- 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
- 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 densest, usually found in molecular clouds The
- 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)
- the sun - How did the Local Interstellar Cloud form? - Astronomy Stack . . .
The Local Interstellar Cloud (LIC) is a low-density interstellar cloud which embed the Sun and other stars How did this region form? I suppose a supernova or stellar winds from multiple stars may
- interstellar medium - What is the word for space that is in the solar . . .
We distinguish space by its contents; the space within the heliosphere is called the interplanetary medium (it contains solar plasma, dust, etc ), while the interstellar medium comprises sparse gaseous molecules from the Local Fluff and (if you go far enough) the rest of the Local Bubble
- interstellar medium - Why does dust affect UV light more severe than it . . .
7 My supervisor told me that the UV photons emitted from AGN are heavily affected by ISM (dust extinction), but not X-rays, as described in Extinction - a powerful discriminator of dust size Since X-ray and UV are all photons with different levels of energy, why does dust (interstellar medium) affects UV more than X-rays?
- Nomenclature of Interstellar Objects and Stars
One type is diffuse nebulae, which are "clouds" of gas and dust in interstellar space, often many light years across They include emission nebulae which are heated by stars and so emit light, reflection nebulae which reflect light from stars, and dark nebulae which block light from stars and nebulae beyond them
- What long chain of carbon chemistry in the interstellar medium . . .
From that, I conclude that Cyclopropenylidene in the ISM (interstellar medium) is also a product of a long chain of carbon chemistry Question: What "long chain of carbon chemistry" in the interstellar medium produces cyclopropenylidene (C3H2)?
- 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
- What is the temperature of outerspace? - Astronomy Stack Exchange
In interstellar space there exist hot (e g 10,000 K) and cold gas clouds Due to the very low density, hot and cooler fractions can penetrate each other, such that there doesn't need to be a uniquely defined temperature The large-scale average temperature of outer space should be 2 7 K (about -270 5 C), close to the CMB black body temperature
