Neutron Stars: Crash Course Astronomie #32

Neutron Stars: Crash Course Astronomie #32

În urma dispariției unei stele cu masă solară de 8-20, găsim un mic obiect ciudat cunoscut sub numele de stea neutronică. Stelele neutronice sunt incredibil de dense, se rotesc rapid și au câmpuri magnetice foarte puternice. Unele dintre ele le vedem ca pulsari, fulgerând în luminozitate în timp ce se învârt. Stelele neutronice cu cele mai puternice câmpuri magnetice se numesc magnetare și sunt capabile de explozii colosale de energie care pot fi detectate pe distanțe mari.

  1. The bigger question is, would flying into one of the jets really overclock your FSD without turning you into jelly?

  2. @alfonseanacrelico6828

    I LOVE this series. I'm an avid watcher of "How the Universe Works" and I love Phil in that series. But here I've learned much more detail than the TV series. Phil's enthusiasm for astronomy and teaching is wonderful and very engaging. I happened upon these YouTube videos by accident, and I'm very glad I did!

  3. That's a great explanation. Other channels rattle down the facts, but I've never learned about the issue of star quakes before. 🙂
