About two thirds of spiral galaxies, including the Milky Way, feature a central bar of stars and long arms spiralling loosely around the nucleus. NGC 613, discovered in 1798 by William Hershel, provides a textbook example as seen in this beautifully detailed image captured by the Hubble Space Telescope and released 11 January. NGC 613 is located about 67 million light years from Earth in the southern constellation Sculptor.
Peering deep into the early universe, this picturesque parallel field observation from the NASA/ESA Hubble Space Telescope reveals thousands of colourful galaxies swimming in the inky blackness of space in the constellation Sculptor. This spectacular skyscape was captured during the study of the giant galaxy cluster Abell 2744, otherwise known as Pandora’s Box.
A team of international scientists, led by astronomers from Cardiff University, has shown for the first time that galaxies can change their structure over the course of their lifetime. The researchers have shown that a large proportion of galaxies have undergone a major ‘metamorphosis’ since they were initially formed after the Big Bang.
