[00:00:00]In just a tenth of a second, the magnetar SGR 1806-20 unleashed more energy than our sun emits in a hundred thousand years. Magnetars are the universe's rarest neutron stars, forged in supernovae and armed with magnetic fields up to 1,011 Teslas, a trillion times stronger than Earth's.

[00:00:22]Only about 24 are known, making them cosmic outliers. Their fields are so intense they can shatter atoms and trigger violent flares. And they're now linked to mysterious fast radio bursts.

[00:00:34]In 2024, astronomers witnessed SN 2024AFAV's light curve chirp, the first time general relativity's lens-thirring precession explained a supernova's mechanics. Want to dive deeper into these cosmic powerhouses? Read the full article for more awe-inspiring discoveries.
