M 81 Bode ve M 82 Puro Gökadaları

M81, NGC3031 veya Bode gökadası, Dünya'dan 12 milyon ışık yılı uzaklıkta Büyük ayı takımyıldızında yer alan bir sarmal gökadadır. 1774 yılında Johann Elert Bode tarafından keşfedilmiş olup onun adını taşımaktadır. M81'in 250 milyara yakın yıldız içerdiğine inanılmaktadır. Dolayısıyla bu bakımdan Samanyolundan daha küçüktür. Biçimi itibariyle, muazzam bir sarmal gökada örneği teşkil eder. M81'in grubu olarak adlandırılan büyük gökada grubu içindeki en parlak gökadalardan biri olan M82 ile fiziksel bir çift oluşturur. Birkaç 10 milyon yıl önce bu iki gökada arasında bir yakınlaşma oluştuğu tahmin edilmektedir. Bu süre içinde daha büyük ve daha kütleli olan M81 çekimsel etkileşmeden dolayı M82'yi şekilsel olarak bozmuştur.

M 82, NGC 3034 veya Puro Gökadası, Büyük ayı takımyıldızı yönünde yaklaşık 12 milyon Işık yılı uzaklıkta bulunan, prototip bir gökadadır. Alman gökbilimci Johann Elert Bode tarafından 31 Aralık 1774 tarihinde keşfedilmiştir.

Bu düzensiz gökada, Samanyolu'ndan beş kez ve gökadamızın merkezinden de bir kat daha parlaktır.

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.
