An extreme example of visible light extinction, caused by a dark nebula. In astronomy, extinction is the absorption and scattering of electromagnetic radiation by dust and gas between an emitting astronomical object and the observer. Interstellar extinction was first documented as such in 1930 by Robert Julius Trumpler.
A comparison of this value with the apparent magnitude allows the approximate distance to be determined, after correcting for interstellar extinction of the luminosity because of gas and dust. In a gravitationally-bound star cluster such as the Hyades, the stars formed at approximately the same age and lie at the same distance. This allows ...
Christopher Nolan's sci-fi film, starring Matthew McConaughey, Jessica Chastain and Anne Hathaway, hit theaters 10 years ago
The reachable Universe as a function of time and distance, in context of the expanding Universe.. In cosmology, the event horizon of the observable universe is the largest comoving distance from which light emitted now can ever reach the observer in the future.
These three adjectives refer to the overall geometry of the universe, and not to the local curving of spacetime caused by smaller clumps of mass (for example, galaxies and stars). If the primary content of the universe is inert matter, as in the dust models popular for much of the 20th century, there is a particular fate corresponding to each ...
A disturbing detail about Interstellar has been uncovered in celebration of the film’s record-breaking re-release.. The Christopher Nolan film, which is still generating theories to this day ...
A physical state in which an interstellar cloud of gas will begin to undergo collapse and form stars. A cloud can become unstable against collapse when it cools sufficiently or has perturbations of density, allowing gravity to overcome the gas pressure. Julian year (a) A unit of time defined as exactly 365.25 days of 86,400 SI seconds each.
Interstellar is a 2014 epic science fiction film directed by Christopher Nolan, who co-wrote the screenplay with his brother Jonathan. It stars Matthew McConaughey , Anne Hathaway , Jessica Chastain , Bill Irwin , Ellen Burstyn , and Michael Caine .
