A cluster of 3,000 stars known as Westerlund 2 in the #constellation Carina. @NASA released this image on the eve of the 25th anniversary of the launching of the #Hubble Space Telescope. "This is a really new birthplace of stars," Jennifer Wiseman, senior project scientist for Hubble, said of the new image. "The cluster is only about two million years old, which in stellar terms is very young. And it contains some of the galaxy’s hottest, brightest and most massive stars that we know of." #space #galaxy
