Astronomers have recently discovered a new cold stream of molecular gas in a nearby galaxy, and the implications of this finding could be huge for our understanding of the universe. This cold gas stream is located in a galaxy called NGC 4258, and was found to be a continuous flow of gas from one end of the galaxy to the other. This stream is made up of mostly hydrogen and helium, and it is estimated that it could contain more than 10 million stars. This discovery could provide insight into how galaxies form and evolve, and could also help to explain why some galaxies have more stars than others. Additionally, this cold stream could be the source of new stars, and could also affect the evolution of other galaxies. This is an exciting finding that could completely change our understanding of the universe.
