  • 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
  • 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?
  • Do interstellar asteroids decelerate and eventually stop?
    I do wonder, do interstellar asteroids eventually stop at one point in space after they gradually decelerate (or) even do they decelerate? Though there is no air like on earth and thus asteroids will not be affected by frictional forces, do they have friction with gravitational forces against their trajectories?
  • 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)
  • 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 ∼10−3 ∼ 10 − 3 to ∼106 ∼ 10 6 particles per cm 3 3 and temperatures ranging from a few K up to 10,000 or 20,000 K The molecular gas is the coldest and densest, usually found in molecular clouds The
  • interstellar medium - What is the diffuse ionized gas? - Astronomy . . .
    An interstellar cloud is generally an accumulation of gas, plasma, and dust in our and other galaxies Put differently, an interstellar cloud is a denser-than-average region of the interstellar medium, (ISM), the matter and radiation that exists in the space between the star systems in a galaxy
  • temperature - Cooling timescale for an interstellar dust grain . . .
    I would like to estimate the cooling timescale for an interstellar dust grain, starting at 200K, down to 100 K The equation I have come up with is: $\displaystyle t_ {cooling} = \frac {mC\Delta T} {Q
  • 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?
  • galaxy - Why is the metallicity of dwarf galaxies low? - Astronomy . . .
    Stars are the main progenitor of heavy elements - the interstellar medium is populated with such materials after a star's death Dwarf galaxies, with their low mass and size, have less available star-forming matter within the interstellar medium, resulting in a significantly lower stellar population than major galaxies like the Milky Way
  • interstellar medium - Speed of light through the ISM and Wavelength . . .
    You can find a neat description and some examples of the effect here This is known as the pulsar dispersion measure As you correctly say, waves with longer wavelength (lower energy photons) are delayed with respect to shorter wavelength radiation from the same phenomenon When electromagnetic waves travel through a plasma, they excite currents in the free charged particles In such cases it
