  • Is the angular size of the black hole in the movie interstellar . . .
    One striking example of this that has seems counter-intuitive, is the angular size displayed for the black hole "Gargantua" in the movie Interstellar The characters in the movie are so close to it that it can be fully displayed in great detail (see attached image: Black hole seems to cover almost over 90 degrees of the field of view !)
  • 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 The molecular gas is the coldest and
  • Is interstellar matter even detectable at (near) 0 kelvin?
    Overall, interstellar matter cannot be observed in any way by thermal emission of energy, as it is near absolute zero However, it can certainly be observed spectroscopically by seeing how outside photons (at the left part of the EMS) excite electrons and make them reemit a similar photon
  • terminology - Is intrastellar commonly used by astronomers to refer . . .
    The CNET article Interstellar comet Borisov looks ordinary, making Oumuamua even weirder says: A paper published Monday in Nature Astronomy lays out the early data on Borisov, which is just the second-ever object seen visiting our solar system from beyond
  • How cold is interstellar space? - Astronomy Stack Exchange
    But since the interstellar medium (ISM) is so dilute, a normal thermometer will radiate energy away faster than it can absorb it, and thus it won't reach thermal equilibrium with the gas It won't cool all the way to 0 K, though, since the cosmic microwave background radiation won't allow it to cool further than 2 7 K, as described by David Hammen
  • rogue planet - Is it possible for a meteor the size of the moon to . . .
    An 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 movie: What is the portal to the other galaxy?
    I recently watched Interstellar with some friends and we didn't come to the same conclusion In my opinion, the portal they use to go to the other galaxy (to visit the three planets) is not a black hole My friends tell me it is (warning, contains spoiler!!) To me, it's not because of these points:
  • What is the difference between gas and dust in astronomy?
    Is there a strict difference between gas and dust? In Earthly environment most things become gaseous if heated enough 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?
    At least four factors resist the compression of an interstellar gas cloud, and those factors must be overcome by gravity before star formation can begin Third, everything in the Universe rotates As a gas cloud begins to contract, it spins more and more rapidly, just as ice-skaters spin faster as they pull in their arms
  • Do interstellar asteroids decelerate and eventually stop?
    When an interstellar body happens to approach a star it will start to fall towards it, and speed up If it doesn't hit the star it will pass by and slow down as it moves up from the star The velocity it loses as it moves away will be exactly the same as the velocity it gained while falling towards the star
