Recently, scientists noticed that these bodies were behaving somewhat strangely. They decided to investigate further and discovered that there are some changes happening to them that could cause an event never seen before in the entire universe.<\/span><\/p>\n<h2>What two stars are these, and where are they?<\/h2>\n<p><span style=\"font-weight: 400;\">These stars are present in the<\/span><b> constellation T Coronae Borealis<\/b><span style=\"font-weight: 400;\">, which is about 3 thousand light-years from Earth. And the most curious thing is that this constellation has been present in our analyses here on Earth for a long time. It has a very unique history of activity, even though until 2016 everything was calm \u2013 apparently, too calm.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Since 2016, astronomers have begun to notice that the constellation is changing drastically, because they noticed that it was getting brighter, in addition to acquiring an unusual bluish coloration. This behavior even reminded them of something similar that happened in 1946, when there was an explosion \u2013 yes, we may have to prepare ourselves. And which two stars make up this constellation? We are talking about:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">A <\/span><b>red giant<\/b>,\u00a0<span style=\"font-weight: 400;\">which is an expanded and ageing star;<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">And a <\/span><b>white dwarf<\/b><span style=\"font-weight: 400;\">, which is nothing more than the hot and dense core remaining from a star like the Sun.<\/span><\/li>\n<\/ul>\n<h2>What are experts expecting from this strange behavior?<\/h2>\n<p><span style=\"font-weight: 400;\">After analyzing the constellation with the Fermi space telescope, scientists were able to reveal that it appears that T Coronae Borealis is about to undergo a rather rare astronomical phenomenon called a <\/span><b>recurrent nova<\/b><span style=\"font-weight: 400;\">. Okay, so what does that mean? Well, it will become a temporary new star that will be visible to the naked eye in the night sky.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">And of course, this will happen through an explosion, it couldn&#8217;t be any other way, right? This explosion is thermonuclear and occurs when the matter stolen from the red giant accumulates on the super hot surface of the white dwarf, and this causes an explosive reaction that can increase the brightness of the system by up to 1,585 times (recently another star caught attention by <a href=\"https:\/\/www.ecoticias.com\/en\/neutron-star-mass-distribution-research\/13416\/\">revealing something inside it that no one expected<\/a>)<\/span><span style=\"font-weight: 400;\">.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This phenomenon has happened before, but it was a long time ago in the years 1787, 1866, and 1946, with a possible historical record in 1217. You can see that<strong> each cycle takes approximately 80 years to complete<\/strong>, meaning we&#8217;re very close to this happening again, even if we can&#8217;t yet give an exact date. Astronomer Sumner Starrfield and astrophysicist Javier Armentia even give us a heads-up:<\/span><\/p>\n<blockquote><p><i><span style=\"font-weight: 400;\">\u201cThere is no way to predict exactly when it will explode. Our estimates of when it will happen soon are based on observations of its behavior just before the explosion 80 years ago. Its current behavior gives us clues, but it cannot be determined\u201d<\/span><\/i><span style=\"font-weight: 400;\">.<\/span><\/p><\/blockquote>\n<h2>The unique event that stars can cause<\/h2>\n<p><span style=\"font-weight: 400;\">In addition to this explosion being fundamental for academic life itself \u2013 after all, all phenomena are observed closely \u2013 it will be sensational for the constellation T Coronae Borealis to become visible to the naked eye as a temporarily bright star in the northern hemisphere sky.\u00a0<\/span><\/p>\n<blockquote><p><i><span style=\"font-weight: 400;\">\u201cThere are some recurrent novae with very short cycles, but we don&#8217;t typically see a repeating explosion in a human lifetime.\u201d &#8211; Rebekah Hounsell<\/span><\/i><\/p><\/blockquote>\n<p><span style=\"font-weight: 400;\">Astronomers believe that\u00a0<\/span><span style=\"margin: 0px; padding: 0px;\">it can\u00a0<strong>shine<\/strong><\/span><b>\u00a0for about a whole week<\/b><span style=\"font-weight: 400;\">, which allows us to appreciate it as much as we want, in addition to being a great time for professionals to do their analyses. Even if this phenomenon does not happen for now, it is very important to have this prediction for modern astronomy.
