This cosmic cloud, called Sharpless 2-106, is an area where stars (and planets) form.

WebA planet is an object that: Revolves around the sun. Has almost a spherical shape. Has sufficient gravity so that the space near its orbit can be free from other objects like rocks, asteroids, comets, etc. Pluto does not satisfy the last criterion as a comet-like object clutters its orbit. Hence, it is now called a dwarf planet. Read More ...
