APOD: Helping Hand in Cassiopeia (2024 Nov 08)

[APOD Robot]

Helping Hand in Cassiopeia

Explanation: Drifting near the plane of our Milky Way galaxy these dusty molecular clouds seem to extend a helping hand on a cosmic scale. Part of a local complex of star-forming interstellar clouds they include LDN 1358, 1357, and 1355 from American astronomer Beverly Lynds' 1962 Catalog of Dark Nebulae. Presenting a challenging target for astro-imagers, the obscuring dark nebulae are nearly 3,000 light-years away, toward rich starfields in the northern constellation Cassiopeia. At that distance, this deep, telescopic field of view would span about 80 light-years.

LDN 1358 (AllWISE)

Fantastic, Jac! What a hidden gem of a cluster!

I have to ask you about the star RZ Cas, the bright-looking bluish star near bottom right in the APOD. The star itself is a very modest quite nearby A-type star, and the nebulosity next to it has nothing to do with the bright-looking star.

Yes, but the nebulosity itself sure looks interesting. Could there be a hidden cluster there, too? What do you think, Jac?

ThanX Ann

I don't think so. There are individual stars, but no cluster like in LDN 1358 (left).

No?

It looks quite special.
