Berlin, October 1 : A thorough survey using the NASA/ESA Hubble Space Telescope has observed around 14 million stars in 69 galaxies, which has given astronomers clues about how stars form.
The detailed study, called the ACS Nearby Galaxy Survey Treasury (ANGST) program, explored a region called the Local Volume, where galaxy distances range from
6.5 million light-years to 13 million light-years from Earth.
Some galaxies were found to be full of ancient stars, while others are like sun-making factories.
A typical galaxy contains billions of stars but looks smooth when viewed through a conventional telescope because the stars appear blurred together.
