"Dedicated amateur astronomers often make intriguing discoveries – particularly of fleeting astronomical phenomena such as supernovae and comets," NASA. At the time of writing, it's the last-released Hubble photo for the year.: galaxy NGC 3568 with its hazy gas and glimmering stars roiling through space here beneath the extra bright and much closer stars from our own galaxy.Galaxy NGC 3568.
NGC 3568's rivers of stars swirl in a barred spiral shape with two sweeping arms seen here side-on.

all galaxies are thought to be spiral galaxies and two-thirds of those seem to be barred, including our own Milky Way.revealed the barred types were seen far less in this part of the universe 7 billion years ago compared to the amount we see today. This suggests they may be an older stage of a galaxy's life cycle – forming gradually as masses of stars slightly deviate from their circular path around the galaxy's center.IBM astronomer Bruce Elmegreen at the time.
