But researchers at the University of Sydney recently detected radio signals that do not match any known types. The waves, originating near the center of the <keyword id="12323604" type="UNKNOWN" weightage="60" keywordseo="milky-way" source="Orion">Milky Way</keyword>, don't seem to be coming from any kind of star, planet, or space rock that scientists have seen before.</p><p>Even stranger, the strength of this signal has waxed and waned dramatically over just a few months. Most objects in the <keyword id="11921801" type="UNKNOWN" weightage="60" keywordseo="galaxy" source="Orion">galaxy</keyword>, by contrast, don't change much year to year - and therefore nor do their radio waves.</p><p>"The signal switches on and off apparently at random. We've never seen anything like it," Ziteng Wang, the lead author of the new study and a PhD student in physics at the University of Sydney, said in a <a href="https://www.sydney.edu.au/news-opinion/news/2021/10/12/strange-radiowaves-galactic-centre-askap-j173608-2-321635.html">press release</a>.</p><p>A paper describing the discovery was <a href="https://iopscience.iop.org/article/10.3847/1538-4357/ac2360">published</a> Tuesday in The Astrophysical Journals. In it, Wang and his coauthors concluded that the mysterious source of this radio signal "may represent part of a new class of objects."</p><h2>The radio signal disappeared for months, reemerged suddenly, then vanished again</h2><div type="image" title="radio wave animation shows distant bright light sending intermittent spirals towards earth" height="640" width="640" msid="87060746" hostid="261"></div><p>Whatever the mysterious object is that's responsible for this phenomenon, it was emitting strong radio waves through most of 2020. The researchers detected six signals over nine months, using the ASKAP radio telescope in western Australia.</p><p>After that, the team tried to find the object in visible light, but they came up empty-handed. They couldn't find it in X-ray or infrared light, either.</p><p>So they switched back to radio waves, at first using Australia's Parkes radio telescope, but they lost the source of the signal and couldn't detect anything for a while. Then they turned to a different radio telescope - the MeerKAT observatory in South Africa - and observed the area for 15 minutes every few weeks.</p><p>Finally, they caught the radio signal once more, but it disappeared in a single day. That was strange, since the six signals they'd caught with ASKAP had each lasted for weeks.</p><p>"This object was unique in that it started out invisible, became bright, faded away, and then reappeared. This behavior was extraordinary," Tara Murphy, a professor at the University of Sydney who is Wang's PhD supervisor, said in the release.</p><p>Murphy and Wang are not talking about visual brightness - a "bright" radio signal is just a strong one.</p><p>"The brightness of the object also varies dramatically, by a factor of 100," Wang said in the release.</p><p>In an email, Murphy told Insider "that is part of what makes it unusual."</p><p>"Objects that are hot (e.g. stars) typically emit visible light, which is why we ruled out a normal star as one of the possible interpretations for this object," she wrote. "It could be a very very cool star that is too weak to detect the visible light from but has bright radio flares."</p><p>The mysterious radio signal shares some traits with signals from a class of objects called "galactic center radio transients" that were discovered in the 2000s. But researchers don't know much about those objects either, except that they emit low-frequency, highly polarized radio waves with no detectable X-rays. Still, the new signal has properties that don't match those from the radio transients.</p><p>"We don't really understand those sources, anyway, so this adds to the mystery," Wang's co-supervisor, David Kaplan from the University of Wisconsin-Milwaukee, said in the release.</p>

Mysterious radio waves are radiating from an unknown object at the heart of the Milky Way, astronomers say

<p><div class="KonaFilter image-container display-table full"><div><div class="image on-image"></div><p></p></div></div>The solar flare that <a href="http://www.businessinsider.com/how-to-watch-extreme-solar-flare-2014-9">erupted on Wednesday</a> will be putting on a spectacular show this weekend, when the second of two <a href="http://solarscience.msfc.nasa.gov/CMEs.shtml" target="_blank">coronal mass ejections</a> - charged gases shooting out from the sun - is projected to arrive.</p>
<p>These powerful solar storms will produce auroras that will potentially <a href="http://www.accuweather.com/en/features/trend/northern_lights_viewing_condit/33834457" target="_blank">be visible in the central and northeastern U.S.</a> during the late hours on Friday and Saturday, according to Tony Phillips at <a href="http://spaceweather.com/" target="_blank">spaceweather.com</a>. Auroras are natural nighttime light displays that are usually only visible in the northernmost parts of the world.</p>
<p>Here's a helpful <a href="http://www.accuweather.com/en/features/trend/northern_lights_viewing_condit/33834457">AccuWeather map of where the aurora</a> will appear:</p>
<p><div class="KonaFilter image-container display-table full"><div><div class="image"></div><p></p></div></div>For any intrepid sky-watchers who are lucky enough to be in the visibility zone, the best time to look up will be after midnight, in every time zone, on Friday and Saturday.</p>
<p>Viewers in Washington state, most of Oregon, Idaho, Wyoming, Nebraska, Minnesota, the northern parts of Nevada, Utah, and Colorado, western Iowa, and the southeast part of South Dakota have the best chance of seeing the aurora, about 45%.</p>
<p>It's a coin toss, but one that could result in unforgettable beauty.</p>
