NASA uses Hubble telescope to discover two galaxies colliding with each other to form a face

NASA astronomers using the Hubble Space Telescope to observe the depths of space have discovered a pair of colliding galaxies that look a bit like a human face with two glowing eyes staring at us. Scientists say this image shows a head-on collision between two galaxies.

Each eye in the photo is a bright core of galaxies that collides with each other. The outline of the face is a circle of young blue stars. The nose and mouth in the image form other clusters. The system is currently numbered Arp-Madore 2026-424.

Galaxy collisions occur frequently, especially in the early days of the universe, but most collisions are not as frontal as they are now. The violent collision caused the system to form a ring structure. NASA says the ring structure lasted about 100 million years for a “short” time. The collision pulled out and stretched out the galaxy’s gas and dust disk, forming a nose and face. In order to make the two eyes in the photo almost equal in size, the two galaxies that collided were almost equal in proportion. The collision system was discovered during NASA’s Snapshot project.

Snapshot items take advantage of the occasional interval in the observation plan to take other images. Scientists plan to use the project in the future to study other abnormally interactive galaxies. Scientists will use the Hubble telescope to select the main targets and will use the James Webb Space Telescope to continuously observe the selected targets in 2021.
