- Is the angular size of the black hole in the movie interstellar . . .
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
- What are the differences between Intergalactic Medium, Interstellar . . .
The interstellar medium (ISM) is, as you say, the gas (and dust) in between the stars, within a galaxy It consists of molecular, neutral and ionized gas, with densities ranging from $\sim 10^ {-3}$ to $\sim 10^ {6}$ particles per cm $^ {3}$ and temperatures ranging from a few K up to 10,000 or 20,000 K
- 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
- 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?
- 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?
- orbital mechanics - Identification and discovery of interstellar . . .
Considering the recent announcement by NASA of the discovery of a new interstellar object, 3I ATLAS, I would like to ask a few questions about the process that leads to the identification of an obj
