Atomic astrophysics is concerned with performing atomic physics calculations that will be useful to astronomers and using atomic data to interpret astronomical observations. Atomic physics plays a key role in astrophysics as astronomers' only information about a particular object comes through the light that it emits, and this light arises ...

The molecules in stars can be used to determine some characteristics of the star. The isotopic composition can be determined if the lines in the molecular spectrum are observed. The different masses of different isotopes cause vibration and rotation frequencies to significantly vary.
These are lists of songs.In music, a song is a musical composition for a voice or voices, performed by singing or alongside musical instruments. A choral or vocal song may be accompanied by musical instruments, or it may be unaccompanied, as in the case of a cappella songs.
Astrophysics is the branch of astronomy that deals with the physics of the universe, including the physical properties (luminosity, density, temperature, chemical composition) of astronomical objects such as stars, galaxies, and the interstellar medium, as well as their interactions.
The Free Music Archive (FMA) is an online repository of royalty-free music, currently based in the Netherlands. [1] Established in 2009 by the East Orange, New Jersey community radio station WFMU and in cooperation with fellow stations KBOO and KEXP , it aims to provide music under Creative Commons licenses that can be freely downloaded and ...

Elephant trunks (more formally, cold molecular pillars [1]) are a type of interstellar matter formations found in molecular clouds. They are located in the neighborhood of massive O type and B type stars , which, through their intense radiation, can create expanding regions of ionized gas known as H II regions .
