Is the angular size of the black hole in the movie interstellar . . . 3 I assume everybody is tired of reading questions derived from the movie Interstellar, I will try to keep this short and simple: In general in movies, in order to have stunning visuals, celestial objects are displayed as if they were extremely close to the observers, having a enormous apparent angular size
How cold is interstellar space? - Astronomy Stack Exchange The density of the interstellar medium is so very, very low that radiation losses completely dominate over conduction from the medium The interstellar medium can be very hot precisely because it is a gas (gases are a bit weird), and because it is extremely tenuous (extremely tenuous gases are beyond weird)
Is it possible for a meteor the size of the moon to enter our solar . . . And to answer the question about an interstellar "meteor the size of the Moon", that is even more impossibler than an interstellar "meteoroid the size of the Moon" A meteor is not a solid object It is a streak of light which people see in the sky as a meteoroid or an asteroid falls through Earth's atmosphere
Interstellar Dust properties - Astronomy Stack Exchange While practicing for an upcoming examination, I ran into this problem: Which of the following best describes dust grains in the interstellar medium: They are a few hundred nanometers in size (siz
Solar-system origin of interstellar bodies (like 1I ʻOumuamua)? I understand that 1I ʻOumuamua and the other two bodies (2I Borisov and 3I ATLAS) are classified as interstellar objects based on their distance from the Sun and their speed In other words the sum
What is the difference between gas and dust in astronomy? The temperature of interstellar medium seems to range mostly between 10 and 10 000 Kelvin Is gas dust an analog for hot cold, or does the phase diagram of the element in question matter too?
Why does rotation prevent the further contraction of the cloud? In the book Horizons: Exploring the Universe (2018) by M Seeds and D Backman, chapter 9, page 170-171, it states that: At least four factors resist the compression of an interstellar gas cloud, and
solar system - In theory, could an object like Oumuamua have been . . . There are excellent answers at the recent related question, Can it be predicted if an Interstellar Object will get bound to the solar system by knowing its speed and direction? But I'll take this opportunity to give some actual numbers relevant to the trajectory of 'Oumuamua Horizons has a file for 'Oumuamua From the body data page,
terminology - Is intrastellar commonly used by astronomers to refer . . . Quick checks of a few of them show a mixture of simple typos (i e , "intrastellar" used when "interstellar" is clearly meant), awkward failed attempts at synonyms for "intracluster stellar light", and actually correct uses meaning "inside a star" would extrasolar be used by astronomers to refer to objects outside of our solar system?
