- Amaterasu particle (Wikipedia)
The Amaterasu particle, named after the sun goddess in Japanese mythology, was an unexpected ultra-high-energy cosmic ray detected in 2021 and later identified in 2023, using the Telescope Array Project observatory in Utah, United States. It had an energy exceeding 240 exa-electronvolts (EeV) and was inferred through the two dozen particles it sent toward ground detectors. This single particle appears to have emerged, inexplicably, from the Local Void, an empty area of space bordering the Milky Way galaxy. The single subatomic particle held energy roughly equivalent to a brick dropping to the ground from waist height.
- Strait of Sicily (Wikipedia)
The Strait of Sicily (also known as Sicilian Strait, Sicilian Channel, Channel of Sicily, Sicilian Narrows and Pantelleria Channel; Italian: Canale di Sicilia or the Stretto di Sicilia; Sicilian: Canali di Sicilia or Strittu di Sicilia, Arabic: مضيق صقلية Maḍīq Ṣiqillīyah or مضيق الوطن القبلي Maḍīq al-Waṭan al-Qiblī) is the strait between Sicily and Tunisia. The strait is about 145 kilometres (90 mi) wide and divides the Tyrrhenian Sea and the western Mediterranean Sea, from the eastern Mediterranean Sea. The maximum depth is 316 meters (1,037 ft). The island of Pantelleria lies in the middle of the strait.
