M 28
M 28
Messier 28 (M28) is a globular cluster located in the constellation Sagittarius, about 18,000 light-years from Earth. It spans roughly 60 light-years across and shines at an apparent magnitude of 7.7, making it visible through binoculars or a small telescope.
It contains hundreds of thousands of ancient, metal-poor stars, and is estimated to be around 12 billion years old. M28 is notable for being the first globular cluster where a millisecond pulsar was discovered. It's best viewed in the summer months from the Northern Hemisphere, near the star Kaus Borealis in the Sagittarius Teapot asterism.
