Herbig-Haro objects are small, wispy arcs of nebulosity formed when jets of gas from newborn stars collide with nearby clouds of gas and dust at high speeds. Of all deep space objects, they are among the smallest and fastest changing in shape. Changes in nebulae appearance can be seen from year to year in some objects. The first astronomers to study these objects in detail were George Herbig and Guillermo Haro, after whom they have been named.
I have verified many HH objects in my images. Unfortunately, most of the time they are just tiny wisps or faint specks. It is rare tor a HH object of decent size to be projected in such a way that it is clearly visible from our perspective. The poster shows the HH objects which I have found to be most visually interesting.
The location and data for the nebulae on this poster is shown in Revision B.
Below is a list of the 26 HH objects seen in the poster:
GM 1-29 – HH 215, HH 415
GN 22.55.2 – HH 168
HH 222 – HH 33, HH 34, HH40, HH 222
IC 5070 – HH 555
NGC 1333 – HH 7, HH 8, HH 10, HH 11, HH 12, HH 14
NGC 1999 – HH 1, HH 2, HH 3
NGC 2264 – HH 124, HH 571, HH 574
NGC 6726 – HH 100, HH 101
Sh2-239 – HH 28, HH 29, HH 102, HH 264
Each of the images of the poster has previously been uploaded and described individually on Astrobin. They all reside in my
