The Antennae Galaxies

The Antennae Galaxies are one of the youngest examples of colliding galaxies, as well as one of the nearest pairs of interacting galaxies to Earth. They are located in the constellation of Corus around 45 million light years away.

NGC 4038 and NGC 4039 were two separate galaxies some 1.2 billion years ago. The larger was a spiral galaxy, NGC 4039. The smaller galaxy was a barred spiral, NGC 4038.

About 600 million years ago, NGC 4038 and NGC 4039 passed through each other. At some point, they would have resembled the Mice Galaxies. Around 300 million years ago, the Antennae’s stars began to be released from both galaxies. These gravitational interactions have resulted in the long tails forming an antenna shape. Within the tails or streamers, areas of starburst activity exist.

Perhaps in the future, when our galaxy the Milky Way and the Andromeda galaxies come together, they may look similar to the Antennae during at least one point of their gravitational interaction.

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.
