A globular cluster glitters with starlight in a new photo from the Hubble Space Telescope.
."These clusters orbit around the galactic center, but far above and below the pancake-flat plane of our galaxy, like bees buzzing around a hive."
In the new Hubble photo, the interstellar dust particles scatter blue light, causing only the redder wavelengths from the cluster to come through to our view. The brightest red stars in the photo are massive, aging giants several times larger than. The bright blue stars in the photo are not part of the cluster; they're located in the foreground of the image, unobscured by interstellar material.
The globular cluster Terzan 12 lies 15,000 light-years from Earth. It is nestled deep in the Milky Way, in the constellation of Sagittarius. Its aging stars appear bright red due to the clouds of interstellar dust and gas that obscure our view.

Should the Next Big Observatories Be Built on the Moon?As the next round of giant observatories nears completion, astronomers are starting to ponder what comes next. One exciting location to consider is the Moon. There's no atmosphere on the Moon, so a lunar telescope would act like a space telescope. Still, solid ground, lower gravity, and potentially human astronauts are available to do maintenance and make upgrades. A new paper reviews different kinds of telescopes that could be built on the Moon and their unique advantages over Earth- or space-based instruments.
