the strange powerful particle from empty space
Astronomers have spotted a strange and extremely powerful particle falling to Earth from an empty region of space. The particle, dubbed Amaterasu after the Japanese sun goddess, is one of the most energetic cosmic rays ever recorded. According to the Guardian, such particles can only be created by the most violent cosmic phenomena, far beyond…

NASA warns of giant sunspots and solar storm
The sun is experiencing a period of high magnetic activity, which has resulted in a series of sunspots and fiery eruptions on its surface. These phenomena could have implications for the Earth, as they could cause geomagnetic storms and radio blackouts. Sunspots and solar flares Sunspots are dark patches of concentrated magnetic energy on the…
