Messier 24 ist ein sichtbarer Teil des Sagittarius-Spiralarms der Milchstraße. Nach dem Aussehen der Sternwolke prägte Angelo Secchi (Vatikansternwarte) um 1850 den Namen Delle Caustiche. Heute wird sie meist Sagittarius-Wolke bzw. kleine Sagittarius-Wolke genannt – zur Abgrenzung von der großen Sagittarius-Wolke, einem sichtbaren Teil des Zentralbereichs der Galaxis etwas weiter südlich.

Während die zentralen und alle fernen Teile der Milchstraße durch interstellaren Staub verdeckt und damit für das menschliche Auge nicht sichtbar sind, erlaubt hier ein Fenster in der Staubverteilung den Blick auf einen Ausschnitt nahe dem galaktischen Zentrum. Normalerweise verschluckt hier der Staub 20-30 Helligkeitsstufen des Lichts [3]. In diesem Sinne kann das Objekt Messier 24 auch als Himmelsregion mit wenig Absorption bzw. interstellarem Staub aufgefasst werden.

Das Gebiet liegt im Sternbild Schütze und hat eine scheinbare Ausdehnung von rund 2° × 1°. Die Sternwolke ist etwa 10 000 Lichtjahre entfernt. Sie enthält mehrere Offene Sternhaufen, wobei insbesondere NGC 6603 hervorsticht. Ferner heben sich unter anderem die zwei Dunkelwolken Barnard 92 und Barnard 93 vor dem Hintergrund der Sagittarius-Wolke deutlich ab (Wikipedia).

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
