Hubblecast

Supersonic Jets From Newborn Stars (1x49)

:

In this episode of the Hubblecast, Joe Liske (aka Dr J) looks at newborn stars firing out jets of matter. These jets may cast new light on how the Sun formed 4.5 billion years ago. An international team of scientists led by astronomer Patrick Hartigan of Rice University in Houston, USA, has collected enough high-resolution Hubble images over a 14-year period to stitch together time-lapse movies of these jets.
