Great clip. Opened another can of worms to sort out. Wonderful that there are reminders that we have a lot to learn and keep those clever minds ticking over.

Not all is lost! Star are still being born after all... even at the vicinity of the great void

Yet the alternative – stars falling inward after forming elsewhere – should be a rare occurrence.</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.sciencedaily.com/releases/2009/01/090105131212.htm">Using the Very Large Array of radio telescopes, astronomers from the Harvard-Smithsonian Center for Astrophysics and the Max Planck Institute for Radio Astronomy have identified two protostars located only a few light-years from the galactic center.
