The Birth of Solar Systems
The Birthplace of Stars
Hot Stars make their Nurseries glow
Dark Clouds gather
Molecular Clouds
Where Stars Begin
A little bit of spin goes a long way…
The Sword of Orion
The glowing tip of a molecular “cigar”
Near them, lower mass stars are forming
They look like little windsocks
The heart of them contains a potential new solar system
Orion Proplyds
A whole cluster of new stars is born before us
The Star-Disk System Forms
And emits powerful bipolar jets
which extend for many light years
The jet shocks are called Herbig-Haro Objects
The jet is powered by the stellar magnetic field and rotation, and takes away excess angular momentum
piercing back out into the cloud
T Tauri Stars
The Young Star is Very Active
The stage is set for planet formation
We see remnant disks around other stars
Star Formation is Beautiful, but ephemeral
