And it has done so without locking down entire cities or taking some of the…
Astronomers identify nearly 3,000 candidate stars of a nearby star-forming galaxy
Using the United Kingdom Infrared Telescope (UKIRT) and NASA’s Spitzer Space Telescope, astronomers have conducted photometric observations of a nearby star-forming galaxy known as NGC 6822. They have identified nearly 3,000 candidate stars of this galaxy, which is reported in a paper published February 27 on the arXiv pre-print server.
