Main Points:

Astronomers have found that stars in the very beginning of universe used very little dust. This finding has enhanced the mysteriousness of the formation of very early stars. Read more…

An interactive presentation about the location of 32 nearby Stars

Interactive presentation of the location of the nearby stars

I have found an orthographic projection of 32 nearby stars and I thought you would like it too. These 32 stars are present within 14 light-years from the sun and presented by Krystian Majewski.

This presentation shows the stars in spectral color that may not be the actual color and many of the stars are dwarf stars.

You can find the list of the neighboring stars on Wikipedia here. You can also get the information about the star while moving the cursor over the dot.

You can find that interactive presentation here: http://kisd.de/~krystian/starmap/
