Astronomers discover Enormous, Strange Structures Video in Neighboring-Galaxies

Some strange, double peanut shell-shaped structures were establish in two nearby disc galaxies. The stars in these galaxies are distributed in such a way that there is an enormous bulge at the center, creation the galaxies look rumpled—kind of like a nut.
Ultimately, these mysterious shapes have prompted astronomers at the Swinburne University of Technology in Melbourne to expand new imaging software that will, hopefully, make it possible to observe them improved and uncover their origins. These odd structures are found in NGC 128 and NGC 2549, and data from the Hubble Space Telescope and the Sloan Digital Sky Survey reveal that there is a second peanut shell profile structure.
They resemble 2 peanut shells, with one neatly nested within the other; this is the first time such a phenomenon has been observed,” says Bogdan Ciambur, a PhD student who leads the study.

Ciambur adds, “The discovery is exciting because it will enable us to extra fully test the growth of bars over- time, including their lengths, rotation speeds, and periods of instability.”
Hopefully, state-of-the-art simulations will also uncover the reason behind the peanut-shaped bulge. “We expect the galaxies’ surprising anatomy will give us with a unique view into their pasts. Deciphering their history can tell us concerning transformations that galaxies like our own Milky Way power experience.”
