Cosmic ray visual phenomena, or light flashes ( LF ), also known as Astronaut's Eye, are spontaneous flashes of light visually perceived by some astronauts outside the magnetosphere of the Earth, such as during the Apollo program. While LF may be the result of actual photons of visible light being sensed by the retina, [1] the LF discussed here ...
Abundant visible light to the eyes gives health benefits through its association with the timing of melatonin synthesis, maintenance of normal and robust circadian rhythms, and reduced risk of seasonal affective disorder. [10] On the negative side, UV is a mutagen and carcinogen for skin.
Cosmic ray antiprotons also have a much higher average energy than their normal-matter counterparts (protons). They arrive at Earth with a characteristic energy maximum of 2 GeV, indicating their production in a fundamentally different process from cosmic ray protons, which on average have only one-sixth of the energy.

Faster-than-light ( superluminal or supercausal) travel and communication are the conjectural propagation of matter or information faster than the speed of light ( c ). The special theory of relativity implies that only particles with zero rest mass (i.e., photons) may travel at the speed of light, and that nothing may travel faster.
By the 1970s, the inner core was spinning a little faster than the planet. It slowed around 2008, and from 2008 to 2023 began moving slightly in reverse, relative to the mantle. Future core spin
While driving their jeep (the Createrra) across the African Savanna, Chris and Martin find a baby elephant separated from his mother. Martin names him Thornsley, and brings him back to the Tortuga HQ, only to discover the power of a baby African elephant, and the work necessary to take care of one.
We've all grown up thinking that sitting too close to the television is damaging to our eyes ... but that might not be the case. Technology spawns lots of confusion ... and a few affectionately ...
Citizen scientists spotted an object zipping through the Milky Way at more than 1 million miles an hour, and a new study shows it could be a rare hypervelocity star. An unusual object is moving so ...
