The universe will certainly not cease to surprise us. Regularly, he reveals new things to us. unexpected. a surprise. confusing. And today again, a mysterious being illuminates the sky with radio waves like no other.
in a’, there is what we see. But there are also many things that we do not see. The things that light up the sky which are out who looks. From (Icrar, Australia) I discovered a new one. wave source As never seen before.
“It’s almost scarycomments by Natasha Hurley Walker, Researcher at Curtin University (Australia) in A. Because there is nothing known in heaven that does that.” Nothing known releases much Regularly every 20 minutes. Extremely bright source at only 4000 in Earth.

But make no mistake about it. theThey are used to observe things that they call transient. Things that look like they are flashing in the sky.

Could it be magnetic too long?
What makes this new element really special is that it lights up for one minute three times an hour. Other known transients could emit for a few days – that’s the case for– or for a few milliseconds or maybe a few seconds – when it comes to .
Astronomers also argue that the object is incredibly bright – in the field of radio waves, of course – and yet it is smaller than our sun. And it emits highly polarized radio waves. Which suggests not only that it is accompanied byEspecially powerful, but also capable of transforming this The magnetic field in radio waves is way more efficient than anything else we know.
This object can correspond to a kind of— a Extremely dense, sun-like star at the end of life – strange. Or even a class of things that are still completely unknown. But all of these characteristics lead researchers to think instead that it could be — a the case of de l For a massive star at the end of its life, surrounded by an intense magnetic field – a very long time that was never observed. The topic has already been imagined by theorists. But no one seemed to expect him to be that good. It remains to be seen whether astronomers will be able to find these other objects in the MWA archive or if it is an exceptional object.
