Astronomers have discovered SGR 0501+4516, a fast-moving magnetar racing at over 110,000 mph (177,000 km/h). This star, with a magnetic field so powerful it could rip atoms apart, is making scientists rethink everything we know about dead stars. Magnetars, which are the collapsed cores of massive stars, are already some of the densest objects in the universe. But SGR 0501+4516 is breaking all the rules.
First spotted in 2008, about 15,000 light-years away, this zombie star was thought to have come from a typical supernova. But recent data from the Hubble Space Telescope and ESA's Gaia spacecraft show it’s moving way faster than expected — suggesting it didn’t form in the usual way. In fact, it may have formed from the collapse of a white dwarf, a type of star that doesn’t usually create magnetars.
This discovery could also explain some of those mysterious fast radio bursts, intense flashes of radio waves from far-off galaxies. These bursts have baffled scientists because they seem to come from ancient galaxies, yet there are no dead stars around.
SGR 0501+4516’s magnetic field is 100 trillion times stronger than Earth’s. If it passed by Earth at half the distance to the Moon, its field could erase every credit card on the planet. And if a person got too close — within 600 miles — it would tear apart every atom in their body. Luckily, this magnetar is not coming anywhere near us.
This new discovery could change the way we think about magnetars and their role in some of the most powerful cosmic events. There's still much to learn, but this is a huge step forward in understanding the mysteries of the universe.
