NGC 5899 & 5900

This object is a pair of spiral galaxies located in the constellation of Bootes at a declination of +42 degrees. As shown in the mouseover, NGC 5899 is at bottom and NGC 5900 is at top. Both galaxies show signs of disturbance.

NGC 5899 is a 13.2 magnitude barred spiral galaxy located 150 million light years away. It spans 3.5 arc-minutes in our apparent view, which corresponds to an actual diameter of 150,000 light years. The disk is 15 degrees from edge-on in our view. The galaxy has an interesting disk structure, with one strong arm in the upper half of the disk.

NGC 5900 is a 13.4 magnitude barred spiral galaxy located 200 million light years away. It spans 2 arc-minutes in our apparent view, which corresponds to an actual diameter of 110,000 light years. The almost edge-on galaxy has a dark dust lane which meanders along the length of the disk. The most interesting feature in the image is a very faint star stream which starts at the lower end of this galaxy and arcs towards NGC 5899. This feature is a bit easier to see on the inverted Astrobin image.

Based on the distances above, these galaxies are not interacting. But both galaxies are disturbed a similar amount, no other galaxies are visible in this immediate area, and the star stream arc is suspicious. However, the distance estimates are confirmed by multiple sources, so I believe that these galaxies are not interacting with each other.

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.
