History of Globulettes in the Milky Way
  Globulettes are small (radii $< 10$ kAU) dark dust clouds, seen against the
background of bright nebulae. A majority of the objects have planetary mass.
These objects may be a source of brown dwarfs and free floating planetary mass
objects in the galaxy. In this paper we investigate how many globulettes could
have formed in the Milky Way and how they could contribute to the total
population of free floating planets. In order to do that we examine H-alpha
images of 27 H~II regions. In these images, we find 778 globulettes.
  We find that a conservative value of the number of globulettes formed is
$5.7\times 10^{10}$. If 10 \% of the globulettes form free floating planets
then they have contributed with $5.7\times 10^{9}$ free floating planets in the
Milky Way. A less conservative number of globulettes would mean that the
globulettes could contribute $2.0\times 10^{10}$ free floating planets. Thus
the globulettes could represent a non-negligible source of free floating
planets in the Milky Way.
