Australian scientists solved the mystery of the peryton, a perplexing radio wave with an Earthly origin.
Astronomers also finally have a clue to what these things actually, spinning dead stars with extremely strong magnetic fields. “When you’re spinning around on a carousel, you have some rotational energy due to the fact that you’re spinning,” explains Alice Curtin, astronomy graduate student at McGill University. But magnetars also store energy in their magnetic fields.
FRBs have also proven to be an extraordinary resource for exploring the universe. “FRBs are encoded with information about all the stuff between us and them,” adds Curtin. Armed with their newly-expanded catalog of FRBs, astronomers can track hard-to-see dust and gas filling the spaces between the stars. When the FRB travels through matter in space, parts of it are slowed down, smearing out the FRB across frequencies.

#1 Dead Planets Society: Kill The SunThe sun is the centre of our solar system, the parent body to all the planets, unquestionably the most important cosmic object for life on Earth. But what if we were to destroy it?It turns out that is easier said than done. In the premier episode of the Dead Planets Society podcast, our hosts Leah Crane and Chelsea Whyte resort to extreme methods in their quest to put out the sun. They learn that adding a giant ball of water to the equation will only provide more fuel for the fire, stretching the sun into long noodle-like ribbons is only a temporary solution, and that there are no earthly weapons with enough power to take it out or force it to go supernova. They speak with planetary scientist Paul Byrne about the absurd methods we might use to quench our star and how these would play out if they were possible in real life. They are shooting for the stars, quite literally, and the consequences for Earth and the entire solar system are dire. Dead Planets Society is a podcast that takes outlandish ideas about how to tinker with the cosmos – from punching a hole in a planet to unifying the asteroid belt to destroying the sun – and subjects them to the laws of physics to see how they fare.To listen, subscribe to New Scientist Weekly or visit our podcast page here.
