Arcs and Jets in Herbig Haro 34
Explanation:
Some features of HH-34 are understood -- some are not.
At the core of
Herbig-Haro 34 lies a seemingly typical young star.
This star, though, somehow ejects energetic "bullets" of
high-energy particles,
appearing as red streaks toward the lower right of the
this image.
Astronomers speculate that a burst of these particles might
rebound when gas from a
disk
surrounding the star momentarily collapses onto the star.
Visible near the end of each
light-year long
jet is a glowing cap.
HH-34 lies about 1500 light-years away in the
Orion Nebula star-forming region.
The cause of the large arc of gas on the upper left known as
the waterfall remains unexplained.
