Superluminous supernovae! We used to think they were powered by black holes. Turns out some are powered by magnetars, neutron stars with magnetic fields 1,000x stronger than usual. SN 2017egm, 440 million light-years away, proves it. The Earth is exciting, but space is too! 🤯
NASA's Fermi Telescope Finds Neutron Stars (Magnetars) Powering Superluminous Supernovae
New gamma-ray observations from NASA's Fermi Space Telescope suggest that highly-magnetic neutron stars, known as magnetars, are the hidden engines behind superluminous supernovae, a rare class of ste

Verrückter Fakt des Tages: Magnetare sind Neutronensterne mit einem Magnetfeld von ca. 1 Billion Tesla. Zum Vergleich: Kühlschrankmagnet hat ca. 0.001 Tesla, Magnete am CERN ca. 8 Tesla.
Das Feld eines Magnetars verändert die Struktur von Atomen so, dass Moleküle zerreißen. Materie würde verpuffen.

M81. This galaxy is thought to harbor magnetars, which are a type of dense neutron star with powerful magnetic fields. Magnetars may be the origin of the still mysterious fast radio bursts. At the bottom of the photo is the Cigar Galaxy. ~3hrs exposure on my tiny scope!

Lorsque certaines étoiles meurent, elles laissent derrière elles de nouveaux astres, parmi lesquels les magnétars. Ces objets ont des champs magnétiques plusieurs milliards de fois plus élevés que celui du Soleil. Des chercheurs tentent de comprendre pourquoi.

Magnetars are neutron stars -- they just have these unbelievably strong magnetic fields, much stronger than other neutron stars. These powerful magnetic fields produce weird behaviour, like X-ray bursts and giant flares.
Magnetars are cool, but also, terrifying.

Going to invent a guitar that has magnets below the strings and when the strings vibrate within the magnetic field it will make an ELECTRIC SIGNAL thus I will call this Magnet Guitar a MAGNETAR

I’m happy to say magnetars are already available.

fun idea for bored posthumans of the far future: cut down the free-space radiation dose from galactic cosmic rays in the Local Group to 'harmless to biolife' levels by encapsulating all local magnetars and active black holes and systematically siphoning mass off giant stars to prevent supernovae

The hardest part of creating a design? Posting it on social media, but anyway, here it is! Neutron stars are insanely dense,(teaspoon of neutron star would weight 4 billion tons on Earth). Some are pulsars, like beacons in space or/and magnetars!
