Benjamin Carr, Ph.D. 👨🏻‍💻🧬<p>Scientists uncovered a <a href="https://hachyderm.io/tags/binarystar" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>binarystar</span></a> system close to <a href="https://hachyderm.io/tags/blackhole" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>blackhole</span></a> near center of <a href="https://hachyderm.io/tags/MilkyWay" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>MilkyWay</span></a>, confirming a hypothesis made by happenstance nearly a century ago, according to a paper published in Nature Communications. Scientists previously predicted the existence of a binary <a href="https://hachyderm.io/tags/star" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>star</span></a> system -- one in which two stars are gravitationally bound to one another around a common center of gravity -- in the vicinity of the black hole at the center of the galaxy, called <a href="https://hachyderm.io/tags/SagittariusA" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>SagittariusA</span></a>*. <br><a href="https://abcnews.go.com/Technology/binary-star-system-found-milky-way-black-hole/story?id=116763825" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">abcnews.go.com/Technology/bina</span><span class="invisible">ry-star-system-found-milky-way-black-hole/story?id=116763825</span></a></p>

1 Dipl. fckng Ing.*<p>"However, that assumes the long pulsation cycle is internal. If it’s actually due to a second star, then Betelgeuse is likely still fusing helium in its core, which means it has a lot longer left to go before it detonates, over a hundred thousand years. If you’re waiting for it to explode, and this second star turns out to be real, well then you’d better pack a lunch. It’ll be a while."</p><p>😭 🥪 </p><p><a href="https://badastronomy.beehiiv.com/p/is-betelgeuse-binary" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">badastronomy.beehiiv.com/p/is-</span><span class="invisible">betelgeuse-binary</span></a></p><p><a href="https://mastodon.social/tags/alphaorionis" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>alphaorionis</span></a> <a href="https://mastodon.social/tags/betelgeuse" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>betelgeuse</span></a> <a href="https://mastodon.social/tags/binarystar" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>binarystar</span></a> <a href="https://mastodon.social/tags/supernova" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>supernova</span></a> <a href="https://mastodon.social/tags/astronomy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>astronomy</span></a></p>

The new planet was discovered using radial-velocity data , it is a 65.2 M⊕ <a href="https://scicomm.xyz/tags/circumbinary" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>circumbinary</span></a> planet with a period of 215.5 days. This is the first detection of a circumbinary planet using radial-velocity observations alone, and makes it only the second confirmed multiplanet circumbinary system to date: <a href="https://arxiv.org/abs/2301.10794" rel="nofollow noopener noreferrer" target="_blank"><span class="invisible">https://</span><span class="">arxiv.org/abs/2301.10794</span><span class="invisible"></span></a></p>
