The radio waves fit no currently understood pattern of variable radio source and could suggest a new class of stellar object.<\/p>\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 Ziteng Wang, lead author of the new study and a PhD student in the School of Physics at the University of Sydney.<\/p>\n<p><span class=\"embed-youtube\" style=\"text-align:center; display: block;\"><iframe loading=\"lazy\" class=\"youtube-player\" width=\"625\" height=\"352\" src=\"https:\/\/www.youtube.com\/embed\/J_eGd9Ps9fE?version=3&#038;rel=1&#038;showsearch=0&#038;showinfo=1&#038;iv_load_policy=1&#038;fs=1&#038;hl=en-US&#038;autohide=2&#038;wmode=transparent\" allowfullscreen=\"true\" style=\"border:0;\" sandbox=\"allow-scripts allow-same-origin allow-popups allow-presentation allow-popups-to-escape-sandbox\"><\/iframe><\/span><\/p>\n<p>\u201cThe brightness of the object also varies dramatically, by a factor of 100, and the signal switches on and off apparently at random. We\u2019ve never seen anything like it.\u201d<\/p>\n<p>Many types of star emit variable light across the electromagnetic spectrum. With tremendous advances in radio astronomy, the study of variable or transient objects in radio waves is a huge field of study helping us to reveal the secrets of the Universe. Pulsars, supernovae, flaring stars and fast radio bursts are all types of astronomical objects whose brightness varies.<\/p>\n<p>\u201cAt first we thought it could be a pulsar \u2013 a very dense type of spinning dead star \u2013 or else a type of star that emits huge solar flares. But the signals from this new source don\u2019t match what we expect from these types of celestial objects,\u201d Mr Wang said.<\/p>\n<p>The discovery of the object has been published today in the <a href=\"https:\/\/iopscience.iop.org\/journal\/0004-637X\" target=\"_blank\" rel=\"noopener\">Astrophysical Journal<\/a>.<\/p>\n<p style=\"text-align: center;\"><a href=\"https:\/\/www.sydney.edu.au\/news-opinion\/news\/2021\/10\/12\/strange-radiowaves-galactic-centre-askap-j173608-2-321635.html\" target=\"_blank\" rel=\"noopener\">Click here to read the full article at the University of Sydney.<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>(Source: University of Sydney) Strange radio waves emerge from direction of the galactic centre A signal from deep in the Milky Way is tantalising scientists International student Ziteng Wang detected unusual signals from deep in the heart of the Milky Way using CSIRO&#8217;s ASKAP radio telescope.
