Galaxy NGC 4383 evolving strangely. Gas is flowing from its core at a rate of over 200 km/s. This mysterious gas eruption has a unique cause: star formation. Credit: ESO/A. Watts et al.
A team of international researchers studied galaxy NGC 4383, in the nearby Virgo cluster, revealing a gas outflow so large that it would take 20,000 years for light to travel from one side to the other.Monthly Notices of the Royal Astronomical SocietyResearchers Dr. Adam Watts and Professor Barbara Catinella discuss the discovery and gas pollution in space.

Gas outflows are crucial to regulate how fast and for how long galaxies can keep forming stars. The gas ejected by these explosions pollutes the space between stars within a galaxy, and even between galaxies, and can float in the intergalactic medium forever., co-led by ICRAR researchers Professors Barbara Catinella and Luca Cortese, who were also co-authors of the study.Very Large TelescopeThe MUSE instrument, attached to the Very Large Telescope in Chile.

“NGC 4383 was our first target, as we suspected something very interesting was happening, but the data exceeded all our expectations.
