hashtag" rel="nofollow noopener" target="_blank">#supernova</a> <a href="https://defcon.social/tags/astrophotography" class="mention hashtag" rel="nofollow noopener" target="_blank">#astrophotography</a> <a href="https://defcon.social/tags/photography" class="mention hashtag" rel="nofollow noopener" target="_blank">#photography</a> <a href="https://defcon.social/tags/science" class="mention hashtag" rel="nofollow noopener" target="_blank">#science</a> <a href="https://defcon.social/tags/physics" class="mention hashtag" rel="nofollow noopener" target="_blank">#physics</a> <a href="https://defcon.social/tags/astronomy" class="mention hashtag" rel="nofollow noopener" target="_blank">#astronomy</a> <a href="https://defcon.social/tags/nature" class="mention hashtag" rel="nofollow noopener" target="_blank">#nature</a> <a href="https://defcon.social/tags/NASA" class="mention hashtag" rel="nofollow noopener" target="_blank">#NASA</a> <a href="https://defcon.social/tags/ESA" class="mention hashtag" rel="nofollow noopener" target="_blank">#ESA</a>
