Arp 273 is a pair of interacting galaxies, lying 300 million light years away in the constellation Andromeda.

The larger of the spiral galaxies, known as UGC 1810, is about five times more massive than the smaller galaxy. Were we can see:

• It has a disc that is tidally distorted into a rose-like shape by the gravitational pull of the companion galaxy below it, known as UGC 1813;

• at the top there is a blue band consisting of clusters of young stars; the lower outer arm has an annular form which indicates that it has been crossed by the smaller galaxy;

• to the right, we can see a third galaxy with an upper outer part formed by many young and blue stars.

The smaller galaxy shows distinct signs of active star formation at its nucleus, a consequence of the gravitational interaction that manifests ever earlier in the smaller galaxy.

Its nuclei are separated by 100,000 light-years, a distance similar to the diameter of our galaxy.

When the Andromeda galaxy meets the Milky Way, a galactic rose may also form.

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.
