Milky Way shooting out cold and dense gas from galactic centre 'like bullets': Study

As outer continues to baffle scientists with its unique characteristics, researchers have recently discovered a previously unkwn cold gas being ejected from centre of our galaxy, Milky Way.

As per study published in journal Nature, scientists have clue about source of strange gas that is being shot “like bullets” from chaotic galactic centre. Even though astromers have t derived source, it can have critical implications on future of Milky Way. 

authors wrote, “Here we report observations of molecular gas outflowing from centre of our Galaxy. This cold material is associated with atomic hydrogen clouds travelling in nuclear wind”.

Professor Naomi McClure-Griffiths from Australian National University ted ability of galaxies to ‘shoot mselves in foot’. Furr elaborating about cold gas, she said that when a galaxy drives out a significant amount of mass, same material can be used to form stars. However, when eugh of it is lost, galaxy becomes unable to form stars anymore. According to her, it is “kind of exciting” to be able to see indications of Milky Way losing this star-forming gas from supermassive black hole. 

As per study, “ data also suggest that mass of molecular gas outflow is t negligible and could affect rate of star formation in central regions of Galaxy.”

Questions about Milky Way’s centre

new study has even raised a few questions about centre of Milky Way. McClure-Griffiths ted that since discovery of ‘Fermi bubbles’ that are filled with hot gas and cosmic rays, centre of galaxy h been mysterious. According to her, researchers have w detected cold and dense gas coming out from galactic centre but because y are heavier, gas comes out easily. 

"We don't kw how eir black hole or star formation can produce this phemen. We're still looking for smoking gun, but it gets more complicated more we learn about it," ded Dr Enrico Di Teodoro, le author on study, from Johns Hopkins University.
