Whether they're nebulae, star formations, supernovae or planetary landscapes, images from space fascinate the designer Christopher Kane.
But then he went on: "That's right, M83 was discovered in 1751 by Abbe Nicholas Louis de la Caille and if you see an image of it there's red knots which represent diffusing gaseous nebulae in which star formation is just taking place, and which are excited to shine by its very hot young stars.
If the dust-to-gas ratio in the proto-solar nebula was 10−4, planet formation might have been difficult.
At 4.56 Ga, the accretion of the slowly rotating Solar Nebula led to the formation of Sun and its Planets in the plane of disc of accretion.
In particular, we discuss simulations showing that the interaction of a light, ultra-relativistic pulsar wind with a slow, dense ambient medium can give rise to asymmetry reminiscent of the Guitar nebula leading to the formation of a relativistic backflow harboring a series of internal shockwaves.
Observations of the nebula have revealed approximately 700 stars in various stages of formation within the nebula.
These "cosmic butterflies" — actually a certain type of planetary nebula — all have their own formation histories, and they don't interact with each other.
However, the minimum mass nebula capable of terrestrial planet formation can only form cores at the distance of Jupiter (5 AU) within 10 million years.
The structure of the bright portion of the nebula is primarily caused by the interaction of a fast stellar wind being emitted by the central star with material ejected during the formation of the nebula.
Outside the bright inner portion of the nebula, there are a series of concentric rings, thought to have been ejected before the formation of the planetary nebula, while the star was on the asymptotic giant branch of the Hertzsprung-Russell diagram.
