The unique way in which the polarization of the waves rotates, as well as the variation in brightness, doesn\u2019t closely match what the astronomers expect of other known celestial objects.<\/p>\n<p><span id=\"more-22298\"><\/span><\/p>\n<p class=\"wp-block-paragraph\">Published today in The Astrophysical Journal, the Astronomers have named the object responsible ASKAP J173608.2-321635, after its coordinates.<\/p>\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>\u201cThis object was unique in that it started out invisible, became bright, faded away, and then reappeared. This behaviour was extraordinary.\u201d<\/p>\n<p><cite>Professor Tara Murphy<\/cite><\/p><\/blockquote>\n<p class=\"wp-block-paragraph\">The international team of scientists behind the paper first discovered the object using the Commonwealth Scientific and Industrial Research Organizations (CSIRO\u2019s) Australian Square Kilometer Array Pathfinder (ASKAP) telescope. The telescope array (which will be fully operational next year) makes use of 36 dish antennas 12 meters in diameter spread across a large area to increase the imaging capabilities.<\/p>\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>\u201cThe strangest property of this new signal is that it is has a very high polarisation. This means its light oscillates in only one direction, but that direction rotates with time,\u201d said&nbsp;Ziteng Wang, lead author of the new study.<\/p>\n<\/blockquote>\n<p class=\"wp-block-paragraph\">Over the course of nine months in 2020, the teams observed six radio signals from the object, but were unable locate the source object in visible light.<\/p>\n<p>\t<span class=\"outbrain-ad-label\"><\/span><\/p>\n<p>\t\t<script type=\"text\/plain\">\n\t\t\twindow.adSlotsConfig = window.adSlotsConfig || [];<\/p>\n<p>\t\t\tadSlotsConfig.push( {\n\t\t\t\tslotID: '\/1049447\/Outbrain',\n\t\t\t\tslotName: 'div-gpt-ad-outbrain-ad-22298',\n\t\t\t\tsizes: [300, 250],\n\t\t\t\tslotPosition: 'mid_article'\n\t\t\t} );\n\t\t<\/script><\/p>\n<p class=\"wp-block-paragraph\">The intermittent nature of the signal led the team to attempt to locate the object with a more sensitive telescope. The team used the MeerKAT radio telescope (the precursor to the Square Kilometer Array). Using the different equipment they located the single once again, but it was still intermittent,<\/p>\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>Professor David Kaplan&nbsp;from the University of Wisconsin-Milwaukee, said, \u201cThe information we do have has some parallels with another emerging class of mysterious objects known as Galactic Centre Radio Transients [GCRT], including one dubbed the \u2018cosmic burper.\u2019\u201d<\/p>\n<\/blockquote>\n<p class=\"wp-block-paragraph\">But even these GCRTs are not well understood by scientists.<\/p>\n<p class=\"wp-block-paragraph\">For now, this is another object in the space that is not yet understood. <\/p>\n<p class=\"wp-block-paragraph\">The team notes in the paper that with how little time these emissions were detected, and the limited nature of sampling, suggests there could be other objects like this one in the field that simply haven\u2019t been observed yet.<\/p>\n<p class=\"wp-block-paragraph\">Hopefully future telescopes, such as the intercontinental Square Kilometer Array, will come online and provide additional more regular data to help understand this newly discovered object.<\/p>\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>\u201cWe expect the power of this telescope will help us solve mysteries such as this latest discovery, but it will also open vast new swathes of the cosmos to exploration in the radio spectrum.\u201d<\/p>\n<p><cite>Professor Murphy<\/cite><\/p><\/blockquote>\n<h2 class=\"wp-block-heading\" id=\"h-want-to-help-support-space-explored\">Want to help support Space Explored?<\/h2>\n<p class=\"wp-block-paragraph\">Follow Derek on Twitter or Instagram.<\/p>\n<p class=\"wp-block-paragraph\">Shop on&nbsp;Amazon or directly support Derek by becoming a member of their&nbsp;Patreon.<\/p>\n<h3 class=\"wp-block-heading\" id=\"enjoy-reading-space-explored\">Enjoy reading Space Explored?<\/h3>\n<p class=\"wp-block-paragraph\">Help others find us by following on <strong>Apple News<\/strong> and <strong>Google News<\/strong>.
