The Solar System, and the other stars/dwarfs listed here, are currently moving within (or near) the Local Interstellar Cloud, roughly 30 light-years (9.2 pc) across. The Local Interstellar Cloud is, in turn, contained inside the Local Bubble, a cavity in the interstellar medium about 300 light-years (92.0 pc) across.
The project asks members of the public to go outside on dark moonless nights and report how many stars are visible in particular constellations. [1] [3] The project focuses on students, teachers, and families, and has produced activity packets in 13 languages. [3] [10] NASA encourages students in its INSPIRE program to participate. [11]
Below there are lists the nearest stars separated by spectral type. The scope of the list is still restricted to the main sequence spectral types: M , K , F , G , A , B and O . It may be later expanded to other types, such as S , D or C .
Paranal Observatory nights. [3] The concept of noctcaelador tackles the aesthetic perception of the night sky. [4]Depending on local sky cloud cover, pollution, humidity, and light pollution levels, the stars visible to the unaided naked eye appear as hundreds, thousands or tens of thousands of white pinpoints of light in an otherwise near black sky together with some faint nebulae or clouds ...
This list of nearest bright stars is a table of stars found within 15 parsecs (48.9 light-years) of the nearest star, the Sun, that have an absolute magnitude of +8.5 or brighter, which is approximately comparable to a listing of stars more luminous than a red dwarf.
At first, it looks like a planet: dark, snow-speckled and slashed down the center by a deep red scar. But zoom in a little closer, and you realize you're looking at something much larger than a ...

[citation needed] The surveys are most often made of nearby stars in the Milky Way galaxy. [citation needed] The total number of stars counted in a particular direction depends on the location and density of stars, the luminosity function, and the absorption. [2] Star count programs can therefore collect data that bounds or determines these ...
