The Hubble telescope photographed an unusual "cosmic triangle"
Miscellaneous / / February 24, 2022
Telescope "Hubble" captured a pair of Arp 143 galaxies - the brighter NGC 2445 on the right and its companion NGC 2444 on the left in the image. As a result of their collision, a "cosmic triangle" was formed - a region of mass formation of stars.
Astronomers have explained that NGC 2445 is a distorted spiral galaxy saturated with gas. Since the structures in Arp 143 are close together, they hold each other in a "gravitational grip".
NGC 2444 was sucking gas from its companion. As a result, a kind of tsunami of relatively young blue stars formed 50–100 million years ago.
Closer to the center of the galaxy NGC 2445, astronomers looked at an even younger group of stars. Their age is 1–2 million years.
The galaxy NGC 2444 itself is formed by older stars. According to scientists, it lost gas even before the collision, so new stars are not born here.
