Arp 297 (Gary Imm)

Arp 297

This image contains many interesting tiny galaxies, located in the constellation of Boötes. Arp 297 is the a quartet of small galaxies seen towards the center. Although it appears to be a quartet, it is really two pairs of galaxies at drastically different distances.

The largest galaxy to us at an apparent span of about 1 minute, NGC 5754 is the beautiful face-on galaxy at the center of the image. This galaxy is located 200 million light years away along with its companion, NGC 5752. These two are clearly interacting, as indicated by the extra long tidal stream almost 300,000 light years long which very faintly extends down and to the right. It also appears that the smaller galaxy has a reddish tint, which may indicate a starburst phase from the interaction.

Just to the right of this pair of galaxies, NGC 5755 is a wonderfully bizarre spiral galaxy with distorted arms and long tidal streams. It is located 450 million light years away along with the inclined spiral galaxy NGC 5753 to its right, although it is not clear that these two are interacting at this time.

Among the other galaxies in the image are the following:

- A pair of contrasting color galaxies (blue and yellow) to the left of center.

- A pair of galaxies similar in structure and color to the lower left of center.

- Most interestingly, to the right of center, a strange object which looks like a star superimposed over an irregular galaxy, or perhaps a star illuminating a reflection nebula.

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.
