The open cluster Westerlund 1, showcased in this new Webb Picture of the Month, is located roughly 12 000 light-years away in the southern constellation Ara (the Altar) where it resides behind a huge interstellar cloud of gas and dust. It was discovered in 1961 from Australia by Swedish astronomer Bengt Westerlund. Westerlund 1 is an incomparable natural laboratory for the study of extreme stellar physics, helping astronomers to find out how the most massive stars in our Galaxy live and die.

  1. For human colonization we need to look elsewhere tho, someone already planted a flag there.

  2. This looks like a bird’s-eye photo of a big city with a star filter, light lines look like roads while stars are the buildings

  3. Something about diffraction spikes makes stars look more exotic. This image is full of ’em. It’s beautiful.

  4. I get that Webb’s hexagonal streaks can be considered charming, idiosyncratic, and novel, but does anyone else get the feeling that they ruin otherwise pristine views?
