MISTERIOSO SINAL DE ONDA DE RÁDIO DETECTADO NA VIA LÁCTEA!!

The team that discovered it thinks it could be a neutron star or a white dwarf – the cores of collapsing stars – with an ultra-powerful magnetic field. Spinning through space, the strange object sends out a beam of radiation that crosses our line of sight and, for one minute in every twenty, is one of the brightest radio sources in the sky. Astrophysicist Dr Natasha Hurley-Walker, from the Curtin University node of the International Centre for Radio Astronomy Research, led the team that made the discovery. “This object was fading in and out over the course of a few hours during our observations,” she said. “That was completely unexpected. It was kind of spooky for an astronomer because there’s nothing else in the sky that does that. “And it’s actually really close to us — about 4,000 light-years away. It’s in our galactic backyard.” Objects that switch on and off in the Universe are not new to astronomers - they call them 'transients'. ICRAR-Curtin astrophysicist and co-author Gemma Anderson said: "When you study transients, you are watching the death of a massive star or the activity of the remnants it leaves behind." 'Slow transients' - such as supernovae - can appear over a few days and disappear after a few months. 'Fast transients' - such as a type of neutron star called a pulsar - turn on and off in milliseconds or seconds. But Dr Anderson said finding something that switched on for a minute was really strange. She said the mystery object was incredibly bright and smaller than the Sun, emitting highly polarised radio waves - suggesting the object had an extremely strong magnetic field. strong.
