Health threats from cosmic rays are the dangers posed by cosmic rays to astronauts on interplanetary missions or any missions that venture through the Van-Allen Belts or outside the Earth's magnetosphere. [1] [2] They are one of the greatest barriers standing in the way of plans for interplanetary travel by crewed spacecraft, [3] [4] [5] but ...
The near side of the Moon is the lunar hemisphere that always faces towards Earth, opposite to the far side. Only one side of the Moon is visible from Earth because the Moon rotates on its axis at the same rate that the Moon orbits the Earth—a situation known as tidal locking . The Moon is directly illuminated by the Sun, and the cyclically ...
That night onward, Troi has trouble sleeping, encountering the same dream in which she levitates and drifts in the direction of a mysterious voice repeating, "Eyes in the dark, one moon circles". Four days later, with the investigation stalled, Captain Picard decides that the time has come to move on, but the crew find the ship also stalled ...
It is the only one of the lunar maria to be called an "Oceanus" (ocean), due to its size: Oceanus Procellarum is the largest of the maria ("seas"), stretching more than 2,500 km (1,600 mi) across its north–south axis and covering roughly 4,000,000 km 2 (1,500,000 sq mi), accounting for 10.5% of the total lunar surface area.

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 ...
Lunar maria (singular mare) are large, dark, regions of the Moon. They do not contain any water, but are believed to have been formed from molten rock from the Moon's mantle coming out onto the surface of the Moon. This list also includes the one oceanus and the features known by the names lacus, palus and sinus.
Background. The song was written by Benassi, Brown, Daniel Daley, Alle Benassi and Stephen Kozmeniuk.Brown and Benassi had worked together for the first time on the song "Beautiful People" in 2010, and subsequently Benassi had produced another track for Brown, "Don't Wake Me Up", in 2012.
It was seen on the night side of the Moon and appeared like a star of Magnitude 5 to the naked eye. On October 15, 1789, J.H.Schröter observed two bright bursts of light, each one of them composed of many single, separate small sparks, appearing on the night side of the Moon near crater Plato and Mare Imbrium.
