Overview

ℹ️

Hourglass Nebula is a rich, very dense object of high C3 quality. Its parallax locates it at a relatively close distance, near the mid-plane. It is catalogued as a very young cluster (see Parameters). It is rarely studied in the literature, with no articles listed in the last 13 years.

⚠️ Warning: This is possibly a duplicate object, which shares a significant percentage of members with at least one previously reported entry. See table with shared members information.

Relatively close Very young

Morales et al. (2013)
Classified as morphological type 'EC1' (deeply embedded cluster). Morphological flag: cluster fully embedded, presence of emission related to PAH or warm dust.
