The project, known as LEGUS (Legacy Extra Galactic UV Survey), researchers used Hubble\u2019s Wide Field Camera 3, and the Advanced Camera to capture both ultraviolet and visible images of 50 neighboring galaxies, which lie within a 60 million-light-year radius of Earth, over the course of a year.<\/p>\n
The astronomers captured images of around 8,000 young star clusters, or groups of stars which are gravitationally bound, and catalogued 39 million individual stars, ranging in age from one billion to several billion years old.<\/p>\n
The scientists hope data collected by the survey will provide new insights into the complexities of star formation and galaxy evolution.<\/p>\n
“There has never before been a star cluster [catalog] and a stellar catalog that included observations in ultraviolet light,” Daniela Calzetti, an astronomer from the University of Massachusetts Amherst, who led the LEGUS survey, said in a statement.<\/p>\n
“Ultraviolet light is a major tracer of the youngest and hottest star populations, which astronomers need to derive the ages of stars and get a complete stellar history. The synergy of the two catalogs combined offers an unprecedented potential for understanding star formation,” she said.<\/p><\/blockquote>\n

Even today, with access to unprecedented astronomical data, astronomers still do not understand many aspects of how stars form. The new findings may help to change that, as the data will be made available to researchers who want to investigate how star formation occurred in either one specific galaxy or set of galaxies.<\/p>\n
One of the main issues that the survey may help to address is the connection between star formation and the major structures that make up a galaxy, such as spiral arms.<\/p>\n

Seems NASA is back in the game after cutbacks imposed by the previous administration. Manned asteroid exploration and both robot and manned missions to Mars are in the offing. Good to see you back, NASA.<\/p>\n","protected":false},"excerpt":{"rendered":"
