NGC 4038/4039

French Version

Les galaxies des Antennes (NGC 4038 / NGC 4039 et aussi Caldwell 60 / Caldwell 61) sont une paire de galaxies en interaction située à environ 75 millions d'années-lumière dans la constellation du Corbeau.
Les deux galaxies de la paire sont de type magellanique. NGC 4038 est une galaxie spirale barrée et NGC 4039 est une spirale ordinaire. Cette paire a été découverte par l'astronome germano-britannique William Herschel en 1785.

Les galaxies des Antennes sont le résultat d'une collision galactique. Situées dans le groupe de NGC 4038 avec au moins 26 autres galaxies, ces deux galaxies sont connues sous le nom d'« Antennes » parce que les deux grandes excroissances formées d'étoiles de gaz et de poussières éjectés hors de leur galaxie lors de la collision ressemblent aux antennes d'un insecte.
Les noyaux des deux galaxies sont en train de fusionner lentement et de devenir une unique galaxie.

Dans plusieurs millions d'années, les noyaux galactiques de NGC 4038 et NGC 4039 entreront en collision, devenant un noyau simple entouré d'étoiles, de gaz et de poussière. Certaines observations et simulations suggèrent que ces galaxies fusionneront finalement en galaxie elliptique.

english version

The Antennae galaxies (NGC 4038 / NGC 4039 and also Caldwell 60 / Caldwell 61) are a pair of interacting galaxies located about 75 million light-years away in the constellation Raven.
Both galaxies in the pair are of the Magellanic type. NGC 4038 is a barred spiral galaxy and NGC 4039 is an ordinary spiral. This pair was discovered by German-British astronomer William Herschel in 1785.

The Antennae galaxies are the result of a galactic collision. Located in the NGC 4038 group with at least 26 other galaxies, these two galaxies are known as the "Antennae" because the two large star-shaped growths of gas and dust ejected from their galaxy during the collision resemble the antennae of an insect.
The nuclei of the two galaxies are slowly merging and becoming a single galaxy.

Millions of years from now, the galactic nuclei of NGC 4038 and NGC 4039 will collide, becoming a single core surrounded by stars, gas, and dust. Some observations and simulations suggest that these galaxies will eventually merge into an elliptical galaxy.

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.
