Electron-capture supernovae (ECSNe) are stellar explosions that occur in stars with initial masses around 8–10 times that of ...

According to the laws of physics, matter and antimatter behave the same way and were formed in equal quantities in the Big ...

The molecular hydrogen ion H₂⁺ is the simplest molecule. This simplicity makes it a perfect study object for physicists, as its properties—for example, its energy levels—can be calculated precisely.
