Oct 15, 2020 · 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.
The difference in density is huge, with interstellar medium density at an average of $\rho ∼ 1\ ppcm$ (one proton per cubic centimeter), but the density of these WHIM being even a few orders of magnitude lower at $\rho ∼ 10^ {−6}−10^ {−5}\ ppcm$, or roughly 1 to 10 protons per cubic meter (NASA's Chandra X-ray Observatory quotes ...
Jul 9, 2025 · 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...
Oct 29, 2021 · 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.
May 12, 2025 · Just how dense would interstellar matter have to be to even (practically) detect it with spectroscopy, if being near 0 kelvin (read: far away from nearby stars) affects its spectral readings?
4 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 …
Jun 2, 2016 · 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).
Mar 15, 2021 · 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...
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?
Jul 6, 2025 · 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...
