It seems that an extraordinary oval galaxy with a history of absorbing smaller galaxies is approaching its next goal.
New photos from Very large telescope (VLT) at the Paranal Observatory of the Southern European Observatory (ESO) indicates that the galaxy, known as NGC 3640, may soon merge with a smaller galaxy companion. 88 million light -years from landNGC 3640 belongs to a group of Galaxies This shape and size ranges, including its oval shape or unusual eggs.
the VLT photos It revealed that NGC 3640 has eaten other galaxies over the past billion years and a younger neighbor, known as NGC 3641, is now on its way. NGC 3641 is located below NGC 3640 directly in the modern image, and NGC 3641 may eventually be the next Galaxy meal.
“Throughout their very long lives, galaxies change,” said ESO officials at ESO at ESO. statement The new image is accompanied. “After these events, galaxies can become distorted, as shown by NGC 3640 derivative and light around it.”
As two galaxies approach each other, their attractiveness becomes increasingly strong, causing them to collide in the end and integrate into one larger galaxy. This, in turn, disrupts the original structures of both galaxies.
Fortunately, NGC 3641 may still have some time before his largest neighbor consumes him. The last VLT images do not show any signs that NGC 3641 is distorted by You approach the galaxyThe NGC 3640 proposal has not yet approached enough to form a threat.

Using new VLT images, astronomers at the Italian National Institute of Astronomical Physics enable NGC 3640. The collision between two galaxies is left “scars” on the remaining cosmic body, which generally contains some of the first stars created inside the original galaxy.
So, this Stars As “fossil signs” for the original Galaxy, however, how the team that NGC 3640 decided to overwhelm other galaxies, according to the statement.
The results they reached It was published on November 5, 2024 In the Journal of Astronomy and Astronomical Physics.
