O\u2019Doherty\u2019s object released huge bursts of radio waves every 18 minutes, with each burst lasting about one minute each.<\/p>\n<p>The object doesn\u2019t fit any known classification of stellar object, although it has properties similar to magnetars, a type of neutron star with a highly energetic magnetic field. Magnetars and their cousins, pulsars, emit electromagnetic radiation such as radio waves in regular bursts, according to how fast they spin, but the frequency of those bursts is 12 seconds at the longest and typically less than 1 second &#8211; the period on these two objects were 18 minutes and 22 minutes, respectively. Further, their bursts last for one to several minutes at a time &#8211; well beyond the duration of known magnetar or pulsar activity.<\/p>\n<p>The reason it isn\u2019t simply classified as another type of magnetar is that known magnetar properties dictate that they can only generate radio wave bursts by orbiting above a certain speed known colloquially as the \u201cdeath line.\u201d<\/p>\n<p>\u201cThe object we\u2019ve discovered is spinning way too slowly to produce radio waves &#8211; it\u2019s below the death line,\u201d Hurley-Walker said.Hurley Walker\u2019s team also looked at past data and found something remarkable: the object had actually been appearing in telescope images for more than 30 years.<\/p>\n<p>&#8220;It showed up in observations by the Giant Metrewave Radio Telescope (GMRT) in India, and the Very Large Array (VLA) in the USA had observations dating as far back as 1988,&#8221; she said.<\/p>\n<p><strong>For More News And Analysis About <a href=\"https:\/\/www.africa-press.net\/rwanda\">Rwanda<\/a> Follow <a href=\"https:\/\/www.africa-press.net\/\">Africa-Press<\/a><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Africa-Press &#8211; Rwanda.
