Into the Okavango is a 2018 American National Geographic documentary film written, directed and produced by Neil Gelinas. [1][2] It focuses on a team of modern-day explorers who go for a 1500 mile, four-month expedition through Angola, Botswana and Namibia to save the Okavango River that joins the Okavango Delta. [3][4] The film was ...
A gamma ray, also known as gamma radiation (symbol. γ. ), is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei. It consists of the shortest wavelength electromagnetic waves, typically shorter than those of X-rays. With frequencies above 30 exahertz (3 × 1019 Hz) and wavelengths less than 10 ...
English. Box office. $1,858,064. Arctic Tale is a 2007 American documentary film from the National Geographic Society about the life cycle of a walrus and her calf, and a polar bear and her cubs, in a similar vein to the 2005 hit production March of the Penguins, which was adapted for an English-language release by National Geographic.
The history of gamma-ray [1] began with the serendipitous detection of a gamma-ray burst (GRB) on July 2, 1967, by the U.S. Vela satellites. After these satellites detected fifteen other GRBs, Ray Klebesadel of the Los Alamos National Laboratory published the first paper on the subject, Observations of Gamma-Ray Bursts of Cosmic Origin.

This is a list of films produced and released by National Geographic under their feature Documentary Films banner, established in 2017. [1] National Geographic Partners is a joint venture between The Walt Disney Company and National Geographic Society, initially established between 21st Century Fox and the National Geographic Society until Disney's acquisition of Fox's media assets on March 20 ...
The bright rings form as a result of X-rays scattered from otherwise unobservable dust layers within our galaxy that lie in the direction of the burst. Most observed events (70%) have a duration of greater than two seconds and are classified as long gamma-ray bursts.
The Gammasphere is a third generation gamma ray spectrometer used to study rare and exotic nuclear physics. It consists of 110 Compton-suppressed large volume, high-purity germanium detectors arranged in a spherical shell. [1] Gammasphere has been used to perform a variety of experiments in nuclear physics. Most experiments involve using heavy ...
The Moon as seen by the Energetic Gamma Ray Experiment Telescope (EGRET), in gamma rays of greater than 20 MeV. These are produced by cosmic ray bombardment of its surface. [1] Gamma-ray astronomy is a subfield of astronomy where scientists observe and study celestial objects and phenomena in outer space which emit cosmic electromagnetic ...
