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.
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.
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.
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 ...
In physical cosmology, the Big Rip is a hypothetical cosmological model concerning the ultimate fate of the universe, in which the matter of the universe, from stars and galaxies to atoms and subatomic particles, and even spacetime itself, is progressively torn apart by the expansion of the universe at a certain time in the future, until distances between particles will infinitely increase.
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 distant alien world that was potentially on its way into exile in interstellar space was rescued by the gravitational pull of a passing pair of stars, a new study argues.These findings support ...
