I wasn't going to try to identify the most prominent objects in the Milky Way in this APOD, but I'll have a go at it! (And please
forgive my most terrible handwriting using pencils to place numbers of the objects in the Milky Way.
Lower part of the Milky Way APOD.png
Number one is The North America Nebula
, NGC 7000, and A-type supergiant star Deneb
Number 2 is the Sadr (Gamma Cygni) region
, which contains a lot of nebulas and stars and star clusters. Number 3 is Vega
, and - oh! I forgot Altair
! Well, no matter, because if you look at the annotated image at right, you can see both Deneb, the North America Nebula right next to Deneb, the Sadr region, Vega and Altair. The photographer calls himself AstroBackyard, and I think his first name is Trevor. Note, when you try to find Altair in the image that I have annotated, that Altair is far to the right. Maybe you can see a white pinprick at about 3 o'clock? That's Altair.
I'm not absolutely sure what number four is, but I think it might be open clusters IC 4756 and NGC 6633
. The photographers may possibly be Till Credner and Sven Kohle.
Number five is the Scutum star cloud
, perhaps most famous because bright open cluster M11
is seen in front of it. The pictures are by Matija Pozojevic and R Jay GaBany.

Let's look at the middle part of the APOD. Number five is, again, the Scutum star cloud. Number six is the M16
region. They are two bright nebulas. You can see them here
. M17 is to the left in this picture. The photographer is Michael S
Number seven is the Small Sagittarius Star Cloud
, also known as M24
, a region which is quite full of bright young stars. The link goes to an APOD, complete with a caption, and not directly to the image. The Small Sagittarius Star Cloud is the bluish region at lower left in the APOD.
Number eight is the Lagoon Nebula
, seen here
with the Trifid Nebula
in a picture by Fred Espenak. The Lagoon Nebula is much larger and brighter than the Trifid Nebula.
Number ten is Jupiter
, unless I'm very much mistaken. Jupiter is seen here
in a picture by NASA, ESA, and A. Simon.
Number eleven is the Antares
and Rho Ophiuchi
region. This region is seen here
in a picture by Samuel Muller. Antares is the bright orange star, surrounded by a yellow reflection nebula, and Rho Ophiuchi is the brightest blue patch in the picture.
Number twelve is the "False Comet
", seen in a picture by stevec35. The False Comet
consists of a nebula called the Prawn Nebula
, and bright cluster named NGC 6231. The False comet is anchored by stars Zeta 1 and Zeta 2 Scorpii. You can see a picture of NGC 6231 and Zeta 1 and Zeta 2 Scorpii by Josef Pöpsel and Stefan Binnewies here
Okay, this took some time, so I'll do the last third of this post tomorrow (or more likely, make a new post for the last third of identifying objects in the Milky Way.
