- 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 $\sim 10^ {-3}$ 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
- 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
- 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
- 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
- Solar-system origin of interstellar bodies (like 1I ʻOumuamua)?
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
- Why do comets come from our local Oort cloud instead of from . . .
But why are they ejected to form specifically a local Oort cloud instead of going interstellar and becoming vagabonds? Per multiple models, most comets did become vagabonds
- 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
- 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?
- 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
