Scientists discover giant doughnut-shaped galaxy, hope for insights on galactic structures

Scientists have discovered a galaxy that looks like a massive "cosmic ring of fire" and stated that discovery could help in learning more about evolution of galactic structures. incredibly rare kind of galaxy has a similar mass to that of Milky Way but is shaped like a doughnut with a hole in middle, according to a press release from ARC Centre of Excellence for All Sky Astrophysics in 3 Dimensions (ASTRO 3D) released on Monday, May 25.

Astromers have mand to capture an im of galaxy and revealed what it looked like 11 billion years ago. galaxy has been named R5519 and it is 11 billion light-years away from our Solar System. As ted by scientists, hole at its center has a diameter two billion times bigger than distance between Earth and sun. discovery is described in details in journal Nature Astromy.

A group of scientists from across  world used spectroscopic data to identify galaxy, and evidence suggests it may be first "collisional ring galaxy" located in early universe.

About collisional ring galaxies

Collisional ring galaxies are formed after colliding with or galaxies. It is said that discovery could help astromers understand how our own galaxy, Milky Way could have formed. As per study, it takes a "thin disk" of material present in one galaxy to collide with ar to form a collisional ring galaxy.

Spiral galaxies such as Milky Way also said have thin disks that started forming around nine billion years ago, but R5519 collisional ring galaxy is some 11 billion years old. This discovery indicates that disk assembly in spiral galaxies occurred over a more extended period than previously thought, said a scientist.
