Messier 3, Globular Cluster

Charles Messier entdeckte am 3. Mai 1764 diesen beeindruckenden Kugelsternhaufen im Sternbild Jagdhunde. Mit über 500 000 Sternen gehört er zu den Sternreichsten dieser Art. Sein Gezeiten Durchmesser beträgt 226 Lichtjahre in einer Entfernung von 33900 Lichtjahren. Die Ausdehnung beträgt ca. 18 Bogenminuten. Bisher sind 224 Variable Sterne nachgewiesen. Mit rund 4% an schweren Elementen im Vergleich zur Sonne gilt Messier 3 als sehr metallreich und ist Prototyp dieser Klasse von Kugelsternhaufen.

Charles Messier discovered on 3 May 1764 the impressive globular cluster in the constellation Canes Venatici. With over 500,000 stars, it is one of the star-rich of its species. Its tidal diameter is 226 light-years at a distance of 33900 light-years. The expansion is about 18 arcmin. So far, 224 variable stars have been detected. With around 4% of heavy elements compared to the Sun, Messier 3 is considered to be very metal-rich and is the prototype of this class of globular clusters.

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.
